Screening Plagiarism

Plagiarism Policy

Policy Statement

The Indonesian Journal of Islamic Economics and Finance (IJIEF) maintains a strict zero-tolerance policy against plagiarism and intellectual dishonesty. Any form of plagiarism identified in a manuscript submitted to IJIEF will be addressed promptly in accordance with Committee on Publication Ethics (COPE) guidelines, the journal’s publication ethics, and editorial governance.

Definition and Ethical Requirements

Plagiarism is defined as the appropriation, uncredited use, or close imitation of another author's language, ideas, data, or intellectual contribution, representing them as one's own original work. All manuscripts submitted to IJIEF must be original, unpublished, and not currently under consideration by any other journal or publisher.
  • Verbatim Text: Any text taken directly from another source must be explicitly identified using quotation marks, blockquote formatting, and complete attribution.
  • Permissions: Reproducing graphic materials, tables, datasets, or substantial textual passages beyond fair use limits requires written permission from the original copyright holder alongside proper citation.

Similarity Screening Workflow

All submitted manuscripts undergo automated similarity screening using industry-standard plagiarism detection software (e.g., Turnitin or iThenticate) during initial desk evaluation.
Similarity reports are interpreted qualitatively and contextually by the Managing Editor in consultation with the editorial team. The screening process accounts for legitimate, unavoidable overlaps, including:
  • References, bibliographies, and standard citation blocks.
  • Direct quotations from primary statutory provisions, regulatory frameworks, or classical Islamic texts.
  • Standardized economic models, mathematical formulas, and established methodological descriptions.
  • Discipline-specific technical terminology.

Similarity Index Guidelines

IJIEF applies the following similarity index thresholds as operational guidelines (subject to contextual editorial judgment):

Similarity Index Range Classification Editorial Action
Below 20% Acceptable Generally meets the initial threshold; minor citation or paraphrasing refinements may still be requested.
20% – 40% Substantial Revision Required Indicates notable overlap. Authors must perform extensive paraphrasing, fix citation practices, and resubmit.
Above 40% Unacceptable Indicates extensive textual overlap. Manuscripts in this range are normally subject to immediate desk rejection.

Revision and Final Editorial Assessment

When revisions are required due to similarity issues, authors must submit the revised manuscript together with an updated, post-revision similarity report demonstrating that all overlapping sections have been properly addressed.
The final publication decision relies on both the technical similarity assessment and qualitative editorial judgment, ensuring that IJIEF upholds the highest standards of scientific integrity.
