Rubus is a member of Rosaceae family where its natural habitat is in open areas of lowland and upland forests. Rubus has been reported found in Mount Kembang which is situated in Wonosobo, Central Java, but the number of species was unclear. The objective of this study was to investigate the Rubus diversity in M. Kembang and its uses by local people. Sample collecting was carried out using explorative methods on the slopes of M. Kembang. Uses information was obtained by interviewing the local people. The data were analyzed descriptively to provide species description along with their uses and potential in biological research. The result showed that there were four species of Rubus in M. Kembang, R. rosifolius J.E.Smith, R. chrysophyllus Reinw. Ex Miq., R. fraxinifolius Poir., and R. moluccanus L. with altitudinal distribution ranging from 945 m to 1,387 m above sea level. Among these four species R. rosifolius is the well-known one, that people sell the fruits in its fruiting season in the local market. Based on the literature some Rubus species in other areas in Java have potential as fresh fruits, source for making fruit jam, traditional herbal drink to cure diarrhoea and dysentery, or as ornamental plants. A few studies showed that the fruit extract of R. rosifolius has potential for natural dye in cosmetic products.

Common carp “Majalaya”; Chromosome variation; Karyotype
id
Common carp (Cyprinus carpio Linnaeus 1758) is grouped into Family Cyprinidae and Order Cypriniformes. One of Indonesian common carp which is commonly domesticated in Indonesia to fulfil consumer needs of animal protein is “Majalaya”. Even though the common carp “Majalaya” is extensively domesticated to meet market demands, any comprehensive study on the fish chromosomes has not been investigated. Chromosome study on the common carp “Majalaya” is quite important related to breeding program including certification process. The objective of this study was to study karyotype of the common carp “Majalaya” collected from UKBAT Cangkringan, Yogyakarta. Chromosome preparation of the common carp “Majalaya” investigated in this study was a splash method with blood cell cultures. The results revealed that the common carp “Majalaya” has diploid chromosome number (2n) = 98 classified as 12 (6 pairs) metacentric chromosomes and 86 (43 pairs) telocentric chromosomes displaying karyotype formula 2n = 2x = 98 = 12 m + 86 t. However, sex chromosomes of the common carp “Majalaya” could not be identified in this study. In addition, the variation of total length chromosomes of the fish is between 1,052 μm and 3,299 μm. On the basis of R value (3,079 ± 0.093), the common carp “Majalaya” has chromosome variation size

Diversity; Fish; The Boyong-Code River; Introduction
id
The diversity of freshwater fishes which inhabit in the river of Daerah Istimewa Yogyakarta is not yet well documented. Complete documentation is needed as starting point and continuous research on the fish diversity in DIY. Boyong-Code River flows across the DIY, and it upstream is located on the hillside of Merapi volcano. The Code River upstream is called Boyong River. The research was aimed to acquire data about the diversity of fish fauna along the Boyong-Code River in the DIY. Further, the research purpose is to know which species are rare, potential for aquaculture, and introductive. Samples are taken along the Boyong-Code River starting from upstream to downstream. Samples were collected using Purposive Random Sampling methods with fishnets. Sampling area generally divided into three location i.e., upstream, middle-stream and downstream. Species diversity of fish in the Boyong-Code River is consisted of 24 species, with 5 introductive species. There are eleven native fish species which are potential for cultivation (aquaculture), i.e.: Barbodes binotatus, Mystacoleucus obtusirostris, Rasbora lateristriata, Rasbora argyrotaenia, Barbonymus balleroides, Osteochilus vittatus, Hampala macrolepidota, Anabas testudineus, Channa striata, Clarias leiacanthus and Clarias batrachus. The Boyong-Code River is a decent habitat for fishes. Many introduced fishes starting to invade the Boyong-Code River intentionally or unintentionally by human

Ghrelin; Stomach; Obesity; Immunohistochemistry
id
Obesity is one of major nutritional problems in the world. Obesity is very dangerous, especially when concentrated in the abdomen, because it is closely linked to various diseases such as diabetes, hypertension, heart disease, which can to causing death. This study aims to identify the nature and distribution of ghrelin on gastric endocrine cells in the obese rat (Rattus norvegicus) by using immunohistochemical techniques. The results will strengthen the understanding of the role and function of ghrelin as an alternative therapeutic target on obesity. The research used gastric tissues of ten obese and control rats which were stained with avidin-biotin-peroxidase complex method of immunohistochemistry. The results showed the existence of two types of ghrelin-producing cells (open and closed types) on the gastric mucosa of control rats, and only one type of ghrelin producing cells (open type) in obese rats. The intensity of ghrelin immunoreactive positive cells was detected weak in obese rats, but very strong in control rats. Ghrelin endocrine cells mainly distributed in the basal part of the gastric mucosa of the fundus parts, with a very small number in obese rats, but highly abundant in control rats. This study confirmed the decrease of the ghrelin synthesis and secretion in obese rat (Rattus norvegicus) at the cellular level. The decrease of ghrelin synthesis is characterized by a reduction on the number of ghrelin producing cells, the disappearance of the close type of ghrelin producing cells, and the low activity of protein synthesis in the ghrelin producing cells. Ghrelin endocrine cells distributed mainly in the basal part of the gastric mucosa, especially in the fundus parts.

en
Phalaenopsis “Sogo Vivien” is an orchid hybrid with mini size plant body, and exhibits numerous beautiful pink flowers, that is ideal as ornamental pot plant. Some plants of this orchid exhibit variegated leaves that improve the beauty of the plant, not only because of the flower but also as attracted leaves. This orchid has high economical value, but mass propagation of this orchid has not established yet. An effective method to propagate both the normal and variegated plants is worth to be generated. The objective of this research was to produce a large number of P. “Sogo Vivien” plants, including the variegated plants. The method used seeds from self pollinating variegated plant, and flower stalk nodes. The seeds were sown on three various medium: VW, NP and MS, and flower stalk nodes were planted on VW + BA 10 mg l-1 + active carbon. The results showed that the best medium for in vitro culture of P. “Sogo Vivien” was NP medium, in which all seeds could grew into plantlets. Most plantlets emerged from the seeds were non variegated, only one plantlet out of 1344 seeds was variegated (0.007%). Although all emerged plantlets from flower stalk exhibited variegated leaves. Particularly, the plantlets arised from the second and third basal nodes of flower stalk showed the highest growth rate than that from the other nodes. Histological analysis showed that at 11-13 days after shoot segment plantation on NP medium, the shape of apical cells in the nodes was changed, then followed by the change of cell shape in the basal part of the nodes, produced bipolar pattern, then gradually developed into shoot. These results suggest that mass propagation could be achieved using seed culture, but to get the variegated phenotypes, the second and third nodes of flower stalk from variegated plant were the best explants to be used.

Moringa oleifera; Muntingia calabura; antibacteria; extract; seed
id
Moringa oleifera and Muntingia calabura leaves have been reported to have an antibacterial activity that could inhibit the growth of gram positive and negative bacteria. However, the antibacterial activity of mixed extracts of M. oleifera seeds and M. calabura leaves has not been widely reported. The purpose of this study was to test antibacterial activity of the mixed extract of M. oleifera seeds and M. calabura leaves on the growth of Pseudomonas aeruginosa and Bacillus subtilis. The experiment was conducted by agar disc diffusion method using three groups of extract treatments i.e. M.oleifera seeds extract, M.calabura leaves extract, and mixed extracts of M. oleifera seeds and M. calabura leaves with a ratio of 1: 1 (v / v). The extraction of M. oleifera seeds and M. calabura leaves was conducted by soxhlation method and using ethanol as solvent. The three groups of extract treatments with a concentration of 400 ppm, 800 ppm, 1200 ppm, and 1600 ppm were tested on P. aeruginosa. The antibacterial activity test of M. oleifera seed extract against B. subtilis carried out at the level of concentrations i.e. 150 ppm, 300 ppm, 450 ppm, 600 ppm, and 750 ppm, meanwhile, M. calabura leaves extract was done at concentration 1500 ppm, 3000 ppm, 4500 ppm, 6000 ppm, and 7500 ppm. The result showed that the three groups of extract treatments possess antibacterial activity against P. aeruginosa. The mixed extracts of M. oleifera seeds and M. calabura leaves with a ratio of 1: 1 (v / v) at level concentration of 400 ppm and 800 ppm were tested against P. aeruginosa significantly increased, and at concentrations of 1200 ppm and 1600 ppm significantly decreased the inhibition diameter of bacterial growth than the other extracts treatments. The antibacterial test results of M.oleifera seeds extract and M.calabura leaves extract against B. subtilis shows that increased concentrations of the extract significantly increase the inhibition diameter of bacterial growth especially at high concentrations ( 600 ppm and 750 ppm) on M. oleifera seeds extract, as well as 6000 ppm and 7500 ppm in M. calabura leaves extract.

Inasua is a traditionally product of wet salt fish fermentation produced by Teon, Nila and Serua (TNS) Communities in Central Maluku, Indonesia. The community made this fermented fish to anticipate the lean time when fisherman could not go to sea. The fish that used as inasua raw material is demersal fishes that live around coral reefs, such as Samandar fish (Siganatus guttatus), Gala-gala fish (Lutjanus sp.) and Sikuda fish (Lethrinus ornatus). The objective of the research was to isolate and characterize of bacterial indigenous in Inasua from three producers in Seram Island. The measurement of pH from inasua samples were 5.9, 5.0 and 5.8, respectively. The highest number of lactic acid bacteria was found from Gala – gala inasua was 2,5x107 cfu/g sample. Isolation of all isolates bacteria from inasua showed that a total of 7 isolates of bacteria was obtained from Samadar inasua, 9 isolates from Gala-gala inasua, and 7 isolates from Sikuda inasua. From a total of 23 isolates, only 6 isolates had characteristic as lactic acid bacteria that were Gram positive, negative catalase, and cocci shape. The microscopic characteristics of the isolates are coccid in pairs or uniforms which combine to form tetrads. Carbohydrate utilization test of selected isolate by using API 50 CHB kit indicated that 13 carbohydrates are fermented by these isolates after incubation for 48 hours. The research was concluded that the dominant bacteria in inasua sample is cocci-lactic acid bacteria.Keywords : fermented fish, inasua, lactic acid bacteria, MRSA medium

diabetes mellitus; MnSOD gene; retinopathy
id
Complications of diabetes mellitus (DM) include diabetic retinopathy (RD) both non-proliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR). The development of RD depends on environmental and genetic factors. MnSOD gene (manganese-superoxid dismutase) is one of the candidate risk factors gene for RD. The presence of V16A MnSOD gene polymorphism results in decrease of mitochondrial MnSOD enzymes expression and triggers the oxidative stress. Hyperglycemia in DM increases oxidative stress in tissues, including the retina resulting in metabolic abnormalities in the retina, which play a role in the development of DM complications, namely diabetic retinopathy. In Indonesia, especially the Javanese tribes in Yogyakarta, there has never been any research on MnSOD gene polymorphism in type 2 diabetes patients with and without retinopathy. Subjects were Poly Endocrine patients and Eye Polyclinic patients of Dr. Sardjito’s General Hospital, 121 subjects consisting of 63 type 2 DM patients without retinopathy were group 1 (KI) and 58 type 2 DM patients with retinopathy were group 2 (KII) (20 NPDR subjects and 38 PDR subjects). V16A polymorphism of MnSOD gene from leukocytes DNA was analyzed by PCR-RFLP method. From 121 DM subjects, 70 subjects with VV genotype were found, 50 subjects with VA genotype and 1 subject with AA genotype. From 63 non-RD DM subjects, 22 subjects with VA genotypes and 41 subjects with VV genotype were found, while in DM with retinopathy (non-PDR, n = 20) found 6 subjects with VA genotype and 14 subjects with VV genotype, and in DM with retinopathy (PDR, n = 38) found 1 subject with AA genotype, 22 subjects with VA genotype and 15 subjects with VV genotype. In DM with retinopathy (NPDR and PDR, n = 58), 1 subject was found with AA genotype, 27 subjects with VA genotype and 29 subjects with VV genotype.

