TURNITIN SCREENING ORIGINALITY RESEARCH INTEGRITY COPE GUIDELINES

EDITORIAL COMMITMENT

Policy Statement

Jurnal Indo-Islamika, published by the Graduate School of UIN Syarif Hidayatullah Jakarta, Indonesia, is committed to maintaining the originality, authenticity, intellectual integrity, and scholarly quality of all manuscripts submitted for publication.

The journal recognizes plagiarism as a serious violation of publication ethics because it misrepresents the origin of scholarly ideas, arguments, evidence, and intellectual contributions. Authors are required to submit original manuscripts and provide accurate acknowledgment of all sources used in their research.

To support the evaluation of manuscript originality, Jurnal Indo-Islamika uses Turnitin as its similarity-detection software. Manuscripts submitted to the journal must achieve an overall similarity index below 20% to satisfy the journal's similarity-screening requirement.

The similarity score is an initial indicator of textual overlap rather than a direct measurement of plagiarism. Editorial decisions are based on a contextual examination of the similarity report, the nature of the matching material, the adequacy of citations, and the seriousness of any identified integrity concerns.

This policy follows the principles of responsible scholarly publishing and is informed by the Committee on Publication Ethics (COPE) guidance concerning suspected plagiarism in submitted manuscripts and published articles.

Important: A similarity score of 20% or higher does not meet the journal's screening requirement. However, a high similarity score does not automatically establish plagiarism, and a score below 20% does not guarantee that a manuscript is free from plagiarism.

SECTION 01 • INTELLECTUAL INTEGRITY

1. Definition and Scope of Plagiarism

Plagiarism occurs when an individual uses another person's words, ideas, arguments, data, research findings, interpretations, images, methods, or other intellectual contributions without appropriate acknowledgment and presents such material as original work.

Plagiarism may occur through direct copying, inadequate paraphrasing, unattributed translation, misappropriation of ideas, or the reuse of previously published material without proper citation or disclosure.

The requirement for appropriate attribution applies regardless of whether the original material comes from a journal article, book, thesis, dissertation, conference proceeding, archival document, website, research report, unpublished manuscript, or another scholarly source.

Permission to reuse material does not remove the obligation to identify and acknowledge its original source. Similarly, the reuse of substantial portions of an author's own previously published work without appropriate disclosure may constitute inappropriate self-plagiarism or redundant publication.

For research in Islamic studies and the humanities, the journal emphasizes accurate attribution when using Qur'anic interpretations, hadith scholarship, classical Islamic literature, historical documents, archival records, translations, ethnographic materials, and contemporary scholarly arguments.

Authors must distinguish their original analysis from the intellectual contributions of earlier scholars. The use of classical Islamic sources should include appropriate textual references, while the use of particular scholarly translations, commentaries, critical editions, or interpretations must be acknowledged accurately.

Plagiarism may arise even when the original author is not readily identifiable, when copied material has passed through an intermediary source, or when the author of the submitted manuscript has previously published the material elsewhere.

SECTION 02 • TYPES OF UNACCEPTABLE REUSE

2. Forms of Plagiarism and Improper Reuse

Jurnal Indo-Islamika recognizes several forms of plagiarism and inappropriate reuse that may compromise scholarly originality and publication integrity.

2.1 Direct Plagiarism

Copying another author's words or passages verbatim without appropriate quotation marks, acknowledgment, or citation.

2.2 Paraphrasing Plagiarism

Rewriting another scholar's ideas, analysis, interpretations, or arguments in different words without acknowledging the original source.

2.3 Mosaic Plagiarism

Combining copied phrases, sentences, or passages from several sources, including partially modified wording, without adequate acknowledgment of the original material.

2.4 Translation Plagiarism

Translating another person's scholarly work into a different language and presenting the translation, interpretation, or argument as an original contribution without proper acknowledgment.

2.5 Self-Plagiarism and Redundant Publication

Reusing substantial portions of previously published text, arguments, findings, or research materials without adequate citation or disclosure, or presenting previously published research as a new and independent scholarly contribution.

2.6 Data, Evidence, and Idea Misappropriation

Presenting another researcher's data, documentary evidence, original interpretations, conceptual frameworks, methods, unpublished findings, or scholarly ideas as one's own intellectual work.

The seriousness of an identified violation is determined by the extent and nature of the misappropriation, its significance to the manuscript's scholarly contribution, and the circumstances established through editorial assessment.

SECTION 03 • TURNITIN AND EDITORIAL SCREENING

3. Similarity Screening and Editorial Assessment

All manuscripts submitted to Jurnal Indo-Islamika are subject to originality screening using Turnitin before proceeding to the peer-review stage. Additional similarity screening may be conducted following manuscript revision or before final publication.

The journal requires an overall similarity index below 20%. This threshold serves as an editorial screening requirement and does not replace the evaluation of originality, appropriate attribution, or the academic quality of a manuscript.

EDITORIAL SCREENING PROCEDURE

  1. The Editorial Team conducts an initial similarity screening using Turnitin and reviews the overall similarity index.
  2. The editor examines relevant matches and identifies the sources, extent, and context of textual overlap.
  3. The assessment considers direct quotations, bibliographic references, commonly used expressions, standard terminology, and appropriately acknowledged source material. Any permissible report exclusions must be applied consistently and reviewed by the editor.
  4. Manuscripts with a similarity index of 20% or higher do not satisfy the journal's screening requirement. Depending on the nature of the overlap, they may be returned for revision and rescreening or rejected.
  5. Where suspected plagiarism is identified, the editorial team examines the relevant evidence and may request clarification or supporting documentation from the corresponding author.
  6. The final editorial action is determined according to the seriousness of the identified concern, the author's response, the reliability of the evidence, and the journal's publication ethics standards.

