Analisis Potensi Pemanenan Air Hujan Dengan Teknik Rainwater Harvesting Untuk Kebutuhan Domestik

Abstract

Gampong Leuhan is one of the areas in West Aceh district where most of the people still use ground water as a source of daily necessities. Some people have used artesian wells or drilled wells, but if we look at the cost of manufacture is very expensive. If more use of ground water from the drilling system, then will be inflict an impact of land subsidence. with these conditions, to overcome the problem of the need for clean water and lack of water for people's lives, it needs more effective and efficient system. One of proses is to make rainwater harvesting system from the rooftop of the building/housing by maximizing high rainfall. Field survey indicate building area in Gampong Leuhan already in good condition and livable with dominant house rooftop made of zinc, that this condition will be very maximum in rainwater harvesting process. The analysis of rain harvesting potential in Gampong Leuhan shows 887.892 liters/day, with average rainwater harvesting potential for each house is 862,031 liters/day. The ratio between the total amount of water harvested is 887.892 liters/day with the total use of water for the needs of the people of Gampong Leuhan amounted to 482.346,90 liters/day, indicates that with rainwater harvesting techniques will be sufficient and able to become one of the alternatives in the supply of clean water.

Perancangan Sistem Pemanenan Air Hujan Skala Rumah Tangga untuk Pemenuhan Kebutuhan Air Bersih dan Konservasi Air Tanah

“…Upaya pemanenan air hujan dapat dilakukan melalui media atap bangunan atau permukaan tanah [5]. Penelitian tentang pemanenan air hujan untuk pemenuhan air bersih skala domestik telah dilakukan oleh beberapa peneliti terdahulu [6,7]. Selain untuk pemenuhan air bersih, upaya pemanenan air hujan dapat digunakan APLIKASI TEKNOLOGI untuk mereduksi limpahan aliran dalam sistem drainase [8] dan pemenuhan air dalam pengelolaan pada lahan pertanian [9].…”

Studi Kelayakan Sumber Daya Air Baku Pulau Bintan – Tinjauan Aspek Kuantitas dan Kualitas

“…Curah hujan yang berlimpah di lokasi studi (Pulau Bintan) seharusnya diimbangi dengan kapasitas penyimpanan yang memadai (baik yang bersifat alami atau buatan), agar volume air hujan yang ditampung dapat digunakan untuk memenuhi berbagai kebutuhan (Sallata, 2017;Silvia & Safriani, 2018). Secara alami, kondisi kapasitas penyimpanan Pulau Bintan terhadap hujan yang jatuh cukup rendah.…”

Analysis of meteorological water availability and water demand in Semarang Regency

“…Semarang Regency's Rainfall is around 1000-2000 mm per year which can be used as an alternative for water availability [5]. Utilization of rainwater to fulfill water demand can be done by harvesting rainwater and used it for daily needs [24]. Utilization of rainwater is an effort to conserve water resources because the use of water through rainwater harvesting can reduce the exploitation of groundwater availability [21].…”
