In the subject of mine slope stability analysis, there are many analysis methods available, especially with the rapid enhancement of computational technology. The Finite Element Method is one of the most applied methods amongst practitioners dan academics in mining engineering. The method involves dividing 3 Dimensional models into small parts called elements. In this method, Shear Strength Reduction is adopted to determine the Factor of Safety, which in the terms of Finite Element Method also known as the Strength Reduction Factor. This research is intended to better understand one of the parameters in the Finite Element Method which is the tolerance value. The test is done by performing Finite Element Method analysis with a set of tolerance value variations. The result was then used to generate graphs to determine the effect of tolerance variations on Factor of Safety and Total displacement. The result indicates a trend in the increase of Factor of Safety and total displacement with the increase of tolerance value. From the Factor of Safety and displacement chart, it is found that the total displacement of 4.7 meters tends to stabilize when the tolerance value is 1 x 10-5 as it has an insignificant difference from total displacement generated with a tolerance value of 1 x 10-6 with the SRF of 1.2.
