Dear Authors,

Universitas Ahmad Dahlan (UAD) are committed to upholding the highest standards of academic integrity and publishing ethics. To ensure transparency, fairness, and responsible dissemination of research, we require all authors to adhere to the following policy regarding multiple submissions and prior publication:

Originality and Prior Publication

• Manuscripts submitted to TELKOMNIKA journals must be original, unpublished, and not under consideration elsewhere.
• Work that has been previously published in any form—including journal articles, conference proceedings, preprints with DOI, book chapters, or institutional repositories—must be clearly disclosed at the time of submission.
• Authors must ensure that their manuscript does not substantially overlap with previously published or submitted work unless explicitly justified and approved by the editorial office.

Simultaneous Submissions

• Submitting the same manuscript to more than one journal or conference simultaneously is strictly prohibited.
• Simultaneous submissions can lead to copyright conflicts, duplication of editorial and peer review efforts, and confusion in citation and indexing systems.
• UAD reserve the right to reject manuscripts found to be under concurrent review elsewhere, even if discovered post-submission.

Redundant and Duplicate Publication

• Redundant publication (publishing substantially similar content in multiple venues) undermines the integrity of scholarly communication.
• Authors must avoid submitting incremental or overlapping versions of the same research without clear differentiation and editorial approval.
• If a manuscript builds upon prior work (e.g., extended conference papers), authors must:
  • Clearly cite the original source.
  • Provide a detailed explanation of the novel contributions.
  • Submit the prior version as supplementary material for editorial review.

Consequences of Violations

Authors who violate this policy may be subject to the following actions:

1. Formal Warning: Notification of unethical scholarly conduct.
2. Written Apology: A formal apology addressed to the editorial board.
3. Publication Ban: Suspension from submitting to TELKOMNIKA journal for a period of up to one year.
4. Retraction: If the manuscript has already been published, it may be retracted with public notice.

Repeat or severe violations may result in notification to the authors’ institutions or funding bodies, in accordance with COPE (Committee on Publication Ethics) guidelines.

Author Responsibility

Authors are responsible for:

• Ensuring the integrity and originality of their submissions.
• Disclosing any prior dissemination of the work.
• Communicating transparently with editors regarding related submissions or publications.

Your cooperation is essential in maintaining the quality and credibility of our publications. We appreciate your commitment to ethical research and scholarly excellence.

Best regards,
Editor-in-Chief, TELKOMNIKA
