Abstract :
The jetty at the PLTU serves as a place for the distribution of the main fuel and leaning of a large vessel with coal. The jetty needs a strong foundation so that it can receive a large load on top , withstand horizontal force from leaning the ship and support buildings with strong soil layers located deeply. In this study will be compared the results analysis of the bearing capacity of steel pile foundations in jetty buildings using static formulas and dynamic formulas. In the static formula, Meyerhoff's method is used which uses SPT data, while the dynamic formula uses the Hiley, PCUBC, and Janbu methods which use calendering data. Based on the analysis results obtained Qijin Meyerhof amounting to 22,195,697 kN, Qijin Hiley amounting to 15598,443 kN, PCUBC Qijin amounting to 22,448,195 kN and Janbu Qijin amounting to 9693,117 kN. while based on the results of comparison analysis, Meyerhoff's results were 29.723% higher than Hiley's, PCUBC was 1.125% higher than Meyerhoff and Janbu was lower than Meyerhoff at 56.332%. From the analysis results obtained Qijin dynamic formula that approaches Qijin static formula Meyerhof method is Hiley Qijin.
