Plagiarism Policy

All manuscripts submitted to al Kimiya: Jurnal Ilmu Kimia dan Terapan are subject to originality assessment. The editorial office uses Turnitin and/or other appropriate scholarly checks to identify textual overlap, possible unattributed reuse, duplicate submission, and problematic citation practices.

How Screening Results Are Interpreted

A similarity percentage is a screening indicator, not a standalone measure of plagiarism. Editors consider the location and nature of matched material, quotation and citation practices, overlap in methods, authorized preprints, the reuse of an author's previous work, and evidence of substantial intellectual or data duplication. A manuscript with a low similarity score may still contain serious plagiarism, and a higher score may sometimes be explainable.

The journal does not automatically classify every manuscript above an arbitrarily stated percentage as research misconduct. Where material overlap is excessive or inadequately attributed, editors may request clarification or revision, reject the submission, or initiate a formal ethics review.

Forms of Unacceptable Practices

• Copying text, figures, tables, chemical structures, datasets, images, or original ideas without appropriate attribution or permission.
• Self-plagiarism or redundant publication of substantial portions of a previously disseminated work without transparent citation and editorial disclosure.
• Fabrication or falsification of sources, references, experimental data, or images.
• Translating and republishing material without proper disclosure, permissions, or a legitimate editorial basis.
• Deliberately concealing overlap or simultaneous submission to another journal.

Authors must cite relevant source literature and obtain permission for third-party copyrighted materials when necessary. Manuscripts presenting potential misconduct will be handled under the Research Misconduct Policy and the journal's post-publication correction procedures.

Note: A similarity threshold stated in an individual, historic conference agreement should not automatically be treated as a standing journal-wide rule.
