Relation between feelings of fatigue, reaction time and work productivity.

Taking into consideration the limited amount of research that has been done focussing on fatigue among workers in Indonesia, the writer has taken it upon herself to investigate the indicators of chronic fatigue of the concrete block and sewer pipe cast workers of a place located in Sleman District of Yogyakarta. The purpose of this study was to prepare an instrument to evaluate the feelings of fatique; to know the relationship between feelings of fatigue measure and reaction time measure on work productivity, to know the relationship between feelings of fatigue measure and reaction time measure. 1) KAUPK2 were prepared to evaluate the feelings of fatigue in chronically fatigued Indonesian workers. 2) There is a significant correlation between feelings of fatigue measure and work productivity, and between reaction time measure and work productivity as well. 3) There is no significant correlation between feelings of fatigue measure and reaction time measure. 4) There is a significant difference between both work productivities. The mean decrease in work productivity relative to reaction time is smaller than relative to the feeling of fatigue. 5) This investigation also clarified other kinds of relationships such as that between feelings of fatigue and work productivity between workers less than 25 years old and those more than that age. Based on the regression analysis, there was no significant correlation between reaction time and work productivity at the age of less than 25 years, but there was a significant correlation between feelings of fatigue and productivity. For workers 25 years old or older, the result is the reverse.(ABSTRACT TRUNCATED AT 250 WORDS)
