Flood or runoff is a phenomenon that often occurs in Indonesia, especially in DKI Jakarta which is a densely populated urban area that can result in considerable losses in the form of material and fatalities, in order to minimize these losses, more attention is needed. The condition of the cross-section of the Krukut-Cideng River at the condition of Q25=90.79 m3/s there has been runoff on the left bank of the river, so in this case it is necessary to have a handler that can be done by adding the cross-sectional capacity of the river The design flood discharge used is Q25=90.79 m3/s from the calculation of the Nakayasu Synthetic Unit Hydrograph method. The current capacity of the Krukut-Cideng River can no longer accommodate Q25 that enters the river, resulting in runoff on the left bank of the river with the water level being at an elevation of + 1.59 m
