Plagiarism Prevention Policy

Indonesian Economic Justice Review (IEJR) is committed to maintaining the highest standards of academic integrity and originality. The journal considers plagiarism and other forms of inappropriate appropriation of intellectual work to be serious violations of publication ethics. This policy is developed in accordance with the principles and best practices of the Committee on Publication Ethics (COPE) and other recognized standards of scholarly publishing.

1. Definition of Plagiarism

Plagiarism is the use, reproduction, appropriation, or presentation of another person's words, ideas, arguments, data, findings, research materials, or other intellectual contributions as one's own without appropriate acknowledgment or citation.

Plagiarism may include, but is not limited to:

  • Directly copying words or sentences without quotation and proper citation;
  • Substantial copying or close paraphrasing of another work without appropriate attribution;
  • Presenting another person's ideas, arguments, theories, data, or findings as original;
  • Copying or reproducing tables, figures, charts, or other materials without appropriate acknowledgment or permission where required;
  • Translating and presenting another person's work as original without proper attribution;
  • Reusing substantial portions of one's own previously published work without appropriate disclosure and citation (self-plagiarism or redundant publication);
  • Combining passages or ideas from multiple sources without adequate attribution (mosaic plagiarism); and
  • Any other practice that misrepresents the originality or source of intellectual material.

Plagiarism may occur intentionally or unintentionally. Authors are responsible for ensuring that all sources and intellectual contributions are appropriately acknowledged.

2. Originality Requirement

Manuscripts submitted to IEJR must be original scholarly works and must not have been published previously in substantially the same form.

A manuscript submitted to IEJR must not be under simultaneous consideration by another journal. Authors are required to disclose any substantially related manuscripts, conference papers, working papers, preprints, book chapters, theses, dissertations, or other publications that may overlap with the submitted work.

The existence of legitimate prior dissemination does not automatically constitute plagiarism. However, authors must provide transparent disclosure and appropriate citation so that editors can assess the degree and nature of any overlap.

3. Plagiarism Screening

All submitted manuscripts may undergo plagiarism and similarity screening as part of the journal's editorial process.

Plagiarism screening may be conducted:

  • During the initial editorial screening;
  • Before peer review;
  • During the revision process, where necessary; and
  • Before final publication, where appropriate.

The journal may use recognized plagiarism-detection or text-similarity software to identify potential overlap between the submitted manuscript and existing scholarly or publicly available materials.

A similarity score is not, by itself, evidence of plagiarism. Editorial assessment considers the nature, location, extent, source, and context of the identified similarities. Properly cited quotations, commonly used terminology, references, methodological descriptions, and other legitimate similarities may contribute to a similarity score without constituting plagiarism.

4. Similarity Assessment

There is no single similarity percentage that automatically determines whether a manuscript constitutes plagiarism. Editors will assess similarity reports on a case-by-case basis.

Particular attention will be given to:

  • Unattributed verbatim copying;
  • Substantial similarity in distinctive arguments or analytical structures;
  • Reproduction of data, tables, figures, or research findings without attribution;
  • Extensive paraphrasing that does not adequately acknowledge the original source;
  • Similarity involving the central contribution or substantive parts of the manuscript; and
  • Evidence of systematic or deliberate appropriation.

The journal may request clarification or revision where similarities appear to result from inadequate citation or paraphrasing. Where substantial plagiarism is suspected, the journal may initiate a formal publication-ethics assessment.

5. Responsibilities of Authors

Authors are primarily responsible for ensuring the originality and academic integrity of their manuscripts.

Authors must:

  • Properly cite all sources used in the manuscript;
  • Clearly distinguish their own arguments and findings from those of other authors;
  • Use quotation marks and appropriate citations for directly quoted material;
  • Properly paraphrase and cite sources rather than merely changing a few words or sentence structures;
  • Obtain appropriate permission for copyrighted materials where required;
  • Disclose relevant prior publications and overlapping manuscripts;
  • Ensure that all submitted material accurately represents the authors' own scholarly contribution; and
  • Cooperate with the journal if questions concerning originality or plagiarism arise.

