Nowadays, electrical energy has become a primary need that cannot be separated from human life. The development of industry and technology makes the needs of electricity increase day by day. Obviously, this should be handled by provision of sufficient electricity by operating more power plants. The government has launched a 35.000 MW power plant development program, but it is still dominated by coal energy resources. Renewable energy such as water (hydro) proportion is still very small even though the potential is very big. <br /> <br /> <br /> <br /> This final project consist of Francis turbine design, modelling, and simulation with head 83,71 m and flow rate 1,51 m3/s are expected to produce good performance. The type of blade that is used is NACA 0008 profile and guide vane opening is varied to determine its best efficiency. This design is done to support the development of Pareang Micro Hydropower in Sukabumi district, West Java. <br /> <br /> <br /> <br /> From the result of the design process, modelling, and simulation the geometry of all main components with runner components has 16 pieces of blade. The runner’s blade has a thickness profile of NACA 0008 with a maximum thickness of 15 mm. The phenomenon of cavitation occurs slightly in the guide vane openings above 20 degrees. The maximum efficiency of 93,3 % is achieved at 25o opening of the guide vane with a power of 1,05 MW and at 38o opening of guide vane a maximum power of 1,29 MW is achieved with 82,4 % efficiency.
