Purpose:This study aims to analyze legal regulations, the effectiveness of implementation, as well as obstacles and solutions to joint raids by law enforcement officers as a security strategy to prevent drug abuse by inmates in state detention centers. Research Methodology:The study used normative legal methods combined with an empirical juridical (socio-legal) approach, located at the Class IIA Batam Detention Center. Primary data were obtained through in-depth interviews and observations of detention center officers, the National Police (Polri), the National Narcotics Agency (BNN), and the Indonesian National Armed Forces (TNI) using purposive sampling. Secondary data were collected from laws and regulations and national and international journal articles. These data were then analyzed using comparative descriptive qualitative methods through reduction, classification, legal interpretation, and deductive drawing of conclusions. Results:The research results show that the legal regulation of joint raids has a strong legal basis through Law Number 22 of 2022 concerning Corrections, Law Number 35 of 2009 concerning Narcotics, and Regulation of the Minister of Law and Human Rights Number 8 of 2024, which is strengthened by a memorandum of understanding between agencies. Its implementation at the Class IIA Batam Detention Center through weekly raids with the National Police, the National Narcotics Agency (BNN), and the Indonesian National Armed Forces (TNI), the daily One Day One Room program, and periodic urine tests has proven effective in preventing the entry of narcotics, but still faces obstacles such as limited human resources and detection technology, the lack of integrated standard operating procedures between agencies, and the potential involvement of unscrupulous officers. Conclusions:Strengthening the joint raid strategy requires the development of integrated standard operating procedures across agencies, increased human resource capacity and detection technology, and enhanced officer integrity, while upholding the principles of justice and legal certainty for inmates. Limitations:The research is limited to one locus, namely Batam Class IIA Detention Center, so generalizing the findings to other detention centers or correctional institutions with different characteristics requires caution. Contributions:This research contributes to the development of correctional law and criminal law studies regarding security strategies based on inter-agency collaboration, and can be a policy reference for the Ministry of Law and Human Rights, the Indonesian National Police, the National Narcotics Agency (BNN), and the Indonesian National Armed Forces (TNI).
