PT XYZ is a company that manufactures various types of flexible packaging. Its production process involves several steps, one of which is dry lamination. During this process, the company faces issues due to the significant amount of time spent on non-value-added activities—specifically, 54.41% of the total process time of 4,080 seconds. This situation indicates the presence of waste, rendering the production process inefficient. This study aims to identify the types of waste present, analyze their root causes, and formulate improvement strategies using lean manufacturing and Kaizen methodologies. Value stream mapping was employed to identify specific activities, while fishbone diagrams and the 5W+1H method were used to determine the causes of the waste. The findings indicate that the primary types of waste include unnecessary motion, material handling, rework, errors, and waiting times—stemming from factors related to personnel, equipment, processes, materials, measurement methods, and the work environment.
