<![CDATA[This study is motivated by the low self-control of narcotics user inmates, which appears in impulsive tendencies, difficulty in obeying rules, and vulnerability to relapse. The Class IIB Muara Sabak Narcotics Correctional Institution runs the Rumah Tahfiz Program as a personality development program based on memorizing the Qur'an. This study aims to describe the implementation of the Rumah Tahfiz Program in forming inmates' self-control and to identify its supporting and inhibiting factors. The study uses a descriptive qualitative approach with semi-structured interviews with six informants, observation, and documentation, analyzed using George C. Edwards III's policy implementation theory and James R. Averill's self-control theory. The results show that the program has been implemented through communication starting from the orientation period, resources in the form of instructors, partner teachers, peer tutors, basic facilities, and budget allocation, committed implementers supported by incentives in the inmate development assessment system, and a bureaucratic structure with standard operating procedures and a clear division of tasks. The program contributes to the formation of behavioral control, cognitive control, and decisional control, although the changes vary among inmates. Supporting factors include leadership support, patient instructors, and peer support, while inhibiting factors include limited teachers and learning space, differences in initial Qur'an reading ability, and participant boredom. This study recommends adding teachers, providing a dedicated learning room, grouping participants by ability, and developing an instrument to monitor self-control.]]>
