Savonius is a turbine with a simple construction and good initial torque that has become a promising technology for generating electric power. However, the efficiency of the turbine still needs to be improved. Therefore, the proposed study was conducted to enhance the Savonius turbine's performance with additional s/r (straight profile) and l/r (blade end). Rainwater harvesting was used as an experiment with only gravitational potential energy. The resulting power output, coefficient of power, and rotational speeds were used to evaluate the turbine's performance. The additional s/r was used to direct the water before hitting the concave turbine, and the additional l/r was used to catch the energy stored in the water in a more optimum manner. Based on the results, an additional blade end (l/r) of 0.6 and a straight blade (s/r) of 0.75 produced the best performance with 0.29 Cp, 1023 rpm of rotational speeds, and a maximum power generated of 60.8 W.

bread is one of the alternative staple foods that is quite in demand by the public. This has resulted in the bread making industry being enthusiastically welcomed by business people because it has bright and open opportunities for large and small scales. However, the Micro, Small and Medium Enterprises (MSMEs) industry is unable to compete. One of them is because of the use of technology in the dough kneading process. This research aims to make a product plan for a horizontal type of bread dough mixer for MSMEs using the Design for Manufacturing and Assembly (DFMA) method and Quality Function Deployment (QFD) analysis where the design is based on design, materials, analysis, and equipment and manufacturing process planning. In this study, the action research method, engineering and the Solidwork simulation design software were used. The design of the machine can be used for a stirring capacity of 10 kg and a rotation speed of 40 rpm. The results of the design consist of several main parts, namely the main frame, container, stirrer, motor, and transmission system. DFMA; manufacturing; dough mixer machine; horizontal stirrer
