All Manuscripts Must Be Submitted in English

Dear Authors,

As part of J-Cosine's commitment to enhancing its international visibility and academic quality, all manuscripts submitted for publication must be written entirely in English.

Beginning with Volume 9, Issue 1, J-Cosine is transitioning into an international journal and will fully comply with international scholarly publishing standards. This policy is also aligned with international publication guidelines and the academic quality improvement initiatives promoted by the Ministry of Education, Culture, Research, and Technology of the Republic of Indonesia.

Manuscripts submitted in languages other than English will not be processed for review. Authors are therefore encouraged to ensure that their papers are written in clear, accurate, and academically appropriate English prior to submission.

We appreciate your understanding and cooperation in supporting J-Cosine's continuous development toward higher international standards.
