Supervisor I: Prof. Ir.Ari Handono Ramelan, MSc. (Hons), Ph.D. Supervisor II: Prof. Dr. Dwi Aries Himawanto, S.T., M.T ABSTRACT Increase in volume of waste generated by municipal residents, change in the quality of waste composition and the treatment and disposal method of waste collected are of major concern in Surakarta City which needs urgent workable solutions, hence, this research study has been necessitated. The objectives of this study is to (1) determine the existing condition of waste stream composition in Surakarta City, and (2) evaluate, based on the result of waste stream composition study, under what circumstances waste to energy technologies will be feasible in Surakarta City using life cycle assessment. In carrying out this research simple random sampling was used. At the final landfill site, measurement on weight, separation of waste into different categories were made and recorded. Proximate analysis was undertaken at the laboratory to determine the moisture content, volatile matter content, ash content, fixed carbon content and calorific value of selected samples of MSW. Finally, life cycle assessment method was used as an analytical tool to assess the feasibility of suitable waste to energy technologies based on the results of waste quantity and composition study undertaken in Surakarta City. The results showed that out of the samples of MSW collected, 11 types of wastes were identified including food waste, plastic, wood waste, paper, leaf, vegetable, metal, yard waste, textile, rubber and others. Out of these wastes, leave waste was found to be highest with 21.96%, followed by food waste 18.35%, vegetable waste, 16.08% paper with 11.07%, and plastic with 10.92%, wood waste with (5.8%), yard waste (4.63%), textile (4.13%), rubber (2.93%) and other smaller fractions which make up of 4%. In general, MSW in Surakarta City is largely made up of 67% of organic components of waste while inorganic components of wastes make up another 33%. The results of proximate analysis indicated that organic wastes had high moisture content of 81.67% compared to inorganic wastes with 25.8%. On average, the samples of MSW contributed high volatile solids of 35%, ash content of 6.3% and fixed carbon content of 5.5% respectively. The overall result of calorific value was high and found to be 15,770 MJ/kg as dry basis. In this case, inorganic fractions of wastes have high calorific value in general as compared to organic wastes. Based upon the condition of waste composition identified, when performing life cycle assessment, the result showed that out of all the waste to energy technologies discussed, incineration technology was found to be the most viable form of waste to energy technology option. Incinerating MSW decrease the space they take up and reduce the stress on landfills experienced at Putri Cempo landfill site. Key word: waste composition, waste to energy, life cycle assessment
