Waste management problems in Kudus City show high complexity, marked by an increase in the volume of daily waste generation that is not balanced by an adequate handling system. This study aims to optimize the waste management system in an integrated manner with an industrial engineering approach, especially through the application of the Lean Waste Management concept, redesigning facilities and logistics, and strengthening community participation based on Human-Centered Design (HCD). A qualitative method with a case study approach was used, with data triangulation techniques in the form of in-depth interviews, direct observation, and document analysis. The results of the study showed that 75% of households did not sort their waste, only 2 out of 6 TPSTs were active, and the TPA capacity had exceeded its limit since 2022. The efficiency of the transportation system is also low due to suboptimal routes and frequencies. This study offers solutions based on technology integration, facility redesign, logistics optimization, and community empowerment. With a systemic approach based on industrial engineering, an efficient and sustainable waste management model can be applied, not only in Kudus, but also in other areas with similar challenges.

Lean Management is a method that emphasizes reducing waste and increasing added value in healthcare service processes. Through a systematic literature review, this study identifies various aspects of Lean implementation in hospitals, such as reducing patient waiting times, optimizing resource utilization, and improving patient satisfaction. The findings reveal that Lean Management implementation not only supports operational efficiency but also enhances service quality and patient experience. The success of this method heavily depends on management support, active staff involvement, and adequate training. This study also highlights challenges such as resistance to change and budget constraints. These findings have significant implications for hospital managers and policymakers in formulating strategies to improve healthcare service effectiveness. Recommendations for future research include empirical studies examining Lean implementation in various hospital contexts, particularly in developing countries. This study aims to explore and analyze strategies for improving hospital operational efficiency through the Lean Management approach.