The rapid increase in human population reduces land productivity in urban areas. Verticulture is a way of planting in a vertical arrangement, such as for Capsicum frutescens L. This study aimed to examine the root anatomy and growth responses of C. frutescens L. Fourteen days old seedlings were grown in polybags on the ground and into vertical pots made of paralon pipe. Watering was given for every day, once in 3 days, and once in 6 days were apllied for 35 days, at elevation of 0 cm, 25 cm, 50 cm and 75 cm. The lower watering supply decreased the root diameter due to the thinner of cortical, xylem and stele tissues. Decreased in plant height, leaf number, length-width of leaves, and fresh and dry weight of root-shoots were also observed in low watering plants, but there were increases in roots length and leaves chlorophyll content. The xylem was less developed in plants at higher position compared to the lower positon and this was more detected in plants with less watering. Decreasing plant growth occurs in conditions of water shortage and the higher plant layout on paralon, while root vascullar tissue was less developed in less watering and higher position plants.

Flower-insect relationship, Rhododednron, Botanic Garden
en
The Rhododendron-insect relationship was quite well studied in the northern hemisphere. However, information on the flower-insect relationship of the Indonesian Rhododendron was limited. This study aims to find the interaction between Rhododendron inundatum Sleumer collected in Bali Botanic Garden and its flower-visiting insect. The study was conducted by observing insect visitation to the flower of R. inundatum for 1 hour a day and repeated for nine days. Data analysis was conducted by calculating the Visitation Rate (VR) of each visitor taxa to determine its frequency. Study result showed that R. inundatum in Bali Botanic Garden was visited mainly by Chrysopa sp., as well as members of the Vespidae, Curculionidae, Muscidae, Drosophilidae, and Tephritidae. The result of this study was dissimilar with the previous study of white-flowered Rhododendron, which was mainly visited by moths.

sea turtles; Bali; hatcheriesl breeding farm
id
Sea turtle has been widely consumed in Bali since the 1970s mostly for religious activities. After many international critics, various stakeholders (governments, NGOs, environmentalists and Balinese people) developed the so-called “turtle conservation centre” as means to conserve sea turtles. The purpose of this study is to assess the effectiveness of those conservation efforts by evaluating the conservation activities of each conservation centres. We visited five sea turtle conservation centres in Bali; all were named as captive breeding centres or farm. The captive breeding centre is misleading as there is no activity related to captive breeding, mostly hatchery. Some of the eggs were not even originated from Bali, and the centres were sometimes used as the source for sea turtle for religious purposes. Based on the scoring, only one centre is active in terms of conservation.

The objective of the study was to determine the effect of cadmium on sperm quality and fertilization of C. carpio L. Sperm and eggs were collected by abdomen striping from the mature testis and ovary of C. carpio L. This study used one control and four treatment groups of variation on the cadmium concentration (0, 50, 100, 150, and 200 ppm) with eight replications. Sperm motility (mass motility, mass motility duration, and individual motility duration) and viability were measured after three to four seconds of incubation in the water. The percentage of fertility success was calculated by observing embryo development after the eggs were mixed with sperm and incubated in the water for 72 hours. The success of the fertilization process was indicated by a color change of the egg that darkens after successful fertilization, and white-milk if failed. The data were analyzed using analysis of variance (α = 0.05). The results of this study indicate that exposure of 50 ppm cadmium and control group shown success in term of sperm quality (motility and viability) and fertilization, but at 100 ppm or more decreased the sperm quality and fertilization rate. It can be concluded that cadmium exposure decreases sperm quality and fertility at 100 ppm or higher concentrations.

Annonaceae species of Purwodadi Botanic Garden collections from East Java encountered problems in species identification based on morphological characters. In addition, the unavailability of molecular data to support identification based on morphological characters hinders accurate identification of species. The aim of this research is to discern phylogenetic of Annonaceae species from East Java collections of Purwodadi Botanic Garden based on coding and non-coding sequence DNA. Annonaceae species used in this study are 30 species, includes outgroup from family of Magnoliaceae. Materials for DNA analysis were young leaves which were processed through DNA extraction, DNA amplification through PCR technique, DNA sequencing and data analysis with Maximum Likelihood (ML), Maximum Parsimony (MP) and Neighbour-Joining (NJ) method analysis. The results show that phylogenetic tree is divided into two subfamilies, i.e. Annonoideae and Malmeoideae. The topology of phylogenetic tree from three DNA molecular marker shows that non-coding sequence DNA (trnL-F molecular marker) has the best grouping of relationship and be able to explain the relationship between species of Annonaceae than rbcL and matK molecular marker as coding sequence DNA. Bootstrap value of trnL-F tree is very weak to high (36-100%) while rbcL is very weak to weak (17-63%) and matK tree is high (98-99%).

The suitability of corn kernel as raw material to produce miso fermented by rice-koji containing Aspergillus oryzae and Rhizopus oligosporus has been investigated. The optimization was conducted on two important factors in miso production namely mold composition in rice-koji and salt concentration. The mold composition was prepared by inoculating the spores of 2% A. oryzae, 2% R. oligosporus, and 2% the mixture of both in a ratio of 1:1, 2:1, and 1:2 (v/v) into different rice media. The mold composition was optimized to produce rice-koji with high α-amylase and protease activity. Different NaCl concentrations of 10%, 15%, and 20% were subjected to optimization process and added to each mixture after five days of fermentation. The salt concentration was also optimized to produce corn kernel miso with high glucose and high dissolved protein concentration. The result showed that rice-koji containing A. oryzae and R. oligosporus in the ratio of 1:1 had the highest α-amylase and protease activity of 0.42 U/mL and 0.45 U/mL respectively. In addition, the presence of 10% NaCl in corn kernel miso fermented by A. oryzae and R. oligosporus in the ratio of 1:1 exhibited the highest glucose and dissolved protein concentration of 0.64 mg/mL and 8.80 mg/mL respectively. The optimized corn kernel miso by A. oryzae and R. oligosporus in the ratio of 1:1 with 10% NaCl was subjected to nutrient content analysis and compared to the result before the corn kernel was fermented. The nutrient content analysis showed nutrient enhancement after corn kernel was fermented and transformed into a miso. Glucose, dissolved protein, and fat content increased 6.74, 1.34, 7.63 times respectively. This study concludes corn kernel could be utilized to produce a novel corn kernel miso for dietary diversification and for improving nutritional and health status.

Indonesia has high biodiversity, one of them is the diversity of giant freshwater prawn (Macrobrachium rosenbergii de Man, 1879). The giant freshwater prawn was easy to reproduce and has high nutritional value. This study was conducted to determine the morphological variation of inbreed and outbreed of Probolinggo and Mahakam (Mama, Gogo, Goma, and Mago) populations that was developed in Unit Kerja Budidaya Air Payau Balai Budidaya Udang Galah (UKBAP BBUG) Samas as a basic for seed selection. Research of morphological variation carried out by observing 12 morphological characters, four meristic characters and 52 morphometric characters in four populations. Analysis of basic morphometric characters using a statistical program to determine the linear regression and the significance of parameters. Analysis of morphological characters using a statistical program to make dendrogram showing the similarity of four populations. The result of morphometry shows that the ratio of cephalothorax and abdomen of Mago and Goma is lower than Mama and Gogo. When viewed from the ratio of the carapace and rostrum length, Mago produces the longest rostrum. So, when only carapace length is compared to abdomen length, Mago showed the greatest value. Gogo has the highest ratio of cephalothorax and abdomen, while Mago has the highest ratio of carapace and abdomen among populations. Morphological data analysis showed that Gogo and Goma had reached 76% similarity, Goma and Mama have a similarity of 68% while Mago has 52% similarity with another three populations.

Sea Fern (Acrostichum aureum L.), which typically grows in mangrove ecosystem, has two distinguished leaves which are fertile leaves (rich in spores) and sterile leaves (no spores). Those leaves are known rich in phenolic compounds. Flavonoids, moreover, which belong to class of phenolic compound, have antioxidant activity. This study aims were to analyze the phenolic content, flavonoid content, and antioxidant activity of fertile leaves, sterile leaves, and spores of sea fern which grow in mangrove ecosystem that is located in Kulon Progo, Yogyakarta. Leaf and spore samples were extracted using ethanol solvent. Then, total content of phenol and flavonoid were measured by spectrophotometry, while the antioxidant activity was measured by DPPH method. The results showed that the phenolic content of fertilized leaves and sterile leaves did not show a significant difference. In other hand, the spores sample showed highest both of flavonoids content (2.32 mg/mL) and the antioxidant activity with the IC50 value was 23.25 ppm. Thus, the ethanolic extracts of spores of sea fern sterile leaves showed the highest flavonoid content and could be categorized as a very strong antioxidant.

East Java’s forest has a less ideal area based on predetermined requirements. Therefore, rehabilitation was done to meet these requirements and to improve the quality of existing forests. This research was conducted to identify the character of protected forest in Resort Pemangku Hutan (RPH) Sentul area, about vegetation structure and abiotic factor of lowland forest area with low rainfall. The research was conducted by explorative method with plot making for tree plant, sapling and ground cover to inventory and determine the forest vegetation structure inside the area, also by measuring the environmental parameters (temperature, humidity and light intensity) and making soil sampling to analyze biophysical condition. Data were analyzed descriptively both on vegetation condition and physical condition of land and its environment. The result showed that there were identified 84 species from 39 plant families either as trees, sapling or ground cover, with species of Moraceae as the largest contributor. The diversity index of the three types of vegetation shows a medium categorized, while the index of evenness indicates a good categorized that is close to one. Based on the existence of exotic species, especially on ground cover, within protected forest areas, this area has been degraded although not large. However, the physical condition of the soil and environmental conditions in the forest still indicate that this area is still quite good when used as a reference area on rehabilitation program with similar geographical conditions.Keywords: vegetation structure, soil characteristic, low land forest, RPH Sentul Probolinggo

Cyclea barbata Miers.; green grass jelly; immunomodulator; antioxidant; DPPH
en
Green grass jelly (Cyclea barbata Miers.) is known for its benefit to human health especially in supporting body’s immune system and wellness. This research aimed to determine immunomodulatory and antioxidant activity of green grass jelly leaf extracts in vitro. Old leaves were collected as sample then dried and ground to powder. The extraction was done with sohxletation using three different solvents, chloroform, ethyl acetate, and ethanol. The immunomodulatory activity was evaluated by treating the crude extracts at concentrations of 50, 100, and 500 mg/mL on macrophages of rat in vitro. Macrophage cells separated form peritoneal fluid used RPMI medium. Phagocytosis activity and phagocytosis capacity of macrophages were performed in vitro using latex beads that suspended in phosphate buffered saline (PBS). The antioxidant activity was measured by spectrophotometry technique with 1,1-diphenyl-2-picrylhydrazyl (DPPH) solution. All treatments were done three replicates. Detection of the bioactive groups of the extracts was done by Thin Layer Chromatography (TLC). The results showed that ethyl acetate extract has the highest phagocytosis activity followed by chloroform extract and ethanol extract, respectively. Optimum concentration was reached at 100 mg/mL of ethyl acetate extract. The ethyl acetate extract was also the highest antioxidant activity index 7.7 followed by both extracts of chloroform and ethanol similar index value of 6.25 and 6.3, respectively. The ethyl acetate extract has a high immunomodulatory activity and antioxidant activity which contained phenolics, flavonoids, tannins, and terpenoids.

Single Garlic Oil Extract (SGO); the zone of inhibition; Pseudomonas aeruginosa
en
Nosocomial infection caused by Pseudomonas aeruginosa bacteria is hard to be treated since the infection transmission is fast and it is resistance to the antibiotic. Antibiotic resistance in the bacteria can be treated with various natural ingredients from plants and one of the plants is single garlic. Single garlic contains organosulfur compounds in form of alliin, allicin, and ajoene. This research aimed to analyze the potential of single garlic oil (SGO) in inhibiting the growth and the damage of membrane of P. aeruginosa bacteria in in vitro with disc diffusion method by giving treatments of essential oil extract in concentration of 25 mg/ml, 50 mg/ml, 75 mg/ml and 100 mg/ml, and 1% dimethylsulfoxide (DMSO) as the negative control and Ceftazidimeof 30 µg/ml as the positive control. The damage of the bacterial cell membrane was observed with Scanning Electron Microscopy (SEM) with a magnification of 25000X. The result of the measurement of the zone of inhibition was analyzed using one-way ANOVA. The research results indicate that SGO could inhibit the growth of P. aeruginosa bacteria with strong criteria, which was in a concentration of 100 mg/ml.

en
Continuous water uptake from soil via the root system and it transport into the leaves system is a basic mechanism in plants to maintain growth and reproduction. Consequently, sustaining soil moisture to keep water supply into the plants should continuously occurred to maintain growth. Under condition of global warming scenario and robust agricultural practices, soil organic carbon which plays as a key for soil moisture and fertility are continuously diminished. This condition could subsequently endanger the growth of shallow rooted plants, such as vanilla. To mitigate the impact of global warming and robust agricultural practices, enhancing carbon sequestration to inhibit water loss is regarded crucial. However, although mulch materials are locally available in most land crop plantations, those materials are rarely viewed as functional for maintaining soil moisture. Both water stress and mulching might have not been seriously anticipated in conventional agricultural practices. For example, continuous decreased in yield of vanilla plants are usually handled by applying pesticide or fertilizer, without addition of mulch. The objective of this review was to gain a better understanding of soil moisture to increase vanilla growth and reproduction. This review found that mulching could reduce evaporation, increase soil organic carbon and soil fertility. It is concluded that intensification of mulching could enhance sustainability of vanilla plantations.

