Abstract

In this article, a kind of green composite was prepared from recycled polypropylene (r-PP) which was further reinforced with various loadings of chemically modified bamboo fibres. Effects of bamboo fibre loading on the mechanical and thermal properties of r-PP/bamboo composites were studied. Those properties were characterized by tensile testing, impact testing, thermogravimetric analysis (TGA), and differential scanning calorimeter (DSC). Standardized test specimens with 0%, 10%, 20%, and 30% mass fractions of bamboo fibre were obtained by an extrusion process which was then finalized on injection molding. The experiment revealed the tensile strength and strain of the composite become greater with the increase of bamboo fraction in the ultimate value of 20% mass fraction. The composite with 10% bamboo fibre loading recorded the highest value of impact strength. Meanwhile, it was evident that the presence of bamboo fibre decreased the thermal stability of recycled polypropylene materials. Therefore, this composite material may find good potential for semi-structural loading applications in relatively low-exposure working.

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.
