The Application of Lean Manufacturing in Improving Production Process Efficiency in Manufacturing Industry
Keywords:
Manufaktur Ramping, Efisiensi Operasional, Peningkatan Produksi, Pengurangan Limbah, Perbaikan BerkelanjutanAbstract
This research addresses the critical need to improve operational efficiency in the manufacturing sector, particularly in Indonesia, where inefficiencies have led to a 2.3% decline in productivity by 2023. The purpose of this study is to analyze the implementation of lean manufacturing practices and its impact on production efficiency. Using a mixed-methods approach, data was collected from 110 medium and large-scale manufacturing companies in the Medan area through surveys and interviews. The findings show that lean manufacturing can increase production efficiency by 33.9% and significantly reduce lead time. Key lean tools such as 5S and Value Stream Mapping proved effective in minimizing waste and improving overall operational performance. This research concludes that a comprehensive framework for lean implementation is essential to achieve continuous improvement in manufacturing efficiency. Practical recommendations are provided for industry stakeholders to systematically adopt lean principles, encouraging a culture of continuous improvement.
