Abstract
The purpose of this research is to find out the best blade profile to increase power of banki water turbine. In this research the blade profile will be made in 5 variants. Variant P1 as a standard and other 4 variant P2, P3, P4 and P5 are the modification profile.The observation focus on output power and flow line contour inside runner of the turbine. The experiment was conducted by CFD software simulation. Head of the water is 5.5 m and discharge 2 m^3/min. Based on the simulation, test result shows that variant P2 is the highest with power increase 10.5 % compare to variant standard P1 and the best flow line countour compare to others.
