This study examines the role of correctional intelligence in utilizing inmate information for the early detection of security and order disturbances at the Class IIA Kalianda Correctional Institution (Lapas). A descriptive qualitative approach was used, with data collected through semi-structured interviews, observation, and documentation involving eight informants: the Head of the Security Unit (KPLP), the Head of the Security and Order Section (Kamtib), three correctional officers, and three inmates. Data were analyzed using the Miles, Huberman, and SaldaƱa interactive model, and verified through source, technique, and time triangulation. Role Theory (Linton) and the Intelligence Cycle (Lowenthal) were used as analytical frameworks. Findings show that correctional intelligence connects inmate information about conditions inside the housing blocks with security decision-making. This role rests on officers' status in the security function, their rights and obligations, their interaction behavior, and organizational expectations, and runs through collection, processing, analysis, and dissemination. Inmate information serves as an early lead rather than conclusive evidence and must be verified. Obstacles include sources' fear of being identified, rumors and personal interests, limited time and personnel, loss of context during reporting and shift changes, coordination gaps, and limited feedback to sources. Optimization efforts include humane communication, source protection throughout the process, structured recording, clearer risk analysis, timely reporting, and limited feedback. The study recommends clearer division of responsibilities, concise reporting guidelines, and separate, restricted storage of source identities.
