Abstract

Eyestrain on the user computer is marked by the complaints eyes during or after working at the computer. This study examines the relationship eyestrain on the user's computer in the computer lab by a factor of individual characteristics (gender and refraction of the eye) and work environment factors (light intensity). The study was conducted on 143 students who use computers in three computer labs. Measurement of eyestrain performed by questionnaire to the respondent. The results showed that there have been eyestrain experienced by 123 respondent (86 %). Pain in the neck, back and shoulders (13.4 %) is a sign of eyestrain often occur. Test statistics using chi square showed relationship between eyestrain with refraction of the eye (p-value=0.023) and eyestrain with light intensity (p-value=0.009), while the gender are not related to eye fatigue (p value = 0.344).

Abstract

This study examines the relationship type of monitor with eyestrain computer users in the computer lab of the Faculty of Science and Technology UIN Sunan Kalijaga. The study involved 192 respondents who use computers in the computer lab. Measurement of eyestrain performed by questionnaire to the respondent. The results showed that there has been eyestrain experienced by 160 respondents (83.3 %) . Pain in the neck, back and shoulders (13.7 %) is a sign of eyestrain often occur. Using chi square statistical test showed relationship between the type of monitor to eyestrain computer users (p-value = 0.043) . CRT monitor has a refresh rate that is smaller than the LCD monitor. The flicker on a CRT display make the eyes become tired quickly.

Abstract

Reaction time became one of the discussion in the Work Design Analysis and Ergonomics. Reaction time is used to measure work performance of a worker. A person who reacts quickly when subject to stimulation, indicates that the person has a high performance. Thus the high or low performance of a person is measured on the basis of the quick or slow of a person in reacting to the stimulus. This research will discuss about how to design and build a reaction timer built microcontroller with input in the keypad which equipped with data storage device.