Authors should retain appropriate documentation concerning their research and sources so that questions about originality can be addressed when necessary.

6. Self-Plagiarism and Redundant Publication

IEJR recognizes that authors may legitimately build upon their previous research. However, authors must not reproduce substantial portions of their previously published work without appropriate citation, disclosure, and justification.

Reusing text, data, analysis, or other material from an author's previous publication may constitute self-plagiarism or redundant publication where the reuse is substantial and creates a misleading impression of originality.

Where previous work is directly relevant, authors should clearly identify and cite the earlier publication and explain the contribution of the new manuscript.

7. Plagiarism Involving Translated Material

Plagiarism includes translating another person's work from another language and presenting the translated material as original without proper attribution.

The fact that the original source is written in a different language does not remove the obligation to acknowledge the source.

Authors who use translated material must provide appropriate citation to the original work and, where relevant, identify the material as a translation or adaptation.

8. Plagiarism Involving Artificial Intelligence

The use of artificial intelligence (AI) tools does not remove an author's responsibility to ensure originality and proper attribution.

Authors must not use AI tools to reproduce, paraphrase, translate, or generate material derived from existing sources in a manner that conceals the original source or creates a misleading impression of authorship or originality.

Authors remain responsible for verifying AI-assisted content, citations, quotations, references, and claims.

AI tools must not be used as a means to circumvent plagiarism detection or academic-integrity requirements.

Where required by the journal's AI policy, authors should disclose material use of AI in the preparation or development of the manuscript.

9. Procedures for Suspected Plagiarism

When potential plagiarism is identified, the journal will assess the matter in accordance with applicable publication-ethics principles and COPE guidance.

Depending on the circumstances, the journal may:

  1. Request an explanation from the author(s);
  2. Request clarification, source documentation, or revised text;
  3. Reject the manuscript before publication;
  4. Suspend the editorial or peer-review process while the matter is assessed;
  5. Contact the author's institution or relevant research-integrity authority where appropriate;
  6. Issue a correction if an article has been published and the issue can be appropriately corrected;
  7. Publish an Expression of Concern where serious concerns exist but the available evidence is inconclusive; or
  8. Retract the article where plagiarism substantially undermines the integrity of the published record.

The action taken will depend on the seriousness, extent, nature, and circumstances of the suspected plagiarism.

10. Post-Publication Plagiarism

Plagiarism concerns may be raised even after an article has been published.

Any credible allegation of plagiarism in a published article will be assessed by the journal. Where substantial plagiarism is confirmed, the journal may take appropriate corrective action, including correction, Expression of Concern, or retraction.

Any retraction or correction will be clearly linked to the original article and will explain the reason for the editorial action, in accordance with accepted publication-ethics practices.

11. False or Malicious Allegations

The journal takes allegations of plagiarism seriously but also recognizes the importance of protecting authors from unfounded or malicious accusations.

Allegations should be supported by credible evidence where possible. The journal will assess allegations objectively and confidentially and will provide relevant authors with an opportunity to respond before taking substantive action, except where immediate action is necessary to protect the integrity of the scholarly record.

12. Editorial and Reviewer Responsibilities

Editors and reviewers are expected to maintain vigilance concerning potential plagiarism and other forms of publication misconduct.

Reviewers who identify substantial similarity between a submitted manuscript and previously published work should notify the editor and provide relevant evidence or references where possible.

Reviewers must not use unpublished material from a manuscript for their own research or disclose confidential information obtained through the review process.

Editors are responsible for evaluating plagiarism concerns fairly and consistently and for taking appropriate action in accordance with the journal's publication-ethics procedures.

13. Commitment to Academic Integrity

IEJR is committed to protecting the integrity of the scholarly record and promoting a culture of responsible research and citation practices.

The journal does not regard plagiarism prevention as solely a technical similarity-checking exercise. Rather, plagiarism prevention is part of a broader commitment to academic honesty, intellectual responsibility, transparency, proper attribution, and respect for the work of other scholars.

The journal reserves the right to update this policy in accordance with developments in international publication-ethics standards, including guidance issued by COPE and other recognized scholarly organizations.
