Avalanche is a disaster that is dangerous and can harm humans. Application of plaster as a retaining wall is one way to prevent the occurrence of landslides. Development of slope stability analysis in geotechnical engineering will always be followed by developments in the field of soil mechanics and rock mechanics as a whole. Slope stability problems usually occur when there is interference with the balance of the slope, which may be caused by human activity or natural. When a moving or unstable slopes where the movement would clearly endanger the surrounding environment, then the in-depth analysis of slope stability is required. That analysis including understand the mechanism of collapse and factor its cause as well as the evaluation stability of slope of the most precise for overcome in order slopes do not landslides. Slopes not landslides akan be obtained if we number the security (safety factor) the results of analysis of ??? 1.5.\ud A common problem encountered on slope stability of natural slopes or slopes either pile / soil base. Shear strength of a soil is not capable of assuming the conditions of excessive workload. In other words, the collapse of a slope is often caused by increased shear stress and the work of a land mass or a decrease in shear strength of the mass of soil (soil shear strenght).\ud To obtain an optimal solution to overcome the problem of stability in order not to soil erosion, water pressure is required calculations, land and other expenses properly and properly so as not to cause damage and even loss of life in the future
