This thesis examines the experiences of Indonesian prison officers implementing prison-based deradicalisation programs. It investigates challenges faced by Indonesian prison officers implementing such programs and analyses their views related to the establishment of a specialised prison for terrorists in the Indonesian correctional system. An evaluation of the needs of Indonesian prison officers in implementing prison-based deradicalisation programs found that appropriate trainings and good partnerships are essential. Moreover, the thesis identifies important policy recommendations and regulation reform for improving Indonesian prison officers’ roles in terrorist rehabilitation.
