Abstract

Saat pompa air DC sudah banyak diproduksi, namun masih jarang digunakan masyarakat umum. Penggunaan dengan arus DC sangat potensial karena dapat menggunakan listrik langsung dari panel surya, akan tetapi masyarakat umum belum mengetahui keandalan pompa tersebut. Untuk mengetahui keandalan pompa tersebut, dilakukan kajian ini. Berdasarkan pengujian yang dilakukan untuk mengetahui ketahanan pompa menggunakan pompa DC dengan spesifikasi sebagai berikut: daya masimum 180 W, head maksimum 15 m, kapasitas maksimum 1,5 m3/jam dengan 12 V. Dari hasil pengujian selama 5 x 24 jam dengan head 4,9 m diperoleh hasil yaitu pada voltage 12,04 V dan 4,09 A didapat kapasitas pompa yaitu 23 liter/menit, daya pompa 50,7 W. Pada tegangan 7,7 V dan 6,02 A didapatkan kapasitas pompa yaitu 10 liter/menit, daya pompa 46,4 W. Pada tegangan 12,06 V dan 4,1 A didapatkan kapasitas pompa yaitu 20 liter/menit daya pompa 49,4 W. Sehingga dapat diambil kesimpulan bahwa dari hari pertama sampai hari ke tujuh, performa pompa dapat dinilai hanya mengalami sedikit perubahan dari 23 liter/menit menjadi 20 liter/menit.

Abstract

The utilization of water as a natural resource from renewable energy for power generation is an alternative solution to replace the need for fossil fuels. In Girimulyo village, Ngargoyoso sub-district, there is a river that can be potential to become a Micro Hydro Power Plant. From field observations and calculations using the GPS (Global Positioning System) application, the water discharge Q = 0,2 m3/s. and the height of the waterfall H = 16,5 m. Based on the height and the existing water flow, it is determined that the turbine used is the Pelton turbine. From the calculation of the effective head of 15,81 m. With the water discharge used to rotate the Pelton turbine, the power obtained is 20,162 kW. From this power, it can be calculated that the shaft diameter is 38 mm. To make it easier to adjust the rotation between the generator and the Pelton turbine rotation, a flat belt type belt transmission with a width of 300 mm and a thickness of 9 mm is used while the maximum belt tension is 39 kg with a tangent angle between the pulley and the belt 7,180.
