MICRO ERGONOMICS: THE INFLUENCE OF HUMAN CHARACTERISTICS TOWARDS MENTAL WORKLOAD AMONG ONLINE MOTORCYCLE OJEK DRIVERS

Abstract

The purpose of this study is to investigate how significant influence of online motorcycle ojek drivers’ characteristics towards mental workload based on three categories: under load, optimal and overload. Moreover, this study also analyzed using two perspectives: burdened and unburdened perspectives with NASA TLX as a measurement method. The research methodology used integrated fields research – non-parametric comparative. Determination of the sample used the Lemeshow method with a total of 70 samples. The test technique used Chi Square and intervention development. The findings of three categories achieved that there was a significant influence of Body Mass Index (BMI) on online motorcycle ojek drivers’ Mental with a score 0.070<0.1. Furthermore, there was a substantial effect of gender to online motorcycle ojek drivers’ frustration with score 0.062<0.1. However, the analysis using two categories with burdened and unburdened using NASA TLX demonstrated that there was no effect of drivers’ mental, physical, temporal, performance, frustration and effort towards mental workload.
