EVALUATION OF THE CABIN TEMPERATURE EFFECT ON DRIVER SLEEPINESS LEVEL USING ELECTROENCEPHALOGRAPHY (EEG) AND KAROLINSKA SLEEPINESS SCALE (KSS)

There are about 1.3 million people who die from traffic accidents every year worldwide. In Indonesia itself, the number of traffic accidents is fairly high and tends to increase every year according to data from Badan Pusat Statistik (BPS). The human factor is often determined as the main factor causing accidents. In humans, fatigue is considered the main cause of transportation accidents with drowsiness being one of the indicators. One of the actions that can be taken to prevent the driver from increasing the level of sleepiness is to adjust the temperature inside the vehicle. The temperature of the working environment contributes greatly to the level of fatigue. Therefore, this study was conducted to determine the optimal temperature range to reduce the level of sleepiness of drivers in order to reduce the rate of traffic accidents in Indonesia. The method used in this research is Electroencephalography (EEG) for objective measurement and Karolinska Sleepiness Scale (KSS) for subjective measurement. The results of this study are expected to be used as an alternative to prevent and reduce the rate of traffic accidents.
