Abstract

In Indonesia, the production of water spinach increased by 9,24% from the last year, which was reasonable because water spinach was one of the most sought-after and popular types of vegetables. The farmers have exposure risk factors of work-related musculoskeletal disorders (MSDs) owing to poor watering of plant workstations using manual methods. This journal aims to explore the application of computer-aided ergonomic analysis and digital human modeling techniques in optimizing the workstations of farmers in water spinach plantations. This paper compares ergonomic scores for body posture farmers before and after improvement. Improvement was done by replacing the manual ball valve with motor operated valve (MOV), controlled (opens and closes) by farmers’ phones. Before and after improvement, body posture farmers are converted to digital human modeling and analyzed by CATIA and RULA analysis tools. The result of this paper comparing before and after improvement results in a percentage reduction in RULA Scores of 75% from a 4 to 1 value.

Abstract

Paving block is constructions material usually used for form wall on building or construction jobs. Quality C dan D paving block manufacture on SMEs Scale in Tasilkmalaya Village does not have proper workplace design so that molder operator work in squat position. Squat position in manufacture paving block process is increasing RULA Score and ergonomic risk for musculoskeletal disorder (MSDs). In previous research, improvement has been applied to workplace, it has successfully increased productivity, but it is not sure can decrease ergonomic risk musculoskeletal disorder (MSDs) and RULA Score. This research aim to identify and compare the RULA Score before and after improvement. Analysis methods is used Rapid Upper Limb Assessment (RULA) with CATIA on moves element which has break down with Theblig methods. The result of research is workplace improvement has successfully decreased levels of ergonomic risk 43%.

Abstract

water spinach Kale is a nutritious food. The Association of Farmers Groups (GaPokTan) Mekar Jaya Mandiri in Cikupa Village, Karang nunggal, has agricultural land planted with watercress as the main source of income. Watering the water spinach plantations is carried out using a piping system with the distribution of water divided into two groups of blocks which is carried out by adding two ball valve mechanisms as a distribution system. The addition of 2 ball valves created problems for the operator. The work cycle when adding two ball valves is 12 body positions in operating the valve, including walking towards the valve, standing straight, and bending when opening or closing the valve. Walking and bending when opening or closing the ball valve takes a long time. Productivity was increased by developing two ball valves with an automatic valve system called the Motor Operated Valve (MOV). MOV uses an albino program for its operating system, and the operator controls M0V via cell phone. Comparison of work cycles between ball valves and those using MOV. The working time cycles for the redesigned operator open and close the valve is 63 seconds with 12 movements. The longest time is walking towards the valve, which is 16 seconds. After the redesign, the operator only needs a cell phone to operate the valve application so that the movement goes to the valve is 0 seconds, and the work cycle time after the redesign is 6 seconds
