Plagiarism, Correction and Retraction Policy

Plagiarism Policy

Jurnal Indiktika is committed to upholding the highest standards of academic integrity, originality, and ethical publishing. The journal takes plagiarism and other forms of research misconduct seriously and is committed to ensuring that all published articles meet established standards of scholarly ethics.

Plagiarism occurs when authors use another person's words, ideas, data, findings, or other intellectual contributions without appropriate acknowledgment or citation. Plagiarism includes, but is not limited to:

Directly copying text from other sources without proper quotation and citation.
Paraphrasing or rephrasing another person's work without appropriate acknowledgment.
Using ideas, data, figures, tables, or research findings from other sources without proper citation.
Presenting another person's work as one's own.
Reusing substantial portions of one's previously published work without proper acknowledgment (self-plagiarism).

Similarity Index

All manuscripts submitted to Jurnal Indiktika may be screened for similarity using plagiarism detection software, such as Turnitin. The journal applies a maximum similarity index of 20%, excluding properly identified references, quotations, and other legitimate matches where applicable.

The similarity index is used as an initial screening indicator and does not, by itself, determine whether plagiarism has occurred. Each similarity report will be evaluated by the editorial team to assess the nature, source, and context of the detected similarities.

Manuscripts that exceed the journal's similarity threshold or contain indications of plagiarism may be returned to the authors for clarification or revision, or rejected, depending on the severity of the findings and the journal's editorial judgment.

Plagiarism Screening Process

Initial Screening: Submitted manuscripts are screened for similarity before or during the editorial assessment process.
Similarity Assessment: The editorial team examines the similarity report, considering the sources matched, the extent of overlap, the accuracy of citations, and the originality of the manuscript.
Editorial Decision: Manuscripts that meet the journal's originality and ethical standards may proceed to peer review. Manuscripts with substantial or inappropriate similarities may be returned for revision or rejected.
Further Investigation: If potential plagiarism or other research misconduct is identified, the journal may request an explanation from the authors and conduct further assessment before making a decision.

Consequences of Plagiarism

If plagiarism is identified during submission, peer review, or after publication, Jurnal Indiktika will take appropriate action based on the seriousness of the case and the available evidence. Possible actions include:

Manuscript Rejection: A manuscript may be rejected if plagiarism is confirmed during the submission or review process.
Request for Correction: Authors may be asked to correct citation errors or other inappropriate similarities when the issue is minor and can be appropriately resolved.
Retraction: If serious plagiarism is confirmed after publication, the journal may retract the article in accordance with its retraction policy and publication ethics procedures.
Notification of Relevant Institutions: Where appropriate and justified, the journal may notify the authors' affiliated institutions or other relevant parties.
Author Notification: The corresponding author will be informed of the editorial decision and, where appropriate, provided with relevant evidence or a similarity report.

All allegations of plagiarism will be assessed fairly and confidentially. Authors will be given an opportunity to respond to allegations before a final decision is made, where appropriate.

Correction

A correction may be issued when an error is identified in a published article that affects the accuracy, clarity, or completeness of the publication but does not invalidate its main findings or conclusions.

Requests for corrections may be submitted by authors, readers, reviewers, or other relevant parties. All requests will be assessed by the editorial team to determine the nature and significance of the error and the appropriate action.

Corrections may include, but are not limited to:

Errors in author names, affiliations, or other publication details.
Typographical, formatting, or factual errors that affect the interpretation or accuracy of the article.
Errors in tables, figures, references, or other published information.
Other inaccuracies that can be corrected without undermining the validity of the research findings.

When a correction is approved, Jurnal Indiktika will publish a correction notice describing the error and the changes made. The correction notice will be linked to the original article to ensure transparency and traceability. The original article will remain available, with appropriate links to the correction notice, unless further action is necessary.

Minor typographical errors that do not affect the meaning or interpretation of the article may be corrected without a separate formal correction notice, where appropriate.
