Abstract

The work chair is one of the facilities to support work activities which is very influential to optimize the work of its users. The user in question is a pregnant female employee who works in an office but due to the Covid-19 pandemic, the work is carried out from home (Work From Home / WFH). In the WFH activity, most of them used chairs and sat for a long time. From the observations made, the writer found that chairs that could facilitate pregnant female workers in the home environment were not available, so that the work achieved was not optimal because they experienced discomfort in the lower back caused by changes in body shape. The main objective of this study is to find an ergonomic work chair size for pregnant female employees. The method used in this research is ergonomic analysis through measurement using the anthropometric method from Tilley & Dreyfuss. From the results of the study it can be concluded that the right size to be applied to a pregnant woman's work chair is popliteal height 33 cm, popliteal length 45 cm, butt-elbow height 18,5 cm, toe-to-elbow distance 38,5 cm, lumbar height 20,5 cm, butt-shoulder height 54 cm, normal sitting height 83 cm, lumbar-navel distance 56 cm, hip width 60 cm, hip height 25 cm, and shoulder width 54 cm.
