| Abstract | Soft soil is common along the coast part of Indonesia and a lot of study for the use of bamboo pile foundation is imposed in Indonesia. They use bamboo piles for the support of embankment in soft saturated soil near rivers or lakes (Suyuti et. Al. 2018 and Rahardjo P., 2014). Some designers use the conventional method in designing a pile in Indonesia (S. Nurdin, et. al., 2018). The conventional method provides a longer time due to the repetitive calculation to determine the optimum design. It is also prone to more errors that may affect the design variables and results. The use of computer codes or programs to obtain the best design of pile and the use of old software such as USACE pile optimization to provide an algorithm for optimization which in limited case. In a real situation, a lot of big projects design a thousand piles and costing millions of dollars and it is a long process and uncertain the methods in optimizing the number of piles (Hurd A. et. al.,2006). The general objective of this study is to optimize the bamboo design foundation using an intelligent algorithm. To test and compare the two methods, a real case study has been studied. The project is named as Kalibaru New Priok Container terminal one container terminal. Two methods were applied to design the pile. First is the use of the conventional method which used the alpha method for clay. The use of the design chart for different pile sizes is imposed to determine the most optimum design. The second method is the use of finite element analysis which uses software to analyze the group pile. The use of Ansys software provides an initial analysis that is connected to the SmartDo software. The SmartDo software provides the optimization method called the recursive conjugate feasible direction method (RCFDM). It manipulates the output and design variables to obtain an optimum value. A comparison of the result is provided and determined that the optimization algorithm can optimize the pile design by 27% from the result in the conventional method. Moreover, the process of an intelligent algorithm reduces the time of iterative calculation |
