Law enforcement in the field of drugs and food is an important part of efforts to protect public health. Civil Servant Investigators (PPNS) of the Food and Drug Supervisory Agency have special authority to conduct investigations into criminal acts in the field of food and drugs based on sectoral regulatory provisions. However, in its implementation, these authorities still face various normative and practical obstacles, especially related to coordination with other law enforcement agencies and the limitations of supporting facilities. This research aims to analyze the authority of the Ambon Food and Drug Supervisory Agency's Civil Servant Investigators in law enforcement related to drug and food crimes and to identify the factors hindering the implementation of that authority. The research method used is normative legal research with a statutory approach and a conceptual approach. The research results show that the authority of the Civil Servant Investigators of the Ambon Food and Drug Supervisory Agency has been clearly regulated in the Criminal Procedure Code and sectoral laws, particularly the Health Law and the Food Law. However, its implementation still faces obstacles such as limited human resources, infrastructure, coordination among law enforcement officers, and low public legal awareness. Therefore, it is necessary to strengthen regulations, enhance institutional capacity, and optimize coordination among law enforcement officers to improve the effectiveness of law enforcement in the field of drugs and food.
