We would like to inform you that due to technical issues resulting from a recent hacker attack, we have established a new, more secure system to ensure the safety and continuity of future publications. Consequently, all issues starting from Volume 1, Issue 1 and onwards will be published exclusively on the new platform at https://jobc.journal.unej.ac.id

We sincerely apologize for any inconvenience this transition may cause and greatly appreciate your understanding and cooperation as we continue to improve the quality and security of our journal.
