The Jurnal Lemhannas RI (JLRI) upholds the highest standards of academic integrity and firmly rejects all forms of plagiarism. This policy is fully aligned with the Regulation of the Minister of Education, Culture, Research, and Technology of the Republic of Indonesia Number 39 of 2021 on Academic Integrity in Scientific Publications, which provides a national legal framework for conducting ethical research. In addition, JLRI adheres to the international ethical standards established by the Committee on Publication Ethics (COPE).

All authors who submit manuscripts to JLRI must ensure that their work is completely original. The author are expected to avoid any form of plagiarism, falsification, fabrication, or unauthorised reuse of content previously published. Authors hold full responsibility for ensuring that every external source, whether quoted directly or paraphrased, is properly and accurately cited. This requirement applies to all types of references, regardless of whether they are published, unpublished, or in digital format.

To uphold this commitment, JLRI screens all submitted manuscripts using Turnitin or similar detection software. Manuscripts must not exceed a similarity index of twenty percent. If the similarity score exceeds this threshold, the editorial board will either return the manuscript for revision or reject it outright, depending on the nature and extent of duplication.

Plagiarism is defined as presenting another individual’s ideas, data, or text as one’s own without appropriate acknowledgement. This includes self-plagiarism, which refers to the substantial reuse of the author’s own previously published work without citation. JLRI classifies plagiarism into three levels of severity and responds to each with appropriate editorial measures.

When minor plagiarism is detected, which may involve a few sentences or a short paragraph lacking citation and containing no critical data or findings, the editorial board will issue a formal warning and request that the manuscript be revised with proper references.

Moderate plagiarism occurs when a significant portion of text, data interpretation, or analytical content is included without attribution. This results in the immediate rejection of the manuscript.

Severe plagiarism involves the extensive replication of content from previous publications, including data sets, conceptual frameworks, findings, or methodologies, without proper citation. In such cases, JLRI rejects the manuscript and prohibits the author from submitting future work. Where necessary, the editorial board may refer the case to the author’s affiliated institution for further review.

JLRI enforces this policy in accordance with the core principles set out in Ministerial Regulation Number 39 of 2021, which emphasises honesty, fairness, transparency, and accountability in scientific publication. The regulation identifies several forms of misconduct, including plagiarism, data falsification or fabrication, redundant or duplicate publication, authorship manipulation, and citation manipulation. If any of these violations are confirmed, JLRI may apply appropriate sanctions, including:

1. Rejection or withdrawal of the manuscript
2. Permanent blacklisting of the author from future submissions.
3. Formal notification to the author’s affiliated institution or relevant regulatory body, such as the Ministry of Education or a professional ethics board.
4. In cases of serious or repeated misconduct, JLRI may also recommend institutional action in accordance with applicable laws and regulations.
