Abstract

Water scarcity, exacerbated by population growth, climate change, and poor water quality, necessitates sustainable water supply, drought prevention, ecological balance, and environmental protection. The high demand for water at Al Kahfi Integrated Islamic Boarding is a result of its large student population and changing water use habits. Groundwater has been the primary source, but continuous extraction could lead to land subsidence. Rainwater harvesting is an effective solution to address water issues, especially in Bogor Regency, where the school receives 2500-5000mm of annual rainfall. The study investigates the quality and quantity of rainwater and groundwater at Al Kahfi Integrated Islamic Boarding School. Rainwater samples were collected from the dormitory roof and groundwater samples from the nearest tap. The potential amount of rainwater collected was calculated using daily rainfall, catchment area, and runoff coefficient. The clean water demands of residents were compared with the potential amount of rainwater. Water gutter dimensions were determined using table from SNI 03-7065-2005 after obtain rainfall intensity data. The laboratory tests showed that the rainwater collected from various rainwater gutters consistently surpassed the drinking water quality limits for both E. Coli and total coliform parameters. At certain intervals, it exhibits low pH levels, high turbidity, coloration, and elevated levels of manganese and chromium. The rain at the Al Kahfi Islamic boarding school is measured in terms of rain intensity. It was observed that the rain intensity in the male student area ranged from 84.1 mm/hour to 179.73 mm/hour. The range for the female student area is 59.11 mm/hour to 160,59 mm/hour. The estimated percentage of rainwater that can be used as an alternative drinking water for buildings A, B, C, D, E, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, and V based on period of one decade are, 87%, 68%, 77%, 47%, 60%, 61%, 45%, 44%, 51%, 46%, 68%, 54%, 53%, 62%, 113%, 82%, 82%, 94%, and 50% respectively. A rainwater harvesting system is proposed for all dormitory buildings, except Usaid, Maria Qibtiyah, Aisyah, and Khodijah. The collected rainwater is stored in tanks with capacities of 12 m3, 8 m3, 10 m3, 3 m3, 11 m3, 15 m3, 8 m3 and 5 m3 respectively for dormitory buildings A, B, C, D, E, G, H, and I. while for buildings K, L, M, N, O, P, Q, R, S, T, and V respectively 4 m3, 4 m3, 4 m3, 11 m3 ,10 m3, 5 m3, 10 m3, 5 m3, 5 m3, 5 m3 and 3 m3. The rainwater will be treat by t using activated carbon filter and ozonation. Subsequently, the water is briefly kept in ground reservoir prior being sent to the tap. The total estimation cost budget for designing a rainwater harvesting system at Al Kahfi Islamic Boarding School is IDR 1,080,000.00
