Improving the Quality of Coffee Shops in Jabodetabek Area by Application and Modification of Coffee Roaster Machine Capacity 400-600 Gram Coffee Beans Using the Reverse Engineering and Engineering Design Method

Coffee roaster machine or commonly called coffee roaster is a tool for cooking coffee beans that have been fermented during the process of cherry coffee into coffee beans in a measured and controlled manner. Coffee shops have constraints in fulfilling the ingredients of the coffee beans themselves by using a roaster coffee machine available at the market less 400 grams or bigger then 1000grams, so that does not match with the needs of the limited ingredients of coffee beans, the coffee shop buys cooked coffee beans at a more expensive price. Therefore, in this research a coffee roaster machine will be designed at the capacity of 400 grams up to 600 grams. Reverse Engineering is a process of analyzing existing products or machine as a reference for designing similar products by minimizing and increasing an excellence product. Reverse Engineering activities have carried out by dismantling and replacing the old coffee roaster. Engineering Designing a new roaster machine, and the last is built a prototype machine. The new design of a roaster machine can produce a faster roasted coffee with the capacity between 400 grams up to 600 grams/77 minutes, in the process of roasting coffee with additional in weight of 200 grams of coffee in a roasted coffee machine after modification.
