Human activities associated with excavation or landfill will always face problems with slope stability. In case of a surface mining slope, the rocks are subjected to <br /> <br /> <br /> direct contact to the sun, water and climate change. This contact causes weathering or shatter the rocks and another component of the slope which instigate the decreasing strength of the slope. In the end, the slope will completely colapse or failure. The damaging process of the rock by natural influence is ample and varied <br /> <br /> <br /> therefore there is no single experiment that really represents the complex condition of the nature that any particular condition. A particular experiment to <br /> <br /> <br /> obtain rock durability is employing Slake Durability Test suggested by Franklin and Chandra in 1972. In order to obtain Slake Durability Index value, several rock sample were tested in Geomechanic laboratory of Department of Mining Engineering ITB. Meanwhile the uniaxial compressive strength (UCS) and porosity is obtained from secondary data. According to data processing result and graphical data plot, it is revealed that there is a relation between Slake Durability Index and compressive strength where the larger value of compressive strength is obtained from the larger Slake Durability Index of a rock sample. Meanwhile, based on graphs between porosity and Slake Durability Index, it is revealed that there is no relation between the two.
