摘要：In Indonesia, trough Sanimas (Community Based Sanitation Program), which is coordinated by the Ministry of Public Works and Public Housing in collaboration with local governments and communities, establishes KSM (Community Self-Help Group) for Communal Liquid Waste Management Installations. The purpose of this study is to examine the factors that cause the sustainability of community-based liquid waste management. This research uses mixed methods, that is by analyzing quantitative data from the SKM (Community Satisfaction Survey) 2019 on the Implementation of Infrastructure Services in Yogyakarta City and then validated with primary data collected from semi-structured interviews with the head of KSM from the three well-managed Communal IPALs. Instead of the active participation of the community, the result shows in the case of Yogyakarta City, the key of Communal IPAL management sustainability is still more on the role and commitment of KSM or community leaders rather than the active participation of the community.
