Manuscript withdrawal is strongly discouraged, it is a waste of valuable resources that the publisher put. If the author still requests withdrawal of their manuscript, the following guidelines have to be followed
Manuscript withdrawal will be permitted only for the most compelling and unavoidable reasons. It is unacceptable to withdraw a manuscript from a journal because it is being accepted by another journal;
The author should submit a request to the editorial office as a letter signed by all authors stating the full cause that led to the step of manuscript withdrawal;
In a case where a manuscript has taken more than six months time for the review process, publishers allow the author to withdraw the manuscript without paying any charges;
If the manuscript is still in the peer-reviewed process, the author has to pay 500.000 (IDR) per manuscript as a penalty of withdrawal;
If the manuscript is already accepted for publication, the author has to pay 1.000.000 (IDR) per manuscript as a penalty of withdrawal;
If the author doesn't agree to pay the penalty, the author and his/her affiliation will be blacklisted for publication in this journal;
Authors must not assume that their manuscript has been withdrawn until they have received an appropriate notification to this effect from the editorial office.
