Potential of irrigation channel as the new renewable energy sources

The design and the function of potential energy of the Progo Manggis Channel as an irrigation channel have made the flow discharge is relatively stable throughout the period-even in the dry season. Geographically, the location of Magelang city is relatively up and down and to avoid the erosion, Progo Manggis Channel has been designed to occur in many dams. It is possible to investigate the energy potential found throughout the dams. The production of potential energy is very potential to be used as an affordable alternative energy and environmentally friendly. The measurement of discharge was carried out by measuring the flow velocity and cross-sectional area of the channel. With the aid of current flow meter the discharge measurement was conducted through velocity-area method approach with the total calculation of 510,4303 kW, Kedungsari 61,63076 kW, Menowo 2 55,20043 kW, Menowo 1 114,647 kW, Polosari 80, 67755 kW, Kebonpolo 110,40009 kW, Rindam 21,35771 kW, Jl. Iklas I 25,81356 kW and Jl. Iklas II 40.70273 kW. If at two points of the dump with the highest energy value, a small-scale generator would be built, in accordance with the Ministerial Decree No ESDM. 1122/ MEM/2002 on the Small Scale Power Generation Manual, which states that PT PLN must purchase at 60% of the Cost of Generation in the area to be connected to a low voltage network and 80% connected to an MV network.
