Lean manufacturing has been widely applied in companies and proven to improve operational performance. Lean is mainly applied to the automotive industry. However, now it has been widely applied in other sectors by considering the characteristics of the application field, including the agro-food sector. The purpose of this study is to evaluate the production process in SMEs, which is still done conventionally. The research begins by using value stream mapping to identify inefficiencies. The results of current-value stream mapping state that the efficiency of the production process is 71.34%. The Failure Mode Effect Analysis results state that the critical waste that occurs is overprocessing, waiting, and transportation time. Proposed improvements are made by applying the 5S concept, layout design of the production area, and mechanization of the boiling and filtering processes. Efficiency in future value stream mapping is estimated to increase by around 20%.
