Management of HIV/AIDS Prevention Services in the MSM Group at KTH Mandalika RSUD Praya still needs to improve the effectiveness of HIV/AIDS prevention, more intensive strategic planning is needed to overcome the increase in HIV prevalence, involving an approach through a TEAM of Field Officers in providing more effective education and social support through VCT services and hotline counseling. Coordination and a stable organizational structure in KTH Mandalika RSUD Praya cannot be ignored, so that response efforts can run more focused. Staff training and development, especially those related to handling PLWHA, needs to be based on objective selection and unit needs, while the use of information technology, such as the SIHA 2.1 application and RS SIM, can be improved to ensure accurate recording and reporting. Management of BHP and ARV availability needs to be optimized through efficient coordination with the District and Provincial Health Services, and regular evaluations need to be carried out to increase distribution efficiency. Implementing the recommendations from 4 informants can have a significant positive impact in managing the management of HIV/AIDS prevention services at KTH Mandalika RSUD Praya, so as to reduce HIV transmission, and provide better support to PLWHA in the MSM community..
