Publication Ethics

Lingkar: Journal of Environmental Engineering publishes research that can be trusted. Authors, reviewers, editors, and the publisher share this responsibility, and the journal follows the principles of COPE (Committee on Publication Ethics). This page explains what each role commits to and how Lingkar checks it.

What Is Distinctive at Lingkar

Safeguard How it works
Signed Author Statement Form The corresponding author signs, on behalf of all authors, a declaration on originality, authorship, conflicts of interest, research ethics, generative AI use, and compliance with the Author Guidelines. A submission without it is returned before review.
Double-blind review, prepared by the journal Authors submit with their names; the editorial office prepares the anonymised file. Two reviewers assess the whole manuscript and never learn the authors' identities.
Verified references At least 20 references, of which at least 75% are articles in reputable journals. Entries that cannot be verified are not counted, and fabricated references are misconduct.
Mandatory AI Writing Statement Every manuscript declares its use of generative AI, or its non-use. See the Generative AI Policy.
Similarity screening Every submission is screened with Turnitin by the designated editor before review (see Screening for Plagiarism Policy).

Authors

  • The manuscript is original, is not under consideration elsewhere, and is not a translation. Duplicate or salami publication is not accepted.
  • Data are real. Fabricating, falsifying, selectively reporting, or manipulating data, graphs, images, or charts is data falsification.
  • Research that involves people or sensitive environmental data has the required ethical approval, and its number is given in the Author Statement Form and the manuscript.
  • Every source is credited, and permission is held for any third-party material. Authorship follows the Authorship Policy.
  • Any conflict of interest, funding, or competing interest is declared, whether or not it influenced the work.

Reviewers

  • Manuscripts are confidential. Reviewers do not share them, use them for personal benefit, or upload them to AI tools or any external service.
  • Reviews are objective and constructive, follow the Reviewer Guidelines, and contain no personal remarks.
  • A reviewer who has a conflict of interest, or who cannot review on time, informs the editorial office at once. Close competitors should decline.

Editors

  • Decisions rest on the work's validity, originality, significance, and fit with the scope, together with the journal's policies and the reviewers' reports. Authors' race, gender, beliefs, or affiliations play no part (fair play).
  • Commercial interests, such as advertising or reprints, do not influence editorial decisions, and payment of the publication fee never precedes or influences a decision.
  • Editors withdraw from any manuscript in which they have a conflict of interest, and they keep manuscripts and reviewer reports confidential.

When Something Goes Wrong

Suspected misconduct is investigated confidentially, as described in Allegations of Research Misconduct, which also lists the sanctions the journal may apply. Conflicts of interest are covered by the Conflict of Interest Policy. Concerns about a published article are handled under Post-publication Discussion and the Correction and Retraction Policy.
