The application of chemical castration punishment for sexual predators is an appropriate policy to protect children from sexual predators in Indonesia, as formulated in Article 81 and Article 81A of Government Regulation in Lieu of Law Number 1 Year 2016 on the Second Amendment to Law Number 23 Year 2002 on Child Protection. It is hoped that this policy can reduce the number of sexual violence that occurs in children. But there are polemics about the punishment, including; various groups think that castration punishment has violated human rights, the absence of technical instructions to perform chemical castration, to the rejection of the Indonesian Doctors Association (IDI) to become the executor of chemical castration because it is contrary to the medical code of ethics.
