Plagiarism Policy

Jurnal Teknologi dan Manajemen Informatika (JTMI) strictly opposes any form of plagiarism and academic dishonesty. We are committed to maintaining the highest standards of publishing ethics and ensuring that all published work represents original intellectual contributions.

1. Definition and Scope of Plagiarism

Plagiarism occurs when an author presents the work, ideas, data, or words of others as their own without proper acknowledgment or citation. In accordance with international academic publishing standards (including COPE guidelines), JTMI considers the following actions as violations of academic integrity:

• Direct Plagiarism: Unattributed word-for-word copying of another person’s work.

• Self-Plagiarism (Text-Recycling): Reusing significant portions of the author's own previously published work without proper citation or attribution.

• Duplicate or Substantially Overlapping Submission: Submitting the same manuscript (or a manuscript with substantially similar content) to multiple journals simultaneously or republishing previously published work.

• Inappropriate Paraphrasing: Altering a few words or sentence structures from a source while retaining the original idea and structure without providing a formal citation.

• Uncited AI Content Generation: Presenting text, code, or ideas generated by artificial intelligence (AI) tools as original author contributions without explicit disclosure and attribution.

2. Screening and Similarity Index Threshold

All submitted manuscripts undergo rigorous preliminary screening for similarity using Turnitin prior to entering the peer-review process.

• Maximum Similarity Threshold: Manuscripts submitted to JTMI must have an overall Turnitin Similarity Index of no more than 20%.

• Individual Source Limits: Matching text from a single source should generally not exceed 2–3% to ensure proper contextual synthesis and original phrasing.

• Items automatically excluded from similarity score calculations include properly cited reference lists/bibliographies, standard template text, and common methodological terminology.

3. Consequences and Actions Upon Detection

JTMI takes allegations of plagiarism seriously at every stage of the editorial and publishing pipeline:

• Detection During Pre-Review (Desk Evaluation):

  • If the similarity index exceeds 20% due to minor structural issues or inadequate citations, the manuscript will be sent back to the authors for revision before review.

  • If significant or uncredited copying is detected, the manuscript will be subject to immediate Desk Rejection without peer review.

• Detection During Peer Review or Production:

  • If plagiarism is identified during evaluation, editorial processing is suspended immediately. Authors will be asked to provide an explanation. Unacceptable responses will result in permanent rejection.

• Detection After Publication:

  • If plagiarism is proven in an already published article, the Editorial Board will issue a formal Article Retraction in accordance with COPE Retraction Guidelines. A notice of retraction will be attached to the article PDF, and the author's affiliated institution may be formally notified.
