Plagiarism Policy

A. Plagiarism and Similarity Screening Policy

NUANSA INFORMATIKA is committed to originality, accurate attribution, and ethical scholarly publishing. All submitted manuscripts must be the authors' own work and must not be under consideration elsewhere.

B. Similarity Screening

Authors are required to submit an initial similarity report generated by Turnitin, iThenticate, or another reliable text-matching tool with the manuscript. The editorial team conducts an independent similarity screening before external peer review and may repeat screening before publication. Manuscripts with a similarity index exceeding 20%, after excluding references and other justified non-substantive matches, may be returned for clarification or revision or rejected depending on the nature of the overlap.

C. Interpretation of Similarity Reports

A similarity percentage is a screening indicator, not an automatic finding of plagiarism. Editors assess the location, extent, context, source attribution, and nature of matched passages. Properly cited technical terminology and standard methodological expressions must be distinguished from unattributed copying. Conversely, serious unattributed copying may warrant action even when the overall similarity score is below 20%.

D. Prohibited Practices

Unethical practices include unattributed reproduction of words, figures, tables, software code or data; misleading paraphrasing; duplicate submission; redundant publication; unattributed recycling of substantial parts of the authors' earlier work; fabricated references; and manipulation of citations. Reuse of previously published material requires appropriate acknowledgment and permission where needed.

E. Editorial Response

If a concern is identified, the editors may request source documents and an explanation, seek independent advice, require revision, reject the manuscript, or investigate a published article under the Publication Ethics policy. Authors must be given an appropriate opportunity to respond before a final determination is made. Corrections, expressions of concern, or retractions may be issued for published articles where justified. Decisions are documented confidentially.

F. Contact
