Starting from the manuscript publishing on October 2023, the Author(s) should pay an Article Processing Charge (APC) of Rp. 400.000,- per article, once the manuscript was accepted. An invoice will be sent to the Authors whose article was accepted. Please be noted that the payment of APC can be proceeded by bank transfer which will be informed to the Corresponding Author together with the invoice. The accepted articles will not be published until the APC was paid by Author(s). The APC will be used to maintain the DOI registration and the full-text PDF articles production cost.
