摘要：Organic solid waste will undergo a decomposition process and produces some gases compounds such as a large enough of Methane (CH4), Carbon Dioxide (CO2) with Oxygen (O2) and N2. The high heating value of CH4 in biogas can make biogas as a good source of renewable energy and environmentally friendly. Biogas calorie efficiency is proportional to the concentration of CH4 in biogas. However, the quantity and quality of biogas that produced in landfill depend on the characteristic and density of domestic solid waste in landfill. The composition of organic and inorganic waste and the density of waste pile will alter the CH4 content. This study focuses on measuring CH4 content of the solid waste with different density while also identifying the composition of disposed solid waste. The result indicates that the CH4 content ranges from 33% to 57.7% with 22.19% to 42.24% of CO2 and approximately 1.21% - 7.92% of O2. The presence of inorganic waste and density level of waste contribute to the decomposition rate and CH4 content.
