Analisis dan Desain Bangunan Resapan Air Hujan di Sekitar Jalan Meranti-Tanjung Kampus IPB Darmaga, Bogor

Abstract

Run-off and inundation problem are still common in around Meranti-Tanjung Street, IPB Darmaga, Bogor. The location of the worst inundation was beside CCR building, Faculty of Forestry area, and the road ahead SMA Kornita. Therefore, need a research to reduce the problems of inundation at that location. The purpose of this research is to determine the numbers and dimension of infiltration structure to reduce inundation volume and run-off at the research location with the concept of zero run-off and determines the effectiveness of run-off reduction. The methodology of research is the identification of the problem, literature review, data collection, data analysis, and the plan of design. The results indicate that the magnitude of the total flooding volume in that location is 6 911.47 m3, so it needs the construction of infiltration wells and perforated ditch. Both buildings are based on the calculation of flooding can reduce the total volume of 5 006.25 m3 or 72.43%. Then, the flood volume contribution is not absorbed is expected to be accommodated by the existing drainage channel.
