Jurnal Rekayasa Industri (JRI) is strictly committed to upholding the highest standards of publication ethics and taking all necessary measures against any publication malpractice. This statement is compiled in alignment with international guidelines, including the Principles of Transparency and Best Practice in Scholarly Publishing from the Committee on Publication Ethics (COPE). The Editorial Board, publisher, reviewers, and authors must adhere fully to these ethical principles.

FOR AUTHORS

• Originality & Preprints: All submitted manuscripts must be original works that have not been published previously and are not currently under consideration elsewhere. Submissions derived from preprints in open repositories or conference proceedings are acceptable only if substantially revised and expanded.

• Plagiarism & Duplication: Plagiarism in any form is strictly unacceptable. Manuscripts are screened using Turnitin/Plagiarism Checker software; submissions with a similarity index exceeding 20% will be returned or rejected. Simultaneous submissions of identical or overlapping data to multiple journals constitute severe publication misconduct.

• Redundant Publication & Salami Slicing: Unnecessary division of a single study into multiple fragmented manuscripts (salami slicing) is strongly discouraged and grounds for rejection.

• Citations & References: Authors must appropriately cite all primary sources that influenced their research. Private communications or unverified sources must not be cited unless publicly accessible. Authors are urged to provide active DOIs/permalinks for all references.

• Authorship & Contributorship: Authorship credit must strictly reflect substantial contribution to the work based on the NISO CRediT (Contributor Roles Taxonomy) framework (Conceptualization, Methodology, Software, Formal Analysis, Investigation, Data Curation, Writing - Original Draft, Writing - Review & Editing, Supervision, Project Administration, Funding Acquisition). Ghost, guest, or gift authorship is strictly prohibited. Non-substantive contributions must be acknowledged in the Acknowledgments section.

• Safety & Hazard Identification: Manuscripts involving hazardous industrial equipment, chemical procedures, or unusual physical risks must explicitly identify these hazards for replication safety.

• Human/Worker Studies & Ethics: Studies involving human participants, factory workers, or ergonomics evaluations must confirm ethical clearance, safety compliance, and informed consent.

• Conflict of Interest & Funding: Authors must disclose any financial, commercial, or personal conflicts of interest. All external research funding, grants, and sponsor roles must be explicitly stated in the Funding section.

• Image Integrity: Manipulating figures or images beyond necessary brightness/contrast adjustments is prohibited. Raw high-resolution files should be uploaded separately if required.

• Errors in Published Works: Authors are obligated to notify the Editors immediately upon discovering significant errors in their published papers and cooperate to issue formal errata or retractions.

FOR EDITORS

• Publication Decision: The Editor-in-Chief and assigned handling editors are responsible for deciding which submitted manuscripts will be published based strictly on peer-review evaluations by independent domain experts.

• Fairness & Non-Discrimination: Manuscripts are evaluated solely on scientific merit, methodological validity, and scope relevance, without regard to authors' race, gender, nationality, religious beliefs, political philosophy, or institutional affiliation.

• Confidentiality: Editors must not disclose details regarding submitted manuscripts to anyone other than the corresponding author, assigned reviewers, and publisher representatives. Unpublished data or ideas obtained during peer review must not be used for personal research.

• Conflict of Interest Recusal: Editors with financial, institutional, or personal conflicts of interest regarding a submission (including shared affiliation with authors) must recuse themselves from handling the manuscript.

• Addressing Misconduct: Editors will investigate allegations or complaints regarding research integrity, following COPE procedures regardless of when the publication occurred.

FOR REVIEWERS

• Role & Objectivity: Reviewers provide objective scientific critiques regarding manuscript substance, validity, and industrial relevance. Reviews must be free from personal or derogatory comments.

• Promptness & Recusal: Appointed reviewers who feel unqualified or are unable to meet review deadlines must notify the editor immediately to be excused.

• Confidentiality: Manuscripts received for review are privileged, confidential documents and must not be shared, discussed, or used for personal advantage.

• Conflict of Interest: Reviewers must decline assignments involving manuscripts where they hold competing, collaborative, or other conflicts of interest with the authors or institutions.

• Citation Integrity: Reviewers must identify missing relevant literature but must not demand citation of their own publications unless scientifically justified.

FOR PUBLISHER

• Editorial Independence: Universitas Widya Mataram, as the publisher of JRI, guarantees that commercial, financial, or institutional interests will never influence editorial decisions.

• Legal & Ethical Support: The publisher collaborates with the Editorial Board to resolve legal disputes, ethical complaints, and retraction procedures in accordance with COPE best practices.

• Digital Preservation: The publisher ensures continuous online availability, DOI assignment, and long-term digital archiving of published metadata and full texts in cooperation with the National Library of the Republic of Indonesia.
