<![CDATA[The solid waste management system requires a community component that is directed through Community-Based Solid Waste Management (CBSWM) activities. One of the CBSWM activities in Indonesia is TPS3R (3R Waste Treatment Facility) or MRF (Material Recovery Facility). The fact on the ground was that many TPS3R management systems were not running optimally. This has the potential to hinder the sustainability of the TPS3R program. This sustainability can be assessed through proper instruments that measure program effectiveness. This research aims to develop an instrument for assessing the level of sustainability and experiment with it at TPS3R. The instrument is used to analyze the sustainability of the studied programs to determine which ones are feasible to continue. The instrument consists of 20 indicators, parameters, assessment scales, and weightings that are integrated into five aspects of waste management, including operational, technical, regulatory, community participation, financing, and institutional aspects. The research analysis method applied is the scoring method to assess the level of sustainability in TPS3R. The research was conducted at six TPS3R locations in Sleman Regency Yogyakarta. Experiments with the instrument revealed that each TPS3R received a distinct score and was classified according to the planned level of sustainability. The results of the sustainability level assessment are divided into three statuses: very sustainable, achieved by TPS3R Purwo Berhati with a percentage of 80%. Then, the sustainable status was achieved by TPS3R Brama Muda, TPS3R Mexicana, and TPS3R GIAAAAAT with percentages of 70%, 70%, and 78%, respectively. Finally, the status of fairly sustainable was achieved by TPS3R Ben Resik and TPS3R Randu Alas, at 58% and 57%, respectively. Based on the study's results, this instrument can be utilized in the sustainability assessment of TPS3R.]]>
