PT Paragon Technology and Innovation (PTI) is one of the largest cosmetic companies in Indonesia. The existence of a warehouse at PT PTI is important to meet customer demands. At PT PTI PM Warehouse, warehousing activities started from loading and unloading, quality checking, transit, stocking, picking, and dispatch. Based on the observations, there were pallets scattered along the rack aisle as a result of waste. Therefore, it is necessary to evaluate the activities at PT PTI PM Warehouse to identify and eliminate waste. The lean manufacturing concept is used to identify wastes in PT PTI PM Warehouse. This concept consists of three main parts, namely making the map of the current state, analyzing the current state map, and designing the future state. In the current state map phase, mapping is carried out using value stream mapping (VSM) to depict warehouse activity in general and process activity mapping (PAM) to obtain a more detailed activity mapping. After mapping the warehouse activities, the identification of waste and root cause is carried out using a tree diagram. After that, an improvement is designed to solve the selected root causes. Finally, the future state map design and improvement analysis can be done. Based on the existing VSM, the non-value added activities are 34.98 minutes or 63.18% of the average total dock-to-stock time. From the results of identifying waste, found 4 main wastes, namely waiting time, excessive processing, defects (application errors), and inventory. The root cause chosen to be solved was 'there are no tools used to visualize the condition of pallets and shelves in real-time'. To solve this root cause, a prototype of visualization of the condition of pallets and shelves in real-time was designed using the Google Sheets application. With this improvement, the waste found in the PM PTI Warehouse can be reduced so that an estimated reduction in activity duration of 19.44 minutes or 55.80% of non-value- added activities can be achieved.
