The role of MRF in Indonesia's solid waste management system (case study of the Special Region of Yogyakarta, Indonesia)

Target of Indonesia's solid waste management is 30% reduction managed by 3R concept from sources, through community-based solid waste management (CBSWM) programs, such as solid waste treatment facility with 3R concept (TPS3R) or identical to the work principles of material recovery facility (MRF) on a smaller scale. Yogyakarta is one of the provinces in Indonesia which pioneered CBSWM activities. From 2008 to 2015, Yogyakarta had 37 MRF units with a service capacity of 800 households/MRF location. This study aims to identify performance and indications of various factors that determine the performance of MRF. The research was carried out in 19 MRF locations with data collection methods through observation and questionnaires, followed by processing data descriptively and grouping results based on activity flow. On average, MRF receives 4808 kg/month of solid waste, with a high percentage of residue (55%), the rest can be processed into compost (25%) and raw materials for recycling industries (20%). Therefore, there are four indications of output factors that affect MRF performance, i.e., incoming solid waste and product produced, processing residues, customer development, and MRF financial condition.
