M Mining companies engaged in mining activities will inevitably be faced with geotechnical challenges. To overcome this problem, various slope stability and instability analysis methods began to be developed with the aim of providing a way to determine unambiguously whether the slope of a particular slope tends to slide or will remain stable. Another aim of this slope stability analysis is to produce a slope angle that ensures that workers in the pit are protected from potential work accidents that might occur. In this research, the \"simplified Bishop\" Limit Equilibrium Method (LEM) is used. probability \"Monte Carlo and Latin- Hypercube. These two methods will be used in various 2D and 3D slope stability analyzes in nickel open-pit mine case studies with research parameters including groundwater level and sensitivity analysis. Variables that will influence whether something is safe or not slopes are Slope Height, Overall Angle, and Ground Water Level (MAT). And it is necessary to carry out preventive actions with attention to the drainage system which must be maintained properly. The results of the sensitivity analysis carried out show that cohesion and internal shear angle are variables that have a high level of sensitivity. the tallest. Based on 2D and 3D slope stability analysis in saturated conditions, it was found that the majority of FK values were ≤ 1.2 and PK ≥ 15%. So according to Minister of Energy and Mineral Resources Decree No. 1827 of 2018 in saturated conditions the stability of the existinMining companies engaged in mining activities will inevitably be faced with geotechnical challenges.

So according to Minister of Energy and Mineral Resources Decree No. 1827 of 2018 in saturated conditions the stability of the existing slope is categorized as unsafe. Suggestions for further research are that 2D Slope Stability analysis can be completed with MAT assumptions in Dry, One Quarter Saturated (2H), and Three Quarter Saturated (8H) conditions in the Bintaro Block area.g slope is categorized as unsafe.
