We operate Turnitin for similarity index checking process. Rekayasa Sipil apply Zero Tolerance towards plagiarism and therefore establishes the following policy stating specific actions (penalties) when plagiarism is identified in an article that is submitted for publication in Rekayasa Sipil.

Definition: Plagiarism involves the "use or close imitation of the language and throughts of another author and the representation of them as one's own original work."

Policy: Papers must be original, unpublished, and do not pending publication elsewhere. Any material taken from another source needs to be clearly identified as different from the present original text by indentation.

Any text of an amount exceeding fair use standards (herein defined as more than two or three sentences or the equivalent thereof) or any graphic material reproduced from another source requires premission from the copyright holder and if feasible, the original  author(s) and also requires identification of the source, e.g., previous publication.

Editorial board has passed the following actions:

• Similarity index above 40%: Article rejected (due to poor citation and/or poor paraphrasing, article outright rejected and no re-submission accepted)
• Similarity index 20 - 40%: Send to the author for improvement (provide correct citations to all places of similarity and arrange good paraphrasing even if the citation is provided)
• Similarity index less than 20%: Article accepted for the next step of publication.
