Summary

This study investigates the mental workload experienced by two-wheeled online motorcycle taxi (ojek online) drivers in Banjarmasin, Indonesia. The research was motivated by the rapid expansion of digital transportation services, which, while offering flexibility, impose significant cognitive and physical demands on drivers. Factors such as heavy traffic, the need for constant focus, performance ratings, and income uncertainty contribute to potential stress and mental fatigue. The study aims to quantify this workload to identify specific stressors and propose ergonomic and operational improvements. The researchers employed the National Aeronautics and Space Administration Task Load Index (NASA-TLX) method, a subjective multidimensional tool for assessing mental workload. Data were collected through direct observation and questionnaires administered to 67 male drivers in Banjarmasin. The respondents ranged in age from 19 to 56 years, with the majority working more than eight hours per day. The NASA-TLX assessment measured six dimensions: mental demand, physical demand, temporal demand, performance, effort, and frustration. The data were processed by calculating weighted scores for each dimension to determine the overall mental workload level and identify the most dominant contributing factors. The results indicate that the average mental workload for these drivers is high, with a mean NASA-TLX score of 52%. Specifically, 58.2% of respondents fell into the "high" workload category, while 41.8% were in the "moderately high" category. The primary contributors to this mental load were physical demand (19.96%) and effort (19.27%), followed by performance pressure (18.06%), temporal demand (17.74%), mental demand (14.36%), and frustration (10.60%). The high physical demand reflects the strenuous nature of riding in challenging urban environments, while the high effort score indicates the continuous exertion required to meet service targets. Notably, frustration levels were relatively low, suggesting drivers may perceive their workload as manageable despite its intensity. The study concludes that ojek online drivers in Banjarmasin face significant mental and physical challenges that require intervention. To mitigate these effects, the authors recommend that platform companies improve application quality, particularly GPS accuracy, to reduce navigation errors and stress. For drivers, the study emphasizes the importance of proper vehicle ergonomics, including maintaining relaxed shoulder and back postures, and managing work hours to prevent fatigue. These findings highlight the need for better support systems for informal transport workers to ensure their health and safety in high-demand digital labor markets.
