Screening for Plagiarism Policy

Lingkar: Journal of Environmental Engineering is committed to the integrity of scholarly work. Every submission is screened for plagiarism before it goes to review, and plagiarism is handled under the Publication Ethics policy.

How Submissions Are Screened

Step What happens
Initial screening Each submitted article is checked with Turnitin for overlap with existing content, as part of the desk review by the designated editor.
Threshold To be considered, an article must have a similarity score below 20%. Articles above this limit are examined more closely.
Editorial evaluation The editor reads the similarity report, since a percentage alone is not a finding of plagiarism. Manuscripts that pass screening go on to review.
Minor similarities The authors are asked to revise the text so that sources are cited correctly and the wording is their own.
Significant plagiarism The submission is rejected immediately, and the case may affect the authors' eligibility to submit again (see the sanctions in Publication Ethics).

What Counts as Plagiarism

  • Direct copying: reproducing another author's work word for word without permission or acknowledgement.
  • Substantial copying: reproducing a notable part of another work, where “substantial” is judged by the value and extent of the copied content.
  • Paraphrasing without credit: restating another person's words or ideas without adequate attribution.

Plagiarism is more than copying: it presents someone else's thoughts, words, or findings as one's own. Authors confirm in the signed Author Statement Form that the manuscript is free of plagiarism and complies with this policy.
