archimedes screw, floating system, analysis, efficiencyAbstract
Archimedes Screw turbine is a type of turbine that generates electricity from water. Initially the archimedes screw turbine was used as a tool to transport water from wells or streams. At present many researchers are starting to see the potential of the archimedes screw turbine to be used as a power plant, because the archimedes screw turbine can work with a small amount of water discharge and has good efficiency at small discharge and low head. In the application of the turbine is placed in the water flow so that the flowing water will pass through the turbine blades. If the water flow overflows it will soak all parts of the turbine so it doesn't work. Therefore this study aims to overcome this by adding a floating system to the turbine so that it continues to work if the flow overflows and also aims to find the turbine variant with the most efficient number of blades by using a water turbine prototype with a floating system using a descriptive method. The results of the turbine blade comparison analysis showed that the turbine with the number of variants of 1 blade was the best variant, with the highest results of rotation, torque, power and efficiency compared to the number of turbines with 2 blades. The turbine with 1 blade produces 510.1 RPM rotation, 0.199 volt voltage, 0.004926 Nm torque, 0.26 watt power and 83.84% efficiency.
