Abstract
The abstract must be written in both English and Indonesian. It should be informative and represent the entire content of the manuscript, from introduction to conclusion. The abstract must be written as a single narrative paragraph.
The structured abstract must not exceed 250 words and should include the following subheadings:
Background: Briefly describe the scope or context of the study, relevant previous research, and the justification for the novelty of the topic.
Objective: Clearly state the research objective and/or the hypothesis tested.
Methods: Describe the study design, including the use of cell cultures, animal models, or human subjects. Authors should also describe the interventions applied and the control groups (if applicable), as well as specific methods or procedures used.
Results: Present the most important research findings, including relevant statistical analysis results.
Conclusions: Provide a concise summary (1–2 sentences) highlighting the primary outcomes of the study, including potential clinical significance where applicable. Avoid overly general conclusions.
Keywords: Include 3–8 keywords or phrases placed at the end of the abstract to help readers identify relevant manuscripts. Keywords may include study subject groups. Avoid the use of adjectives as keywords.
Introduction
The Introduction must clearly state the NOVELTY of the study, including its originality and depth, by highlighting the unique differences between the present study and previous related studies.
The Introduction must also include a GAP ANALYSIS, demonstrating the importance of the study by justifying how it addresses limitations or gaps in existing research that have not been adequately explored.
The Introduction should concisely describe the magnitude of the research problem and provide a strong rationale for conducting the study. It must be supported by relevant and robust references and clearly state the research objectives. Authors should avoid discussing methods, data, results, or conclusions in this section. The length of the Introduction must not exceed one page.
Materials and Methods
This section must be complete and detailed, allowing other researchers to replicate the study exactly as reported. It should be written in a narrative form and divided into three subsections containing the following information:
Study Design and Subjects
Study design
Time and location of the study
Study population and sample
Sample size estimation
Sampling method
Inclusion and exclusion criteria
Ethical approval, including the Ethics Committee (EC) approval number
Data Collection and Measurement
Study variables (definitions and classifications/criteria, if applicable)
Instruments and materials used
Detailed description of study procedures, including measurements and interventions (e.g., methods for measuring body weight and height to determine nutritional status, frequency of measurements, personnel involved, and timing of measurements)
Study flow or procedures / types of interventions (particularly for experimental studies
Data Analysis
Statistical analyses used
Computer software employed
Results
Results should be presented in a logical sequence that follows the study flow. Generally, results should begin with the characteristics of the study subjects. Findings may be presented in narrative (textual) form, tables, or figures (graphs/diagrams). Information on loss to follow-up or subject drop-out (if any) should be reported. Presentation of individual subject data should be avoided, except in extreme cases. Subject identities must not be disclosed.
A maximum of 3–5 tables or figures is allowed per manuscript. Each table or figure must be referred to in the text. Tables and figures must be self-explanatory, with clearly presented numbers and units so that they do not rely on the text for interpretation. Titles of tables and figures must be in bold.
Duplication of information is not permitted; if data can be presented more clearly and concisely in narrative form, tables or figures should not be used. Tables or figures containing data from other sources (e.g., secondary data) must clearly indicate the original source.
Tables
Table titles should be placed above the table. Tables must be numbered consecutively using Arabic numerals (1, 2, 3, etc.). Each column must be labeled according to the variable presented (standard abbreviations may be used). Explanations of abbreviations, codes, or symbols should be provided as footnotes below the table, preferably using Arabic superscript numbers.

Figures
Figure titles should be placed below the figure. Each figure or graph must be cited in the text according to its numerical order. Figures must be self-explanatory, with clearly displayed numbers and units. Abbreviations, numbers, symbols, or arrows used in figures or captions must be defined below the figure, listed in alphabetical order. A minimum image resolution is not specified, but figures must be clearly visible when printed.
Discussions
The Discussion should begin with the main findings of the study, followed by an interpretation of their meaning. Authors should compare their findings with existing knowledge or previous studies and relate the results to clinical, social, and scientific aspects. Repetition of results already presented in the Results section is not permitted.
The use of textbooks, methodological manuals, classical books, or newspaper articles as comparative references should be avoided. Standard terminology and clear, correct language must be used. The Discussion should demonstrate conceptual clarity and logical flow between paragraphs. All abbreviations must be spelled out in full at their first appearance.
The Discussion must address three key elements:
How? — Describe the essence of the findings and highlight key results already presented in the Results section.
Why? — Provide a strong scientific explanation by linking results to fundamental concepts, hypotheses, and/or performance and analytical outcomes.
What else? — Compare the findings with previous studies, identifying consistencies or discrepancies and explaining possible reasons.
Conclusions
Conclusions should be written in narrative form, consisting of one or more paragraphs, based on the study findings and without reporting statistical values. Recommendations must be consistent with the conclusions drawn. Suggestions for future research should be included where applicable.
Acknowledgements
Acknowledgements should be stated appropriately and concisely, and addressed only to research funders and/or individuals who made significant contributions but do not meet the criteria for authorship.
Conflict of interest statement
Authors are required to declare any conflicts of interest.
References
References must be numbered according to the order of appearance in the manuscript using the Vancouver style. Citations in the text should be indicated using Arabic numerals in parentheses (e.g., (1)), not superscripts. Authors are encouraged to use reference management software such as Mendeley, Zotero, or EndNote to minimize citation errors. If such software is not used, references must strictly follow the journal’s reference format guidelines.
Journal titles must be abbreviated according to the official abbreviations listed in Index Medicus and the Index of Indonesian Learned Periodicals (PDIN 1974). Official journal abbreviations can be accessed at: https://www.ncbi.nlm.nih.gov/nlmcatalog
