Abstract
Limited range of fishing areas was one form of loss experienced by fishermen in Indonesia, especially fishermen who still use traditional boats 3 GT capacity. One of the problems with the drive component is the propeller. The propeller was used by fishermen usually. The design of propeller used 3 blades with less than maximum thrust load distribution and fluid velocity. The purpose of this study was to optimize the number of propeller blades in traditional boats 3 GT in capacities with variations in the number of blades 2, 3 and 4. Otherwise, speed used 700 RPM, 1200 RPM, 1700 RPM, and 2200 RPM in velocity. The method used CFD simulations by determining the amount of thrust load and fluid velocity through. The result of optimizing was 2 blades at 2200 rpm in speed whereas generates 2861 m/s in fluid velocity and 1.949 MPa in pressure.