Indonesia is the second largest mega biodiversity of the world. One of the forest resources are soil insects. Soil insects improved the soil physical properties, added organic material content, and used as bio-indicator of environmental conditions of conservation areas, forests, or mountains. The aim of this research was to get information about the diversity, dominance, and similarity index of soil macro insect in Alas Purwo National Park, Banyuwangi, East Java, Indonesia in 2017. Locations were selected based on purposive random sampling considering 2 habitat types; coastal forest path and tropical rain forest path. The method of this research was used pitfall trap. Insects were identified at Laboratory of Ecology, Biology Department, Faculty of Science and Technology, Airlangga University, Surabaya. The results showed that the diversity index of soil insects in the coastal forest path was 1.611 and in path of tropical rain forest was 0.855. It means that the diversity of soil macro insect in coastal forest path were medium and in path of tropical rain forest was low. The Dominancy index of coastal forest path was 0.334 and in path of tropical rain forest was 0.433. It means that the community was stable, there was no species domination. The similarity index of soil insects in both paths have a 58.8%, was a unity of the same community.

The objectives of this research were to examine the effect of Sechium edule ethanolic extract in insulin and Malondialdehyde (MDA) levels in streptozotocin (STZ) induced diabetic rats. Type 1 diabetic rat were obtained by intraperitonially injected with multiple low dose STZ (MLD-STZ) 20 mg/kgBW for 5 days. The animals were divided into 5 groups: untreated rats in group (K) were considered as negative control, MLD-STZ induced type 1 diabetic rats in group (S) were considered as positive control. In another 3 group (A, B, C) type 1 diabetic rats were orally treated with three doses of S. edule ethanolic extract (14, 28, 42 mg/kg BW) for 7 days. The animals were sacrificed in two days after last treatment, serum were collected for measuring of the insulin concentration by ELISA method. Level of MDA on kidney, liver and pancreas were measured by TBA method. The treatment with S. edule ethanolic extracts unable to increase of insulin yet but the treatment with 42 mg/kg BW of S. edule ethanolic extract showed significantly decreased MDA levels on liver but not significant on kidney and pancreas.

Under the Malaysian Universities Act 1971, Higher Learning Institutions are encouraged to set up museums that could support teaching and learning at the institution. With that provision, the Universiti Tun Hussein Onn Malaysia (UTHM) Natural History Repository was formed in 2014, to support the newly developed BSc Program called Biodiversity and Conservation. Under the Faculty of Applied Science and Technology, Centre of Research - Sustainable Uses of Natural Resources (CoR-SUNR), develops and organizes the repository. Currently the repository is sited at a shoplot building in Parit Raja Campus that had been modified as part of campus expansion plan. The process of converting this shoplot building into functional gallery/storage space introduced a new challenge in pest management. The goals were to ensure whatever pests already present are eradicated, determine ways to seal out future pests, stabilize the condition to decrease pest infestation, and establish a monitoring program. Baseline pest data were collected via trapping throughout the repository spaces before, during, and after retrofit construction. Data from trapping were used to assess pest problems, and actions to eliminate these pests were initiated. A year-long survey of pests was performed after staff and collections occupied the building. The results showed variation in pest diversity and populations. Having succeeded in controlling insects pest problems at UTHM Natural History Repository would lead to better teaching/learning experience for graduates as well as promoting public awareness and education especially among young public on biodiversity.Under the Malaysian Universities Act 1971, Higher Learning Institutions are encouraged to set up museums that could support teaching and learning at the institution.

dwarf snakehead; genetic characterization; mtDNA 16S; nucleotide composition
en
Indonesia has a high marine and freshwater biodiversity including freshwater fish biodiversity. One of freshwater fish which is commonly consumed by Indonesian people is dwarf snakehead (Channa gachua Hamilton, 1822). However, research on genetic characterization, especially the composition of mtDNA 16S nucleotide of dwarf snakehead has poorly understood. Therefore, the aim of this study was to determine the composition of mtDNA 16S nucleotide of dwarf snakehead as a part of genetic characterization of the fish species taken from Keji River, Magelang, Central Java which has not been previously examined. This study analyzed 16S mt-DNA of two samples of dwarf snakehead from Keji River (KTS-01 and KTS-02). In addition, two sequences of Channa gachua with accession number KU986900, KU238074, and HM117234-HM117238 taken from GenBank were used as a comparison. A method used in this research was a PCR method and primers used in this research were 16Sar and 16Sbr. The results revealed that the average of nucleotide composition T, C, A and G of the fish species was 23.04%, 25.13%, 29.06% and 22.77% respectively whereas the average rate of nucleotide composition A+ T and G+ C was 52.10% and 47.90% respectively. The two dwarf snakehead had similar T and C composition but different in A and G composition. In addition, the G+C content in KTS-01 and KTS-02 had the highest frequency compared to other dwarf snakehead taken from GenBank. From this finding it could be assumed that there is genetic variation between the two dwarf snakehead from Keji River which is important genetic data for breeding program of the fish species in the future.

en
Diversity of macrofungi is widely studied because of its role as decomposer, and highly reported of its potentially using for foods, agricultures, medicinal purposes, and bioremediation. This study was carried out to consider sampling methods for macrofungi exploration especially in Turgo tropical forest ecosystem. There were two sampling method models which adequately bring our macrofungi collection to have valid data. The first is adaptive sampling which includes fixed-size plots where prior we decided how many tracks, plots, or what size to examine at each site to help keeping our focus on track. By having a fixed plot, we allowed ourselves to find our macrofungi and work on the identification process thoroughly without racing against the time as much. Then we can obtain frequency, distribution, density and others ecological quantitative data by sampling plots. Another way, we can choose opportunistic sampling, we mean carefully walking on through chosen site as study area and collecting conspicuous sporocarp of macrofungi. This method needs no plots and does not produce any quantitative data but looking for many more diversity on macrofungi. The way of sampling, depends on the duration of observation and the purposes of the research. According to the consideration result, we concluded to choose the adaptive sampling method to explore the macrofungi in Turgo tropical forest ecosystem.

In Indonesia, the development of oil palm plantations has been going on a pervasive way; they covered about 14.03 million hectares in 2017. This massive coverage of land might then generate a tremendous amount of biomass per year, both in the form of both solid and liquid wastes. The processing of fresh fruit bunches (FFB) in palm oil mill (POM) produces wastes that primarily in the form of empty fruit bunches (EFB), which is amounting of up to 25% (w/w) of FFB. It has been being indicated that EFB contains a considerable amount of silica (Si) which attracts the Indonesian Research Institute for Biotechnology and Bioindustry (IRIBB) to investigate the potential use of EFB as a source of bio-available Si, in the form of H4SiO4 (mono silicic acid, BioSilAc). The experiment was carried out at Sungai Mirah Minting Estate, PT Bumitama Gunajaya Agro-Central Kalimantan. The EFB material was obtained from POM and chopped into 2.5-5.0 cm in size. A four-week bio-decomposition process was employed by using bio-decomposers containing Trichoderma pseudokoningii, T. polysporum, and Phanerochaete chrysosporium. Chemical analyses of composted EFB were conducted before and 28-days after decomposer application. The presence of Si in the compost was observed by scanning electron microscopy (SEM). The effect of Si-containing EFB compost on the immature and mature oil palm was evaluated. Seven treatments, i.e. combination of EFB compost and BioSilAc application with reduced-dosages of NPK fertilisers were arranged in a random block design with three replicates. The results show that large quantities of silica bodies attached to the surface of EFB fibres and amounting to 0.44% soluble Si. The FFB data indicated that the application of 75% NPK + 500 kg composted EFB + 2 L BioSilAc/ha/year on a five-year-old plant resulted in higher yield than that obtained from 100% standard dosage of NPK. The study also revealed that the application of EFB compost reduced 50% of BioSilAc dosage.

Purwoceng; in-vitro culture; rooting induction
en
Purwoceng (Pimpinella pruatjan Molk or Pimpinella alpine KDS) belongs to the Apiaceae family, is an endemic plant in mountainous areas such as the Dieng Plateau, Pangrango Mountain, and mountainous areas in East Java. Parts of the plants, especially roots are efficacious as aphrodisiacs, diuretic drugs and tonics. Based on CITES, this plant belongs to the category of endangered species, so its presence is very rare in nature. This scarcity occurs due to the purwoceng exploitation in nature as traditional herbal medicine without any cultivation or rejuvenation. In situ conservation efforts are almost impossible because the original habitat of this plant has become extinct. Thus, ex situ conservation is more suitable to be applied, by using in-vitro culture techniques. Therefore, a research study is needed on the development of tissue culture techniques in the production of the seeds. Methods of data collection in this study was conducted by literature studies. Therefore, ex-vitro root induction techniques are applied currently, namely rooting induction. The content of the chemical compounds and various properties make purwoceng as a commodity in the raw materials of drugs that have great potential to promote industrial players in the economic field. Based on the results from the literature, the authors can conclude that the potential of purwoceng plants is quite large, but still constrained by the scarcity of seed supply so the application of ex-vitro root induction techniques in in-vitro culture can be a solution in limitation of supply of purwoceng crops for industrial scale.

Cashew fruit peel is a waste produced from the cashew nut industry, and it has not been utilized optimally yet. Cashew peel extract has the potential to be used as a contraceptive agent, which capable of reducing reproductive capacity. However, its side effects on other tissue and organ such as liver not clearly studied yet. This study aims to determine the effect of ethanolic extracts of cashew peel on the histological structure of the white rat liver. In this study, 21 female white rats were used and be grouped for control (6 mice) which were treated with CMCMa 0.5% and 15 mice were treated with peel extract of 500 mg/kg body every day for one month. Liver for examination was collected sequentially at 3rd, 5th, 8th, 11th, and 14th of the estrous cycle. The liver was processed for histological observation and stained with Hematoxylin Eosin and Mallory Acid Fuchsin staining solution. The liver hepatocyte was observed for it abnormality and be scored to calculate the number of cell damage or abnormality. The result showed that peel extract-treated mouse liver was similar to control ones; we did not witness any evidence of fibrosis, pyknosis and cellular necrosis on either control or treated mouse. Statistical analysis by SPSS showed that the p-value between the control and treatment groups was 0.078 (> 0.05) so there was no significant difference between control and treatment. It could be concluded that ethanolic extracts of cashew nuts peel with a concentration of 500 mg/kg body weight caused no effect on the mouse liver histological structure. application with reduced-dosages of NPK fertilizers were arranged in a random block design with three replicates. The results show that large quantities of silica bodies attached to the surface of EFB fibers and amounting to 0.44% soluble Si. The FFB data indicated that the application of 75% NPK + 500 kg composted EFB + 2 L BioSilAc/ha/year on a five-year-old plant resulted in higher yield than that obtained from 100% standard dosage of NPK. The study also revealed that the application of EFB compost reduced 50% of BioSilAc dosage.

en
Peanut (Arachis hypogaea L.) is a food commodity that is widely cultivated in Indonesia. At present there has been no analysis of the relationship between peanut cultivars with phenetic methods based on the morphological properties of the plants. Four cultivars of Arachis hypogaea L. Tuban, Talam 1, Talam 2, and Talam 3 used in this research. Morphological characters data was analyzed by description to construct identification key. Similarity index was counted by Simple Matching Coefficient (SSm) formula based on morphological scoring. Cluster analysis was conducted by UPGMA (Unweighted Pair Group Methods using Arithmetic Averages) method to construct dendrogram. PCA (Principal Component Analysis) were performed to defined role of each morphological character in grouping of accessions with MVSP (Multivariate Statistical Program) v. 3.1 software. The dendrogram showed that four cultivars of Arachis hypogaea L. divided into two main clusters, 4 sub-clusters. The similarity index of clusters is 0.85%.

