The results of this study indicate that the average data obtained shows that the performance of the new system is much higher than the old system. The average performance of the old system = 48%, and the new system is 78%. Working speed of the old system = 57% and 75% of the new system. The comfort of the old system = 50% and the new system is 85%. Based on these data it can be seen that the new work system can increase the average system performance by 30%, work speed by 18%, work comfort by 35%, and work productivity by 25%.
