Gold is a precious metal commodity used in many industries. Developing research institutions assess gold as a safe haven for investors during severe market pressure. In Indonesia, there are 15 gold producers, with one of the largest being PT Antam, Tbk. ("ANTAM"). The Precious Metal Processing and Refining Business Unit is part of ANTAM's operations and is responsible for gold processing and refining facilities. To respond to the growing demand for precious metal products, the Precious Metal Factory is expected to optimize its production capacity and product quality. Currently, the lack of recording and standardization, as well as the absence of digitization in the production process, results in significant loss and high cycle time. The aim of this study is to conduct a process reengineering analysis to reduce cycle time and increase production in the production of Antam's Precious Metal. This involves identifying waste in the production process using Value Stream Mapping (VSM) and optimizing the layout and facilities to meet the production capacity of Antam's Precious Metal
