With the planned transfer of the final waste processing location in the City of Bandung from TPA Sarimukti to TPPAS Legok Nangka requires the City of Bandung to reduce waste generation before it is transported to the TPA, with the relocation of the TPA, it will significantly affect the burden of transporting waste to the TPA, in addition to the City of Bandung. only given a quota of 1200 tons per day to be transported to the Legok Nangka TPPAS. With the Bandung City Waste Management Master Plan 2021 – 2031, the City of Bandung plans 2 scenarios to reduce waste transported to the landfill, starting from processing organic waste, limiting other waste generation which changes the waste management system in the City of Bandung which previously was collect-transport- discard to be more focused on the 3R. With this change in the waste management system, it is hoped that the waste transported to the TPA can be reduced, besides that, the financing of waste management can be minimized and of course reduced GHG emissions which have been known to be dominated by transportation activities. The waste management that will be the main focus in this research is road sweeping waste consisting of leaves, sand, stones and Solid waste thrown away by road users carelessly. The dynamics of street sweeping waste management based on the Bandung City Waste Management Master Plan and its effect on changes in emission levels and financing are calculated in 4 scenarios, including the BAU scenario with no change in road sweeping waste management, namely the collect-transport-dispose principle, scenario 1 which is calculated based on scenario 1 in the street sweeping waste management master plan, scenario 2 which is calculated based on scenario 2 in the street sweeping waste management master plan and scenario 3 which is a combined optimization between scenario 1 and scenario 2. Emissions calculations using the database from IPCC 2006 and cost calculations using the NPV and BCR. Based on the available data, the increase in the length of road sweeping has increased by 1% annually from 14% in 2021 to 18% in 2025, the amount of road sweeping waste generation in Bandung City is 0.15 kg/m. So that the generation of road sweeping waste is 13.76 tons in 2021 and reaches 17.13 tons in 2025. From the calculation results, the scenario with the lowest emission value is scenario 3 of 2.11 Gg CO2-eq and the largest emission is obtained from scenario 3 2 with an emission value of 14.79 Gg CO2-eq. For financing based on economic feasibility using the NPV and BCR methods, all of the 4 existing scenarios do not meet the standards, so the scenario that is considered the most feasible is the one with the BCR value closest to 1 and the least negative NPV value. The best scenario in terms of financing is scenario 3 with a BCR of 0.15 and a negative NPV of Rp. 11,336,591,673.09.
