Abstract
Waste accumulation in a landfill is often make 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 study, a review of the waste deformation and slope stability uses the Plaxis Program to determine whether the landfill is able to withstand the burden of existing 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. From the results obtained, it is known that the deformation of waste that occurs shows a significant settlement in foundation so that not all buildings can be recommended to be built on the landfill site, and the value of safety factor generated from PLAXIS shows that the slope is still safe to withstand the load.
