Analisa Beban Kerja Mental dengan Metode Nasa Tlx pada Operator Kargo di PT. Dharma Bandar Mandala (PT. Dbm)

Abstract

The titled of this research is Mental Workload Analysis using NASA-TLX Method for Cargo Carrier in PT Dharma Bandar Mandala (PT. DBM). PT Dharma Bandar Mandala is a company that engaged in the field of freight, the activities that undertaken is cargo shipment by airfreight. In conducting its activities cargo operator of PT DBM are accustomed to work under high pressure so that the operator mental workload increase. So it is necessary to analyze mental workload and the factors that influence it. So that PT DBM can determine the appropriate steps to improve the condition. The method used to measure mental workload is NASA-TLX. NASA-TLX measure mental workload that divided into 6 dimensional aspects of the working elements. NASA-TLX is divided into two stages, first ratio of each scale and event scoring. From the calculation using NASA-TLX, values that obtained for all operators are at a moderate level with the greatest mental workload indicators scales are PD (Physical Demand) and MD (Mental Demand
