In a working system, standard time is a parameter to measure or analyze the performance of workers, also used to improve flow process efficiency and determination of production targets. Standard time is obtained by work measurement. Work measurement is the evaluation of the time required to complete a job using the stopwatch and other methods. It enables the organization to promote productivity and measure direct time study. However, there are several challenges associated with its implementation such as the continuous analysis of workers from start to finish by an observer. This leads to the inability of the observer to carry out other activities, workers tend to work inadequately under supervision, and limited timeframe. These challenges led to the development of a technology that measures work takes more measurements and produces accurate and real-time cycles without the presence of observers. Therefore, the purpose of this research is to develop a technology with the ability to automatically measure work directly using the vision sensor technology. The designed equipment measures the movement of workers based on color, which is converted into work time, and further processed into standard time using an application program. The results of this study are vision sensor technology, which is an integration of hardware (Pixy CMUcam5 and Arduino Uno Rev 3 components with AT Mega 328P) and application programs (Visual Studio 2015 programming). Furthermore, based on usability testing, the results have shown that parameters were able to function accurately and in real-time, and based on the mean of standard time, it is seen that the difference in measurement of time using technology and stopwatch is only 7.8%.
