Ergonomic Improvement of Drinking Water Dispenser for Indonesian People Using Rapid Upper Limb Assessment Method

Abstract

The existing water dispenser has been established in Indonesia for years which has various water tap designs and height levels as well. Unfortunately, the existing water tap design and height level have suited only for certain people with a height of less than 167 cm and therefore other taller people experienced bending posture when operating it. Furthermore, the water tap valve which required both hands to operate has made another effort to fill into the water media. Several research and methodologies have been proposed regarding water tap such as how to avoid water spills using the TRIZ method and how to enhance the smart dispenser through the Internet of Time. None of it discovered how to enhance its ergonomic aspect. However, to achieve improve the ergonomic level, several experiments and measurements have been performed in this research using Rapid Upper Limb Assessment (RULA) method, to generate a recommendation for ergonomic water dispensers.
