R Restitution as a form of recovery for victims of criminal acts is a right recognized in Indonesian law. This thesis examines the responsibility of the perpetrator in providing restitution to the victim in a criminal act that resulted in serious injuries committed jointly. The main problems discussed are first, whether each perpetrator in a criminal act that resulted in serious injuries committed jointly is responsible for providing restitution to the victim; and second, what is the basis for not granting the victim\\\'s request for restitution requested by the Witness and Victim Protection Agency (LPSK) in a criminal act that resulted in serious injuries committed jointly. This study uses a normative legal method that is descriptive analytical in nature. The data used are secondary data obtained through literature studies and interviews. The results of the study show that each defendant is responsible for his role in the joint violence as regulated in Article 170 of the Criminal Code, which is proven to have caused serious physical harm to the victim. The prison sentence of 2 years and 6 months reflects their responsibility, while the obligation to provide restitution in accordance with Law Number 31 of 2014 and Government Regulation Number 35 of 2020 aims to restore the victim\\\'s physical, psychological, economic losses, and medical costs. And one of the main reasons for the non-granting of the victim\\\'s restitution request through LPSK is the inaccuracy of the timeliness of the victim\\\'s submission of the restitution request, as well as limited information regarding the steps that must be taken. Based on these findings, it is recommended that the restitution process be improved by paying attention to transparency and easier access to information for victims, so that the victim\\\'s right to restitution can be optimally fulfilled.
