Design of rapid desiccated air-tray dryer machine with ergonomic approach

Abstract

Occupational Health and Safety is one aspect of increasing work productivity. Increased productivity can be obtained when machine tool operators feel safe and comfortable operating the machine. The study aimed to evaluate the design of a rapid desiccated air-tray dryer using an ergonomic approach with anthropometric methods. Anthropometric data used in the design include shoulder height in standing, arm length when stretched forward, and arm length when stretched sideways. The data obtained were processed and tested for uniformity, data adequacy, and determining percentile. The study results, the length of the existing 170cm machine is close to the recommended size of 175 cm (length of the arm to the side of P50). The height of the existing desiccant tank is 170.9 cm more than the recommended 123.55 cm (shoulder height P5), the height of the existing drying cabinet is 155 cm. Higher than recommended 123.55 cm (shoulder height P5), the door is too wide 72.8 cm. In comparison, side arm span (P5) 64.5 cm, engine setting in squat position (55 cm). a solution that can be done by making a ladder for the process of inserting the desiccant so that the legs can rest higher; make two cabinet doors so that the span of the hands is not too wide; drying cabinet rack and machine setting box are changed to 123.55 height according to shoulder height for comfort when working.
