| Summary: | Fatigue is an important factor that contributes to the decline in someone's performance. This study aims to identify how much influence the duration of driving a combat vehicle has on the decline in cognitive function. A total of 8 TNI-AD soldiers were asked to drive a combat vehicle within 2 hours. Objective measurements using the Psychomotor Vigilance Task (PVT) were tested before and after the driving simulation, and subjective measurements using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. The results of non-parametric statistical tests using the Friedman Two Way Anova test showed that the four parameters in PVT consisting of PVT-m (mean), PVT-f (fastest), PVT-s (slowest), and PVT-l (lapse) had significant differences between the duration of driving for 1 hour and 2 hours on the cognitive function of soldiers. In this study, several conclusions were obtained including the first, driving a combat vehicle within 2 hours resulted in a decrease in cognitive function by 7.8% to 69.4%. Second, it is recommended for Pusdikkav Bandung to start implementing the allocation for tank drivers every 2 hours, the main driver can be temporarily replaced by a backup driver. In addition, it can be proposed for the party that produces the AMX-13 Tank and FV101 Scorpion Tank to add an air conditioner (AC) instrument, ear plug, and shock breaker. Another alternative is the commander and gunner positions, it is recommended that they be trained to be able to drive the tank or consider increasing the capacity in the tank to 4 people (driver, commander, gunner, and backup driver). Finally, when the Spearman Rank Correlation Test was carried out between the duration of driving a combat vehicle for 2 hours and the results of the PSQI questionnaire, it showed a low correlation. This can happen because PVT is very sensitive to protocols, equipment, and environment.
