Management of waste in Indonesia still poses various challenges, such as inadequate waste sorting, the need for proper transportation for disposal, and accumulation in Temporary Storage Sites/Landfills (TPS/TPA) causing adverse effects on the environment, health, and scenery. To alleviate the burden on TPS/TPA due to waste accumulation, incineration can be a solution to treat non-decomposable waste. The Masaro ITB Incinerator Technology, implemented in Babakan Village, Ciwaringin District, Cirebon Regency, has been in operation for more than 4 years to manage local waste, supported by funding from Dow Chemical International, the Directorate General of Higher Education (Ditjen Dikti), and PT Masaro Jabar Lestari. This research aims to improve the Masaro incinerator by maintaining operating temperatures within the range of 800–1000 oC to achieve complete combustion and eliminate toxic gas content in the exhaust. Experiments will be conducted by developing a continuous waste feeding scheme with variations of wet and dry waste, and adjusting the initial furnace loading capacity. The study will be reinforced with automated temperature measurements at 9 points on the furnace walls, characterization of exhaust gas emissions, and characterization of the washing water from the combustion exhaust. Efforts to maintain the operational temperature of the Masaro Incinerator are carried out by designing and creating belt conveyors and screw conveyors to enable the waste feeding process to run automatically and continuously, along with the addition of a pretreatment system. Research findings indicate that the amount of waste load inside the furnace is directly proportional to the operating temperature of the combustion furnace, applicable to both wet and dry waste variations. All parameters of combustion gas emissions are below the threshold limit, while for parameters of washing water from the combustion exhaust, all are below the threshold limit, except for BOD and COD.
