Authors keep the copyright in their articles. JETS does not ask authors to transfer copyright to the journal or to Institut Teknologi Bandung.

When an article is accepted, the authors grant JETS a non-exclusive licence to publish it first, to identify itself as the original publisher, to assign a DOI, and to distribute and archive the article and its metadata, including through indexing services and preservation networks.

Where the copyright belongs to the authors' employer, for example a government agency or company, the corresponding author must confirm that the employer has agreed to publication on these terms.

All JETS articles are published open access under the Creative Commons Attribution 4.0 International licence (CC BY 4.0).

https://creativecommons.org/licenses/by/4.0/

This means an article can be deposited in repositories, used in teaching, included in textbooks, translated, or mined as text and data, without asking permission from the authors or the journal. The licence and copyright holder are stated on the first page of every article and on its web page.

Online access: Articles are free to read on publication. There is no embargo and no subscription or registration barrier for online access.

In every case, the published version should be cited with its DOI. Reusing a substantial amount of text from a published JETS article in a new journal article is text recycling and must be acknowledged. It is covered in Section 7.

Authors must hold the right to publish everything in their manuscript under the journal's licence.

Where a manuscript includes material created by someone else, the authors must either obtain written permission from the rights holder or rely on a legal exception, and must credit the source in the caption or text.

Important: Redrawing a figure does not remove the need for permission if it reproduces the substance of the original. Creating a new figure from data that has been published is usually acceptable, provided the data source is cited.

Rights holders sometimes grant permission only for print, only for subscription publication, or only for non-commercial use. Such permission is not enough for an open access article published under the journal's licence.

Authors must keep copies of all permissions and supply them if the editors ask.

Publishing an invention in JETS, or posting it as a preprint, makes it public. In most countries, public disclosure before a patent application is filed can prevent the invention from being patented.

Authors who wish to protect an invention described in their manuscript should file a patent application before submitting to JETS or posting a preprint, and should consult their institution's intellectual property or technology transfer office.

Important: Journal review is confidential, but submission is not a substitute for filing. JETS cannot delay publication of an accepted article to allow a patent application to be filed.

Patents and pending applications related to the work must be declared as competing interests, as described in the JETS Conflicts of Interest policy.

Engineering research often uses information that belongs to a company, client or government body, such as process parameters, design details, operating data or test reports.

Authors must not include such information in a manuscript unless the owner has given permission to publish it. Permission must cover publication under an open licence, because once published the information can be freely copied.

Where permission is limited, authors should anonymise, normalise or aggregate the information, as described in the JETS Data and Reproducibility policy.

Authors remain responsible for any breach of a confidentiality agreement.

Manuscripts submitted to JETS must be original, not previously published in a journal, and not under consideration elsewhere.

A full paper already published in conference proceedings may be considered only if the JETS manuscript is a substantially extended version, with significant new results, analysis or discussion, and cites the proceedings paper.

The editors decide whether the extension is sufficient.

Reusing a limited amount of text from one's own earlier work can be acceptable if the source is cited. Reusing results, figures, discussion or conclusions without clear disclosure is redundant publication.

All submissions are screened for similarity with published work, as described in the JETS Publication Ethics and Plagiarism Policy.

Supplementary files published with an article on the JETS website are covered by the article's licence unless stated otherwise.

Data and code deposited by authors in external repositories may carry their own licences.

The chosen licence should be stated in the repository and in the Data Availability Statement.

Reviewers keep the copyright in their reports. Reports are treated as confidential and are shared only with the editors and the authors of the manuscript concerned.

JETS does not publish review reports or reviewers' names without the reviewer's explicit consent.

Reviewers must not use, share or disclose any part of a manuscript under review, and must not upload it to generative AI tools or other third-party services.

The name "Journal of Engineering and Technological Sciences" , the abbreviation "JETS" in connection with the journal, and the journal's logo and cover designs belong to Institut Teknologi Bandung.

They may not be used to suggest endorsement, or in connection with other publications, events or services, without written permission.

JETS does not use agents to solicit submissions and does not offer guaranteed publication.

Websites, emails or conferences that claim to publish in JETS on behalf of authors, or that imitate the journal's website, are not associated with it.

Please report them to jets@itb.ac.id .

If you believe that a JETS article infringes your copyright or other rights, or includes your material without permission, please write to:

Please provide details of the article, the material concerned and your rights in it.

Serious or deliberate infringement is handled under the JETS policy on allegations of misconduct.
