Plagiarism Policy and Screening

Indonesian Journal of Economics (IJE) is committed to maintaining the highest standards of integrity and academic honesty. Every manuscript submitted to the journal is subject to a mandatory plagiarism screening process to ensure the originality of the work.

1. Plagiarism Screening Tool

All submitted manuscripts will be screened for plagiarism and self-plagiarism using Turnitin or iThenticate software before they are sent to reviewers.

2. Similarity Threshold

  • The maximum allowable Similarity Index is 20%.

  • The similarity score for a single source must not exceed 3%.

  • The screening process typically excludes the Bibliography/References and Quoted Material (properly cited within quotation marks).

3. Types of Plagiarism

IJE strictly prohibits all forms of plagiarism, including but not limited to:

  • Direct Plagiarism: Copying someone else's work word-for-word without attribution.

  • Self-Plagiarism: Reusing significant portions of the author’s own previously published work without proper citation or notification to the editor.

  • Mosaic Plagiarism: Patching together phrases and ideas from various sources without original thought or proper citation.

  • Data Fabrication or Falsification: Manipulating research data or results to provide a false representation of the findings.

4. Consequences of Plagiarism

The editorial board of IJE handles plagiarism cases based on the severity of the violation:

  • Minor (Below 20% but lacks proper citation): The manuscript will be returned to the author for revision and proper referencing.

  • Moderate (21% - 40%): The manuscript will be rejected immediately, and the author will be given a formal warning.

  • Severe (Above 40% or clear evidence of data theft): The manuscript will be rejected, and the author(s) may be blacklisted from submitting to the Indonesian Journal of Economics for a specific period (e.g., 2–3 years). Their home institution may also be notified in extreme cases.

5. Policy for Post-Publication Plagiarism

If plagiarism is discovered after an article has been published, the journal will conduct an investigation. If proven, the article will be retracted (withdrawn), and a formal "Retraction Notice" will be published on the journal's website to inform the academic community.


Editorial Note: We highly recommend that authors perform an independent plagiarism check before submitting their manuscripts to avoid delays or rejection.
