Plagiarism Policy

Hasanuddin Journal of Animal Science (HAJAS) does not tolerate plagiarism or inappropriate overlap with other work. Authors must guarantee that the work is their own and that the work and words of others are properly cited or quoted. Authors are responsible for acknowledging all words, ideas, data, figures, and other contributions taken from others.

What counts as plagiarism

• Taking all or part of another person’s work, including text, data, ideas, tables, or figures, without citing the source properly.
• Rewriting another person’s work without using one’s own words, even if the source is cited.
• Reusing one’s own published work, in whole or in part, without proper citation (text recycling or self-plagiarism).
• Submitting the same work, or a substantially similar one, that is already published or under consideration elsewhere (see Publication Ethics).

How plagiarism is identified

Every manuscript is screened with Turnitin at submission and again after revision. A similarity report is not a verdict. The percentage alone is only an indication and is not proof of plagiarism. The editors read the report and look at the nature, source, size, and location of each overlap, whether it is attributed, and its scholarly context. A significant overlap, or a large overlap within a single block of text that traces to one particular work and is not presented as a direct quotation, is treated as an indication of plagiarism. Correctly quoted text and reference lists are not counted against the authors.

Similarity threshold

If the similarity exceeds 25%, the authors must rewrite the affected text. A manuscript whose similarity cannot be reduced below this level is not published.

Classification and action

• Minor overlap, for example incomplete paraphrasing in a few sentences: the authors are asked to revise the text.
• Substantial overlap or plagiarism of data, ideas, or text: the manuscript is rejected, and the authors may be barred from submitting for a defined period.
• Plagiarism found after publication: the case is handled under the Corrections, Retractions and Post-Publication Discussion policy. The article may receive a correction, expression of concern, or retraction, and the authors’ institution may be informed.

The authors are always given a chance to respond before a decision is made. Cases follow the procedure for allegations of misconduct on the Publication Ethics page.
