Currently, the Indonesian National Armed Forces (TNI) is involved in securing civilian institutions, namely the Prosecutor's Office, where the security of the prosecutor's office is the authority of the Indonesian National Police (Polri). This security task refers to changes in regulations in Law Number 3 of 2025 concerning amendments to Law Number 34 of 2004 concerning the Indonesian National Armed Forces. This raises questions regarding the limits of the TNI's authority in securing the prosecutor's office, especially after the revision of the TNI Law and the implications of TNI involvement in securing the prosecutor's office on the principle of dividing defense and security functions. The type of research used is normative legal research with a statutory approach using qualitative typology. The results of the study indicate that the TNI's authority in securing the Prosecutor's Office stems from the framework of Military Operations Other Than War (OMSP) based on Law Number 3 of 2025. However, the regulations are still general and do not specify the scope and mechanism limits explicitly, potentially blurring the separation of defense and security functions as mandated by Article 30 of the 1945 Constitution, and creating overlapping authority with the Indonesian National Police. This involvement also has implications for the shift of the TNI's function to the realm of domestic security, weakening civilian supremacy, and potentially reducing the quality of democracy.
