menyeluruhPT. X is an industrial company engaged in the manufacturing of motor vehicles with four or more wheels, including the assembly of Light Duty Trucks (LDT) and Medium Duty Trucks (MDT), component assembly, and spare parts production. In its operations, PT. X has the potential to impact the environment due to the generation of hazardous waste. Environmental issues related to the negative impacts caused by industrial activities at PT. X have influenced the company's management to implement policies aimed at improving performance. This study aims to comprehensively understand the material flow of hazardous waste at PT. X, covering waste generation processes, management practices, and challenges within the existing system. The approach used in this research is the Material Flow Analysis (MFA) concept, utilizing the STAN2WEB software as a tool for structured and in-depth analysis of hazardous waste material flow. The system boundary in this study focuses on the production processes and sub-processes of Medium Duty Trucks (MDT) and Light Duty Trucks (LDT), consisting of two main processes: machining and assembly at PT. X. Based on the material flow analysis, it can be concluded that the material sub-processes of Cylinder Block, Camshaft, and Cylinder Head are the largest contributors to hazardous waste e generation in the form of kiriko (metal chips) in PT. X’s automotive production process. Kiriko or metal chips are generated from the machining process, which involves material removal to shape components according to design specifications. This process removes unnecessary parts of the material, producing waste in the form of metal chips or metal shavings. These findings highlight the importance of optimizing hazardous waste management to support the company’s sustainability and operational efficiency. Efforts such as recycling and reusing kiriko waste should be considered to minimize environmental impact and improve the company's overall environmental performance
