C Children who are facing the law need special protection in the criminal justice process. law number 11 of 2012 concerning the juvenile criminal justice system requires detained children to be placed in a temporary child placement institution (lpas). however, in the sukabumi district court decision number 1/pid.sus-anak/2022/pn skb, a 17-year-old child involved in a narcotics crime was instead placed in the state detention center. this study uses a normative legal research method that is descriptive and analytical with a legal principles approach. primary data was obtained through interviews with the sukabumi city police, sukabumi class iib prison, and lecturers of the faculty of law, trisakti university, while secondary data were obtained from laws and regulations, court decisions, books, and legal journals. the results of the study showed that the detention was not in accordance with article 30 paragraph (2) and paragraph (3), article 33 paragraph (4) and paragraph (5), as well as article 84 paragraph (1) and paragraph (2) of the sppa law because the child was not placed in lpas or lpks, so it was contrary to the principle of the best interest for the child and the principle of protection. the legal remedy that can be taken is pre-trial. there are two views, namely the conservative view that considers the inappropriateness of the place of detention only as an administrative offense outside the object of pretrial, and the progressive view that views the provision of placement of children in lpas as a legal condition for detention so that the incompatibility can be tested through pretrial.