IMPORTANT EDITORIAL DISTINCTION

A Turnitin similarity percentage is not equivalent to a percentage of plagiarism.

A manuscript may contain legitimate similarities through properly acknowledged quotations and references. Conversely, a manuscript with a low similarity score may still contain improperly attributed ideas, unattributed translations, or other forms of plagiarism that are not fully identified by similarity-detection software.

Authors are responsible for ensuring that their manuscripts comply with the journal's originality requirements before submission. When revision is permitted, authors must correct inappropriate overlap, provide accurate attribution, and submit a revised version that satisfies the journal's screening requirement.

The journal may reject manuscripts that repeatedly fail to meet the similarity requirement or contain confirmed plagiarism, even when authors have attempted to reduce the overall similarity percentage.

SECTION 04 • EDITORIAL CONSEQUENCES

4. Classification and Editorial Action

When potential plagiarism is identified, the Editorial Board evaluates the evidence and determines proportionate action according to the nature, extent, and seriousness of the violation.

The journal distinguishes minor, intermediate, and severe plagiarism for the purpose of consistent editorial decision-making.

CLASSIFICATION 01

4.1 Minor Plagiarism

Minor plagiarism involves limited unattributed wording, such as a short sentence or paragraph, without substantial appropriation of original research data, important findings, central arguments, or significant scholarly ideas.

Editorial Action:

The author may receive a written warning and a request to correct the affected material, provide proper citation or quotation, and revise the manuscript within the period specified by the editorial office. The revised manuscript may undergo another originality assessment before further consideration.

CLASSIFICATION 02

4.2 Intermediate Plagiarism

Intermediate plagiarism involves substantial unattributed passages, arguments, analytical interpretations, data, translations, or research findings taken from another source without appropriate acknowledgment.

Editorial Action:

Where the material violation is confirmed following editorial assessment and appropriate author clarification, the submitted manuscript will be rejected. The editorial office will communicate the decision and the principal reasons for rejection to the corresponding author.

CLASSIFICATION 03

4.3 Severe Plagiarism

Severe plagiarism involves extensive or systematic misappropriation of another researcher's scholarly work, including substantial reproduction of original findings, research data, methods, interpretations, theoretical arguments, or significant portions of published or unpublished material.

Editorial Action:

The manuscript will be rejected when severe plagiarism is confirmed. The Editorial Board may undertake further research-integrity assessment, refer the matter to the authors' institution where appropriate, or consider restrictions on future submissions. Any such restriction must follow a documented and fair editorial procedure, with consideration of the available evidence and the authors' response.

EDITORIAL FAIRNESS AND ACCOUNTABILITY

Suspected plagiarism must be assessed through relevant documentary evidence and appropriate editorial procedures. Authors should ordinarily be given an opportunity to explain the questioned material before a formal finding of misconduct is reached. Editorial decisions must distinguish between correctable attribution errors, substantial plagiarism, and serious research-integrity violations.

SECTION 05 • POST-PUBLICATION INTEGRITY

5. Plagiarism Identified After Publication

When concerns about possible plagiarism arise after an article has been published, Jurnal Indo-Islamika will evaluate the available evidence in accordance with its Publication Ethics, research misconduct procedures, and relevant COPE guidance.

The editorial team may examine the original sources, assess the nature and extent of the identified overlap, request clarification from the authors, and consult relevant specialists or research institutions when necessary.

Depending on the seriousness of the problem and its implications for the reliability and integrity of the scholarly record, editorial action may include publication of a correction, an Expression of Concern, or a formal retraction.

A correction may be appropriate when an identifiable attribution error can be remedied without substantially undermining the article's overall findings or scholarly contribution.

Retraction may be considered when extensive plagiarism, redundant publication, or other serious integrity concerns substantially compromise the validity or originality of the published work.

Post-publication measures are intended to protect the integrity of the scholarly record and inform readers accurately. Retraction should not be treated as an automatic penalty for minor or correctable citation errors.

SECTION 06 • AUTHOR OBLIGATIONS

6. Responsibilities of Authors

All authors submitting manuscripts to Jurnal Indo-Islamika are responsible for maintaining academic honesty, accurate attribution, and the originality of their scholarly contributions.

Authors are required to:

  • Submit original scholarly work that has not been plagiarized or improperly reproduced from previously published materials.
  • Provide accurate citations and use quotation marks or other appropriate conventions when reproducing the words of other authors.
  • Acknowledge the sources of intellectual ideas, theories, research findings, historical documents, translations, illustrations, and methodological contributions.
  • Ensure that the interpretation and presentation of Qur'anic texts, hadith materials, classical Islamic scholarship, and contemporary scholarly literature accurately distinguish original analysis from borrowed interpretations.
  • Disclose significant similarities with their own previously published works and avoid redundant or duplicate publication.
  • Verify the accuracy and authenticity of all citations, references, quotations, and source documentation.
  • Ensure that AI-assisted or translated material does not introduce unattributed copying, fabricated references, or misrepresented scholarly contributions.
  • Review similarity reports and undertake necessary corrections when required by the editorial office.
  • Respond accurately and cooperatively to editorial requests concerning manuscript originality, attribution, and publication ethics.

Authors should not attempt to reduce similarity scores through superficial changes, inappropriate paraphrasing, manipulation of text formatting, or other practices that conceal rather than resolve improper attribution.

Compliance with the Turnitin threshold is a necessary manuscript-screening requirement, but it does not replace the obligation to produce original scholarship, engage critically with existing literature, and acknowledge all relevant intellectual contributions.
