The National Criminal Code brought a paradigm shift in the criminal justice system in Indonesia, especially through two new types of basic punishments, namely supervision sentence and community service sentences. This form of punishment is an effort to reform criminal law that is oriented towards the rehabilitation and social reintegration of criminals, as an alternative to imprisonment which has so far dominated the criminal justice system. In its implementation, the function of community guidance is crucial to ensure the effectiveness of the punishment. The research method used in the discussion and analysis of the problem is normative juridical with a statutory approach and legal concepts. Community guidance plays a role in conducting community research, providing recommendations to prosecutors, and guiding convicts during the supervision or community service sentences period. However, strengthening regulations and institutions for the implementation of this function is still an urgent need because there are no implementing regulations that specifically regulate this matter. Therefore, this study emphasizes the importance of restructuring the role of community guidance in supporting the implementation of supervision and community service sentences so that the goals of correctional and criminal punishment can be achieved optimally.