Rattan is a potential non-timber forest product. It grows in almost all parts of Indonesia, and has been widely used and traded. Indonesia as the largest rattan producer in the world supplies about 85% of world rattan needs. Bukit Lubuk Pekak Forest is part of the Production Forest Management Unit (KPHP) area, Merangin District, Jambi Province. The threat form rattan exploitation is increasing, especially in the Bukit Lubuk Pekak. Therefore, it is necessary to conduct study on the potency of rattan in that area for future conservation efforts. This study aimed to investigate rattan species in Bukit Lubuk Pekak forest, Merangin District, Jambi Province. Information of the potency of rattan is essential to support rattan industries. To complete data of rattan potency from Sumatra, an exploration in this area was carried out in July 2016 in Bukit Lubuk Pekak Forest. The study was conducted by purpossive sampling. Identification on morphological characteristics of rattan were performed on all parts of plants including fruits and seeds (if available). The results showed that there were four rattan genus in Bukit Lubuk Pekak Forest: Calamus, Daemonorops, Korthalsia, and Plectocomiopsis. They consisted of nine species, namely Calamus caesius, C. exillis, C. insignis var. longispinosus, C. laevigatus, C. tumidus, Daemonorops micracantha, D. didymophylla, Korthalsia flagellaris, and Plectocomiopsis geminiflora. Among the nine species, two species that is Calamus caesius and Daemonorops didymophylla have been cultivated for industry raw materials and drug, respectively.

Volcanic activity is a major natural disturbance that can catastrophically change an ecosystem over a short time scale. The eruption of Mt. Agung strato-volcano in 1963-1964 was considered among the most important volcanic event of the 20th century due to its effect on global climate. Studies on vegetation and landscape of Mt. Agung post-1970-1980 has been scarce. The current eruption of Mount Agung in June-July 2018, brought awareness of the importance urge to document the past and current landscape along with vegetation on Mt. Agung. Our study aimed to utilize remote sensing technique to explore the pattern of current (2017) land cover and vegetation density on Mt. Agung and estimate of vegetated areas and whether it has changed from the past. LANDSAT 8 images (www.earthexplorer.usgs.gov/) were used in this study. Supervised classification in ENVI was employed to obtain land use or land cover of the Mt. Agung area. Normalized Difference Vegetation Index (NDVI) was also calculated using the feature in the ARC GIS. Online web-based application, REMAP was used to obtain information on past and present condition of the crater of Mt. Agung to see whether there have been changes in vegetated areas around the crater using REMAP (www.remap-app.org). Results showed there are basically five main landcover that can be recognized namely forest (20758.23 ha), settlement (4058.37 ha), water area (41606.64 ha), open area (15335.64 ha) and farming (34554.78 ha). Our NDVI analysis also resulted in areas with have high density (78836.04 ha), medium density (15490.26 ha) and also no vegetation (31008.24 ha). Using web-based GIS application REMAP, we found that there has been an increase (approximately 1 km2) in vegetation cover from the 1980s to 2016. The changes in vegetation near the crater of Mt. Agung is relatively slow when compared to another volcano such as Mt. Merapi. Remote sensing application has enabled us to obtain information on vegetation change relatively easily compared to conduct an extensive on-ground survey where more time and funding is needed.

Arthrospira maxima and Chlorella vulgaris are contained a high protein and antioxidant levels that can be used as functional foods or supplements to improve health. Furthermore, this material needs to be monitored for safety. The aims of this research were determined the subchronic toxicity test of microalgae A. maxima and C. vulgaris on kidney function. Parameters of this research were creatinine levels, urea levels, kidney index, and histological structure of the kidney glomerular. Besides that, the progression of body weight was observed. Five teen female Wistar rats (Rattus norvegicus Berkenhout,1769) divided into three groups randomly were one control group and two treatment groups using A. maxima and C. vulgaris in the same dose were 2500 mg/kg of body weight. Subchronic toxicity test was conducted by oral gavage every day during 90 days — the measurement of creatinine levels and urea levels on the 30th, 60th, and 90th day. Kidney index and glomerular histology of rat’s kidney was prepared after necropsy at the end of this research. Base on the results, it can be concluded that consume of Arthrospira maxima, and Chlorella vulgaris at 2500 mg/kg of body weight increased creatinine and urea levels. Bodyweight, kidney index, and pathological glomerular cells of histological kidney were still in normal value.

Lima bean (Phaseolus lunatus L.) is a species of beans which originating from the regions of Central America and Andes Mountains. Lima bean in Timor Island is underutilized although these plant growth there and have many variations. This study aims to determine the diversity of lima beans on Timor Island based on morphological characters. Samples were collected by survey methods from three districts on the island of Timor. Morphological traits related to the vegetative and flowering stages and mature seeds morphology were scored using the International Plant Genetic Resources Institute lima bean descriptors with a soft modification. The similarity index is calculated using the General Similarity Coefficient Gower formula. The dendogram is generated from cluster analysis using the Unweighted Pair Group Methods using Arithmetic Average (UPGMA) method. Furthermore, Principal Component Analysis (PCA) was used to determine the role of each morphological character used. The dendogram shows that 23 collected accessions are divided into two main clusters with a 57% similarity index. The two clusters are distinguished based on the presence or absence of secondary colors and secondary patterns in the seed organs. Then, each main cluster is divided into two subclasses based on the character of the pigmentation stem, the length of the terminal leaflets, flower color, and seed type.

The open-pit mining method has a very large ecological impact. It causes the loss of forest vegetation which decreases CO2 absorption. Measuring the amount of carbon stored in plant biomass can represent the amount of CO2 that can be absorbed in the atmosphere. The objective of this research is to determine the carbon sequestration of Albizia saman and Senna siamea in different age classes at PT MHU Busang Jonggon Block, Kukar, East Kalimantan. Estimation of carbon sequestration in the stands of A. saman and S. siamea was carried out by non-destructive methods using biomass allometric equations while in understorey and litter using the destruction sampling. The results showed that the highest carbon absorption value of A. saman was 314.28 tons/ha which appear at six years old stands and the lowest value was 193.31 tons/ha at three years old stands while the highest carbon absorption value of S. siamea was 113.65 tons/ha which appear at nine years old stands and the lowest value was 24.64 tons/ha at three years old stands. A. saman could be more promising plant species than S. siamea according to its higher level of carbon sequestration and their high adaptation level. All data from this study could suggest several information for increasing carbon sequestration level in forest ecosystem as well as achieving forest rehabilitation purpose.

Java has been known in the world of Paleontology as a contributor to the findings of Homo erectus fossils, but there are still other fossil findings that have not been identified until now, especially fossil fishes of the subclass Actinopterygii. This research was conducted to recognize the diversity of the actinopterygians fishes in Plio-Pleistocene of Java and to determine the diagnostic characters of each taxon group of fossils in the Plio-Pleistocene of Java. The study was carried out using comparative anatomical methods with present-day specimens and fossil findings collection of the Laboratory of Bioanthropology and Paleoanthropology, Faculty of Medicine, Public Health and Nursing, Universitas Gadjah Mada; Bandung Geological Museum and Sangiran Early Man Site. The research found at least 8 species of fish fossils in Java which belong to three order, i.e., the order Siluriformes with 5 identified species: Bagarius gigas, Hemibragus nemurus, Clarias macrocephalus, family Ariidae with indeterminate genus or species, Plotosus canius, Clarias batrachus, and family Pangasiidae with indeterminate genus or species; the order Perciformes with two identified species: Anabas testudineus and Sphyraena crassidens; and the order Cypriniformes with one identified species: Osteochilus vittatus. Based on the fossil findings showed that the Java Island during the Plio-Pleistocene used to be a marine environment that gradually ascending into a lowland river which closes to mangrove swamps and estuaries while the ancient Bandung lake site was a lacustrine environment with calm currents and is overgrown with riparian vegetation.

Depression is a disabling mental disorder, predicted to become the world's number 2 disability by 2020 by the World Health Organization (WHO, 2018). Chronic stress is one of the triggers for depression, causing an imbalance in brain chemicals and antioxidants levels. Although antidepressant is a common treatment, discomforting side effects has compromised its efficacy, prompting the search for alternative medicines. Chlorella vulgaris is a microalgae famous for its excellent protein and antioxidant content. In this study, C. vulgaris (360 mg/kg p.o.) potency of antidepressant in chronic unpredictable mild stress (CUMS) model of depression in female rats was evaluated compared to amitriptyline (2,25 mg/kg p.o.) for 14 days. Two types of C. vulgaris namely cultivation sourced and commercially-sold, were used. Sucrose preference test, forced swim test (FST) and open field test (OFT) were used as depression-like behaviour test to validate C. vulgaris effect. Adrenal glands were observed to further understand its effect on the stress organ. The CUMS method produced rats with depressive-like behaviour evidently by reduced body weight, sucrose preference, exploring behaviour in OFT, and increased immobility duration in FST. Furthermore, an increase in adrenal weight, fasciculata zone, and reticularis zone was observed. Both C. vulgaris significantly (p<0,05) reversed depressive-like behaviour in rats subjected to CUMS, but not the size of adrenal glands. This finding indicated both types of C. vulgaris has the potential to be an alternative antidepressant but because of the short duration of treatment, it’s speculated that C. vulgaris may not have exhibited enough difference structurally yet.

Pisang Raja is an important local banana cultivar in the economy and cultural life in Indonesia, especially at Java. There are many Pisang Raja cultivars found on Java Island with various local names in each region, resulted in problems on taxonomic identification and grouping. Conventional research for grouping banana cultivars is still using morphological characters but considered inaccurate because of its subjectivity. This study aims to analyze the genetic diversity, grouping, and genome estimation of 13 local cultivars of Pisang Raja based on molecular approach using RAPD markers (OPA primers 1-20). Clustering and Principal Coordinates Analysis were performed to the amplified products using Paleontological Statistics (PAST) application version 3.15. Results showed that there were 12 primers which successfully amplified and produced DNA polymorphic bands in Pisang Raja, specifically OPA 1, OPA 2, OPA 3, OPA 4, OPA 5, OPA 8, OPA 16, OPA 17, OPA 18, OPA 19, and OPA 20. Pisang Raja cultivars considered have high genetic diversity, indicated by high polymorphic bands (95.17%) and low similarity coefficient values (0.2-0.6). Clustering and PCo analysis resulted in 3 clusters following its genomic group consist of AAA, AAB and ABB genomes, with Pisang Raja Bali as an outgroup (ABB). However, the separation of each cluster for genome inference was unclear. Cluster 1 consists of Pisang Raja Madu (AAB) and Raja Sereh (AAB). Cluster 2 consists of AAA and AAB genomes; includes Pisang Raja Jambe (AAA), Raja Kriyak (AAA), Raja Kutuk (AAB), Raja Brentel (AAB), Raja Seribu (AAB), and Raja Lini (AAB). Cluster 3 consists of AAA and AAB genomes, includes Pisang Raja Kisto (AAA), Raja Delima (AAA), Raja Bandung (AAB) and Raja Gareng (AAB). While Pisang Monyet (AAw) and Klutuk Wulung (BBw) as wild relatives were nested in Cluster 2. There were some different results of genome estimation based on RAPD markers compared to morphological characterization, and other molecular techniques. The use of RAPD markers is quite efficient and effective for studying genetic diversity and identifying genomes in bananas.

Bromo Tengger Semeru National Park (TNBTS) which partly located in Malang, East Java, Indonesia holds various kinds of niches that can support the existence of undiscovered amphibian species. We examine a new distribution of the Leptophryne borbonica, Hourglass-toad from an area located on the slopes of the Southwest of Tengger Mountain as well as its ecological implications related to the possibility of habitat threats. The exploration was carried out on January 1st and March 1st, 2019, with the description of morphology data and collecting abiotic parameters such as temperature, humidity, altitude, and habitat preference. The distribution of the species was marked. Any important notable records of the habitat threats are documented. The results showed that the amphibians found were Leptophryne borbonica, and set as a new record on Malang, East Java. We suggested that the isolated distribution is very susceptible to ecological disturbances, future ecotourism development, and habitat destruction that prone to local extinction. Further research and conservation efforts need to be carried out for the sustainability of this species in the observation site.

