Online published on 1 November, 2018. Abstract Fatigue is a problem experienced by every worker, especially computer operators that until now cannot be overcome. Various methods used in analyzing the occurrence of muscle fatigue under the computer operator, such as handgrip and lactic acid blood plasma levels. This study aimed to find a method of measuring muscle fatigue in computer operators that can be applied in the field or workplace with the principle of simple, fast and cheap without ignoring the level of accuracy. The results showed that there was a correlation between the measurement of handgrip method with a lactic acid concentration of blood plasma to muscle fatigue, where p = 0.000 <0.05 with rs = 0.667. Furthermore, it can be concluded that measurement of handgrip method and lactic acid blood plasma level as a fast, simple and cheap method can be used as a parameter to determine the fatigue of the forearm muscle of computer operator after working in the computer.
