The amount of municipal waste has been steadily increasing over the past decade because of increasing population and solid waste generation. Until now, waste management in DKI Jakarta has been carried out using the collection and disposal method with the final processing of waste to the Integrated Waste Management Site in Bantargebang, Bekasi City. Based on data from the DKI Jakarta Environmental Services in 2019 it was noted that the average amount of waste dumped into the TPST Bantargebang is 7,000 tons per day and will continue to increase along with population growth. DKI Jakarta plans to build four Intermediate Treatment Facilities (ITF) namely Sunter ITF, Rawa Buaya ITF, Jagakarsa ITF, and Cakung- Cilincing ITF as waste management in DKI Jakarta to reduce the amount of waste entering the Bantargebang TPST. This study aims to find the optimum route in urban waste transportation using the Geographic Information System tool with Network Analysis to minimize the distance and time resulting from the waste transportation from all TPS using Arm Roll trucks as transport to the 4 ITF locations. In this study the optimum route for dump trucks entering ITF Sunter will also be calculated. The Closest Facility feature is used to find the optimum route for arm roll trucks while the Vehicle Routing Problem feature is used for the optimum route of a dump truck. So that the waste carried does not exceed the capacity of the truck, the Capacitated Vehicle Routing Problem (CVRP) method is used. There are 150 TPS points that use arm roll trucks and 301 TPS points that use dump trucks as waste transportation. From the calculation results, the optimum route for arm roll trucks requires time and distance of 66.32 hours and 2,173.63 km. For optimum dump truck routes, the time and distance obtained are 69.75 hours and 2,092.6 km. The results of this study can assist stakeholders in making decisions to reduce costs.
