Abstract

In Karangasem Regency, roasted grated coconut is usually used as a way of kit for religious ceremonies. Roasted grated coconut is traditionally made employing a gas range or burning stove with a production capacity of about 1.5 kg of grated coconut. the typical daily production is around 6 kg, therefore the process of roasting grated coconut is repeated. This roasting process is administered for a mean of 90 minutes for one production. During the roasting process, the craftsmen stir the grated coconut continuously, and sometimes because they feel tired, the stirring process gets slower in order that there are parts of the grated coconut that get charred this causes the standard of the roasted grated coconut to be less good. In efforts to beat these problems, a working mechanism is required with the assistance of a roasting machine, in order that it can make it easier for craftsmen within the roasting process, reduce fatigue, reduce workload, and may increase work productivity. 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 grated coconut craftsmen by 62.07%.