Deer; Antler; Diagnostic Character; Identification; Indonesia
en
There are five species of deer (family Cervidae) living in Indonesia today. Male deer possesses antlers, a unique character of male deer. Antlers have economic values for quite a long time. Antler’s growth is influenced by several factors, therefore each species of deer have its own unique antlers’ shape and size. Antler’s identification usually relies on size measurement and overall shape of complete antlers which still attach to the skull. It is difficult to identify shed, broken or individual antler. The purpose of the research is to understand antlers’ morphological characters on each species to become diagnostic characters. Specimens analysed were collections of LIPI and were analysed with Principal Component Analysis (PCA) using PAST3 software. The results showed each species of deer having their own unique antlers’ character, and so it can be used to determine the species of Indonesian deer. The important structures for identification are relief, pedicle, brow, bez, and main beam.

en
Lake Lebo Taliwang is one of the lakes in the West Nusa Tenggara with high freshwater fish species diversity. However, the species identification of freshwater fish species from Lake Lebo Taliwang using DNA barcoding is very limited. Therefore, the objective of this study was to identify seven samples of freshwater fish species collected from Lake Lebo Taliwang based on COI mitochondrial gene as a DNA barcoding marker and establish library COI sequences of Indonesian freshwater fish. We are using a standard DNA analysis and data obtained from this study was then examined using Nucleotide BLAST and the phylogenetic tree was analyzed using the Neighbour-Joining (NJ) method with Kimura 2 Parameter (K2P) model. The results revealed that among the seven samples of freshwater fishes collected from the Lake Lebo Taliwang, three samples were identified as Anabas testudineus, the other three samples were Barbodes binotatus and one sample was Trichopodus trichopterus. The level of similarity of these freshwater fish samples referred to the database from the GenBank and BOLD was between 98-100%. The NJ tree supports the clade of each species identified in this study. This occurrence indicated that DNA barcoding by using the COI mitochondrial gene was proven to be able to identify the freshwater fish samples accurately.

There are 42 species of turtles; including sea turtle, freshwater turtle, tortoise, and softshell turtle (Reptilia: Testudines) living in Indonesia today. Turtles have economic values for quite a long time and it has led to illegal trade such as smuggling of carapace and plastron bones. Identification is needed to find out more details about the turtle species. Turtles have shells as unique features with different characteristics on each species. Shell’s identification usually relies on the shape of carapace and plastron. The purpose of this research is to understand turtle shell morphological characters and determine the diagnostic characters of each species. We conducted visual observation on specimen collections from the Laboratory of Animal Systematics, Faculty of Biology, Universitas Gadjah Mada and Museum of Biology, Faculty of Biology, Universitas Gadjah Mada. The result shows that each turtle species have their own unique shell bone’s characters, therefore it can be used to determine each turtle species of Indonesia.

Savanna, Komodo, Padar, Flores, Invasive alien plant species
en
Tropical savanna and dry forest in Indonesia are an important type of ecosystem that supports various endemic wildlife of Indonesia including savannas at Padar and Komodo Islands which is home to the Komodo (Varanus komodoensis). The Komodo dragon is considered as “Vulnerable” by the International Union for Conservation of Nature. Studies with regards to the Komodo dragons’ habitats are scarce, considering that these types of habitats are significant to support Komodo’s existence, but yet are also very prone to conversion and disturbances. This paper elaborates the results of ecological study on the tropical savanna forest in Komodo National Park as habitat for the Komodo dragon. Vegetation sampling was conducted using nested plots 20 x 20 m, 10 x 10 m, 5 x 5 m and 2 x 2 m spread across the sampling sites. Data was analysed using PRIMER software which includes cluster analysis, analysis of similarity (ANOSIM) and similarity percentage (SIMPER). As many as 17 plant species which belongs to 11 families were identified in the sampling sites. These consist of six trees habitus, six shrubs, four grasses and one palm. Asteraceae, Fabaceae and Poaceae were the plant families which has high number of species. The result of cluster analysis shows that the similarity level of the two groups (Komodo and Padar) based on the results of cluster analysis is 60%. This result infers that there are similarities in terms of species composition in savanna on Komodo and Padar Island, however, each savanna still has its own species characteristics. This is confirmed by the ANOSIM test. The ANOSIM test results show the Global R value of 0.6.With the looming challenges from invasive alien plant species (IAPS), the Komodo Island’s savanna has double threats to overcome. Hence conservation of the remaining savanna ecosystem is important

Rhacophorus margaritifer is an endemic species of arboreal frog in Java. Previous studies found this frog in several locations of Baturraden, namely in primary forest of Ketenger area, along Pancuran Pitu tourism track, and Baturraden Botanical Garden. There were still limited studies of molecular diversity of R. margaritifer and no prior data from population in the southern slope of Mount Slamet. This study aimed to look at the genetic polymorphism and determine the locus diversity of R.margaritifer population in Baturraden by using the PCR-RAPD technique. Frog tissue samples were taken from three populations in Kalipagu hiking trail (HPK 01), Baturraden hiking trail (HPK 02), and Baturraden Botanical Garden (KRB). DNA was extracted using the Chelex method. Molecular characterization was performed based on RAPD markers. The RAPD marker band pattern was changed to binary data 0-1 and analysed using Arlequin software ver.3.5. A total of 19 frog individuals were obtained during sampling at three locations. High genetic diversity had been observed in all populations with gene diversity range from 0.9643 in HPK 01 population to 1.0000 in both KRB and HPK 02 populations. A high locus variation was also observed for all populations with values of 0.159524 in KRB; 0.165816 in HPK 01; 0.192857 in HPK 02, respectively. AMOVA indicated no genetic difference among populations of R. margaritifer (p=0.50244).

Bali Botanic Garden (BBG) aspires to conduct conservation and research of eastern Indonesian plant species, including the aquatic plant species. These were important as aquatic plant species could be ecologically threatened, beneficial or even dangerous. As scientific data of BBG aquatic plant species collection was limited, we proposed this study to provide researchers and garden managers with data to conduct research, collection and maintenance of the garden aquatic plant collection. The study was carried out by sourcing list of BBG collected plant species data for its aquatic plant species. Literatures study was then carried out to gain information regarding the plant species’ heavy metal phytoremediation, conservation and invasiveness status while data analysis was conducted descriptively. The study result showed that 38 collection numbers of aquatic plant species collected in BGG were placed in five sites within the garden with 94% of all the aquatic plants collection came from Lesser Sunda Islands. Eleven aquatic plants species were listed as Least Concern by IUCN Red List. Fourteen species of collected aquatic plants were proved to possessed phytoremediation potential toward numerous heavy metal pollutants, while six species were listed as an invasive alien plant species in Indonesia. All of the provided data should be enabled the botanic garden stakeholders to come up with ideas in the research and maintenance effort of BBG aquatic plant collection.

en
Arthrospira maxima and Chlorella vulgaris contain protein, carbohydrates, antioxidants, omega-3 fatty acids, and many micronutrients. Those compounds have potency of antidiabetic and hypolipidemic activity. This study aimed to evaluate the effect of A. maxima and C. vulgaris powder administration on alteration of body weight, lipid profile, glucose levels, and visceral fat index of hyperglycemia rats. Twenty male rats were divided into 5 groups i.e. negative control (NC), hyperglycemia control (HC), metformin (M), A. maxima (AR), and C. vulgaris (CH). Body weight and visceral fat index were measured and calculated by semianalytic and analytical scales. Serum glucose levels were measured by Easy Touch GCU (Glucose, Cholesterol, Uric acid). Lipid profile levels were measured using the photometric enzymatic method. The results showed no differences in body weight between groups, except in AR group was found significantly decreased in body weight on the 20th day. Glucose serum, total cholesterol, HDL and triglyceride levels in microalgae treatment groups were not significantly different be compare to control group. LDL levels of D30 significantly different from D0, but neither between groups. The visceral fat index of a control group was higher compared to that of a microalgae group and significantly different. In conclusion, the administration of microalgae A. maxima and C. vulgaris for 30 days are effective to reduce visceral fat index but not effective to maintain body weight, glucose level, as well as not effective to improve lipid profile.

The study aimed to quantify and discuss the current condition of the tree species composition and natural regeneration of southeast parts of Bangladesh (Cox’s Bazar North Forest Division). A total of 121 stems having dbh ≥10cm and 3481 stems of regenerating tree species (dbh <10cm) per hectare were recorded. A large trees comprised of 17 species belonging to 10 families and 14 genera and 30 regenerating tree species belonging to 19 families and 27 genera have been found. The forests were highly non-uniform, with three or four species represented most of the stands. The values of diversity indices indicated limited plant diversity, which is dominated by two or three tree species. Stems of 10-30 cm dbh contributed almost 90% of the total stem density, whereas more than 80% of the total basal area still belonged to trees with dbh 100 cm or above. Dipterocarpus turbinatus was the most dominant species which have the highest Importance Value Index (IVI) with 135.82 and embodied 37.71% of the total stand density and 72.19% of total basal area. The study will provide scientific basis for the future implementation of forest conservation strategies in tropical forests of Southeast Asia, particularly in Bangladesh. This study may also pave the way to further research on regeneration potentials of the native species for conservation and enhancement of forests in future.

The petroleum fuel crisis shows that Indonesia's fossil energy reserves are limited. It is necessary to develop an environmentally, friendly and sustainable alternative energy, one of which is bioethanol. This study aims to determine the bioethanol levels of dragon fruit (Hylocereus polyrhizus) peel with the treatment of cellulase enzymes from Trichoderma reesei and Aspergillus niger. This research was an experimental study that uses steps such as making dragon fruit peel substrate and filtrate, cellulose degradation with enzymes from Trichoderma reesei and Aspergillus niger and inoculating with yeast (Saccharomyces cerevisiae) with a fermentation time of 96 hours and then measured reducing sugar levels with the method of DNS, distillation, and the measurement of bioethanol levels using alcohol meters. The results have shown that using enzymes from Trichoderma reesei and Aspergillus niger can increase the reduction of 49.68 % sugar levels in the treatment of T.reesei: A.niger (3: 1) and produce the highest bioethanol level, which is 2.46 % in the treatment of T.reesei: A.niger (2: 1)

Spodoptera litura Fab. is an insect that damage cultivated plants in Indonesia. Efforts to control it can be done by using biological agents for example by using Bacillus thuringiensis kurstaki (Btk.). Unfortunately, the Btk. is easily degraded by UV radiation. This research aimed to study the effectiveness of red and green spinach as UVB protection for Btk. and to observe the pathogenicity of Btk. formulations against armyworm. Furthermore, the sublethal effect of Btk. against S. litura was investigated. The morphology of the endospore, protein crystal, and bacterium were observed under a contrast phase microscope. The extracts at 2% (w/v) were mixed with Btk. suspensions at 5 x 104, 5x105, and 5x106 (spores/ml), respectively. The formulations then exposed under Ultraviolet B (UVB) lights for 3, 6, and 9 hours then tested against the 3rd larval instar of armyworm. The larval mortality was observed daily and the analysis of variance was analyzed by one way anova. The sublethal effects of the treatment to the pupal and adult stages were observed when the moths emerge. The results showed that the larval mortality caused by Btk. mixed with red spinach ranged from 11.7 to 26.7%. The sublethal effects of Btk. resulted in smaller sizes of pupae and imago, darker pupae, and wings abnormality of the adult stage, compared to any control treatment. The morphological observation of the bacteria showed that extracts gave UV protection against UVB. These results suggested that red and green spinach potentially can be used as a protectant for Btk. against UVB.

Nglanggeran Ancient Volcano is one of the ecotourism areas in Gunungkidul Regency, Yogyakarta. This ancient volcano is one of the geological sites in Pegunungan Sewu. Pegunungan Sewu is a National Geopark in Indonesia and has been designated as a UNESCO Global Geopark since 2015. The determination of an area into a National Geopark and Global Geopark makes the biodiversity in the area must be protected and preserved, including the plant diversity, one of which is Moraceae. The ecological and economic importance of Moraceae in Nglanggeran Ancient Volcano has not been documented properly. This fact encourages the need to do this research. The aim of this research was to record species diversity of Moraceae and its potential uses. The research was conducted in August-November 2019 at Nglanggeran Ancient Volcano and followed by data analysis in Plant Systematic Laboratory, Faculty of Biology, Universitas Gadjah Mada. The samples were collected at two different tracks, covering the track to the peak and the pathway down. There were six species found, namely Artocarpus altilis (Parkinson) Fosberg, Artocarpus heterophyllus Lam., Ficus benjamina L., Ficus septica Burm. f., Maclura cochinchinensis (Lour.) Corner, and Streblus taxoides (Roth) Kurz. The potential uses of Moraceae by local people were identified from the interview and enriched by data from literature studies indicated that Moraceae plants were used as a food, medicine, for construction, soil protection plants, and houseplant.

