Plagiarism Screening Policy

All manuscripts submitted to MACHINERY: Jurnal Teknologi Terapan undergo similarity screening using Turnitin. The journal applies a maximum similarity index of 20%.

Similarity reports are interpreted through editorial assessment. A similarity index below 20% does not automatically establish originality or guarantee acceptance, while a higher score requires examination of the nature and sources of the overlap. Plagiarism may occur regardless of the overall similarity percentage.

Forms of Plagiarism

  1. Word-for-Word Plagiarism
    Reproducing another author’s words without appropriate quotation formatting and accurate citation. Citing a source alone does not justify presenting its exact wording as original text.

  2. Plagiarism of Ideas or Sources
    Using another person’s ideas, arguments, interpretations, methods, or findings without clearly acknowledging the original source. Paraphrased material also requires appropriate citation.

  3. Plagiarism of Authorship
    Presenting another person’s manuscript, research, or other scholarly work as one’s own, whether wholly or substantially.

  4. Self-Plagiarism and Redundant Publication
    Reusing substantial portions of one’s previously published text, data, or findings without appropriate citation and disclosure, or publishing substantially the same research in more than one journal without legitimate justification and editorial approval.

    Manuscripts that build on an author’s previous publications must clearly acknowledge those publications and explain the new contribution. Changes in wording, title, or presentation alone do not establish originality. There is no universal percentage of reused material that makes a manuscript an acceptable new publication.

Editorial Action

When inappropriate overlap or suspected plagiarism is identified, the editorial team may request clarification, require revision, reject the manuscript, or investigate further, depending on the nature and extent of the concern.

If plagiarism is identified after publication, the journal may issue a correction or retraction, as appropriate, in accordance with its publication ethics policies. Authors will be given an opportunity to respond to the concerns raised.
