Jurnal Ilmiah Metadata is committed to upholding the highest standards of academic integrity and publication ethics. The journal strictly prohibits all forms of plagiarism and only publishes original scholarly works that have not been previously published or submitted simultaneously to another journal. Plagiarism is defined as the use of another person's ideas, words, data, figures, methods, or research findings without proper acknowledgment or citation. Likewise, self-plagiarism, duplicate publication, and redundant publication are considered unethical publishing practices and are not acceptable.

Types of Plagiarism

The journal recognizes several forms of plagiarism, including but not limited to:

1. Full Plagiarism

Presenting another person's work, ideas, data, or text in its entirety as one's own without appropriate citation or permission.

2. Partial Plagiarism

Reproducing substantial portions of another author's work through paraphrasing, modification, or selective copying without proper attribution.

3. Self-Plagiarism

Reusing significant portions of one's own previously published work without appropriate citation, including duplicate publication, redundant publication, or submitting substantially similar manuscripts to different journals.

Author Responsibilities

Authors submitting manuscripts to Jurnal Ilmiah Metadata must ensure that:

• The manuscript is an original work.
• All sources of information, data, figures, tables, and ideas have been properly cited.
• Any quotations are clearly identified and appropriately referenced.
• The manuscript has not been published previously and is not under consideration by another journal.
• Appropriate acknowledgment has been given to all contributors and previous relevant publications.
• Any use of copyrighted material has obtained the necessary permissions.

Submitting the same or substantially similar manuscript to more than one journal simultaneously constitutes unethical publication behavior and is strictly prohibited.

Similarity Screening

All manuscripts submitted to Jurnal Ilmiah Metadata undergo a plagiarism screening before entering the peer-review process using trusted similarity detection software such as Turnitin and/or other equivalent plagiarism detection tools. The Editorial Office evaluates the similarity report carefully to distinguish between acceptable textual similarity (such as references, methodology descriptions, or standard terminology) and actual plagiarism. As a general policy:

• The maximum acceptable similarity index is 24%.
• Similarity arising from references, properly quoted text, standard methodological descriptions, or commonly used technical terminology will be evaluated at the Editor's discretion.
• Manuscripts showing evidence of plagiarism, duplicate publication, data fabrication, or other forms of academic misconduct may be rejected immediately without being sent for peer review.

If plagiarism is identified after publication, the Editorial Board reserves the right to take appropriate corrective actions, including issuing corrections, publishing expressions of concern, retracting the article, and notifying the authors' affiliated institutions when necessary.

Editorial Responsibility

Editors reserve the right to reject any manuscript that violates this plagiarism policy. Decisions are made based on the overall assessment of the similarity report, editorial evaluation, and the principles of publication ethics. Jurnal Ilmiah Metadata follows the ethical guidelines and recommendations of the Committee on Publication Ethics (COPE) in handling cases involving plagiarism, duplicate publication, and other forms of publication misconduct.
