Abstract

Various welding positions and extended durations of welding practice sessions can contribute to Musculoskeletal Disorders (MSDs) complaints among Vocational High School (SMK) students. MSDs encompass conditions that manifest symptoms affecting muscles, nerves, tendons, ligaments, joints, cartilage, and the spinal cord. The implementation of an ergonomic welding table may assist welding operators in working on projects for prolonged periods with a reduced risk of MSDs complaints. This article reports on the community service activities conducted by the Vocational and Mechanical Engineering Education research group at Universitas Sebelas Maret in developing and implementing an ergonomic welding table at SMK Negeri 1 Purworejo. Ergonomic parameters used for reference include the Nordic Body Map (NBM), Rapid Entire Body Assessment (REBA), and Rapid Under Limbs Assessment (RULA). The pre and post experiment analysis indicates a decrease in NBM, REBA, and RULA scores following the implementation of the ergonomic welding table, suggesting the potential for minimizing MSDs complaints.

Abstract

Continuing Professional Development (CPD) for teachers includes self-development activities, scientific publications, and innovative works. Scientific publications are often an obstacle to a teacher's career. Therefore, the skill of writing a scientific paper is a competency that must be possessed by teachers. This community service aims to provide assistance and improve scientific writing skills for Vocational High School (SMK) teachers. The method used consists of a classical approach of holding workshops and individual post-workshop assistance until submitting participant articles to scientific journals. Based on the results of the program, it was found that: (1) the teachers showed high enthusiasm in participating in the program; (2) there is one participant who successfully published his article in the Indonesian Sinta indexed journals; (3) participants who are still in the process and who have already had draft articles still need individual assistance until they can publish into scientific journals. The mentoring program is still needed on an ongoing basis so that writing culture is formed as a part of the CPD program.
