Plagiarism Policy

Didaktika Biologi: Jurnal Penelitian Pendidikan Biologi is committed to maintaining academic integrity and preventing plagiarism in scholarly publishing. All submitted manuscripts must represent original work and appropriately acknowledge the ideas, words, data, and contributions of other sources.

1. Definition of Plagiarism

Plagiarism refers to the use of another person's ideas, words, data, findings, or other intellectual contributions without proper acknowledgment or appropriate citation. It includes, but is not limited to:

• Copying text or passages from other sources without proper citation.
• Paraphrasing another author's ideas without acknowledging the original source.
• Presenting another person's data, results, or research findings as one's own.
• Reusing substantial parts of one's previously published work without appropriate citation or disclosure (self-plagiarism).
• Submitting manuscripts or substantial portions of work written by others as one's own.

2. Similarity Screening

All submitted manuscripts are subject to similarity screening using plagiarism detection software as part of the initial editorial assessment.

The journal establishes a maximum similarity index of less than 25% (similarity index < 25%) for submitted manuscripts.

Manuscripts that do not meet this requirement may be returned to authors for revision or rejected, depending on the nature and extent of the identified similarities.

The similarity index is used as an initial screening indicator and does not automatically determine whether plagiarism has occurred. Editors examine the similarity report to assess the sources and context of matching text, including quotations, references, commonly used terminology, and other legitimate similarities.

3. Editorial Assessment

The editorial team reviews similarity reports to identify potential cases of plagiarism and inappropriate text reuse. Editorial assessment considers:

• The percentage and distribution of similarity across the manuscript.
• The sources of matching text.
• The use of quotations, citations, and references.
• The originality of the research and its presentation.
• Any indication of unattributed copying or inappropriate reuse of published work.

The editor may request clarification or manuscript revision when necessary. Suspected plagiarism is evaluated based on the evidence and the seriousness of the identified concerns.

4. Actions in Cases of Plagiarism

If plagiarism or inappropriate text reuse is identified, the journal may take one or more of the following actions, depending on the severity of the case:

• Request clarification or correction from the author.
• Return the manuscript for substantial revision.
• Reject the submitted manuscript.
• Initiate further investigation in accordance with the journal's Research Misconduct Policy.
• Take post-publication action, including correction or retraction, when necessary.

5. Authors' Responsibilities

Authors are responsible for ensuring that their manuscripts are original, properly cited, and free from plagiarism. Authors must:

• Provide accurate citations and references for all sources used.
• Use quotation marks and appropriate citations when reproducing text from other sources.
• Paraphrase ideas appropriately while acknowledging the original authors.
• Disclose relevant reuse of their previously published work.
• Ensure that submitted manuscripts comply with the journal's similarity requirements.
