Abstract

Coffee roasting machine innovation using a gas stove heating system. This machine still has a drawback, namely the previous roasting machine did not have optimal air circulation that was able to regulate the roasting tube room temperature, so users did not know the roasting tube room temperature. The design to be made has the advantage that it has an automatic shutdown control system. The capacity of this machine is also greater than the capacity of the previous engine, with a capacity of 3 kg. After the roasting process, the coffee can be removed from the roasting pan easily. For this reason, the planning of the roasting machine was administered through an ergonomic approach in one short case study with a pre- and post-test design group which was administered observationally on the roasting process manually and by employing a roasting machine. Ergonomic Roast Machine specifications are designed with a capacity of 5 Kg as follows: a). The roasting tube may be a chrome steel plate with a thickness of 1.2 mm with a length of 670 mm and a width of 310 mm, b). the facility of the electrical motor is 0.25HP with a rotation of 1400 rpm while the rotation of the drum roast is 50 rpm with a gearbox transmission, c). the size of the machine are 80 cm long, 75 cm wide and 90 cm high. Ergonomic test results show that the utilization of a roasting machine can increase the work productivity of roasted by 62.07%.
