Abstract

Sudajaya Hilir Village, Baros District, Sukabumi City, is one of the areas prone to flooding due to drainage capacity and land use changes. This study aims to evaluate the condition of existing channels and analyze their capacity using the EPA Storm Water Management Model (SWMM). The data used includes field surveys on the dimensions and condition of the channels, historical rainfall data, and drainage planning documents from the Sukabumi City Public Works and Spatial Planning Agency. The evaluation results show that the dimensions of the existing channels are not in accordance with the plan. The SWMM simulation identified points 1 to 5 along Jalan Lingkar Selatan. The difference in size between points 1 and 5 ranged from 0.05 to 0.20 meters. The SWMM simulation identified points 4 and 5 as having low elevations. Based on the simulation results, recalculations were performed to reduce the potential for flooding in the area. The recommended measure is to increase the width of the drainage channel at points 1 to the outfall by 0.1 to 0.4 meters. In addition, the construction of a retention pond at locations with lower elevations is also recommended to accommodate excess water discharge. With a combination of channel dimension improvements and the provision of retention ponds, the capacity of the drainage system is expected to increase, thereby reducing the risk of flooding more effectively.

Abstract

Lembursitu Subdistrict is one of the areas in Sukabumi City that often experiences flooding, especially during the high-intensity rainy season. This study aims to determine the priority of flood management in six affected locations spread across four villages. Priority assessment was carried out using a weighting method based on six parameters listed in the Minister of Public Works Regulation No. 12 of 2014, namely flood height, flood area, flood duration, flood frequency, economic losses, social and government facility disruptions, transportation losses and disruptions, housing losses, and private property losses. The research data was obtained through field surveys, community interviews, and secondary data from relevant agencies in Sukabumi City. The weighting results showed that the location with the highest priority for handling was L6 (Jl Raya Palabuhan II) with a score of 297.5, followed by L5 (Jl Merdeka) and L1 (Jl Merdeka). These three locations have a major impact on social, economic, transportation, and public service facility activities. These findings provide a basis for local governments to determine more effective flood management strategies, particularly through increasing drainage capacity, channel normalization, and the implementation of a sustainable eco-drainage-based flood control system.
