<![CDATA[The population growth in Sleman Regency has led to an increase in waste generation, necessitating an effective and participatory management system. This study aims to map the distribution of Community-Based Waste Management (CBWM) infrastructure, such as TPS3R, waste banks, and "waste donation" programs, and to evaluate their distribution and effectiveness using Geographic Information Systems (GIS). A descriptive quantitative method with a spatial approach was employed using QGIS software. Data analysis utilized overlay, buffering, and nearest neighbor analysis to evaluate the spatial service coverage. The results indicate a significant surge in the number of facilities, rising from 234 units in 2022 to 508 units in 2025; however, the distribution remains uneven. Population density significantly influences this distribution, where Ngaglik District, with the highest density (202 people/ha), still possesses a sub-optimal facility ratio compared to other regions. This study recommends spatial evidence-based priority zoning, including the establishment of a 500-meter service buffer in densely populated settlements and the revitalization of inactive units. These mapping results are expected to serve as a framework for more measurable and sustainable policy-making and evaluation of waste management in Sleman Regency]]>
