Dear Authors and Prospective Authors,

We would like to inform you that since 28 October 2026, Jurnal Optimasi Sistem Industri (JOSI) has experienced a serious technical problem with its server. As a result, the JOSI website has been largely inaccessible since then.

Current status

Our team is now completing the final stage of the recovery, and we expect the website to be working normally again next week. Until then, some features, such as logging in, submitting a manuscript, or checking manuscript status, may not be available.

For authors with manuscripts in the editorial process

• The editorial process of your manuscript has not stopped. During the recovery period, the editorial team continues to handle all manuscripts manually and communicates with authors by email.
• Once the website is working normally, the progress of each manuscript will be updated in the JOSI system step by step.
• Please do not submit your manuscript again as a new submission. If we need any files or information from you, we will contact you by email.
• If a revision deadline falls within this period, please contact us. No author will be disadvantaged by delays caused by this disruption.

For prospective authors

New submissions will be welcomed again as soon as the online submission system is fully restored. We will announce this on this page.

Published articles

All articles published in JOSI remain available, and their DOI links work as before.

Contact

For any questions, please contact the editorial office at editor_josi@eng.unand.ac.id. Official communication about your manuscript will come only from the JOSI editorial team. If you receive an unusual request, for example a request for payment, please confirm it with us before responding.

We sincerely apologise for the inconvenience and thank you for your patience and understanding.

Sincerely,
Editorial Team
Jurnal Optimasi Sistem Industri (JOSI)
