Currently, the stopwatch method is widely used for measuring work time in production processes; however, it still has limitations in terms of accuracy, continuity, and labor requirements, often leading to errors and difficulties in retrospective verification. This research aims to design and develop a video-based work time analysis system for industrial production lines using web technologies combined with statistical data analysis, in order to enhance accuracy and overcome the limitations of traditional methods. The developed system is a web-based application that supports video uploads from workstations and calculates standard time along with statistical measures such as mean, median, standard deviation, and coefficient of variation. Experimental results from a simulated production line with 11 workstations showed that the system reduced manual time recording from over 110 instances to a single video upload per station. Moreover, it achieved a coefficient of variation (CV) as low as 0.74%, reflecting higher accuracy compared to the traditional stopwatch method.Therefore, the proposed system can be effectively applied to calculate standard time and support systematic analysis of production processes, ensuring practical and reliable use in industrial environments.
