The aim of this study was to determine the optimization of a combined Darrieus-Savonius water turbine design with a modified blade position on buckets. To determine the right position of the blade on the buckets, an analysis of the cut plot pressure on the combined turbine was required. The analysis of the cut plot pressure usually uses the embedded analysis in SolidWorks software to improve the combined water turbine design. This research seeks to propose an additional analysis of the cut plot pressure using an image-processing approach. The image processing approach in the analysis of the cut plot pressure was done by clustering image-based segmentation using the Fuzzy C-Means algorithm. The combined water turbine design used the NACA 0018 blade profile and buckets. Modification of the blades’ position on the buckets can improve the turbines’ performance. Three variations of the blades’ position modifications were employed, and three variations of the turbine design were simulated by SolidWorks software to obtain the cut plot pressure, which, in the form of a digital image on each variation, was analyzed using the Fuzzy C-Means algorithm. Variations of the combined water turbine design were analyzed and tested using SolidWorks and MATLAB software. The results of the study indicate that the variations of the blades’ position on the buckets can increase the pressure of the combined water turbine.
