Abstract: One of the forms of energy that can be harnessed is the energy potential of water, and use the turbine vortex is very useful to maximize the potential. The purpose of this study is to determine the power and efficiency resulting from the broad optimum of the turbine blade reaction flow vortex type of the blade cross-section is straight. This research uses experimental methods, namely by making the turbine vortex type blade section straight that has an area with blade ratio (BR) 0.90, 0.95 and 1. Load variation that is used the increase of 5000 grams to a round shaft on the turbine stops. Testing will be done to get the power and efficiency of the vortex flow. The highest power generated by the turbine with blade ratio 0.90, which occurs on the capacity of 12,341 L/s with a loading 40000 grams, has a power of 44,44 watts. The highest efficiency is produced by the turbine with a blade ratio 0.90 which occurs on the capacity of the 10,803 L/s with a loading 45000 grams, has an efficiency of 53,82 %.
