The increasing number of residents and the development of tourism activities in Pangandaran Regency makes the number of waste generation increases. But only 24.53% were served. The waste is transported to Purbahayu Landfill, which has an area of 9.5 ha. Purbahayu Landfill uses the open duping method which causes various environmental problems, such as odor, pollution due to leachate water, and methane gas emissions. At present the Purbahayu Landfill service life is up. To solve this problem, it is necessary to apply environmentally sound waste management, such as Mechanical Biological Treatment (MBT). MBT is a method for treating solid waste mechanically and biologically. The design of the MBT is based on primary data from sampling results and secondary data from related agencies or references. Waste generation in Pangandaran Regency at the end of the planning period was 116.38 ton/day and the highest composition was organic waste, which was 45.59%. The chosen alternative for mechanical processing is bag opening manually which requires a land of 130 m2 and biological processing namely windrow composting with a composting time of 5 weeks that requires land of 3800 m2. MBT process is able to reduce waste by 34.1% and produce biostabilised output of 52.72% with RA4 quality that has met the quality requirements for transferring to landfill namely 5.38 mg O2/gr BK, GB21 by 11.185 L/kg BK, and the size particles less than 60 mm.
