A crime can be defined as an action prohibited by legal regulations followed by the threat of criminal punishment for anyone who violates the prohibition. The influence of technological developments has caused children not only to become victims of sexual violence, but have become perpetrators of sexual violence. Children who become perpetrators of criminal acts must have their rights protected in accordance with the Convention on the Rights of the Child, Law No. 35 of 2014 concerning Child Protection and Law No. 11 of 2012 concerning the Child Criminal Justice System. The formulation of the problems in this study are as follows; 1. How do the statutory provisions in Indonesia regulate the legal protection of children who are perpetrators of sexual violence? 2. How is the implementation of legal protection against child perpetrators of sexual violence in the judicial process in Indonesia? The initial approach of this research was conducted from a juridical perspective, in which the law is considered as a norm that is the center of attention. The legal issues considered in this research are analyzed using various legal sources, including written and unwritten legal sources, as well as binding primary legal sources, namely Law No. 11 of 2012 concerning the Child Criminal Justice System, Law No. 35 of 2014 concerning Child Protection and secondary legal materials obtained from various sources such as books, journals, opinions of experts, and so on. The conclusion of this research is that the implementation of legal protection of the rights of children who are perpetrators of sexual violence has gone well, but this has caused injustice to victims.
