Perencanaan Gambar Rainwater Harvesting Metode Roof Cacthment Dengan Desain Tropical Green Roof
Planning Images Of Rainwater Harvesting Roof cacthment Method With Tropical Green Roof Design
RSUD Waluyo Jati melakukan pembangunan terus-menerus guna meningkatkan pelayanan kepada masyarakat. Pembangunan tersebut menimbulkan meningkatnya volume kebutuhan air bersih untuk mencukupi kebutuhan air RSUD Waluyo Jati. Penelitian ini bertujuan untuk mengetahui perencanaan gambar dari sistem rainwater harvesting yang menggunakan metode atap bangunan gedung penunjang terpadu RSUD Waluyo Jati dengan desain tropical green roof dan mengetahui berapa penghematan yang terjadi sesudah diterapkannya sistem tersebut. Penelitian ini menggunakan metode analisis deskriptif dengan pendekatan kuantitatif. Berdasarkan hasil penelitian yang telah dilakukan didapatkan luas total bangunan gedung penunjang terpadu RSUD Waluyo Jati sebesar 656,21 m2 dengan debit limpasan air hujan sebesar 19.260 liter/jam dan intensitas hujan sebesar 30,87 mm/jam. Ukuran ground water tank yang digunakan sebesar panjang 2,31 m, lebar 1,73 m, dan tinggi 2,89 m. Penghematan setelah diterapkannya sistem rainwater harvesting metode roof catchment dengan desain tropical green roof ini adalah mampu menghemat biaya air PDAM sebesar Rp. 156.230/hari.

Waluyo Jati Regional Hospital carries out continuous development to improve services to the community. This development has increased the volume of clean water needed to meet the water needs of Waluyo Jati Regional Hospital. This research aims to determine the planning drawings of a rainwater harvesting system that uses the roof method of the integrated supporting building at Waluyo Jati Regional Hospital with a tropical green roof design and to find out how much savings occur after implementing this system. This research uses a descriptive analysis method with a quantitative approach. Based on the results of research that has been carried out, it was found that the total area of the integrated support building at Waluyo Jati Regional Hospital was 656.21 m2 with a rainwater runoff discharge of 19.260 liters/hour and a rain intensity of 30,87 mm/hour. The size of the ground water tank used is 2,31 m long, 1,73 m wide and 2,89 m high. The savings after implementing the rainwater harvesting system using the roof catchment method with a tropical green roof design is that it can save PDAM water costs of IDR. 156,230/day.
