Abstract
The garbage problem is getting worse every year. Population growth is the main cause of the expansion of urban waste dumps and landfills. Based on these conditions, a study was carried out using a combination of LandGEM, IPCC, and LCA modelling to examine the potential for methane gas production in landfill activities at Bengkala Landfill due to a lack of assessment or validation data to measure the presence of methane gas in TPA. Data validation was carried out by comparing the LandGEM and IPCC models. Life Cycle Assessment (LCA) is also used to evaluate the environmental impact of waste handling at the Bengkala TPA. The conclusions drawn from the sampling findings at the Bengkala TPA and the analysis results are as follows: The average daily waste generated is 1.95 litres or 0.36 kg per person. The average density of waste is 185.23 kg/m3, and in the Bengkala TPA, the composition of garden waste reaches 36%, while textile waste is only 2.35%. With methane gas emissions of 3.80 Gg/year for CAA-Conventional default, 1.93 Gg/year for Inventory default, and validation of IPCC model results of 0,99 Gg/year, the calculation of the estimated production of methane gas produced from the process landfilling at the Bengkala landfill has the highest yield in 2034. Methane gas in the TPA can be utilized to produce electricity and biogas. Convert methane gas to electricity with a total potential of 856.688 kWh Kilowatt of electric power. The scenario of waste management using the sanitary landfill method (scenario 0) has the smallest environmental impact. However, if a more sustainable approach that considers recycling and composting are desired, scenario 2 may be a better choice than scenarios involving thermal treatment (scenarios 1 and 3).
