The Free Nutritious Meal (MBG) Program is one of the government's strategic policies aimed at enhancing the quality of human resources by fulfilling the nutritional needs of students and vulnerable groups. However, the success of the program's implementation is determined not only by budget availability and government policy, but is also heavily influenced by the effectiveness of oversight, legal culture, and community participation. The problem addressed in this research stems from the ongoing challenges in the implementation of the MBG program, particularly regarding monitoring mechanisms, public legal awareness, transparency, and public involvement in ensuring the program runs effectively and targets the right recipients. This study aims to analyze the implementation of oversight for the Free Nutritious Meal Program, the effectiveness of legal culture in supporting program monitoring, and the role of community participation in conducting such oversight. The research method employed is normative legal research utilizing statutory and conceptual approaches, which examines various legal provisions, legal culture theories, and literature related to public policy oversight. The findings are expected to indicate that the effectiveness of the Free Nutritious Meal Program depends not only on the existence of regulations, but also on the quality of the public's legal culture and the active involvement of various stakeholders in monitoring. Strengthening regulations, increasing legal awareness, and optimizing community participation serve as crucial factors in achieving a transparent, accountable, and sustainable program implementation.
