    A picohydro power plant is one of renewable energy solusion which could be utilized by watershed people, as a low cost sustainable power plant. The turbine type that could be apply by utilize the low of water flow capacity and water high fall is thread turbine. More over the thread turbine could be simply manufacturing and low maintainance and operational cost. This research objectives are to find out the torsion force value and turbine shaft rotation which could be generated by 5 blades thread turbine using variation on inclination shaft and water flow discharge. This thread turbine with 76 mm inside diameter and 120 mm outside diameter, 200 mm pitch design was tested in Lubuk Minturun River, Padang, West Sumatera with testing variables are 30o and 45o turbine shaft inclination angel and 0.01633 m3/s through 0,01824 m3/s water flow discharge variation. The research result are : the highest turbine torsional force is 1,88 Nm and 601 rpm shaft rotation were gained at 0,01824 m3/s water flow discharge and 30° of turbine shaft inclination angel. By that research, it was estimate that 118,25 watt turbine power could be gained with 88,23% in efficiency, in which by that electrical power value it could be utilized as sustainable power plant by surround community hopefully
