Laboratory experiments were conducted to measure the shaft power output and overall turbine efficiency. Water turbines with six blades and three different blade shapes (flat blade, twisted blade, and curved blade) were designed and tested to determine the most optimal blade profile. The turbines were tested in a conical basin with an inlet diameter of 600 mm, an outlet diameter of 100 mm, and a height of 800 mm, at flow rates of 0.0088 m³/s, 0.0105 m³/s, and 0.0108 m³/s. The results showed that the turbine with a curved blade profile achieved the highest efficiency, reaching 30,46% at a flow rate of 0.0108 m³/s. Keywords: Turbine, Vortex, and Efficiency
