Abstract

Today's manufacturing companies face fierce competition. The ability of each company to meet customer needs and demand for quality and competitive products needs to be continuously improved. CV Putra Tanjung is one of the businesses that produces fish sponge cake in Padang City. To meet consumer demand, this company needs to increase productivity through effective and efficient production activities. This improvement can be achieved by reducing waste and increasing product value. This research aims to minimize the waste that occurs in the fish sponge cake production process at CV Putra Tanjung. Existing waste can be reduced by applying the concept of lean manufacturing. Waste identification using Waste Relationship Matrix (WRM) and Waste Assessment Questionnaire (WAQ) shows that the waste with the highest percentage is motion waste at 36.50%, followed by waste defect at 24.19%, and process waste at 17.60%. Furthermore, a tool was selected to analyze the flow on the production floor using Process Activity Mapping (PAM). The PAM results showed that the value-added activity was 37%, necessary non-value-added activity was 50%, and non-value-added activity was 13%. The causes of waste were identified using a fishbone diagram. Based on the findings, the recommendations for improvement include purchasing a planetary mixer with a whisk attachment, procuring ovens, flour measuring devices, gloves, cooling racks, and standardizing work systems. These improvements are expected to increase the Process Cycle Efficiency (PCE) value by 31.20%.
