Ergonomic Working Design Model in Reducing Fatigue due to Air Traffic Control (ATC) at Kuala Namu Airport, Indonesia

Abstract

Generally, humans can work properly and achieve optimal results when supported by good environmental conditions. The effect associated with the inconvenience of the working environment can be experienced over a prolonged period. Therefore, this study aims to determine the ergonomic working design model in reducing fatigue due to Air Traffic Control (ATC) at Kuala Namu Airport, Deli Serdang – Medan, Indonesia. This is because it is necessary to consider the physical condition or health conditions of controllers to enable the company to extend its services' life and profitability. Rapid Upper Limb Assessment (RULA) is the research method used to investigate upper limb disorders. RULA was developed as a method to detect posture, which is a risk factor. This method is designed to assess workers and determine the musculoskeletal loads likely to disrupt upper limbs. Under such conditions, the management is advised to develop 'open management' based on political will, which involves operators in every step of the improvement, because they have adequate ideas of the problems at hand. Participation in ergonomics enables employees with their supervisors and managers to apply adequate knowledge in their workplace to enhance working environment conditions.
