Screening for Plagiarism

All manuscripts submitted to the Journal of Natural Sciences and Mathematics Research (JNSMR) are screened for textual similarity using Turnitin software. The maximum permitted similarity index is 20%. However, the similarity score alone does not determine whether plagiarism has occurred. Each similarity report is subject to editorial assessment to distinguish legitimate similarities, such as properly cited quotations, references, and commonly used scientific terminology, from potentially inappropriate use of existing work.

Plagiarism is a violation of scholarly integrity and publication ethics. In accordance with the classification described by Soelistyo (2011), plagiarism may take the following forms:

  1. Word-for-word plagiarism – Reproducing another author's words or passages without appropriate quotation, acknowledgment, or citation.
  2. Source plagiarism – Using another person's ideas, concepts, theories, methods, or findings without properly acknowledging the original source.
  3. Plagiarism of authorship – Presenting another person's work, research, or intellectual contribution as one's own.
  4. Self-plagiarism – Reusing substantial portions of one's previously published work without appropriate citation, disclosure, or a sufficiently distinct scholarly contribution. Manuscripts submitted to JNSMR must offer a clear contribution beyond the author's previous publications. Reusing previously published text, data, figures, or findings must be handled transparently and in accordance with applicable copyright, citation, and publication ethics requirements.

Manuscripts suspected of plagiarism or other forms of inappropriate textual reuse will be evaluated by the editorial team. Depending on the nature and severity of the concern, the journal may request clarification or revision, reject the manuscript, or take other appropriate actions in accordance with its publication ethics policies. A similarity score below 20% does not automatically establish that a manuscript is free from plagiarism, and a score exceeding 20% requires editorial evaluation rather than an automatic conclusion of misconduct.
