The Application of Lean Six Sigma to Minimize Waste at the Biscuit Factory with the PDCA Method

In today's increasingly competitive industrial world, manufacturing companies are required to maintain the consistency of the production process. Factors that are inefficient and effective in the production process need to be anticipated so that companies do not require large costs in manufacturing products. To create the quality of the production process in accordance with established standards, companies need to implement a good quality control system.

The Challenge of Waste in the Biscuit Production Process

PT. Asia Sakti Wahid Foods, for example, faces challenges in operational efficiency due to waste that occurs in the biscuit production process. Product defects fluctuating degrees between 20.27% to 34.78%, far above the company's target below 10%. This high level of waste not only affects the company's productivity but also leads to significant financial losses. To overcome this problem, researchers applied Lean Six Sigma with the PDCA method to improve the quality of the production process.

Lean Six Sigma and PDCA Method: A Solution to Improve Efficiency

Lean Six Sigma is a methodology that combines the principles of Lean Manufacturing and Six Sigma to identify and eliminate waste (waste) in the production process. The PDCA method (Plan, DO, Check, ACT) is a structured cycle that helps in implementing changes and gradual improvements. By combining these two methodologies, companies can achieve significant improvements in efficiency and quality.

The Application of Lean Six Sigma with the PDCA Method at PT. Asia Sakti Wahid Foods

In the application of Lean Six Sigma with the PDCA method at PT. Asia Sakti Wahid Foods, researchers took a series of steps:
