The purpose of this research is to optimize the design of a new technology in the form of turbine that only relies on water flow rate to generate electricity to meet the needs of remote areas. This turbine is simple and has existed in some areas but has very low efficiency. A kinetic turbine is tested its prototype under a laboratory scale to get the turbine efficiency as the turbine performance. The results of this laboratory test will be verified with the turbine modeling implementing the CFD modeling software. In this modeling the observation focus is on the pressure distribution within the blade space which will produce the observation thrust. From the test results of this prototype, it is found that the highest kinetic turbine efficiency is 19% that is on a water flow rate of 45 m3/hour and 80 rpm turbine rotation. From the modeling observations of every 5° runner movement, it appears that there is only one turbine blade that gets the greatest boost or momentum, although at certain runner angle positions there are two turbine blades that get a boost. This condition is suspected as one cause of the low turbine efficiency. From the modeling of this kinetic turbine the highest water pressure in the blade chamber is about 9.19e + 008 Pa, which occurs at 20° runner position, while the lowest pressure is 5.93e + 008 Pa which occurs at 45° runner position. © 2006-2018 Asian Research Publishing Network (ARPN).
