Abstract

Sate is one of the Indonesian specialties whose demand is increasing, so the need for skewers is also getting higher. For this reason, innovation is needed to be able to meet these needs. Because when using skewers in a traditional/manual production method, the quality of the skewers produced is not good and the production capacity is also low. Meanwhile, the existing skewer making machine still has some drawbacks. So in this study, a bamboo cutting machine was designed to increase the production of skewers with innovations to cover the shortcomings of existing machines. In this study, the skewer making machine was designed to have a slicing section, a shavings section (making skewers), and a sharpening section. The skewers produced have a diameter between 2.5 mm to 3 mm and a length of 210 mm with a production capacity of 3000 skewers per hour.

Abstract

Welding is a process of uniting two or more materials into a form of connection using heat energy. Friction Stir Welding (FSW) is a solid-state welding method that can produce high-quality welding joints for some materials with low weldability such as aluminum. The research objective was to determine the effect of process parameters on the distortion and resistance of aluminum AA6061-T651 material through the Brinell hardness test. The FSW tool used has a hexagonal pin geometry. The experimental design used the Taguchi method. This study uses 4 factors and each factor has 4 levels, the elements used are tool rotation speed, welding speed, tool tilt angle, and concave shoulder angle. The responses analyzed are distortion and hardness of the welded joint material. The effect of process parameters on the response was analyzed using ANOVA. The results of ANOVA on distortion obtained the value of Brinell hardness in the weld metal area, and in the TMAZ area. Specimen 13 with tool rotation speed parameters of 3022 rpm, welding speed of 43 mm/min, tool tilt angle of 3.5°, and concave shoulder angle of 2° with a distortion value of 0.117°. Then we get the results of the Brinell hardness of the weld metal which is close to the target of the base metal with the parameter tool rotation speed of 3022 rpm, welding speed of 90 mm/min, tool tilt angle of 2.5°, and concave shoulder angle of 8° with a Brinell hardness value of 75. 7 BHN, and the Brinell hardness value at TMAZ with tool rotation speed parameters of 1208 rpm, welding speed of 65 mm/min, tool tilt angle of 2.5°, and concave shoulder angle of 2° with a Brinell hardness value of 74.7 BHN.
