Plagiarism and Similarity Screening Policy

Al-Adalah: Jurnal Hukum dan Politik Islam is committed to originality, academic integrity, and responsible scholarly communication. All submitted manuscripts are screened for textual similarity using Turnitin before external peer review and may be screened again at later stages of the editorial process.

Similarity reports are evaluated qualitatively by the editorial team. A similarity percentage is a screening indicator and is not, by itself, proof of plagiarism or originality. The editors consider the source, extent, location, and nature of matched text, including quotations, references, methodological descriptions, previously published material, and unattributed copying.

As an internal screening indicator, an overall similarity score of 25% or higher will normally trigger closer editorial examination. However, manuscripts with lower scores may still contain plagiarism, and manuscripts with higher scores may contain legitimate matches. No fixed percentage automatically determines an editorial decision.

Prohibited practices include, but are not limited to:

1. Direct plagiarism: copying words, figures, tables, data, or other intellectual content without proper quotation, permission where required, and attribution;
2. Substantial plagiarism: reproducing a significant part of another work, argument, analysis, or research finding without appropriate acknowledgement;
3. Improper paraphrasing: rewriting another author's work with insufficient originality or without proper citation;
4. Self-plagiarism or text recycling: reusing substantial parts of an author's previously published work without transparent citation and disclosure;
5. Duplicate or redundant publication: publishing or submitting substantially the same work to more than one journal without legitimate justification and full disclosure;
6. Citation manipulation: adding irrelevant or unnecessary citations to influence citation metrics or satisfy improper requests; and
7. Fabricated or falsified content: inventing, altering, or misrepresenting data, sources, evidence, findings, or references.

When misconduct is suspected, the journal may request an explanation and supporting documentation, suspend the review process, require revision, reject the manuscript, contact the authors' institution or another journal where appropriate, or take post-publication action.

Cases are handled fairly, confidentially, and in accordance with the journal's publication ethics procedures and relevant COPE guidance.
