Plagiarism Policies

 

1. Introduction

JISA (Jurnal Informatika dan Sains) is committed to maintaining academic integrity, originality, and ethical standards in scholarly publishing. Plagiarism and other forms of unattributed use of intellectual work undermine the reliability of academic research and are not acceptable in manuscripts submitted to or published by the journal.

All authors submitting manuscripts to JISA are responsible for ensuring that their work is original, that sources are properly acknowledged, and that any material taken from other sources is appropriately quoted, cited, or otherwise attributed.

2. Definition of Plagiarism

Plagiarism refers to the use of another person's words, ideas, research findings, data, images, or other intellectual contributions without appropriate acknowledgment. It may occur in submitted manuscripts or published articles and includes, but is not limited to:

  • Direct plagiarism: Reproducing text or other material from a source without appropriate quotation and citation.

  • Mosaic plagiarism: Combining phrases or passages from one or more sources without adequate attribution.

  • Paraphrasing without attribution: Rewriting another person's ideas or findings without citing the original source.

  • Data or image plagiarism: Using another person's data, figures, tables, images, or other research materials without appropriate acknowledgment or permission where required.

  • Self-plagiarism or redundant publication: Reusing substantial portions of one's previously published work without appropriate citation, disclosure, or justification.

The journal distinguishes plagiarism from legitimate quotation, properly cited reuse, and acceptable overlap in standard terminology or methodological descriptions. Each case is assessed according to its context and the nature of the material involved.

3. Similarity Screening

Manuscripts submitted to JISA are subject to similarity screening as part of the editorial assessment process. The journal may use Turnitin or another appropriate similarity-detection tool to identify text overlap with existing publications and other available sources.

Authors are encouraged to check their manuscripts for appropriate citation and attribution before submission. A similarity report is used as an aid to editorial assessment and does not, by itself, establish whether plagiarism has occurred.

Editors evaluate the report in context, considering the sources of overlap, the location and extent of matching text, citation practices, the nature of the material, and whether the overlap affects the originality or integrity of the manuscript.

4. Editorial Assessment

When a similarity report or other information raises concerns, the editor assesses the relevant passages and sources before deciding on the appropriate action.

Depending on the nature and seriousness of the concern, the journal may:

  • Request clarification or revision from the authors.

  • Ask the authors to provide proper citations, quotations, permissions, or supporting documentation where appropriate.

  • Reject a manuscript when plagiarism or unacceptable overlap is established.

  • Refer a serious or unresolved concern for further assessment in accordance with the journal's research misconduct procedures.

Editorial decisions are based on the available evidence, the context of the overlap, and the journal's publication ethics policies. The journal does not rely solely on a numerical similarity score to determine whether a manuscript contains plagiarism.

5. Similarity Scores and Editorial Decisions

JISA does not treat a single similarity percentage as a universal threshold for determining plagiarism. A high similarity score may result from references, standard terminology, properly quoted material, or other legitimate overlap. Conversely, a low score does not necessarily exclude plagiarism if unattributed material is identified.

The editorial team evaluates the content and context of the matching passages before determining whether further action is necessary. Any similarity thresholds used internally by the journal should be applied as screening guidance rather than as an automatic substitute for editorial judgment.

6. Responsibilities of Authors

Authors submitting manuscripts to JISA are expected to:

  • Submit original work that is not under consideration for publication elsewhere, except where the journal's policies explicitly permit and the circumstances are fully disclosed.

  • Cite the sources of ideas, methods, data, quotations, figures, tables, and other material derived from existing work.

  • Use quotation marks or other appropriate formatting when reproducing text verbatim.

  • Obtain permission for reused copyrighted material where required.

  • Disclose relevant overlap with their own previously published work.

  • Cooperate with reasonable editorial requests for clarification concerning originality, citations, and source attribution.

All listed authors share responsibility for ensuring that the submitted manuscript complies with the journal's publication ethics requirements.

7. Handling Suspected Plagiarism After Publication

If a concern about plagiarism is raised after an article has been published, JISA will assess the available evidence and determine whether further investigation or editorial action is appropriate.

Where necessary, the journal may contact the authors, consult independent experts, or refer the matter to a relevant institution or research organization. Depending on the findings and the seriousness of the case, possible actions may include a correction, an expression of concern, or retraction in accordance with the journal's Correction and Retraction Policy.

The journal seeks to handle such cases fairly, confidentially, and transparently while protecting the integrity of the scholarly record.
