Abstract
In the process of dismantling tapioca flour, waste occurs due to activities that do not provide added value (Non-Value Added). The purpose of this study is to identify and analyze the types of waste and then propose improvements to eliminate activities that do not provide added value. By using the concept of lean supply chain and value stream mapping (VSM) it is expected to eliminate activities that do not provide added value and make the company more productive. Through the analysis of seven wastes and fishbone diagrams, it is known that the biggest causes of waste are waiting for the arrival of workers, waiting for pilot/tug boats, waiting for trucks to arrive, and working on sacks that have fallen and torn. Meanwhile, the recommendations given are to coordinate and evaluate the performance of workers, increase the number of pilot/tug boats and trucks, and supervise the unloading process to minimize mistakes made by workers. With the proposed improvement, the cycle time, which was originally 335.34 minutes decreased to 271.97 minutes, and for Process Cycle Efficiency (PCE) which was originally 68.30% increased to 84.22%.
