Measuring the mental workload and identifying stress factors among public transportation drivers in Cikande, Indonesia

Public transportation is vital in providing access to important services and job opportunities. Road conditions such as congestion, deposit targets, competition between drivers, noise, and vehicle speed can cause mental stress in drivers. This study aimed to measure the mental burden of public transportation drivers in the Cikande area of Indonesia. The study involved 30 drivers who were selected using stratified random sampling. The mental load was measured using NASA-TLX, and the results showed that the mental workload of red public transportation drivers was high and very high, with mental demand being the highest dimension. The mental workload of red and white public transportation drivers was high and rather high, with the highest dimension being frustration level. The study found that internal and external factors influenced the mental workload of public transportation drivers. External factors include the environment, traffic, customer service, deposit targets, and old vehicle conditions. Internal factors include age, emotional exhaustion, and driver saturation level. This study provides insight into the mental burden experienced by public transportation drivers in the Cikande area and the factors that contribute to mental stress.
