Abstract

n the era of globalization and increasingly fierce competition, companies face complex challenges in managing supply chains that are both efficient and resilient to unexpected disruptions. Lean management approaches that focus on waste elimination can create vulnerabilities, while resilience engineering offers system robustness but potentially reduces efficiency. Purpose: This research aims to analyze the implementation of integrated lean management and resilience engineering approaches to improve supply chain performance holistically. Methods: The research employed a mixed methods approach with a before-after comparison study design conducted over 12 months in a manufacturing company. The research sample involved 16 respondents from various organizational hierarchy levels consisting of directors, managers, supervisors, and operational staff from five supply chain divisions (sales, procurement, production, warehouse, logistics). Results: The integrated implementation showed significant improvements across all divisions. The sales division experienced 39.7% sales growth, the production division achieved 117% productivity improvement with 54% lead time reduction, the warehouse division increased capacity by up to 1,400%, while the logistics division successfully minimized customer complaints and optimized operational costs. Overall, organizational performance improved from "Needs Improvement" category (195.12 points/39%) to "Adequate" category (343.56 points/69%). Conclusion: The integration of lean management and resilience engineering proved effective in improving supply chain performance through simultaneous optimization of operational efficiency and system resilience strengthening, creating a supply chain that is not only lean but also resilient.

Abstract

The increasing volume of waste in urban areas such as Yogyakarta is not supported by adequate public awareness or effective waste management systems. This study aims to design and evaluate the performance of an IoT-based portable waste incinerator as an efficient and feasible solution for household and community use. The prototype was developed using an iterative design approach with recycled materials and low-cost IoT components. Test results show that the device maintains a stable combustion temperature of 600–800 °C and achieves an average waste volume reduction of 85%. SO₂ emission levels remain below 120 ppm, meeting environmental safety standards. The IoT monitoring system, using an ESP8266 module and DHT22 sensor, enables real-time tracking of temperature and ash accumulation and provides automatic alerts for maintenance. Financial analysis indicates that production costs can be reduced by approximately 40%, resulting in an estimated unit price below IDR 4,000,000. Market validation across five locations in Yogyakarta shows an 85% interest rate and a satisfaction score of 4.2/5. Overall, the IoT-based portable waste incinerator demonstrates technical reliability, environmental efficiency, and market viability.
