Pile bearing capacity can be obtained from static and dynamic approaches. Calculation of the carrying capacity of the pile statically is by approaching it through the technical properties of the soil. Meanwhile, the dynamic method is to analyse the ultimate capacity with data obtained from pile driving data. The research was conducted using calendaring data to get the carrying capacity ratio based on a dynamic approach. Carrying capacity based on calendaring data is calculated using five methods, namely Hilley, ENR, Danish, and Navy-Mc.Key, and Janbu. The results of these calculations, then a coMParison of the ratio to the carrying capacity of the PDA test is carried out. The research was carried out at two locations: the Gempol-Pasuruan toll road construction project and the Widuri Bondowoso Bridge. The results of the calculation of the carrying capacity for the ultimate Q at the Gempol-Pasuruan toll road location, the Danish method, which is close to the PDA test results with a ratio of 1.1132 (P1-2) 0.8911 (P3-5), for Qijin at the Gempol-Pasuruan toll location, the method Danish is close to the PDA test results with a ratio of 0.7421 (P1-2), 0.5940 (P3-5). The calculation results for the ultimate Q at the Widuri Bondowoso Bridge location, the ENR method is close to the PDA test results with a ratio of 1.7260 (P1-19), 1.2553 (P2-17), for Qijin at the Widuri Bondowoso Bridge location. This Hilley method is close to the PDA test results with a ratio of 1.0489 (P1-19), and 0.7625 (P2-17).
