1. Before You Submit

• The manuscript must be original, not previously published, not under review elsewhere, and not presented at a conference, seminar or forum.
• All authors have approved the manuscript and agree with its submission to JSD.
• The research complies with ethical standards; approval numbers are available for studies involving humans, animals or protected biological resources.
• Read the Focus and Scope, Publication Ethics, Authorship, Plagiarism and Generative AI policies.

2. Language and Format

• Write in English (preferred) or Indonesian. Non-native English authors are strongly encouraged to have the manuscript proofread before submission.
• Use the official JSD template (Microsoft Word, .docx). Do not change the template styles, margins or font.
• Maximum length is 15 A4 pages, including tables, figures and references.
• Use SI units, standard nomenclature (IUPAC for chemistry, binomial nomenclature in italics for organisms) and define all abbreviations at first use.

3. Manuscript Structure

4. Tables, Figures and Equations

• Number tables and figures consecutively (Table 1, Figure 1) and cite each in the text before it appears.
• Table captions go above the table; figure captions go below the figure. Captions must be self-explanatory.
• Use horizontal lines only in tables (no vertical lines). State units in column headings and explain symbols in table notes.
• Figures must be original, sharp, at least 300 dpi, with labelled axes and units, and readable in greyscale. Upload original figure files as supplementary files.
• Images (micrographs, gels, blots) must not be manipulated beyond adjustments of brightness and contrast applied to the whole image.
• Write equations with the Word equation editor, centred and numbered consecutively on the right, e.g., (1). Define all symbols.

5. Citations and References (APA 7th)

JSD uses APA Style 7th edition. We strongly recommend using a reference manager such as Mendeley or Zotero with the APA 7th style.

• Use at least 15 references; at least 80% must be journal articles published in the last 10 years.
• List only works cited in the text, alphabetically by the first author's surname, with a 0.5-inch hanging indent.
• Include the DOI as https://doi.org/xxxxx whenever available.
• Avoid citing unpublished work, personal communications, theses and non-scholarly websites where possible.
