More than 40% area in Jakarta is below mean sea level which it causes inundation to occur every year in Jakarta. In order to solve this problem, the government developed Jakarta flood control management. Polder system is one of drainage system for areas that cannot drain water by gravity. There is one polder system located at North Jakarta named North Sunter Polder System. However, the inundation still occurs every year in that area. Based on the problem, the aim of this study is to analyse the cause of flood inundation in the area, it can be known by simulation using the HEC-HMS and HEC-RAS applications. Based on the simulation results it is known that the cause of flood inundation in the North Sunter Polder system is due to the less optimum pump operation in the polder system. So that to overcome the flood inundation can be done by increasing pump capacity and changing the pump operating elevation.
