Dear colleagues,

Currently, we are publishing Volume 8 issue 3; new articles will be added sequentially to the issue so they can be cited. DOI of the articles will be activated when the issue is complete. You can see its progress here: https://journal.ugm.ac.id/jtbb/issue/view/5246. 

Dear Colleagues,

As for improving the quality of our open-access journal model, we must implement a new Article Processing Cost (APC) policy. Accepted manuscripts submitted on January 1st, 2023 and forward, will be charged with the following APC: IDR 2.500.000 for Indonesian-affiliated authors, and USD 150 for manuscripts of foreign affiliation. However, we also offer APC reduction and waiver for those who qualify. Please check our author guidelines for more information.
We sincerely thank everyone for your support and trust in publishing your valuable work with us.

Best Regards,
JTBB Editorial Team.
