Authorship Criteria & Contributor Standards

Authorship in JES must be grounded exclusively on substantive intellectual, conceptual, and empirical contributions to the research. In alignment with COPE standards and the CRediT (Contributor Roles Taxonomy) framework, all listed authors must fulfill all four standard criteria:

• Substantial contributions to the conception or design of the work, or the acquisition, analysis, or interpretation of data;
• Drafting the work or revising it critically for important intellectual content;
• Final approval of the version to be published; and
• Agreement to be accountable for all aspects of the work in ensuring that questions related to accuracy or integrity are appropriately resolved.

Contributors who provided purely administrative, financial, or routine technical assistance must be acknowledged in an Acknowledgements section rather than listed as authors. Ghost authorship, guest authorship, and honorary authorship are strictly prohibited.

Language Policy

JES accepts manuscripts written in Indonesian or English. Regardless of the language of the main text, every manuscript must include an abstract in both English and Indonesian. Authors may use the English or Indonesian article template available in the sidebar. Manuscripts must be written in clear, grammatically correct, and academically appropriate language; the editorial team may return submissions that require substantial language improvement before review.

Peer Review Process & Workflow

Submitted manuscripts must be original, unpublished, and not under consideration for publication elsewhere. All manuscripts undergo a rigorous double-blind peer review process conducted by at least two independent reviewers with expertise in the relevant subject area.

JES strives for a rigorous yet efficient review process. On average, authors can expect a first decision within 5 days, a peer review period of 14 days, a total submission-to-acceptance time of approximately 30 days, and publication within 10 days of acceptance. The journal is committed to a fair, transparent, and timely review process in accordance with best practices recommended by COPE (Committee on Publication Ethics). To ensure complete editorial accountability, articles published from Volume 6 (2027) onward will explicitly feature the complete genesis history (Received, Revised, Accepted, and Published dates).

Special Issue Policy

JES periodically publishes Special Issues dedicated to emerging and high-impact topics in engineering and applied science. Special Issues are guest-edited by recognized experts and undergo the same rigorous double-blind peer review process as regular submissions.

Proposals for Special Issues should include:

• A clear title and description of the proposed interdisciplinary theme;
• Relevance to the journal's scope and contemporary national/global research trends;
• Names, institutional affiliations, and Scopus/ORCID profiles of proposed Guest Editors;
• Proposed milestone timeline for submission, review, and publication.

Proposals may be submitted via the Contact page of this journal.

Artificial Intelligence (AI) Policy

JES recognizes the constructive assistance offered by Artificial Intelligence tools in scholarly writing while safeguarding academic transparency. The following policy applies to all submissions:

• Transparent Disclosure: Authors must provide an explicit statement prior to References indicating whether or not AI-assisted tools (e.g., ChatGPT, Gemini, Claude, Microsoft Copilot, Grammarly AI, DeepL, QuillBot, Perplexity) were utilized during the preparation of the manuscript. When used, the statement must name the tool, its version, and the purpose of use.
• AI Authorship Preclusion: In alignment with COPE standards, AI tools cannot be listed as authors or co-authors because non-human software cannot assume legal or ethical accountability for research assertions.
• Author Ownership & Integrity: Authors maintain full intellectual ownership and legal responsibility for the factual integrity, empirical datasets, citations, and originality of their published work, including the verification of any AI-assisted output.
• Permitted Scope: The use of AI is welcomed strictly for proofreading, translation support, grammar, and stylistic enhancement. Methodological designs, empirical data analyses, and substantive conclusions must reflect the authors' own scholarly synthesis.
• Prohibited Use: AI tools must not be used to fabricate data, generate fictitious references, or create or alter images and results in a manner that misrepresents the research.
• Reviewers & Editors: Confidential manuscripts must not be uploaded to public AI tools during the review and editorial process to protect author intellectual property.

This policy is fully harmonized with the position statement of the Committee on Publication Ethics (COPE).