One alternative biofuel to substitute fossil fuels is bioethanol. Microalgae Spirulina sp. contains high carbohydrates, which has 17-25% potential to produce bioethanol. Urea and NaHCO3 can be used as additional nutrients sources of nitrogen and carbon to Spirulina sp. cultivation. Deficiency of nitrogen causing the cell’s enzymes change that shown through decreased lipid and chlorophyll synthesis. While deficiency of carbon can affect the growth rate. In this research, the growth rate of Spirulina sp. is analyzed using Optical Density (OD) method. The growth rate calculation is used to measure the growth of microalgae cells shown in the growth curve. This was a laboratory-scale method using CRD with 4 treatments and 5 replications namely treatment A addition of 0.36 g/500 ml urea without addition of NaHCO3, treatment B addition of 0.043 g/500 ml NaHCO3 without addition of urea, treatment C addition of 0.36 g/500 ml urea and 0.043 g/500 ml NaHCO3, and control without addition of urea or NaHCO3. The results indicated that addition of urea and NaHCO3 didn’t affect to OD and Spirulina sp. growth rate. The highest growth rate was treatment A with 0.00906/day of growth rate followed by treatment C which has 0.00865/day of growth rate. Treatment B and control treatment (K) showed a low growth rate. The maximum OD value obtained in treatment C was 0.674 cells/ml on the 10th day. This research can be used as the reference to larger scale of Spirulina sp. cultivation in the field of bioethanol production.

This study aimed to detect and evaluate the genetic mutation from mutagenized soybean by RAPD markers. Soybean seeds of “Grobogan” variety were treated with two different concentrations of EMS (0.5% and 1%) and three incubation times (4, 6 and 8 h). DNA whole-genome was isolated from young leaf seedling with the Qiagen DNeasy Plant Mini Kit. Twenty OPA primers (OPA-1 to OPA-20) were used for DNA amplification. The results showed that EMS treatments successfully generated genetic variation in soybean, which indicated by high values of PIC, EMR, and MI. RAPD primers that effective to detect the mutation were OPA-2, OPA-07, OPA-10, OPA-11, OPA-12, OPA-13, OPA-14, OPA-15, OPA-16, OPA-18 and OPA-20. The band expression of those primers was exhibited a stronger intensity along with increasing of EMS concentration and incubation time used in this study. Treatment of 0.5% EMS in 6 hours incubation was successfully generated soybean mutants with the lowest genetic similarity compared to the wild-type. Thus, this study provides a new approach to generate genetic variability in soybean and has the potential to improve for soybean breeding program.

The haploid or double haploid plant of eggplants could be produced from microspore culture (embryogenesis of microspores). In the breeding programs, microspore can be developed into an embryo directly after exposure to stress treatment during cultured. Stress (temperature and starvation medium) is an important factor in the induction of embryogenesis microspore. This study aims to induced embryogenic microspores from eggplant CV. Gelatik. The stage late-uninucleate microspore (Vacuolate Microspore/VM) and early binucleate (Young Bicellular Pollen/YBP) are the suitable stages to induce multinucleate structure. There are 3 methods used in this research; 1) Determination of the stage development of microspore based on flower buds length and anther length. 2) Induction of embryogenic microspore on the pre-treatment and starvation medium. 3) After giving pre-treatment for 4 days, micropores were transferred to culture medium A2 at 28oC in dark conditions to induce the multicellular structures. This study reported that 50-68.51% of the VM+YBP stage obtained in the range of flower bud lengths of 10-17 mm, and 5.0-6.9 mm, the range of anther length containing VM+YBP of 50-77.48%. The pre-treatment heat shock at 33oC in the medium B for 2 days, produced embryogenic microspores with a high percentage, that is about 50.19%, while microspores at 25oC and 4oC respectively 46.17% and 49.28%. Pre-treatment for 4 days at 4 oC, 25 oC, and 33oC with the percentage of embryogenic microspores apiece 32.87%, 27.45%, and 37.34%. The multicellular (starlike) structure begins forming on the fifth day of incubation in culture medium (A2) after pre-treatment in B medium at 33oC.

This study was conducted to determine the prevalence of ectoparasite infestation among stray cats around Surabaya traditional markets. A total of 305 stray cats were collected around 17 traditional markets in Surabaya City and were examined for the presence of fleas with a fine-toothed flea comb. Surveys were conducted during May-June 2019. 228 of 305 stray cats (74.75%) were infested with one species of ectoparasite. The average number of C. felis in every cat was 2.54, while the number of F. subrostratus in every cat was 0.33. Additional data about the gender, pregnancy/maternity, and bodyweight of every cat were recorded. The result of chi-square test shows that there is a significant difference between gender, pregnancy status, and bodyweight by the occurrence of ectoparasites (p=0.008; p=0.00; p=0.00). A total of 878 ectoparasites consisting of flea and lices, namely Ctenocephalides felis (88.27%) as the dominant ectoparasite, followed by Felicola subrostratus (11.73%). The highest infection rate (prevalence) of ectoparasite was found in Pucang Market (16.81%), while the lowest prevalence was found in Mulyorejo Market (0.8%). Coinfection was observed in only a few cats (1.63%). Multiple Regression showed that pregnancy is the most influential factor in the occurrence of fleas (p=0.000). These results should be taken into account among health workers to prevent a possible outbreak of zoonotic diseases caused by fleas.

This research aims to identify physicochemical characteristics in natural breeding habitats/ phytotelmata of dengue vector—including Aedes (Stegomyia) aegypti and Aedes (Stegomyia) albopictus. The research was conducted during rainy season and pre-dry season (from January to June 2017) in the region with the high cases of Dengue Hemorrhagic Fever (DHF). The entomological survey was carried out by stratified random sampling in urban and rural areas in order to find potential breeding habitats, every natural breeding habitats in sampling location were checked for the presence of Aedes larvae. Physicochemical characters that consist of temperature, turbidity, carbon dioxide, ammonia, nitrate, sulphate, pH and dissolved oxygen were recorded. Larval species were taken and then identifying activities were conducted in the Laboratory of Entomology. Data were analysed using the Chi-square test. Results showed that only dissolved oxygen that significantly associated with larval abundance (p=0.039). while others are not significantly associated. Whereas, other characters are associated with each other, carbon dioxide associated with the ammonia and sulphate (p=0.001; p=0.028). Turbidity associated with the dissolved oxygen (p=0.022) and pH associated with nitrate (p=0.001).

Bawean Island is a small island located between two islands (Java and Borneo). Geographically, the diversity of plants, especially epiphytic plants on this island is very interesting to be studied. This research aims to investigate the diversity of epiphytic plants, focussing on epiphytic orchids, Hoya and Dischidia in Bawean Island Nature Reserve and Wildlife Reserve. It was conducted through an inventory of epiphytic orchids and hoya growing on host trees. The results showed there were 10 species of epiphytic orchid and 3 species of epiphytic Hoya, and 1 species of Dischidia growing on-location studies. The epiphytic orchids which found in location studies included Phalaenopsis amabilis, Aerides odorata, Cymbidium aloifolium, Dendrobium anosmum, Rhynchostylis retusa, Liparis condylobulbon, Taeniophyllum biocellatum, Cymbidium sp., Eria sp. Orchid species that most often found in the study location was Phalaenopsis amabilis. In addition, this study recorded Taeniophyllum biocellatum as an endemic orchid from Java that was found on this island. The epiphytic Hoya recorded in there, i.e. Hoya diversifolia, H. verticillata, and H. amoena, and also only found 1 species of Dischidia was Dischidia imbricata. There were 12 species of trees as the host trees of epiphytic, i.e. Irvingia malayana, Tectona grandis, Diospyros buxyfolius were the host trees frequently found as the host of the epiphytic plant. Zone 3 as an area of 1/3 basal part of a total length of the branches was the most preferred zone by epiphytic orchids and hoya. The epiphytic orchid and hoya hardly found in Zone 5.

Alas Purwo National Park (APNP) is a conservation area with lowland forest type. The adaptation of plants conserved is strongly influenced by environmental factors and the behaviour of flowering and fruiting. The aims of this research were to find the number, species, dominance, and abundance of flowering and fruiting plants, comparison of flowering and fruiting species, and environmental factors affecting the flowering and fruiting time in APNP observation tracks. This study used purposive random sampling in each observation track where flowering and fruiting plants were found. Environmental factors (temperature, humidity, light intensity, soil pH, elevation, and coordinates) in each observation track were measured. Data analysis was conducted using Microsoft Excel and PAST 4.0. statistic program. The behaviour of flowering and fruiting plants species in APNP was unique. There were 90 species of flowering and fruiting plants in APNP from 45 families. Most species often found flowering and fruiting were Orophea enneandra, Polyalthia littoralis and Leea angulata which were scattered in Moto Lele, Patirtan Mas, and Sadengan Savanna. Fruiting plants species were more often found than flowering ones. Temperature and light intensity became the two most affecting environmental factors on flowering and fruiting plants behaviour. The study of flowering and fruiting behaviour is very important for genetic resources conservation and conservation areas management.

Nyabah, or Jabah (Pinanga arinasae J.R.Witono) is pinanga or palm which is endemic to Bali. This study aimed to determine the distribution, abundance patterns, and habitat preferences of P. arinasae, and also its natural microclimate on Mount Pengelengan, Bali, on which the species occurred. Field observations were conducted using systematic sampling method. 20 x 20 m plots were made along a transect of forest path on the right and the left, with 100 m distance between plots. Results showed P. arinasae distribution in Mount Pengelengan grows clumped with different abundance in each plot. Microclimate observations (light intensity, humidity relative, and air temperature) each plot varies the effect on the distribution and abundance of P. arinasae. Light intensity is the main factor that regulates the abundance and distribution of P. arinasae and this species has the most abundant on the limited canopy cover area which has high the light intensity at 1319 lux. Autecological data is the first step in conservation efforts.Retraction Note. On 16 October 2020, the editorial team were made aware that similar dataset of this article had been published in Chapter III “Vegetation Ecology of Bedugul” page 29-53 of a book titled “Ecology of Bedugul Basin Bali” (ISBN: 978-979-8275-55-5), published by Seameo Biotrop in 2018. An investigation was held and side-by-side comparison showed that this article has 35.6% similarity with the book chapter including the data tables and several paragraphs of text. It is clear this article is a duplicate publication which is categorized as publication misconduct. Hence, this article is retracted and the authors are notified.

Dengue Hemorrhagic Fever (DHF) is caused by Dengue Virus and transmitted by female Aedes mosquito which spread almost all over the world. Aedes sp. mosquito lives cosmopolitan and breeds in wet environments. Panggungharjo and Bangunharjo villages were categorized as endemic and non-endemic DHF areas, respectively. The aims of this research were to study the characteristics of Aedes sp. mosquito breeding sites, the identity of presence species found in the sites, and the resistance status of Aedes sp. mosquitoes against organophosphate insecticide. The method was using a larval survey which consists of 200 houses as respondents located in Panggungharjo and Bangunharjo villages. The larval resistance was tested by a biochemical method since resistance could be associated with esterase enzyme activity. The characteristics of mosquito breeding sites that found were open containers, filled with clear and calm water, dark and rough wall surfaces, the bottom surface was not directly in contact with the ground, the water temperature was 27-29 °C, pH 6.5-7, and not directly exposed to sunlight. There was only one species of mosquito was found, Aedes aegypti. The resistance test of Aedes sp. larvae showed that Aedes sp. larvae population from Panggungharjo village were susceptible, and Aedes sp. larvae from Bangunharjo village were in moderate resistant against organophosphate insecticide.

