Waste accumulation in a landfill is often made a problem, especially when the landfill has reached the end of its service life, so there is a need for further utilization of the landfill, one of the things that can be done is to utilize the landfill as a place where a building can be built. In this research, a review of the waste settlement and slope stability uses the Plaxis Program to determine whether the landfill is able to withstand the burden of buildings. The research is located at Piyungan Yogyakarta Landfill. Material data in the form of the value of the friction angle, the volume weight of waste, and the modulus of elasticity obtained from previous research. From the results obtained, it is known that the deformation of waste that occurs shows a significant settlement up to 45 cm with load 1250 kg/m2 so the foundation design at landfill area needs concern about high settlement, and this can be used as the basis for sustainable utilization of landfill.
