The author is not allowed to withdraw submitted manuscripts, because the withdrawal is a waste of valuable resources that editors and referees spent a great deal of time processing submitted manuscript, money, and works invested by the publisher.
If author still requests withdrawal of his/her manuscript when the manuscript is still in the peer-reviewing process, the author will be punished with paying 150000.00 (IDR) per manuscript, as withdrawal penalty to the publisher. However, it is unethical to withdraw a submitted manuscript from one journal if accepted by another journal. The withdrawal of manuscript after the manuscript is accepted for publication, the author will be punished by paying 300000.00 (IDR) per manuscript. Withdrawal of manuscript is only allowed after the withdrawal penalty has been fully paid to the Publisher.
