Abstract: The horizontal shaft Pelton turbine test bed is designed to meet the needs of practicum facilities to improve understanding and research on energy conversion and utilization of renewable energy. One of the stages in the design of the test bed is the design of the turbine bucket. This research has the aim of obtaining a bucket design that is in accordance with the design of the test bed system, considering that the turbine bucket is a crucial part in energy conversion and is under heavy working conditions, so a good design is needed. The application of structural analysis is one way to obtain a more optimal bucket design. This is the main focus of this research. The structural analysis method used is Finite Element Analysis (FEA). FEA is applied to three bucket design geometries that have been designed using Inventor software. The structural strength analysis was carried out with the help of ANSYS software. The analysis obtained data on von-Mises stress, von-Mises strain, factor of safety (FOS), deformation, and life of the three existing bucket designs. Furthermore, the results of the analysis were compared and it was found that the most optimal geometry for the designed turbine test bed was geometry 3. Where geometry 3 has the lowest maximum von-Mises stress at 9.4105 MPa, the lowest maximum von-Mises strain with a value of 0.013562, has the highest minimum FOS with 2.7629, has the smallest deformation with 0.66054 mm, and has the highest minimum repetitive loading ability with 100,000,000 cycles before the risk of structural failure can occur. Therefore, Design 3 geometry is selected as the bucket geometry for the designed turbine test bed system.