Penge Pakraman village is a traditional village that has the potency to become ecotourism. The emergence of new tourist attractions affects land changes to support tourism activities. This causes the number of plant species in nature to decrease. Plant conservation by utilizing local wisdom is one effort to reduce the decrease of plant species number. The application of Tri Hita Karana and Tri Mandala in Balinese daily life able to support plant conservation activity. The objective of this research was to determine the role of Tri Mandala concept in plant conservation at Pakraman Penge home garden. Data collection methods are carried out through observation plant location with inventory number and name of plants in house sample. Plant use continues with study literature. The results of an inventory of plant diversity in home gardens of Pakraman Penge village recorded 70 species of plants from 16 houses sample. The plant habitus varied from herbs, shrubs until trees. Plant species in the home gardens have functions for ceremonies (51%), medicinal (24%), ornamental (17%), food (6%), and spices (2%). However, based on the location, most plant species were found in madya mandala and the lowest were found in utama mandala. We also found plants with conservation status consist of least concerned (15 species), vulnerable (Dracaena draco), near threatened (Cycas rumphii), endangered (Coffea arabica). Therefore, the application of Tri Mandala concept on Balinese home gardens supports plant conservation and gives economic benefit in individual level

Microalgae appeared to be an alternative feedstock for renewable biodiesel production due to their capability to accumulate considerable amounts of lipids. In this study, mutagenesis using UVC light with different periods was applied to Chlorella sp. 042 to produce a microalgae strain with high lipid productivity of 45, 60, and 75 min. The Nile red fluorescence method was conducted to select a Chlorella sp. mutant with high neutral lipid and generated one mutant from every UV mutation period, M45-06, M60-02, and M75-21. All of the mutants have higher growth rates than the wild type. Chlorella sp. 042 M60-02 achieved the highest lipid productivity, with 34 mg L-1 day-1. Furthermore, as other major biochemical components, carbohydrate and protein contents were determined. Our results showed that all the mutants enhance their carbohydrate and protein contents compared to the wild type. However, mutations for more than 60 min do not intensely change the protein content of mutant microalgae. Gas chromatography-mass spectrophotometry analysis revealed that M60-02 mutant has similar FAME profiles with the wild type, which contain palmitic acid (C16:0), stearic acid (C 18:0), oleic acid (C18:1), and linoleic acid (C18:2). These results demonstrate that the UV mutation of Chlorella sp. 042 for 60 min is suitable as a source of biodiesel production.

One factor affecting the survival of a species in a tropical ecosystem is its ability to respond to environmental conditions, which depend on their ecophysiological performances. Plants ability to transport water as a major environmental factor would determine their survival. The anatomy of xylem inside leaves and stem as water conductive tissue will dictate the rate of water transport through the plant stem and leaves. Leaf vein, which contains xylem vessels, dictates water transport through leaves and plant’s ability to control water loss through stomata. This research found that tree saplings composing a lower canopy of tropical forests have different ecophysiological attributes. Pioneer species, such as Cinnamomum sp., Diospyros macrophylla, Castanopsis costata, Elateriospermum tapos, and Ziziphus sp., have higher leaf vein density than primary species, such as a member of genus Garcinia, Shorea, Dipterocarpus, and Syzigium. It implies that pioneer species might have higher rates of water transport and consequently, higher rates of photosynthesis. If forest vegetation was more opened, then pioneer species may dominate the area as they are more tolerant of light. The Composition of forest vegetation with different ecophysiological characteristics may affect the forest dynamics and hydrological cycle.

Excessive consumption of fatty foods can lead to hyperlipidemia, which is often coupled with hypertriglyceridemia (HTG), a condition where blood plasma triglyceride (TG) levels elevated beyond normal levels. This condition may disturb physiological functions of the body, such as reproductive functions, and other physiological imbalances leading to chronic stress and depression. Ulva lactuca is a potential natural treatment for HTG, as it contains various nutrients to aid physiological functions. This seaweed also has high levels of Cd, which can increase depression. Therefore, research on the potential benefits of U. lactuca should be followed by an investigation of its health risks. This research aimed to examine the effects of HTG and treatment with U. lactuca on reproduction and depressive-like behavior of male Wistar rats (Rattus norvegicus Berkenhout, 1769). The data collected in this research include body weight, serum TG concentration, gonadosomatic index (GSI), serum testosterone concentration using competitive ELISA, and depressive-like behaviors assessed using the Forced Swim Test (FST) and Open Field Test (OFT). Data were analyzed using One-Way ANOVA followed by DMRT, independent- and paired-samples t-test, and Kruskal-Wallis H test with a significance value of α=0.05. Body weight, serum TG and testosterone concentration, GSI, and depressive-like behaviors were increased by the HTG condition. Ulva lactuca at the1500 mg/kg BW/day did not significantly affect body weight, testosterone concentration, and depressive-like behaviors of HTG rats. Meanwhile, this treatment significantly increased the GSI and depressive-like behaviors of healthy rats. These results suggest that Ulva lactuca treatment not only enhances gonad growth and development but also increases depressive-like behaviors.

Avifauna inhabiting the mountainous forest ecosystem is severely threatened by anthropogenic disturbances, especially in the Java island of Indonesia. Yet, efforts to monitor the avifauna diversity are lacking, including in one of the mountainous forest areas, Universitas Brawijaya Forest (UBF). In this study, information about diversity, community structure, feeding specialization, and conservation status of avifauna is presented. Observations were conducted from December 2019 to February 2020 on two designated tracks with different degree of disturbances. Data were analyzed based on their conservation status, local distribution, feeding specialization (Jaccard similarity index), species richness, total abundance, species diversity (Shannon-Wiener diversity index), and importance value index (IVI). A total of 51 species from 27 families were identified. Two species at risk (one Near Threatened and one Endangered) and 9 protected avifauna were noted. This study can be used as the baseline data for future conservation management in the UBF.

The distribution of a species can help guide the protection activities in their natural habitat. Conversely, the lack of information on this distribution makes the protection strategy of this species difficult. The research was conducted in Way Canguk Research Station, Bukit Barisan Selatan National Park from January until March 2018. The purposes of this research were to create a distribution prediction map of Sunda pangolin (Manis javanica) and estimating the environment variables that most influenced the probability of the distribution. Fourteen points of camera trap coordinates were used for presence data with nine types of environment variables such as elevation, slope, understorey, canopy cover, distance from roads, distance from rivers, distance from villages, food source, and distance from the threat. The result of maxent showed an Area Under the Curve (AUC) value of 0.909 categorized as very good. The highest probability of Sunda pangolin distributions was in the Pemerihan Resort and Way Haru Resort area, while the dominant environmental variables included the distance from the village, the canopy cover, and the distance from threat with the value 47.7; 25.85; and 15.8%, respectively. Prediction maps and environment variables can help to identify the population of Sunda pangolin in the wild and can provide input for the national parks to prioritize protection areas for Sunda pangolin from the increased poaching.

Lichen of the genus Usnea is quite common being used as a traditional herbal remedy. This genus is characterized by thallus, which is very similar among the species, leads to some difficulties in distinguishing them. In Indonesia, such research report on the availability of this genus based on their morphological characteristic is minimal. This might be due to too high morphological similarities among them. The molecular character, which is based on the DNA Barcode of Internal Transcribed Spacer (ITS) rDNA sequences, with its conserved region (5.8S) and varied region (ITS1 and ITS2), are becoming essential characters on identifying as well as analyzing the phylogenetic. The current study then proposed to identify and draw the species dendrogram of species within the Usnea genus obtained from Mount Lawu Forest of Central Java and Turgo Forest of Yogyakarta based on their phylogenetic and phenetic analysis. The dendrogram was constructed with UPGMA using the simple matching coefficient, whereas the phylogenetic tree was constructed with Maximum Likelihood (ML) using Kimura-2 parameter with 1000 bootstrap. The data were unable to draw phenetic relationships among the subgenus Usnea and Eumitria members. The phylogenetic tree shows the primary two clades, distinguishing the subgenus Usnea and Eumitria. The ITS rDNA sequence was able to identify most of the Usnea species.

Phalaenopsis amabilis (L.) Blume orchid is an Indonesian national flower. The number of these orchids in their natural habitat is very limited, therefore plant propagation efforts are needed. One of the promising methods is plant propagation by inserting embryo gene AtRKD4 from a model plant Arabidopsis thaliana into the orchid genome to produce many somatic embryos. From previous research, we have obtained 28 plant P. amabilis transformants carrying the AtRKD4 gene, however, it was unknown whether these plants have normal phenotypes and growth similar to their parents. Therefore, descriptions on growth and morphology are needed. This research aimed to evaluate the phenotype of P. amabilis carrying 35S::AtRKD4 the transformants grown in greenhouse. To achieve it, AtRKD4 gene integration stability on transformants genome was analyzed. Morphology and cross-section anatomy structure on transformant and non-transformant plantswere described. The stability of AtRKD4 gene integration in the plant genome was confirmed by amplification of the AtRKD4 gene from genomic DNA with Polymerase Chain Reaction (PCR) using a specific primer for AtRKD4 and ACTIN genes as the internal control. The quantitative data from morphology and anatomy measurements were analyzed statistically using ANOVA. The results showed that AtRKD4 was stably integrated into the genome of P. amabilis transformants and all transformant plants showed similar morphology and anatomy characteristics as non-transformant plants. The AtRKD4 embryo gene was stably integrated into the orchid genome and the transformant plants grow normally without significant changes in phenotype.

Borobudur Temple is a historical heritage building located in an open area and made of porous building materials (stone materials). This condition makes the Borobudur Temple susceptible to various problems related to degradation and weathering. Biodeterioration of Borobudur Temple may be caused by activities of living organisms present in the biofilm of stone. Continuous monitoring and evaluation need to be carried out by observing and isolating the growth of micro-organisms, including epilithic microalgae. Therefore, this study aims to isolate and identify epilithic microalgae from the biofilm on Borobudur Temple stones. Epilithic microalgae were isolated to obtain a uni-algae and maintained under culture conditions. The morphological of microalgae were observed using light microscopy, while the 18S rRNA gene sequence determined the molecular identification of microalgae for eukaryotic and 16S rRNA sequence for prokaryotic. A total of nine epilithic microalgae were successfully isolated from the biofilm of Borobudur Temple stones. The isolated were identified as Ankistrodesmus falcatus, Tetraselmis cordiformis, Pseudendoclonium arthropyreniae, Anabaena cylindrica, Nostoc gelatinosum, Oscillatoria limnetica, Messastrum gracile, Stigeoclonium aestivale, and Scenedesmus acuminatus. This is the first study for the identification of microalgae from Borobudur temple stones. The isolates will be collected and will be used as a source for further study.

Eaglewood is Indonesia’s important trade commodity in the form of resins from several infected species of Thymelaeaceae. The basis to determine its international trade quota through CITES is derived from the estimated eaglewood-producing species grown in their habitat. This paper aims to estimate the biomass of eaglewood, Aquilaria filaria, in the karst ecosystem of West Papua. We conducted a plot-based method and calculated the biomass of A. filaria using a diameter-based allometric equation and simulated using a bootstrap procedure. The results showed that 15,500 tons of naturally infected eaglewood are estimated in the karst ecosystem of West Papua.

Updated data is an essential requirement for carrying out research, planning, and policy briefs. The Coral reef triangle region is one of the areas with the highest diversity of marine biota and the discovery of new species in this area are increasing every year, much of this information is already available. However, most of the data is not available per region and is still scattered. This study aims to create a checklist and assessment of new species and a new record of fishes from this region over the last ten years based on several aspects, including species composition, pattern of distribution, endemicity, and depth using every source of the report and secondary literature data. The current new species and a new record of fish in the last decades combined consists of 360 species (268 new species and 92 new records). The most speciose group of family dominated by Gobiidae (93), followed by Labridae, Pomacentridae and Serranidae (18), Apogonidae (17), Dasyatidae (15), and the rest were ranged from 1-9 species per family. More than half of new species and new records are found in Indonesia, followed by the Philippines, Papua New Guinea, and Solomon Island. The result shows that cryptobenthic Families especially Gobiidae from genus Trimma and eviota are dominated the trend of new species and new record discovery and it is expected to rise over time while there will also be an emergence of some possibly new endemic species from major and rare families from the eastern part of Indonesia (West Papua and Papua New Guinea). Thus, the eastern part of Indonesia (Papua, Maluku, Aru Sea, and Papua New Guinea) and the northern part of Indonesia (North Sulawesi and Philippine) are suitable for exploration for marine biodiversity discovery research in the future.

