Abstract

Various problems in solid waste management are covered, among others concerning nonorganic solid waste deposited in Final Disposal. The generation volume amounting to 330,01 tons/day. The solid waste disposal consists of 66% organic and 34% nonorganic. To develop Final Disposal Manggar, Balikpapan, East Kalimantan, one special zone is planned to accommodate nonorganic solid waste. The landfill method for sanitary landfill is covering total area of 25 ha of Final Disposal. The feasibility calculation of the Final Disposal based on Le Grand Method. The original design for three landfill zones in Final Disposal Manggar was specified only for nonorganic waste, however, the plan will be made in 2 alternatives i.e. alternative 1 with separate system and alternative 2 with combined organic and nonorganic waste processing. Based on the calculation of the area totalling 17261,2 m2, the productivity period of zone 3 (three) in alternative 1 is 2 years and 5 months. As for alternative 2 the generate combined waste, except waste from market place with a density of 290 kg/m3 for 2014, which make the solid waste generation 438 m3/day, the productivity period of the combined system is 385 days.
