Design of Mechanical Roasting Machine using Ergonomic Approach to Increase Productivity of Small Medium Enterprise: A Research at Opak Craftsmen in Sumedang

Abstract

The object of this research is small and medium micro enterprises that make sticky "Opak" with a manual process. The process of ripening food by roasting, where food is placed on a ram wire that is placed on top of the fire stove. The quality of the opaque produced is very dependent on the skills of the employees and the accuracy of flipping through the opaque to obtain good results. In fact, the opaque quality of roasting results varies. Besides, limited production results, causing high demand from customers often cannot be fulfilled by the "Opak" craftsmen. To overcome this problem, the research team designed ripening of glutinous "Opak" with roller method. This sticky rice opaque machine with roller method uses electric power with a low-speed level, so the craftsmen can easily control the maturity level of food ingredients. With the making of the "Opak" sticking machine in the roller method, it is expected that the ripening process can be done with a machine and the maturity level can be uniform; so that the production process is not limited by employee skills; and customer requests can be met.
