Tempeh is a traditional Indonesian food rich in vegetable protein and plays an important role in supporting national food security. UD. XYZ, a micro-enterprise in Lhokseumawe City, is one of the main producers of tempeh in the region. However, in its production process, the company experiences various obstacles, such as irregular fermentation times, delays in the packaging process, and a decrease in product quality that affect production efficiency and consumer satisfaction. This study aims to identify and reduce wasteful activities in the tempeh production process using the Lean Manufacturing approach through the Value Stream Mapping (VSM) method. Based on the analysis results, of the total production time of 3,994.61 minutes, 94.77% are value-added activities, 2.27% are non-value-added (NVA) activities, and 1.08% are necessary but not directly value-added (NNVA) activities. Some activities such as the cooling process and arranging products on fermentation racks require considerable time and are categorized as wasteful. Furthermore, several stages, such as soaking and fermentation, also exceeded the tactical time limit of 215.38 minutes per ton. Therefore, restructuring work processes and organizing production spaces is a necessary strategy to improve efficiency and quality.
