ABSTRACK The electrical energy generated from hydropower plants is one source of renewable energy that is cheap, clean and friendly environment. Micro-hydro power plants are usually built in areas that have the potential of generating electrical power in a smaller capacity. Differences in the type - the type of blade on the MHP used in this study sehinnga obtain more effective results with greater rpm, keluarangan voltage, shape or placement of the nozzle position. The method used in this research is to analyze the influence of the model on a turbine blade against the MHP. Blade models used in this study is a semi-circular blade, triangular blade, the blade fins. Rpm speed measurements from the three types of turbines, calculated from 0, 5, 10, 15, 20, 25, 30, 35 and 40. After getting the rpm speed of the three types of turbine torque calculation results are obtained for each - each type of turbine. Data extents extents best to accommodate the flow of water used LAM equation 1, LAM 2, 3 LAM and LAM volume 3. The measurement results that have been done on the study analyzes the effect of the turbine blade models in this MHP, speed measurement results obtained high of 151.6 rpm and highest torque of 0,017Nm at an angle nozzle turbine blade 30 that is on the triangle. As for the area's best water discharge volume is a semicircular blade amounted to 3.19 liters. The results obtained are still low due to a turbine wheel are less able to turn a generator, which the generator torque is greater than the torque on the wheel. It is influenced by a small flow of water in the modeling of micro-hydro power plants this. So in this study is best turbine triangles because triangles obtain optimum rpm and torque are both at an angle of 30, while for the water volume of the blade semicircle best accommodate the flow of water.
