The Effectiveness of Coffee Bean Processing Machines in the Rezeki Farmers Group in Takengon, Central Aceh

The appropriate technology program in the Community Service Scheme of Science and Technology for the community entitled "Effectiveness of Coffee Bean Processing Machines in the Rezeki Farmers Group in Takengon, Central Aceh" is to assist partner communities in efforts to improve UD Rezeki Group productivity through the application of appropriate technology and training in product diversification skills. coffee preparations. The method in implementing the Community Service Program consists of three activities, namely (1) making Coffee Roasting machines, flour and packaging, (2) training in processing skills for types of coffee beans, Arabica and Robusta and (3) Coffee Packaging Systems. The purpose of this Coffee Grinder Machine Design activity can facilitate the work in large-scale coffee milling. The methods taken in this design include: the survey stage, the planning stage, the implementation phase, post-construction and report making. Through engine performance test results obtained as follows: 70-watt wiper motor capable of rotating a load of 10 kg with a 72 rpm rotational speed. Gear transmission can reduce rotation from 180 rpm to 72 rpm. The temperature control unit can regulate temperatures from 500 C to 2500 C, while the rotation speed control unit can set the speed from 10 rpm to 72 rpm.
