Submissions

Author Guidelines

All submissions to the Journal must be in English and uploaded to the JCTA OJS, where previously, the Author had to register with OJS.

Manuscripts must be submitted as one Word file, including the full title of the article, author name, affiliation, and address, all text, figures, tables, references, etc. Each submitted paper must follow the margins, fonts, captions, and general formatting in the A4 template: (Template for MS Word).

For original research article submissions, the required text length is between 3,000 to 8,000 words, which roughly corresponds to 8 to 20 pages (without references). For review articles, the maximum length is about 30 pages (without references).

The author must be identified. He must also provide his postal address and email.

References must follow the IEEE style. We highly recommend preparing references with a bibliography software package like Mendeley, EndNote, or Zotero to avoid typos and duplicate references. Include digital object identifiers (DOIs) for all references where available. Doing a DOI-based lookup (if any) is important for the reference manager. Below is an example of a bibliography:

Before sending to review

We check for similarity using Turnitin (plagiarism). The paper will pass if the similarity is a maximum of 25%, excluding the bibliography. In addition, self-citation is not more than 25%.

We also check the suitability of the paper submission topic with the objectives and scope of the journal.

Revision Stage

The author must respond to the reviewer for revisions and/or rebuttal at the revision stage.
In addition, improvements must be marked with highlights, and the highlighted document files must be uploaded with the revised manuscript in the supplementary material for review.
The response template can be downloaded here.

After Acceptance

Corresponding authors must print the copyright form, signed by all authors, scan it, also must upload competing interests to the OJS in the Author Version or send to editorial.jcta@gmail.com.

Starting from MAY 2025, APC will be imposed for authors from Indonesia (except those with co-authors from abroad), the amount of APC is IDR 250,000.00. APC must be paid before the production process.

Withdrawal Policy

• Submitting a manuscript should not be done carelessly or without the knowledge of all involved parties. Submitting merely to obtain a review or as a trial is considered a violation of publication ethics and cannot be used as a reason for withdrawal.
• Manuscript withdrawal will be permitted only for the most compelling and unavoidable reasons. It is unacceptable to withdraw a manuscript from a journal because it has been accepted by another journal.
• Authors should submit a request to the editorial office as a letter signed by all authors, stating the full reasons that led to the decision to withdraw the manuscript.
• If the review process takes more than six months, the publisher allows the author to withdraw the manuscript without paying any charges.
• If the manuscript has already been accepted for publication, the author must pay a penalty of USD 100 per manuscript for withdrawal, as this compensates for the resources and time already invested by the journal.
• If the author does not agree to pay the penalty, the author and their affiliation will be blacklisted from publishing in this journal.
• Authors must not assume that their manuscript has been withdrawn until they have received appropriate notification to this effect from the editorial office.

Repository Policy

The journal allows authors to deposit versions of their work in institutional repositories, ResearchGate, or other repositories of their choice. Authors are encouraged to share their accepted manuscripts (post-print) or published versions, provided that proper credit is given to the journal, and the DOI link to the official version is included.

Retraction Policy
The Journal of Computing Theories and Applications (JCTA) is dedicated to upholding academic integrity and ensuring the reliability of published research. Articles may be retracted in cases where significant ethical violations or errors are identified after publication.

Reasons for Retraction:
1. Plagiarism or Duplication: The article contains substantial overlap with other works without proper attribution or has been published elsewhere without disclosure.
2. Data Issues: Fabricated, falsified, or manipulated data undermines the validity of the findings.
3. Ethical Violations: Breaches of ethical standards, such as unauthorized use of copyrighted materials or undisclosed conflicts of interest.
4. Critical Errors: Major methodological or analytical mistakes that invalidate the conclusions.

Retraction Process:
1. Investigation: The editorial team reviews complaints or identified issues. Authors are contacted and given an opportunity to respond.
2. Decision: Based on evidence, the editorial board decides whether to retract the article or issue a correction.
3. Retraction Notice: A notice is published explaining the reason for retraction. The original article remains accessible but is marked as "RETRACTED."

4. Post-retraction: The DOI of the original article remains active to ensure proper citation and traceability of the retraction.

Retractions are conducted in accordance with Committee on Publication Ethics (COPE) guidelines. Retraction notices are linked to the original article and indexed in relevant databases.

Authors responsible for ethical breaches may face consequences, including restrictions on future submissions and notifications to their institutions.
