The high volume of waste that is not followed by properly waste management method, makes the waste management in Lhokseumawe not optimal. This problem is shown by the level of waste service is only about 38 %, while the waste that is not transported will be cumulative in any places. This is showed that the level of waste service is below of the minimum service standard that is 60 %–90 %. It is necessary to improve the waste management, especially in the utilization of waste to reduce the waste and landfill load. This research aims to evaluated and analysis of waste management in Lhokseumawe by two waste reduction scenarios, that are waste bank scenario and recycle scenario. The method that were used in this research are material balance analysis, lifetime of landfill, and cost analysis. The result showed that waste reduction by scenario 1 and scenario 2 can reduce of waste in landfill about 49.8 % and 51.02 %. The lifetime of landfill by the waste reduction can be used for 28 years from the lifetime 18 years. Investment cost estimated that required in scenario 1 and scenario 2 are smaller than the investment cost of existing, respectively IDR746,646,860, IDR755,530,822 and IDR1,202,644,444.
