The aim of this research was to improve the performance of vortex turbines by testing the performance of vortex turbines using experimental methods, with test variables including blade tilt, flow speed, and vortex turbine impeller material using PLA (polylactic acid). Tests were conducted on a laboratory-scale gravitational water vortex turbine (GWVT) with a pool diameter of 1 meter and a height of 0.8 meters. The test results showed that the turbine with 5 blades produced a maximum torque of 5.89 Nm and an efficiency of 51.10%. The turbine with 7 blades produced a maximum torque of 7.85 Nm and an efficiency of 58.51%. The highest efficiency, 64.69%, was achieved by the 9-bladed turbine, which also had a maximum torque of 8.83 Nm. Experimental tests showed that this laboratory-scale vortex turbine achieved a maximum power output of 87.28 watts, with an efficiency of 56.66% and a torque of 9.81 Nm, using a 9-bladed turbine at a water velocity of 2.5 m/s. These results certainly show an improvement compared to previous reference studies, where the use of materials with lower density, higher blade angle, and larger blade geometry can improve the performance of vortex turbines.
