The problem of slope stability is an important problem because it involves issues of human safety and other activities. To analyze slope stability, it can be seen through mechanical properties such as cohesion, friction angle and specific gravity. The friction angle is commonly identified as the variable strength of a slope but in previous studies it has been found a problem with the principle of variable friction angles as slope strength in a wedge failure. This test is based on wedge failure kinematics testing use stereonet and will be continued by analytic calculation of safety factors using point estimate method to be calculated as a whole to graph the relationship of friction angles and the value of safety factors. Based on analytic calculations, the difference in the strike value of planes A and B 102° untill 179° affects the safety factor, the greater of friction angle then make the greater value safety of factor. While the difference in the strike value of planes A and B 1° untill 101° graph the relationship between the friction angle and value safety of factor inversely proportional.
