Mental workload analysis on fruit truck suppliers using NASA-TLX method in giwangan market area

Abstract

Abstract Several times the truck driver received complaints from consumers (merchants) related to the inaccuracy in delivering the goods, and the quality of the goods declined. The driver stated that most of this happened because of the unfavorable market conditions so that it was not possible for drivers who arrived at the Giwangan market to carry out the loading and unloading process directly. That is because drivers are forced to wait up to 1-5 hours in the Giwangan market area to unload goods. These things are thought to add to the mental workload of truck drivers. The method used to measure mental workload using a questionnaire on the NASA-TLX method. The number of respondents sampled in this study were 20 (twenty) people, and all male. The respondents’ age is divided into two categories, namely early adulthood (18-40) and middle adulthood (40-60). The NASA-TLX calculation results stated that the workload of fruit truck drivers on the market during normal day conditions is classified as “High” with a score obtained of 70.26. The correlation test has resulted in the more age of the fruit truck driver, the lower the workload’s value.
