Rapid urban population growth has driven extensive economic, residential, educational, and cultural development, leading to the conversion of green spaces into built-up areas. This conversion interferes with the regulations of air temperature and Thermal Humidity Index (THI). This research investigated the characteristics of green open spaces at Denggung Park and Gadjah Mada University Wisdom Park, examining their effects on microclimate conditions and the relationship between green space conditions and THI levels. The methods included a literature review, field measurements of vegetation and microclimate variables, tree crown profile analysis using Sexl-FS, and Spearman Rank Correlation. Results showed that tree density has a direct relationship with THI. The private green space (Wisdom Park), with 126.33 trees/ha, achieved superior THI compared to the public space (Denggung Park), with 49.01 trees/ha. The Gadjah Mada University Wisdom Park's more complex canopy structure and optimal canopy connectivity significantly enhanced THI. Spearman Rank Correlation analysis revealed strong relationships between the tree density and thermal comfort level for Denggung Park (-0.52) and for Gadjah Mada University Wisdom Park (-0.69), with a p-value < 0.05. These findings confirm the critical importance of optimizing vegetation structure and density to support thermally comfortable urban environments.

The Dayak Kuhin community, native to Central Kalimantan Province, had a traditional agricultural culture called nugal, which was carried out once a year. Nugal was considered an agricultural culture that involved opening fields in the forest, but it was often associated with causing forest fires. To clarify the realities of the practice, this research aimed to explore the nugal process and associated forest conservation efforts by taking a case study of the Sapundu Hantu Village, Seruyan Hulu District, Seruyan Regency, Central Kalimantan Province. This research employed an ethnographic method and a thick description approach, utilizing qualitative data collected through participatory observation, in-depth interviews, archival records, and literature reviews. The results revealed that the nugal agriculture embodied rich local knowledge about forest conservation efforts reflected in each process. The community practiced the nugal agriculture carefully with adherence to customary norms that regulated forest management. The findings of this study address the prevailing negative stigma associated with the nugal culture as practiced by the Dayak Kuhin community.
