title: Ergonomics work stations decreases the health impairment and saves electrical energy at the woodworking workshop in Bali, Indonesia.
abstract: This research was conducted to assess the positive effect of the ergonomics work station on the health impairment and electrical energy usage at the woodworking workshop in Bali, Indonesia. Woodworking workshops are dangerous, particularly when they are used improperly. Workers are exposed to health hazards that cause health impairment and inefficiencies in their work conditions. A preliminary study at a woodworking workshop at the Bali State Polytechnic showed that the work station was not suitable to body size of the participants and caused awkward postures. In addition, there was also an inappropriate physical work environment. Both inappropriate work station and physical work environment caused participants to be less active and motivated. This paper reports on an experimental study into the effects of an ergonomic intervention at this workshop. The participants were 2 groups of male students with 10 participants in each group. The first group performed the task with the original work station as a control group, while the second group performed the task with the new work station. The study found a significant difference between groups (p < 0.05) both for the health impairment and the electrical energy usage. The ergonomics intervention on the work station decreased the working heart rate (16.7%), the total score of musculoskeletal disorders (17.3%), and the total score of psychological fatigue (21.5%). Furthermore, it also decreased the electrical energy usage (38.7%). This shows that an ergonomics intervention on work station decreased the health impairment and saved electrical energy usage. It also protected the workers from woodworking hazards and allowed participants to perform their tasks in healthy, safe, convenient and efficient work conditions.
