All manuscripts submitted to Jurnal Ilmiah Berkala Sains dan Terapan Kimia undergo a rigorous peer-review process to ensure that published articles meet the journal’s academic and scientific standards. Manuscripts submitted to the journal must comply with the journal’s focus and scope as well as the author guidelines.

Each submitted manuscript is initially evaluated by the editorial team to assess its suitability for publication, including originality, scientific quality, relevance to the journal scope, and compliance with ethical standards. All manuscripts must be free from plagiarism. Authors are strongly encouraged to conduct similarity checking using plagiarism detection software prior to submission. The editorial team also performs plagiarism screening for all submitted manuscripts.

Manuscripts that pass the initial editorial evaluation are sent to at least two reviewers with relevant expertise in the corresponding field. The journal applies a blind peer-review process, and all submitted manuscripts are treated as confidential documents throughout the review process.

Reviewers are generally expected to complete their reviews within approximately two weeks after receiving the manuscript. Based on the reviewers’ comments and recommendations, the Editors will make the final decision regarding manuscript acceptance, revision, or rejection. Authors are responsible for revising their manuscripts according to the reviewers’ and editors’ suggestions before the manuscript can be accepted for publication.

The corresponding author will be notified of the editorial decision after the review process has been completed. All accepted manuscripts will proceed to the copyediting and publication stages before being published online.

JSTK utilizes the LOCKSS (Lots of Copies Keep Stuff Safe) system to ensure secure and permanent archiving of the journal content. LOCKSS is an open-source archiving system developed by Stanford University Library that enables libraries to preserve selected web journals by regularly collecting and storing newly published content.

The LOCKSS system creates distributed archival copies among participating libraries to ensure the long-term preservation and accessibility of journal content. Each archived file is continuously validated across the network, and in the event that any content is lost or corrupted, it can be restored from other archived copies within the system.

Plagiarism Policy

All manuscripts submitted to JSTK will undergo plagiarism screening using Turnitin. The maximum acceptable similarity index is 15%. Manuscripts exceeding this threshold may be rejected or returned to the authors for revision before entering the peer-review process.

Article Withdrawal Policy

Authors are not permitted to withdraw manuscripts that have already been submitted and entered the editorial or peer-review stages, except for reasonable and acceptable grounds approved by the Editors. Withdrawal requests without valid justification disrupt the editorial process and waste valuable editorial and reviewer resources.

If authors intentionally withdraw manuscripts during the editorial or review process without acceptable reasons, the authors will receive a publication penalty in the form of a submission ban from JSTK for at least three publication volumes (three years).

Retraction Policy

Published articles may be retracted if clear evidence is found regarding fabrication, falsification, plagiarism, duplicate publication, unethical research practices, or major errors that significantly affect the reliability of the published work.

If publication misconduct is confirmed, JSTK reserves the right to retract the article and publicly announce the retraction on the journal website. The retraction notice may include information regarding the article title, author(s), and the reasons for the retraction due to unethical publication practices.

Authors who use artificial intelligence (AI) or AI-assisted technologies in manuscript preparation for permitted purposes must clearly disclose such use in a dedicated section entitled “Declaration of AI Use in Manuscript Preparation” within the manuscript.

Any use of AI technologies in manuscript preparation should be disclosed appropriately by the authors when necessary. AI tools or software cannot be listed as authors or co-authors because they cannot take responsibility for the submitted work.

The Editors of JSTK reserve the right to reject manuscripts containing unethical or inappropriate use of artificial intelligence technologies that violate publication ethics and scientific integrity principles.
