EVALUATION OF DRAINAGE SYSTEM IN CEMAKA SLUM IN FLOOD EVENTS IN 2021

Abstract


Early in 2021, South Kalimantan experienced a major flood disaster caused by high rain intensity. Badan Nasional Penanggulangan Bencana (BNPB) reported that as many as ten regencies/cities experienced flooding in South Kalimantan Province, one of which was Banjarbaru City. One way to reduce flooding and inundation is to have a good, economic, and appropriate drainage system. The ability of the soil to infiltrate downstream influences the design of the drainage system. Soil absorption capacity can be measured by infiltration rate experiments. This study aims to analyze the rate of infiltration in the Cempaka Slum Settlement, Cempaka District, Banjarbaru City. The data used in this study are infiltration rate measurement data collected in the field using a double-ring infiltrometer (Turf Tec Infiltrometer), which is processed using the Horton method. Based on the results of the analysis of the inlet filtration rate in the Cempaka Slum Settlement, it was determined that the overall average inlet filtration capacity in the Cempaka Slum Settlement was 94,950 cm/hour with a very fast filtration rate classification.