Elephantopus scaber L. is a plant that has potential as traditional medicine. Callus induction and production of secondary metabolite content can be increased by culture callus using plant growth regulators. This study was purposed to investigate the effect of IBA and kinetin concentration on the induction and secondary metabolite profile of callus from E. scaber L. leaves. Leaves explant of E. scaber L. were cultured on MS medium with various combination concentrations of IBA and kinetin for 6 weeks and then callus was extracted using methanol. Secondary metabolite content from the resulting extract was analyzed using the phytochemical screening method. The result showed that the treatment of IBA 2.0 mg/L and kinetin 1.0 mg/L and treatment of IBA 2.0 mg/L and kinetin 2.5 mg/L are the fastest combination concentration to induce callus at 5.33 ± 0.577 days. Treatment of IBA 2.0 mg/L and kinetin 2.5 mg/L produced callus with the highest fresh weight and dry weight at 0.7016 ± 0.0588 grams and 0.0766 ± 0.0062 grams, respectively. The morphology of calluses grown during this study was compact with various colors appearance, such as light green, brownish green, and brown. Secondary metabolite content of methanol extract of callus E. scaber L. are flavonoids, alkaloids, terpenoids, and saponins.

Several bacteria were isolated from straw mushroom (Volvariella volvacea) cultivation medium. There are three potential isolates previously characterized and has growth inhibition effect against V. volvacea. This screening result lead to the further study about the inhibition activity against phytopathogenic fungi. The aim of this research is to investigate the antifungal activity of three bacterial isolates against three phytopathogenic fungi and identification of the bacteria. The method used in this study are antifungal assay using co-culture method and disk difussion assay using the filtrate of each bacteria. The profile of antifungal compound was identified using ethyl acetate extract followed by evaporation and gas chromatography (GC-MS) analysis. Identification of each isolates was performed using 16S rDNA amplification and sequencing. Three phytopathogenic fungi i.e Cercospora lactucae (InaCC F168), Colletotrichum gloeosporides (InaCC F304) and Fusarium oxysporum f.sp. cubense (F817) were co-cultured with bacterial isolates C2.2, C3.8, and D3.3. The C3.8 isolate has highest average inhibition activity either using isolate and filtrate. The result relatively consistent against three phytopathogenic fungi. The metabolite profile of C3.8 isolate showed the Bis(2-ethylhexyl) phthalate as the main compound with 97% similarity. Bis(2-ethylhexyl) phthalate has potential effect as antibacterial and antifungal compound. According to EzBioCloud and GeneBank databases, the C2.2 isolate identified as Bacillus tequilensis, C3.8 as Bacillus siamensis and D3.3 as Bacillus subtilis subsp. Subtilis. This study also shows the potential of Bacillus siamensis C3.8 as biocontrol against phytopathogenic fungi.

Orchid is one of the most popular ornamental plants in the world. One of the orchid genera that is collected in a large number and known to have high morphological variations in the Liwa Botanical Garden is Dendrobium. However, to date, many Dendrobium collections have not been identified. Given the urgency of identification and the limitations of specimens in the field, especially flower organs, this study is important. This study aims to determine variations in morphological characters, phenetic relationships, and to identify Dendrobium collections based on leaf morphological characters in the Liwa Botanical Garden. Five accessions of Dendrobium were collected, namely CAT140, CAT 144, CAT 271, CAT 274, and IR015. Observation of 11 morphological characters leaves showed that leaf had high variations. The phenetic relationship based on the Gower similarity value and the UPGMA method shows that the Dendrobium in the Liwa Botanical Garden can be classified into 2 main groups formed with a similarity index value of 0.813. Based on Principle Component analysis values, it is known that the characters that have a large influence on grouping are the ratio of leaf length and width, leaf cross section, and leaf arrangement. The phenetic dendrogram topology is supported by the morphological character classification. The results of this study are expected to be basic information in the identification of natural orchids and conservation efforts in the Liwa Botanical Garden.

This research aimed to study the types and abundance of fish which was found in branched and table coral habitat. The quadrate transect method was used at the location of the habitat of branched and table corals. The observation was carried out for 3 days. It was conducted 3 times/day, in the morning, the afternoon, and the evening with ± 10 minutes of observation time for each observation. The method used was transect quadrat 5 m x 5 m with direct observation techniques by means of snorkeling. The types and numbers of individual fish were recorded using the visual census method. Snorkeling was done straightforwardly and looking around by following the contour of the reef. In branching coral habitat, 11 species of fish were found with a total of 66 individuals. On the other hand, on the tabulate reef habitat, there were 9 species of fish with a total of 50 individuals. Both habitats have different types of fish. In the branched coral habitats there were more individual than in the table reef habitats. Fish species found in branched coral habitat and table type fish habitat were different. In branched coral habitats were found more reef fish species than in table coral habitats. These results illustrated that the condition of the coral reefs at Tanjung Beach is still in good condition.

Barred mudskipper (Periophthalmus argentilineatus) has a potency to be developed as protein for human consumption and ornamental fish. The fish also has an important role in mangrove ecosystems. Nevertheless, many barred mudskippers have been considered a cryptic species. Therefore, accurate identification is needed to clarify species identification of the barred mudskipper using DNA barcoding. This research aimed to identify barred mudskippers from Tekolok Estuary (East Lombok, West Nusa Tenggara, Indonesia) using COI mitochondrial gene as a DNA barcode and analyze genetic relationship with other barred mudskippers from several regions of Indonesia recorded in GenBank. This study used a PCR method with universal primers FishF2 and FishR2. The data was then analysed using DNASTAR, BLAST, Mesquite, MEGA, DnaSP, BEAST, GenAlEx, and NETWORK. The results revealed that barred mudskipper from Tekolok Estuary has been verified as Periophthalmus argentilineatus. The results also exhibited that P. argentilineatus from Tekolok Estuary has a close genetic relationship to P.argentilineatus from Tukad Bilukpoh (Jembrana, Bali). In addition, phylogenetic analysis showed that P.argentilineatus from Indonesia consisted of two clades with a genetic distance of approximately 6.64%. This analysis revealed evidence of the cryptic diversity of P.argentilineatus from Indonesia. Further detailed studies are needed to clarify whether Indonesian P.argentilineatus should be categorized into more than one species or single species with several subspecies.

This study aimed to determine the sex of Tanimbar Cockatoo (Cacatua goffiniana) birds by amplifying Chromodomain Helicase DNA-binding-1 (CHD-1) gene on Z and W sex chromosomes as well as to compare the quality of DNA extraction and PCR amplification products from samples derived from peripheral blood and plucked feathers. This work used five C. goffiniana birds which were collected from the Wildlife Rescue Center (WRC) in Pengasih, Kulon Progo, Yogyakarta. From each C. goffiniana, feather samples were collected by plucking feathers on the ventral wing and peripheral blood samples were taken by cutting their nails and collecting the blood into microhematocrit tubes containing heparin. The next stage was DNA extraction and DNA amplification on the CHD-1 gene using the PCR method by NP, P2, and MP primer pairs. Then, products of DNA extraction and PCR amplification were electrophoresed on 1.5% agarose gel and visualized under a UV light transilluminator with a wavelength of 260 nm. The visualization showed that samples from peripheral blood generated clearer DNA fragments compared to plucked feathers. Two of the five samples were male C. goffiniana and the other three samples were females. In the male Tanimbar Cockatoo was amplified a single DNA fragment of the Z sex chromosome in size of 300 bp, whereas in the female C. goffiniana was amplified double DNA fragments of Z and W sex chromosomes in size of 300 bp and 400 bp respectively. The DNA quality showed that the DNA quality from peripheral blood samples were better in quality than the DNA collected from plucked feather samples.

Biodiversity plant (new source) in Food Nutrition for Stunting Children
Article review (source data from internet)
en
Stunting is a global health problem. Based on WHO data, there are 161 million children who experience stunting. Breastmilk supplementation in the form of Moringa oleifera leaves powder is known to be beneficial in suppressing the stunting incidence. Moringa oleifera leaves powder contains protein, micronutrients, and minerals such as calcium, iron, sodium, vitamins C and E, beta carotene, and antioxidants (flavonoid acids, phenolic acids, glucosinolates, isothiocyanates, and saponins). The use of Moringa oleifera leaves powder in stunting cases has been carried out, but further studies in the aspects of nutrigenomics and molecular biology have not been conducted. This study is a literature review of relevant articles from www.pubmed.com, www.sciencedirect.com, and scholar.google.com. The author used keywords "stunting", "nutrigenomics", "biomolecular", and "Moringa oleifera". Pathogenic microbe such as Shigella and pathogenic E. coli ingestion can cause changes in DNA sequences in the stunting pathogenesis. Moringa oleifera leave powder can pass through nutrigenomic and biomolecular mechanisms. Some macro and micromolecules of Moringa oleifera leaves powder such as folate plays a role in DNA methylation; vegetable protein and fatty acids act as promoters in DNA sequences; vitamins act as cofactors for enzymes, antioxidant, and antiinflammation. Seeing various potential mechanisms in the aspects of nutrigenomic and molecular biology, Moringa oleifera leaves powder can be used in overcoming stunting. Further research is needed to give more review about cytokines and molecules included in this literature review.

Sibling indices can be used as a comparison through alleles Short Tandem Repeats [STR] loci. This is an observational study among Maduranese with 4 STR loci (CSF1PO, THOI, TPOX, vWA) obtained from their blood samples. The percentage of alleles shared: 82.5% [33 times] with 2 allele sharing, 12.5% [5 times] with 1 allele sharing, and 5 % [2 times] with 0 sharing alleles. Sibling indices (SI) calculation results: 65% of sibling indices pairs have SI greater than 100 and 15% of them were between 10-100 (strong and very strong). Sibling indices interpretation is supported; therefore, the claimed sibling indices relationships were indeed true among Maduranese ethnic group in Surabaya.

This research aimed to identify the indigenous Mushroom Growth Promoting Bacteria (MGPB) bacteria that can increase the growth of Volvariella volvacea. The research began by isolating indigenous MGPB from planting media of straw mushrooms in Karawang, Indonesia. The screening was performed to select bacterial isolates that can promote the highest growth of mushrooms by dual culture method on PDA media. There were 10 of the 58 highest bacterial isolates that have a positive effect on the vegetative growth of mushrooms. The 23K bacterial isolate was the most significant increase in mycelium growth compared to other isolates and bacteria-induced controls. A bacterial isolate 25K by gene analysis was identified by 16S rRNA (518F primer (5’- CCA-GCA-GCC-GCG-GTA-ATA-CG -3’) and 800R primer (5’- TAC-CAG-GGT-ATC-TAA-TCC -3’). The result from gene analysis shows that there are ~1550 base pairs products. BLAST analysis and phylogenetic tree adjustment results show that the closest diversity of this bacterial isolate 25K is Bacillus thuringiensis serovar konkukian str. 92-27 (equality value = 99%).

Indonesia is a tropical country that has natural forests and is suitable for orchid species habitat, leading to more than 5,000 species of orchids grow. The tropical area is the main distribution centre for epiphytic orchids, one of which is Dendrobium, which grows more than 1,000 species throughout the world. Orchid seeds are very small and do not have an endosperm, making germination difficult in their natural habitat. Mycorrhizal association with orchids plays a role in the survival of orchids in nature through seed germination and growth. This study aims to provide a deeper understanding about the important role of mycorrhiza in seed germination and growth of Dendrobium. The mechanism of mycorrhizal association with orchids begins with the initial contact of the fungus with the orchid, hyphae enter the cortex cells to form peloton, peloton lysis, and exchange of nutrients occurs. Orchid mycorrhiza that mostly found groups in Dendrobium are Rhizoctonia (Epulorhiza, Tulasnella, Rhizoctonia). Mycorrhiza plays a role in increased secretion of phytohormone and enzyme activity which supports seed germination and growth of orchids. Specific mycorrhizal data on orchids can be used as an effort for in-situ and ex-situ conservation of Indonesian orchids, including Dendrobium.

This research was conducted to observe the body weight gain and carcass quality of the hybrid chicken derived from the crossing between female F1 Kampung Super and male F1 Kampung-Broiler. The weekly weight gain for seven weeks and carcass quality, including breast yield, protein content, lipid content, moisture, and pH were measured with each group consists of six individuals. The chickens were slaughtered for meat quality measurements on the 7th week. The results showed that the hybrid chickens’ weight at the 7th week (888.22±139.63) was higher than layer (467.06±85.7) and pelung (436.39±42.33). The hybrid chicken’s breast yield (3.20%) was significantly higher than pelung’s (1.66%). These characteristics of hybrid chicken breast muscle lead to the conclusion that hybrid chicken is a potential alternative meat-type chicken with local chicken meat characteristics and has relatively fast growth.
