<p>Sindang street, which is located in North Rawabadak Sub-district, Koja District, is one of the areas in North Jakarta Administrative City which is an area that is prone to flooding. Even though a working pump house is available, there are still puddles in several places. One of the problems that occur is the channel that drains water into the storage pool narrowing due to sedimentation in the channel. By analyzing the channel using the Log Pearson III distribution method using data obtained from the STA Tanjung Priok Rainfall Station, the rainfall intensity that occurs in a 5 year cycle is 170.748 mm, the Mononobe equation is used to find the intensity of rain per hour that occurs. Then it can be searched for the planned rain discharge using a Rational Method so that it is known that there are 2 channels, namely (P and Q) unable to accommodate the rainfall that occurs.</p>

Abstract The flood disaster that occurred in Pekalongan district in February 2021 was caused by the high intensity of rain for one week with rainfall >50 mm/day and the ebb and flow of sea water due to tides reaching 0.9-1.1 meters. Other problems due to flooding in Pekalongan district are change in land use, land subsidence, waste, erosion-sedimentation, as well as operation and maintenance factors. Losses due to floods cause material and building losses and traffic conditions are paralyzed. The method used in this research is primary and secondary data collection, descriptive qualitative data processing by describing understanding, research approach with field observations. Flood handling that has been carried out is by adding an emergency sliding door to the drainage, procuring a mobile water pump with a capacity of 250 liters/second, a CCSP (Corrugated Concrete Sheet Pile) embankment, rehabilitation of the Bremi River floodgate, construction of a Mrican pump house with a capacity of 8×2 m3/second, and construction of a 2,200 meter long Silempeng earthen embankment. The emergency handling that was carried out during the floods of February 2021 was the opening of the Long Storage Silempeng-Sengkarang and the preparation of sandbags and large sacks for emergency handling.

Pump is a device used to move fluid from one place to another through the pipe media as a channel. The pump has 2 important components in its performance, namely: Impeller and pump house (casing). When the pump cannot meet the required capacity it can use series and parallel pump circuits to increase it. When moving the fluid to a high surface or high pressure it will have the specifications of the head and discharge. Fluid flow is a liquid that flows in a pipe. In flow there is fluid pressure and also flow type. There are 3 flow types, namely laminer, transition, turbulent. To reduce turbulence in the flow can be used Tube bundle which is a device consisting of several pipes that are tied together that are attached to a cross section in the pipe. This research was conducted in 4 testing stages, namely series circuit with additional tube bundle, series circuit without additional tube bundle, parallel circuit with additional tube bundle, parallel circuit without additional tube bundle. Each test takes fluid pressure, discharge, flow type. From the results of this study it was found that the parallel circuit pump with an additional tube bundle produces fluid pressure, discharge, flow velocity smaller than the series circuit, whereas when without additional the parallel tube pump bundle produces a fluid pressure, discharge, flow velocity greater than the circuit series, while for the flow type of this study is turbulent flow.
