Plagiarism Policy

Plagiarism Policy and Screening
JPK (Jurnal Pendidikan Khusus) does not tolerate plagiarism. All submitted manuscripts are screened for similarity and checked for originality.
1Definition of Plagiarism

Plagiarism is the use of another person's words, ideas, data, figures, or results without proper acknowledgment, presenting them as one's own work. In JPK, plagiarism includes:

  • Copying text, in whole or in part, from another source without quotation marks and citation.
  • Paraphrasing another work too closely, or without citing the source.
  • Reusing data, tables, figures, instruments, or images without permission and attribution.
  • Translating another author's work and presenting it as original.
  • Self-plagiarism: reusing one's own published or submitted work (text, data, or results) without disclosure and citation, including duplicate or redundant publication.
  • Submitting content generated by AI tools without disclosure, or passing it off as original thought (see the Generative AI Policy).
2Similarity Screening

Every manuscript is screened with similarity-detection software before it is sent for review. The screening tool is Turnitin.

Acceptable similarity
Overall similarity of up to 20%, excluding references, quotations, and common phrases.
Single-source limit
No single source should account for more than 20% of the text.
Higher similarity
Manuscripts above the limit are returned to the authors for revision or rejected, depending on the editor's assessment.

Similarity percentage is only an indicator. Editors review the report and the context before making a decision.

3Responsibility of Authors
  • Submit only original work and cite every source used, including the authors' own earlier work.
  • Use quotation marks and page numbers for direct quotations, and cite paraphrased ideas.
  • Disclose related manuscripts, theses, dissertations, and conference papers in the cover letter, and cite them when they overlap.
  • Obtain permission for any third-party material reproduced in the article.
  • Keep records of raw data and sources, and provide them if the editors ask.
4How Plagiarism Is Handled
  1. At submission: editors run the similarity check. Manuscripts that fail are returned or rejected before review.
  2. During review: reviewers who suspect plagiarism or duplicate publication inform the editor, who investigates.
  3. After publication: if plagiarism is found in a published article, the editors follow the journal's correction and retraction procedure.

Authors are given a chance to explain before a decision is made. Sanctions depend on the scale and intent of the misconduct.

5Possible Consequences
Minor overlap
The authors are asked to revise, rewrite, and cite properly.
Serious plagiarism
The manuscript is rejected.
Published article
Correction or retraction notice, and the authors' institution may be informed.
6Reporting a Concern

Readers, reviewers, and authors who suspect plagiarism in a submitted or published article can contact the editorial office with the article details and the evidence. Reports are handled confidentially.
