This study aims to improve productivity in the skimming furnace process of a Large Nickle Company by applying the Sustainable Value Stream Mapping (Sus-VSM) method. This company focuses on the exploration and processing of nickel ore in Indonesia with an average production of 75,000 tonnes per year. By considering environmental, social, and economic aspects, the research aims to identify and eliminate waste that becomes a bottleneck in the production of nickel matte. The research used the American Productivity Center (APC) method to measure current productivity, while the Line Balance Ratio (LBR) assessed production imbalance. The cause of the problem was analyzed using fishbone analysis, and waste was corrected using the lean concept. The results show that the application of Sus-VSM can increase the productivity and efficiency of the furnace skimming process by reducing the duration of NVA (Non-Value Added) in the close to open skimming process by 21.27 min, determining the standard time to perform close to open skimming work for 164 min, improving operator working conditions by implementing the use of ear protection devices in the form of helmet mounted earmuffs, and designing modifications to the automatic rosebud tool equipped with hydraulic. Thus, the Sus-VSM method can be a sustainable solution to improve productivity and production balance in the nickel mining industry. The proposed improvements depicted in the future continuous value stream mapping can increase the time efficiency of the close to open skimming process by 5%.
