KOHESI : Jurnal Pendidikan Bahasa dan Sastra Indonesia does not accept manuscripts containing plagiarism, unattributed use of others' work, unauthorized reproduction, or improper attribution. Submitted manuscripts are screened using Turnitin plagiarism detection software, with an initial similarity threshold of 20%. Manuscripts exceeding this threshold may be subject to further assessment, revision, or rejection, depending on the nature and extent of the similarity. A similarity score alone does not automatically establish plagiarism. Editors assess the screening report in context, including source overlap, quotations, references, and attribution.

Authors are responsible for ensuring proper citation of all sources and obtaining permissions where required. Suspected plagiarism identified after publication will be investigated and may result in a correction, an expression of concern, or a retraction.
