Plagiarism Screening

JISPO screens every submission using the Turnitin similarity-detection system. Manuscripts showing indications of plagiarism or self-plagiarism will be rejected, and those with an overall similarity exceeding 20% are normally returned or declined prior to review. If a breach is discovered after acceptance or publication, the editorial team may withdraw acceptance, issue a correction or retraction, and notify relevant parties.

JISPO upholds international standards of academic integrity. Plagiarism occurs when ideas, information, or wording from another source are used without proper acknowledgment. This includes unattributed paraphrase and the reuse of one’s own previously published text (self-plagiarism). Intent does not remove responsibility: even unintentional plagiarism is a serious violation and is unacceptable.

Authors must cite a source whenever specific information (e.g., names, dates, places, statistics, distinctive arguments) is taken from that source. Citation is not required for common knowledge—widely available facts that can be found in many standard references (for example, that Indonesia has the world’s largest Muslim population).

When authors adopt or build upon another scholar’s idea—such as a theoretical insight, methodological approach, or interpretive claim—the original source must be cited, even if the author extends or modifies that idea in the manuscript. The author may then explain how their work develops the argument further.

When authors reproduce another author’s exact words, both a citation and quotation marks are required. As a rule of thumb, if four or more consecutive words replicate a source, quotation marks must be used; a citation alone is insufficient. Paraphrasing must be genuinely written in the author’s own words and structure, accompanied by a citation to the source.
JISPO treats academic integrity with the utmost seriousness. The editors reserve the right to decline, withdraw, correct, or retract any work that violates these standards.
