JOINS is committed to maintaining the integrity of the scholarly record. All parties involved in the publication process (authors, reviewers, and editors) are expected to follow the principles below. JOINS refers to the guidelines of the Committee on Publication Ethics (COPE): 

Duties of Authors
1. Originality and plagiarism. Manuscripts must be original, must not be published elsewhere, and must not be under review by another journal. All manuscripts are checked with Turnitin; those with a similarity index above 20% (excluding the bibliography) may be returned or rejected.
2. Data integrity. Authors must not fabricate, falsify, or manipulate data, results, or citations. Data should be presented honestly, and authors should be prepared to provide the data or supporting materials on request.
3. Proper citation. All sources used must be cited properly, and permission must be obtained for material that requires it. Authors are responsible for any intellectual property issues and their legal consequences.
4. Authorship. All listed authors must have made a significant contribution to the work and must have approved the final manuscript and its submission. No one who meets these criteria may be omitted, and no one who does not may be included.
5. Conflicts of interest. Authors must declare any financial or personal relationship that could influence the work.
6. Duplicate and redundant submission. Authors must not submit the same work to more than one journal at the same time, and must not publish the same findings in more than one place without disclosure.
7. Preprints. Authors may post a preprint but must inform the editor at submission so that double-blind review can be handled appropriately.
8. Use of AI tools. AI tools may be used as assistive tools only. They cannot be listed as authors, and authors remain fully responsible for the accuracy and integrity of the entire manuscript, including every reference. AI must not be used to fabricate data, results, or citations.
9. Corrections. If authors discover a significant error in their published work, they must promptly notify the editors so that a correction or retraction can be made.
10. Revision. Authors must respond to reviewers' and editors' comments in good faith and complete the revision process, or inform the editors if they wish to withdraw the manuscript.

Duties of Reviewers
1. Review manuscripts objectively, constructively, and within the agreed time. Reviewers who feel unqualified or unable to meet the deadline should decline the invitation.
2. Treat manuscripts and review reports as confidential. They must not be shared, discussed with others, or uploaded to publicly available AI tools.
3. Declare any conflict of interest and decline the review if one exists.
4. Not use unpublished material from a manuscript for personal advantage.
5. Notify the editors if they suspect plagiarism, fabrication, or other misconduct.

Duties of Editors
1. Decide on manuscripts based solely on their scientific quality and relevance, regardless of the authors' identity, affiliation, or nationality.
2. Maintain the confidentiality of manuscripts and reviewers, and uphold the double-blind process.
3. Declare any conflict of interest and hand the manuscript to another editor if one exists.
4. Ensure that complaints and allegations of misconduct are handled fairly and promptly.

Handling Misconduct, Corrections, and Retractions
Allegations of plagiarism, data fabrication, duplicate publication, or other misconduct are investigated by the editors in line with COPE guidelines (https://publicationethics.org). Authors are given the opportunity to respond. Depending on the findings, the editors may reject the manuscript, publish a correction, or retract the published article. Retracted articles remain accessible with a clear retraction notice. Concerns or complaints can be sent to jurnal@joins.dinus.ac.id.
