Originality Requirement

By submitting a manuscript to Jurnal Sinar Manajemen, authors confirm that the work is original, has not been published previously in substantially the same form, and is not simultaneously under consideration for publication by another journal.

Material reproduced or adapted from other sources must be appropriately cited and, where required, accompanied by permission from the relevant copyright holder.

What Constitutes Plagiarism

Plagiarism may include, but is not limited to:

• copying text from another source without appropriate quotation, citation, or attribution;
• paraphrasing another person's ideas or arguments without appropriate acknowledgement;
• presenting another person's data, tables, figures, images, models, methods, or other intellectual contributions as one's own;
• translating material from another language and presenting it without appropriate acknowledgement of the original source;
• reproducing substantial portions of previously published material without appropriate attribution or justification;
• using material obtained from unpublished manuscripts, reports, theses, dissertations, conference papers, websites, or other sources without appropriate acknowledgement.

Similarity Screening

Submitted manuscripts may be screened using plagiarism-detection or text-similarity software as part of the editorial assessment. Similarity reports are used as screening tools to assist editors in identifying potentially problematic textual overlap.

A similarity percentage alone does not establish whether plagiarism has occurred. Editors assess the nature, source, extent, distribution, and context of textual overlap, including whether material has been properly quoted, paraphrased, cited, or otherwise attributed.

Interpretation of Similarity Reports

Jurnal Sinar Manajemen does not determine plagiarism solely on the basis of an overall similarity score. A manuscript with a relatively low similarity percentage may still contain unacceptable plagiarism if significant material has been copied without attribution. Conversely, legitimate similarities may arise from references, standard terminology, methodological descriptions, properly quoted material, institutional names, or other unavoidable textual elements.

Editorial assessment therefore focuses on the substantive character of the overlap rather than relying exclusively on a numerical similarity threshold.

Text Recycling and Reuse of Authors' Previous Work

Authors must also be transparent when reusing material from their own previously disseminated or published work. Substantial reuse of previously published text, data, figures, tables, or results without appropriate citation or disclosure may constitute inappropriate text recycling or redundant publication.

Where a submitted manuscript develops or extends previous work by the same authors, the earlier work must be appropriately cited and the manuscript must provide a sufficiently distinct and substantive scholarly contribution.

Duplicate and Redundant Publication

Authors must not submit substantially the same manuscript to more than one journal simultaneously. The publication of substantially overlapping research in multiple publications without appropriate disclosure, cross-reference, or legitimate scholarly justification is not acceptable.

Authors must disclose relevant previous publications, pre-existing reports, conference publications, or related manuscripts when these materials overlap substantially with the submitted work.

Editorial Action Before Publication

When potentially inappropriate textual overlap is identified before publication, the editorial team may take one or more of the following actions depending on the nature and seriousness of the concern:

• request clarification from the authors;
• request correction of citations, quotations, paraphrasing, or attribution;
• require revision of overlapping sections;
• suspend editorial processing while the concern is assessed;
• decline the manuscript when plagiarism, substantial duplication, or other serious integrity concerns are established.

Plagiarism Identified After Publication

Allegations of plagiarism involving a published article will be assessed regardless of when the concern is raised. The journal may request explanations and supporting information from the authors and may consult relevant parties when necessary.

Where plagiarism or substantial inappropriate duplication is established after publication, Jurnal Sinar Manajemen may issue a correction, retraction, or other appropriate editorial notice depending on the nature and severity of the problem. The journal may also contact the authors' institution or another appropriate authority when an institutional investigation is warranted.

Author Responsibility

Authors are responsible for ensuring the originality and proper attribution of all material included in their manuscripts. Authors should carefully review quotations, paraphrases, citations, figures, tables, data, and other reused materials before submission and ensure compliance with applicable copyright and licensing requirements.

Authors are also responsible for the integrity of manuscript content produced or revised with the assistance of artificial intelligence or other automated tools. The use of such tools does not transfer responsibility for plagiarism, inaccurate attribution, fabricated citations, or copyright infringement away from the authors.

Publication Integrity

Jurnal Sinar Manajemen evaluates suspected plagiarism and related publication integrity concerns on the basis of evidence and the substantive nature of the overlap. Editorial action will be proportionate to the seriousness of the concern and will be undertaken in accordance with the journal's Publication Ethics policy and recognised principles of responsible scholarly publishing.
