Starting 2017 issue, to enhance the quality of this journal, we need to increase the publication fee to US$ 300 for foreign authors and IDR 3,000,000,- for Indonesian authors. The cost of each printed page that contains colored figure still remains (US$50 or IDR 500,000).

We also expanded the waiver policy, and not limit to group A and group B countries. All authors may ask a waive, and they need to send letter of waiver to editor-in-chief explaining the importance of the study and why author(s) need to be waived. The decision is made prior to the process of the review and it is the editors' priviledge to approve or reject the request.
