Mapping out the municipal solid waste generation and collection model using spatial multi-criteria evaluation

As of 2017, only 47% of Sukmajaya Sub-district’s waste was collected and transported. The City of Depok targeted to improve this rate to 73% by 2020. This research aims to evaluate the waste collection system in Sukmajaya Sub-district. Data were collected from government agencies, interviews, and field surveys. Data analysis was conducted using Spatial Multi-Criteria Evaluation (SMCE). Results showed that waste generation in Sukmajaya Sub-district was divided into three categories based on its quantity: three villages generated more than 150 m 3 waste/day, two villages generated 50-100 m 3 waste/day, and one village generated lower than 50 m 3 waste/day. Sukmajaya Sub-district had three types of residential waste collection models: indirect individual physical Waste Collection Point (WCP), indirect individual non-physical WCP, and direct individual door to door. Evaluation revealed four out of six existing physical WCP facilities were suitable in terms of spatial and physical conditions and posed low threat to pollute the surrounding environment.
