Ergonomics and Anthropometry in the Design of Doyo Leaf Fiber Softener Machine

Abstract

One of the production processes for making weaving from doyo leaf fiber is the process of softening the dry leaf fiber before it is spun into yarn. This softening process is done so that the dried leaf fibers become more flexible and elastic so they can be easily spun into yarn. One aspect of machine design is reviewing machine design from ergonomic factors so that the machines used by workers are safer and more comfortable. This study aims to design a doyo leaf fiber softener machine in terms of the ergonomics of the machine's products. The analysis used in this study is an ergonomic analysis using anthropometric data tables using the sex of adult women, aged 18-45 years with a size of 50 percentile, from the Indonesian ethnic group. The results of the analysis show that the ergonomic machine height for workers is 100 cm, with a width of 100 cm and a machine height of 70 cm. The contribution of this research is to provide a design and build of doyo leaf fiber softener machine to the softener machine manufacturing industry so that the machine becomes ergonomic for the safety and comfort of the user.
