Abstract: Polder system is a solution for flooding in urban areas where the ground level is lower than the water level of the receiving water body. The effectiveness of the elements such as dike, river channel, pond, drainage canal, and pump station greatly affect the performance of a polder system in controlling water level inside the system. The flood problems that always occur in Jakarta caused damages and losses are the background to conduct an evaluation presented in this paper. Jakarta is the capital city of Indonesia, where the northern part of Jakarta is divided into 43 polder systems and one of them is Muara Angke Polder. This study specifically addresses the Muara Angke Polder system performance. Solving the problem of flood in Muara Angke area should be based on the performance of the existing polder system as one of the flood control elements. This study emphasizes on evaluating the existing Muara Angke Polder system in controlling the flooding. Muara Angke polder catchment area is around 1.46 km2. Daily rainfall data from Kemayoran Station is used to estimate the design flood. Using WinTR-55 model, the performance of polder system is evaluated by comparing the capacity of existing drainage canal, pump and pond to the design flood. The result shows that existing pump and pond capacity in some sub-catchments are inadequate to accommodate the design flood, where the effectiveness is less than 50 %.. The water queue causes overflow in the drainage canal and then flooding in the Muara Angke area is unavoidable.
