STUDI TENTANG GETARAN DALAM HUMAN DISPLAY INTERFACE DAN PENGARUHNYA TERHADAP KELUHAN SUBYEKTIF OPERATOR DI PT ? EJ ? DENPASAR SELATAN.

Abstract

The aim of this research is to study the effect of vibration in human display interface on operator subjective complaint at PT ?EJ? in South Denpasar. Methods used in this research are observations and measurements on the operators and environmental conditions. Variables involved in this research are namely: the operators? age, weight and height, dry and wet bulb temperatures, humidity and noise level. The results showed that the average age, weight and height of the operators were 26,71 (? 7,13) years, 58 ,4 ( ? 1,1) kg, and 164, 14 (?3,43) cms respectively.

The operator complaints were: severe low backpain, pressure on breathing, feeling thirsty, tremor, feeling unhealthy and feeling stiff at the eyelid.
