The method of investigation is carried out by means of field investigations, testing of soil mechanics laboratory, literature study to obtain information / data on soil movements and observations of soil movements in the area of investigation. The slope stability analysis was calculated using the Slope/w program from Geostudio 2007 software. The results of slope stability analysis at 3 locations with different slope, showed that location 1 slope 35º and location 2 slope 65º under wet or saturated soil conditions obtained Safety Factor (Fs) location 1 with a value of 0.626 and location 2 value, 0.367 less than 1.25 means that the slope is normal / frequent ground motion or unstable slopes, but different at location 3 with a slope of 25º obtained a Safety Factor (Fs) of 1.430 which means that more than 1.25 the ground movement is rarely stable or the slope is stable. Whereas in dry / unsaturated soil conditions, locations 1 and 2 obtained a Safety Factor value (Fs) of 0.680 location 1 and location 2 obtained with a value of 0.404 which means less than 1.07 slopes remained unstable, but location 3 on dry soil conditions Safety Factor (Fs) 1,450 over 1.25 means that the slope is stable.
