Abstract

The Arcamanik subdistrict, particularly the Cisaranten Kulon neighborhood, is one of the areas in Bandung City that is prone to flooding due to land use changes and inadequate drainage systems. This study aims to analyze the condition and effectiveness of the drainage system on Cingised Street and provide maintenance recommendations to mitigate flooding. The method for calculating drainage channel dimensions uses SWMM 5.2 software with primary data including direct observation and measurement in the field and secondary data in the form of rainfall and planning documents. The evaluation results on Cingised Street, Cisaranten Kulon Village, Arcamanik Subdistrict, showed a significant discrepancy between the existing channel dimensions and the initial planning, with a difference of 61.04% in the S19-S20 (right) segment and 51.43% in the S15-S16 (left) segment. Sediment accumulation reached a total of 294.9 m3 along the 230-meter channel, which significantly reduced its hydraulic capacity. Modeling using SWMM 5.2 identified 8 segments that experienced overflow, causing flooding and standing water. The recommended solution is periodic sediment dredging and channel dimensioning in inadequate segments to restore flow capacity and minimize the risk of flooding.

Abstract

This study examines the drainage system on Jl. Aeromodeling IV, Cisaranten Endah Village, Arcamanik District, Bandung City, which experiences flooding problems due to the suboptimal capacity of the drainage channels. The purpose of this study is to identify, analyze, and provide alternative results from the evaluation of the existing drainage system and planning. The research methods include collecting primary data through observation of the existing drainage conditions and secondary data in the form of regional maps, which are then analyzed using a hydrological approach to calculate the planned discharge and channel dimensions. The results of the study show that there are several points in the drainage system that are unable to accommodate runoff discharge, namely at points P6-P1. The proposed alternative solution is to widen the drainage system at points P6-P1 to increase its capacity in accordance with the planned discharge, as well as to install floodgates and pump houses to transfer water from the flooded area to the receiving river.

Abstract

This study aims to evaluate the performance of the initial retention pond design in the Bandung Inten Housing Complex and to plan for an increase in storage capacity based on the hydrological conditions of the area. The research method refers to the guidelines of the Directorate General of Human Settlements, which include hydrological analysis, determination of runoff discharge, preparation of inflow hydrographs, and calculation of pond storage volume. The evaluation results show that the initial retention pond with a volume 5.400 m3 is not yet capable of accommodating the planned runoff discharge. Based on the calculation results, the required pond volume is 7.509,42 m3 using a pump capacity of 0,03 m3/second, which is capable of reducing the runoff discharge in the Bandung Inten Housing Complex by 81,986%. However, additional alternative control measures are still needed to improve flood control effectiveness.
