The Effort to Reduce a Muscle Fatigue Through Gymnastics Relaxation and Ergonomic Approach for Computer Users in Central Building State University of Medan

Fatigue due to long and continuous computer usage can lead to problems of
dominant fatigue associated with decreased performance and work motivation. Specific targets
in the first phase have been achieved in this research such as: (1) Identified complaints on
workers using computers, using the Bourdon Wiersma test kit. (2) Finding the right relaxation
& work posture draft for a solution to reduce muscle fatigue in computer-based workers. The
type of research used in this study is research and development method which aims to produce
the products or refine existing products. The final product is a prototype of back-holder,
monitoring filter and arranging a relaxation exercise as well as the manual book how to do this
while in front of the computer to lower the fatigue level for computer users in Unimed’s
Administration Center. In the first phase, observations and interviews have been conducted and
identified the level of fatigue on the employees of computer users at Uniemd’s Administration
Center using Bourdon Wiersma test and has obtained the following results: (1) The average
velocity time of respondents in BAUK, BAAK and BAPSI after working with the value of
interpretation of the speed obtained value of 8.4, WS 13 was in a good enough category, (2)
The average of accuracy of respondents in BAUK, in BAAK and in BAPSI after working with
interpretation value accuracy obtained Value of 5.5, WS 8 was in doubt-category. This result
shows that computer users experienced a significant tiredness at the Unimed Administration
Center, (3) the consistency of the average of the result in measuring tiredness level on
computer users in Unimed’s Administration Center after working with values in consistency of
interpretation obtained Value of 5.5 with WS 8 was put in a doubt-category, which means
computer user in The Unimed Administration Center suffered an extreme fatigue. In phase II,
based on the results of the first phase in this research, the researcher offers solutions such as
the prototype of Back-Holder, monitoring filter, and design a proper relaxation exercise to
reduce the fatigue level. Furthermore, in in order to maximize the exercise itself, a manual
book will be given to employees whom regularly work in front of computers at Unimed’s
Administration Center
