Pengembangan Mesin Bakso Dengan Metode Dfma (Design For Manufacturing And Assembly)

Abstract

DFMA is defined as the design of a product or component that can facilitate the manufacturing process and the assembly process with other components to become a whole product. The process of molding meatballs plays an important role in the production process or economic process. Meatball molding machine has the working principle of stirring the dough by rotating the stirring knife, which is stacked on the shaft that receives rotation of the pulley and gears driven by an electric motor. Meatball dough that is already inside the stirrer will be pushed towards the cutting knife using a stirring knife, then the cutting knife serves to form the meatball dough into meatball granules. The development of a simplified design is needed to increase efficiency and reduce time in assembling meatball molding machines. Design development does not change the function of each product component. The calculation of the efficiency of the assembly of meatball molding machines in Patin Village was carried out at the beginning of the study, then a combination process and component elimination were carried out which did not affect the value added of the product. Meatball molding machines in Patin Village have 24 engine elements with 77 components, requiring 11 minutes 50.47 seconds assembly time and 10.13% assembly efficiency while the engine design development results have 21 engine elements with 64 component components, requiring 8 minutes 5.17 seconds assembly time and assembly efficiency of 12.98%.
