Utilization of the Kelekar River Flow as Micro-Hydro Power Plant

The number of rivers scattered throughout Indonesia can certainly be used as an alternative energy source, one of which is micro-hydro power plants, it is a power plant that uses water resources on a small scale as a turbine drive to produce electrical energy, where the generation of this energy is influenced by water discharge and the height of the water fall. One of the rivers that has a fairly large water discharge is the Kelekar River which is located in the Ogan Ilir Regency area. To calculate the amount of energy generated from the Kelekar River, a prototype micro hydro power plant is designed, then the energy generated from the simulation of the tool will be used as the basis for designing a micro hydro power plant based on actual conditions. From the analysis of water discharge and water fall height based on the condition of the Kelekar river, the design of the tools is obtained as follows: (i) the dimensions of the fast pipe are 0.8 m, (ii) the thickness of the fast pipe is at least 4 mm, (iii) the effective energy height is 3.476 m, (iv) the dimensions of the runner are 0.65 mx 1.50 m, and (v) the power generated is 11.508 kW.
