Abstract

The quail farming industry in Indonesia has recently experienced significant growth, which has led to an increase in demand for quail eggs. This shows substantial challenges in quail egg farming, namely low operational efficiency and high levels of waste in the production process. This study aims to improve operational efficiency by reducing waste in a quail egg farming production at CV. Vigaza uses lean manufacturing and the theory of constraints. Lean tools such as value stream mapping, waste assessment model, and value stream analysis tools are applied to identify the dominant wastes. The theory of constraints is used to determine the root cause using the current reality tree. The process activity value-added ratio has improved from 60.73% to 68.91%, lead time has decreased from 12.1 to 10.99 days, and the defect rate has reduced from 0.68% to below 0.5%. Overproduction is recommended to align production with the market demand rather than the production cycle. Integrating the lean method and the constraint theory effectively reduced waste in a small-scale agricultural production, a quail egg farm. These findings suggest a potential for adopting lean techniques in the agricultural sector in Indonesia. Keywords: Lean Manufacturing, Value Stream Mapping, Waste Assessment Model, Value Stream Analysis Tools, Theory of Constraints

Abstract

This research is conduct with the object to observe whether that lean, agile, resilience, green, and sustainable can be applied into a laundry supply of supply chain management. Literature review are reviewed to build a foundation regarding SCM to achieve the objectives. Model of lean, agile, resilience, green, and sustainable are built on the theoretical review of literature. The novelty of this research is to classify scheme of a laundry supply chain paradigm in SCM was developed. The result indicates that lean, agile, resilience, green, and sustainable have a important role to achieve successful performance, and customer satisfaction.
