I Wayan Gede Suarjana

Abstract

Objective: LPKA Kelas II Tomohon is a Children's Special Guidance Institution that has the duty and function to foster, guide and protect every correctional student who has problems with the law. One of the coaching programs implemented is welding process training to improve the creativity of correctional students. Every job is always at risk of danger. Likewise in the welding process. Hazards encountered in welding include electric welding machine shock, welding electrode radiation, smoke. An understanding of the important role of ergonomics in every activity must be realized by every worker with a serious effort to participate in implementing it in accordance with environmental conditions. To see a number of aspects of the application of ergonomics, it is necessary to make several visits to LPKA Kelas II Tomohon. During the visit, observations and measurements were made on working conditions, equipment and work facilities in the welding process.

 

Method: The design in this study is an analytical-observational approach, namely observation without intervention to reveal the facts of a cause and effect described descriptively. This research was conducted by observing from aspects of ergonomics. This research is focused on the welding practice training process. Respondents from this study amounted to 14 respondents who attended welding training. This research was conducted on May 2021.

 

Result: Based on the observations and measurements it was found that the welding program was seen from the application of ergonomic aspects, namely nutritional status, work attitude, use of muscle power, environmental conditions, time conditions, working conditions. Social, information conditions and human-machine interaction conditions have been applied, although some aspects still need to be implemented to create safe, comfortable, healthy, efficient and effective working conditions.

 

Conclusion: Most of the ergonomic aspects have been implemented according to the description above in the welding training program conducted by LPKA Kelas II Tomohon, although some ergonomic aspects need to be arranged and adjusted.
