<![CDATA[ABSTRACT HIV prevention among Men who have Sex with Men requires collaboration between primary health facilities and community-based organizations to overcome service access barriers and deeply rooted social stigma in society. Objective to evaluate the implementation, process, outcomes, and challenges of collaboration between Community Health Centers and Non-Governmental Organizations in HIV prevention among Men who have Sex with Men risk groups in Mataram City. Descriptive evaluative qualitative research using in-depth interviews, participatory observation, and documentation studies involving seventeen informants including Community Health Center heads, HIV program managers, Non-Governmental Organization staff, People Living with HIV/AIDS, and Health Office officials conducted during October to November 2025 at four Care Support and Treatment Community Health Centers. Collaboration functioned effectively and adaptively with complementary role division that improved service access, antiretroviral treatment adherence, and continuity of care for key populations. Coordination mechanisms combined informal and formal communication with a single-door reporting system through Community Health Centers. Main constraints included limited human resources, absence of standardized collaboration operational procedures, dependence on personal relationships, and persistent strong social stigma toward HIV. Collaboration proved effective in enhancing HIV program achievements but requires strengthening of institutional aspects, formal governance, and policy support to ensure long-term sustainability. Keywords: Community Health Center Collaboration, Non-Governmental Organizations, HIV Prevention.
