Ergonomic and Anthropometric Analysis of Conventional Coffee Bean Grading Machines

Abstract

Indonesia is one of the largest coffee producers in the world. According to statistics from the
International Coffee Organization (ICO), Indonesia is the 3rd largest coffee producing country,
after Brazil and Vietnam. There are several types of coffee, among others, types of arabica coffee
(Coffea arabica) and robusta coffee (Coffea robusta). The objectives of this study are as follows:
Knowing the physical working environment conditions in the use of a coffee grading machine,
analyzing the compatibility of machine dimensions with operators, Knowing the load
classification work received by the operator. The method used in this research is a comparative
descriptive method, which is to compare the actual performance of the coffee grading machine
with the initial condition of the machine according to the engine modification specifications.
Meanwhile, the physiology and physical environment aspects of coffee assessment are based on
ergonomically determined standards. In this study, researchers will analyze the anthropometric
analysis of machines and operators (height of shoulders when standing and arm length). Work
physiology (classification of workload based on pulse energy consumption, oxygen consumption)
