<![CDATA[Violence among inmates is a form of security and order disturbance that threatens the safety and sense of security of those held in correctional institutions. This research is motivated by the condition of the Class IIB Purbalingga State Detention Center (Rutan), where the number of occupants exceeds its capacity, making it prone to friction between inmates. The aim of this study is to examine the security strategy based on Situational Crime Prevention in preventing violence among inmates and to identify the obstacles in its implementation at the detention center. This research employs a qualitative approach with a descriptive method, using in-depth interviews, observation, and documentation involving security officers, detainee services staff, and an inmate selected through purposive sampling. The data were analyzed using Ronald V. Clarke’s Situational Crime Prevention theory. The findings show that the security strategy has been carried out across all five dimensions of the theory, namely increasing the effort, increasing the risk, reducing the rewards, reducing provocations, and removing excuses, through entrance inspections, routine patrols, CCTV surveillance, room placement, mediation, and repeated communication of rules. However, its implementation still faces obstacles, such as a limited number of officers, inadequate security equipment, overcrowding, a seniority culture among inmates, low willingness to join rehabilitation programs, and reluctance to report threats. The study concludes that the strategy is consistent with the theory and mainly preventive, but CCTV coverage, staffing, overcrowding, and formal post-incident evaluation still need to be strengthened.]]>
