Abstract
Kelangkaan air, yang diperburuk oleh pertumbuhan penduduk, perubahan iklim, dan kualitas air yang buruk, memerlukan pasokan air yang berkelanjutan, pencegahan kekeringan, keseimbangan ekologi, dan perlindungan lingkungan. Tingginya permintaan air di Pondok Pesantren Terpadu Al Kahfi merupakan hasil dari populasi siswa yang besar dan perubahan kebiasaan penggunaan air. Air tanah telah menjadi sumber utama, tetapi ekstraksi terus-menerus dapat menyebabkan penurunan tanah. Pemanenan air hujan merupakan solusi yang efektif untuk mengatasi masalah air, terutama di Kabupaten Bogor, di mana sekolah tersebut menerima curah hujan tahunan 2500-5000 mm. Penelitian ini menyelidiki kualitas dan kuantitas air hujan dan air tanah di Pondok Pesantren Terpadu Al Kahfi. Sampel air hujan dikumpulkan dari atap asrama dan sampel air tanah dari keran terdekat. Jumlah potensial air hujan yang dikumpulkan dihitung dengan menggunakan curah hujan harian, daerah tangkapan air, dan koefisien limpasan. Permintaan air bersih warga dibandingkan dengan jumlah potensial air hujan. Dimensi talang air ditentukan dengan menggunakan tabel dari SNI 03-7065-2005 setelah memperoleh data intensitas curah hujan. Hasil uji laboratorium menunjukkan bahwa air hujan yang ditampung dari berbagai talang air hujan secara konsisten melampaui batas mutu air minum untuk parameter E. Coli dan total coliform. Pada interval tertentu, air hujan menunjukkan tingkat pH rendah, kekeruhan tinggi, warna keruh, dan kadar mangan serta kromium tinggi. Hujan di Pondok Pesantren Al Kahfi diukur dari segi intensitas hujan. Intensitas hujan yang diamati di area santri putra berkisar antara 84,1 mm/jam hingga 179,73 mm/jam. Sedangkan untuk area santri putri berkisar antara 59,11 mm/jam hingga 160,59 mm/jam. Persentase estimasi air hujan yang dapat digunakan sebagai air minum alternatif untuk bangunan A, B, C, D, E, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, dan V berdasarkan periode satu dekade adalah 87%, 68%, 77%, 47%, 60%, 61%, 45%, 44%, 51%, 46%, 68%, 54%, 53%, 62%, 113%, 82%, 82%, 94%, dan 50%. Sistem pemanenan air hujan diusulkan untuk semua bangunan asrama, kecuali Usaid, Maria Qibtiyah, Aisyah, dan Khodijah. Air hujan yang terkumpul ditampung dalam bak-bak dengan kapasitas masing-masing 12 m3, 8 m3, 10 m3, 3 m3, 11 m3, 15 m3, 8 m3, dan 5 m3 untuk gedung asrama A, B, C, D, E, G, H, dan I. Sedangkan untuk gedung K, L, M, N, O, P, Q, R, S, T, dan V masing-masing 4 m3, 4 m3, 4 m3, 11 m3, 10 m3, 5 m3, 10 m3, 5 m3, 5 m3, 5 m3, dan 3 m3. Air hujan tersebut akan diolah dengan menggunakan filter karbon aktif dan ozonisasi. Selanjutnya air tersebut ditampung sebentar di tandon tanah sebelum dialirkan ke PDAM. Total anggaran biaya estimasi perancangan sistem pemanenan air hujan di Pondok Pesantren Al Kahfi adalah sebesar Rp. 1.080.000,00

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
