1. Manuscripts must be original, free from plagiarism, and must not have been previously published or be under consideration by another journal. If the manuscript has previously been presented at a seminar, workshop, conference, or other academic forum, the event must be clearly acknowledged.
2. Manuscripts must be prepared in Microsoft Word and submitted in DOC or DOCX format.
3. The manuscript must use A4 paper size with the following margins: top 3 cm, left 3 cm, bottom 3 cm, and right 3 cm.
4. The manuscript must be typed in one column using Garamond, 12 pt, with 1.5 line spacing.
5. Tables, charts, figures, and images must be embedded within the manuscript, clearly numbered, appropriately captioned, and presented in a readable format.
6. All manuscripts, including the title, abstract, keywords, main text, tables, figures, and references, must be written in English.
7. Manuscripts must follow the official Journal of Astronomy and Sharia Applications (JASA) article template.
8. Manuscripts should demonstrate clear academic relevance to the journal's Focus and Scope and, where appropriate, emphasize the relationship between astronomical science and sharia, Islamic law, or Muslim religious practices.

Original research articles should normally contain 4,500–7,000 words, excluding references.

The manuscript should be organized as follows:

The title must be concise, informative, and preferably no more than 15 words. It should clearly reflect the central issue, object of study, method, or major contribution of the manuscript.

Authors' names must be written without academic titles. Multiple authors should be listed according to their contribution and agreed authorship order.

Each author's institutional affiliation, city, and country must be clearly stated.

A valid email address should be provided for each author. Authors are strongly encouraged to provide an ORCID iD. The corresponding author must be clearly identified.

The abstract must be written in English, consist of approximately 200–250 words, and be presented as a single paragraph.

For original research articles, the abstract should briefly include:

• the academic problem or background;
• the purpose of the study;
• the research method;
• the principal findings;
• the main conclusion or scholarly contribution.

For review or conceptual articles, the abstract should identify the central problem, scope of analysis, approach, principal argument, and contribution.

Authors should provide 4–6 keywords representing the main concepts, methods, objects, or disciplinary areas of the manuscript.

The introduction should establish the academic significance of the study and should generally include:

• the research background and academic problem;
• the relevant state of the art;
• critical engagement with previous studies;
• the research or knowledge gap;
• the novelty or distinctive contribution of the study;
• the research objective or research question;
• the significance of the study for astronomy and sharia applications.

The introduction should provide sufficient international scholarly context and avoid excessive descriptive background.

The Methods section must clearly explain how the research was conducted and should include, where relevant:

• research design and approach;
• study location or observational site;
• data sources;
• instruments and software;
• astronomical parameters;
• observational or computational procedures;
• sampling or data selection;
• analytical methods;
• validation procedures;
• relevant ethical considerations.

For research involving astronomical observation, computation, photometry, geospatial analysis, calendrical calculation, or other scientific measurements, authors should provide sufficient methodological detail to enable evaluation and, where possible, replication.

For research involving sharia or Islamic legal analysis, authors should clearly explain the legal sources, interpretive framework, methodological approach, and relationship between astronomical evidence and legal reasoning.

The Methods section may be adapted for conceptual or systematic review articles according to the nature of the study.

The Results and Discussion section should present the findings clearly and analyze their academic significance.

Authors should:

• present empirical, observational, computational, textual, or legal findings systematically;
• interpret findings using relevant theories or analytical frameworks;
• compare the findings with previous national and international studies;
• explain similarities, differences, limitations, and implications;
• demonstrate the contribution of the findings to the development of astronomy and sharia applications.

Tables, figures, maps, astronomical images, graphs, and other visual materials should be used where they improve clarity and analytical depth.

This section may be divided into appropriate subsections.

The conclusion should synthesize the principal findings rather than merely repeat the Results and Discussion.

It should clearly state:

• the main answer to the research problem;
• the principal scholarly contribution;
• the implications of the findings;
• limitations, where relevant;
• recommendations or directions for future research.

All sources cited in the manuscript must appear in the reference list.

References should:

• be academically credible and directly relevant to the manuscript;
• prioritize peer-reviewed international journal articles, academic books, authoritative institutional documents, and primary sources;
• include recent literature, particularly from the last ten years, where relevant;
• retain classical or foundational works where necessary;
• include DOI information whenever available.

Authors are encouraged to engage with international literature relevant to the global development of astronomy, Islamic astronomy, sharia, and related interdisciplinary fields.

Journal of Astronomy and Sharia Applications (JASA) uses APA Style, 7th Edition for citations and references.

Authors must use the author-date citation system.

• One author: (Ilyas, 1997)
• Two authors: (Azhari & Ibrahim, 2020)
• Three or more authors: (Rahman et al., 2021)
• Direct quotation: (Azhari, 2015, p. 45)

Direct quotations of fewer than 40 words should be incorporated into the paragraph using quotation marks. Quotations of 40 words or more should be presented as block quotations in accordance with APA 7th Edition.

References to Qur'anic verses should clearly identify the surah and verse.

Example: (Qur'an 40:43)

References to Hadith should identify the compiler, collection, and hadith number whenever available.

Authors should ensure consistency in Arabic transliteration throughout the manuscript.

Authors are strongly encouraged to use reference management software such as Zotero, Mendeley, or EndNote to ensure consistency and accuracy.

The Research Notes section provides an opportunity for researchers to communicate significant preliminary findings, ongoing studies, methodological developments, observational reports, or concise scholarly contributions relevant to the Focus and Scope of JASA.

Research Notes may address topics such as:

• astronomical observations;
• crescent visibility;
• Hijri calendar data;
• prayer-time calculations;
• qibla measurements;
• eclipse observations;
• astronomical instrumentation;
• photometric measurements;
• geospatial applications;
• atmospheric or environmental astronomy;
• digital and computational astronomy;
• astronomy and sharia-related applications.

Research Notes must present academically significant material that has not been previously published.

The maximum length is 1,000 words, excluding references and a maximum of two tables or figures.

An abstract is not required.

Research Notes will be evaluated for originality, academic relevance, methodological clarity, readability, timeliness, and consistency with JASA's Focus and Scope.

JASA welcomes high-quality review articles that critically synthesize theories, methods, evidence, scholarly debates, and emerging developments relevant to astronomy and sharia applications.
