The coastal area of DKI Jakarta is predicted to be susceptible to submersion due to rising global sea levels compounded by land subsidence in Jakarta resulting from excessive groundwater usage. Additionally, the continuous elevation of sea levels and extreme weather conditions further contribute to flooding in the coastal region of DKI Jakarta. Based on data from the Regional Disaster Management Agency of DKI Jakarta Province, one of the most flood-prone coastal areas within DKI Jakarta is the Cilincing District. This district is also recognized as a densely populated area where flood mitigation infrastructure is needed around the homes of Cilincing's residents. Hence, an inundation-resistant area with an effective drainage system is imperative. This final project will delve into the Design of Conduit System, Floodgate, and Embankment for the Cilincing Flood Resilient Housing, aimed at supporting the functionality of flood-resistant floating houses in the area. The primary focus of this project is to facilitate the flow of water from the conduit system to a reservoir beneath the structure, allowing the houses to float. Designing the hydraulic engineering involves input from hydrological analyses. The hydrological analysis in this context encompasses calculations of hydrographs and projected rainfall. The results of this hydrological analysis, particularly the hydrograph, will be used as input for the flood modeling in HEC-RAS software, determining the planned flood level to establish the height of the design embankment. In the design of the conduit system, the scope includes determining dimensions for inflow and outflow conduits, the layout of the conduit network, and a pumping system to drain water from the reservoir beneath the buildings. The embankment design entails determining the width, height, type, and gradient of the embankment. As for the floodgate design, the scope encompasses specifying the height, width, and thickness of the floodgate.
