Authorship Criteria

Jurnal Teknik Kimia dan Lingkungan (JTKL) is committed to upholding the principles of responsible authorship, transparency, accountability, and publication ethics in accordance with the guidance of the Committee on Publication Ethics (COPE). Authorship acknowledges significant scholarly contributions to a research publication and entails responsibility for the accuracy, originality, and integrity of the reported work. All authors are expected to comply with these principles throughout the submission, peer-review, and publication processes.

1. Requirements for Authorship
In accordance with established principles of responsible authorship, an individual may be listed as an author only if they meet all four of the following criteria:
- Make a substantial contribution to the conception or design of the research, or to the acquisition, analysis, or interpretation of research data.
- Participate in drafting the manuscript or critically revising it for significant intellectual content.
- Approve the final version of the manuscript for publication.
- Agree to be accountable for their contributions and cooperate in ensuring that questions concerning the accuracy or integrity of any part of the work are appropriately investigated and resolved.

All individuals who meet these criteria should be included in the author list. Contributors who have made substantial intellectual contributions should be given the opportunity to participate in manuscript preparation or critical revision, provide final approval, and accept accountability before the manuscript is submitted.

2. Contributions That Do Not Qualify for Authorship

Consistent with COPE's principles of transparent authorship and contributorship, individuals who have contributed to a study but do not meet all the authorship criteria should not be listed as authors solely on the basis of their involvement.
Such contributions may be acknowledged in the Acknowledgments section, with the individual's consent. Examples include:
- Routine technical assistance, laboratory work, administrative support, or data collection without substantial intellectual involvement.
- Provision of funding, research facilities, equipment, materials, or other resources without significant intellectual contribution.
- General supervision or managerial responsibilities without substantial involvement in the research design, analysis, interpretation, or intellectual development of the manuscript.
- Language editing, proofreading, or formatting assistance that does not involve substantial intellectual contributions.

Acknowledgments must accurately describe the nature of the contribution and must not be used to justify honorary authorship or conceal contributions that warrant authorship.

3. Unacceptable Authorship Practices

JTKL does not accept practices that misrepresent the contributions or responsibilities of individuals involved in research. In line with publication ethics principles promoted by COPE, the following practices are unacceptable:
- Ghost authorship: Omitting individuals who have made qualifying contributions to the research and manuscript.
- Gift, guest, or honorary authorship: Including individuals who do not meet the authorship criteria, regardless of their academic position, seniority, reputation, or institutional authority.
- Coercive authorship: Requiring individuals to include another person as an author without a legitimate scholarly contribution.
- Purchased or traded authorship: Buying, selling, exchanging, or transferring authorship positions without genuine scholarly contributions.

Suspected authorship misconduct may be investigated in accordance with JTKL's publication ethics policies. Depending on the findings and the stage of publication, appropriate action may include requesting clarification, suspending editorial processing, rejecting the manuscript, or taking corrective action for a published article.

4. Corresponding Author

Each manuscript must designate a corresponding author who acts as the primary contact between the authors and the JTKL editorial office. The corresponding author must provide an active email address and a valid telephone or WhatsApp number.

The corresponding author is responsible for:
- Managing communication with the journal during submission, peer review, revision, and post-publication processes.
- Confirming that all listed authors meet the established authorship criteria.
- Ensuring that all authors have reviewed and approved the submitted manuscript and its final version.
- Confirming that all authors agree on the author list, the order of authors, and the designation of the corresponding author.
- Ensuring that the author contribution statement and other required declarations are accurate and complete.
- Submitting the manuscript through the journal's Online Journal System (OJS) in accordance with the author guidelines.

The corresponding author must keep all co-authors informed of significant communications and editorial decisions. However, the corresponding author's role does not exempt other authors from their individual responsibilities for the integrity of the work.

5. Author Contribution Statement

JTKL requires every manuscript to include an Author Contribution Statement describing the contributions of each author. The journal encourages the use of the Contributor Roles Taxonomy (CRediT) to improve transparency and clarify individual responsibilities.

Contributions should be identified using the authors' initials and appropriate CRediT roles, such as Conceptualization, Methodology, Investigation, Data Curation, Formal Analysis, Software, Validation, Visualization, Writing – Original Draft, Writing – Review & Editing, Supervision, Project Administration, and Funding Acquisition.

For example:
Author Contributions: AB: Conceptualization, Methodology, and Investigation; CD: Data Curation, Formal Analysis, and Visualization; EF: Writing – Original Draft; GH: Writing – Review & Editing and Supervision. All authors reviewed and approved the final version of the manuscript.

The statement must accurately represent each author's contribution. Consistent with the principles of authorship and contributorship, assigning a CRediT role does not automatically qualify an individual for authorship; all four authorship criteria must still be satisfied.

6. Changes to the Author List or Author Order

Requests to add or remove an author or change the order of authors after submission must be submitted in writing by the corresponding author to the Editor-in-Chief, with a clear explanation of the reasons for the proposed change.

The request must include:
- A written justification for the proposed change.
- Written agreement from all authors, including any individual being added or removed.
- An updated author contribution statement reflecting the revised authorship arrangements.

The editorial team will assess the request in accordance with publication ethics principles and may request additional information when necessary. JTKL reserves the right to suspend editorial processing or delay publication until the request has been adequately reviewed and all required approvals have been obtained.

Changes to authorship after publication will be assessed on a case-by-case basis and handled in accordance with the journal's policies on corrections and publication ethics.

7. Authorship Disputes

In accordance with COPE's guidance on authorship disputes, authors are primarily responsible for determining authorship eligibility and agreeing on the order of authors. The journal does not independently determine individual authorship rights when the parties involved disagree about their contributions.

When a dispute arises, JTKL will assess the information available and may request written explanations, contribution records, or other relevant documentation from the parties involved. Where appropriate, the journal may refer the matter to the authors' affiliated institutions for investigation and clarification.

The editorial process may be suspended while the dispute remains unresolved. JTKL will consider the available evidence and any relevant institutional findings before determining whether further editorial action is necessary.

8. Use of Artificial Intelligence (AI) Tools

In accordance with COPE's position on authorship and AI tools, artificial intelligence systems, including generative AI tools, cannot be listed as authors or co-authors because they cannot assume responsibility for the accuracy, integrity, and ethical compliance of a scientific publication.

Authors who use AI tools in preparing a manuscript, generating images or graphical elements, or collecting or analyzing research data must disclose such use transparently in the relevant section of the manuscript, such as Materials and Methods or another appropriate section, in accordance with the journal's AI policy.

The disclosure should identify the AI tool used and explain its role in the research or manuscript preparation process. Authors remain fully responsible for verifying the accuracy of AI-assisted content, the validity of references and citations, and the originality and integrity of the submitted work.

AI tools must not be treated as substitutes for authors' intellectual contributions or professional judgment. Any suspected misuse of AI, including fabricated references, misleading content, or undisclosed AI-generated material that compromises research integrity, may be handled under JTKL's publication ethics policies.

9. Compliance with Publication Ethics

By submitting a manuscript to JTKL, all authors confirm that the author list accurately reflects their contributions, that all listed authors have approved the submitted version, and that they accept responsibility for the integrity of the work.

Any suspected violation of this policy will be assessed fairly and confidentially, following applicable publication ethics principles and relevant COPE guidance. Depending on the circumstances, the journal may request clarification, consult independent experts, contact the authors' affiliated institutions, reject the manuscript, or issue a correction or retraction if concerns arise after publication.

JTKL is committed to maintaining an ethical and transparent authorship process that recognizes legitimate scholarly contributions, prevents authorship manipulation, and protects the reliability of the scientific record.
