Generally, humans can work properly and achieve optimal results when supported by good environmental conditions. The effect associated with the inconvenience of working environment be experienced over a prolonged period. Therefore, this study aims to determine ergonomic design model in reducing fatigue due Air Traffic Control (ATC) at Kuala Namu Airport, Deli Serdang – Medan, Indonesia. This is because it necessary consider physical condition or health conditions controllers enable company extend its services' life profitability. Rapid Upper Limb Assessment (RULA) research method used investigate upper limb disorders.
