F Foundations are the first and foremost thing to do in a construction site. For building foundations, soil investigation data needed to determine the soil condition or the bearing capacity of the soil at the construction site. Bearing capacity is the ability of the soil under and around the foundation to withstand the loads that acting on the structure above. If the soil cannot bear the foundation load or have a small bearing capacity, it will cause excessive settlement or collapse of the soil. The bearing capacity of foundation and the settlement of foundation could be calculated by the soil investigation data from laboratory test and also field test. In this study, calculations will be made of the pile bearing capacity based on NSPT data on BH-16 and BH-17. The bearing capacity is calculated using variations in pile diameter of 0.4m, 0.5m, and also 0.6m. The result of the test showed the most effective pile so every pile could withstand the load that had been generated from ETABS program model, as well as a relatively similar decrease in tank foundations.
