Integrating Green Overall Equipment Effectiveness (G-OEE) and Reduce Strategies: A Transformation Toward Sustainable Cigarette Manufacturing
The cigarette manufacturing sector currently faces a dual mandate: maximizing production efficicency while drastically reducing its environmental footprint. Traditional Overall Equipment Effectiveness (OEE) metrics often fail to capture ecological dimension, creating a significant measurement gap in sustainable performance. This study addresses this limitation by developing and validating an Integrated Green Overall Equipment Effectiveness (G-OEE) model. By embedding the "Reduce" principle of the Circular Economy (CE) into the classic OEE framework, this research provides a nuanced evaluation of manufacturing operations in East Java. Employing a mixed-methods approach, the study analyzed quantitative data from January 2025 to March 2026, encompassing Availability, Performance, Quality, and Reject rates. The proposed G-OEE model expands the traditional APQ pillars by integrating three critical Green Performance Factors: energy efficiency (GPF1), material utilization (GPF2), and a waste reduction index (GPF3). Findings reveal a striking disparity: while conventional OEE averaged 82.74%, the G-OEE score dropped to 62.20%. This gap effectively exposes hidden environmental inefficiencies that standard metrics typically overlook. The regression validation (R² = 0.89, RMSE = 3.2%) confirms the model’s high predictive validity, establishing G-OEE as a practical decision support tool for production managers. Ultimately, the G-OEE framework enables manufacturers to align Lean efficiency with Circular Economy responsibilities through a single, simultaneous monitoring tool.

Relationship Between Organisational Culture and Customer Focus on Operational Performance: An Agile Manufacturing Approach
This paper aims to empirically test the relationships between organizational culture and customer focus, and their impact on operational performance in shipbuilding companies in the context of agile manufacturing. This research used a quantitative PLS-SEM method, with 155 respondents from 27 shipbuilding companies in Indonesia, collected via an online survey using random sampling. The results showed that organizational culture does not directly influence operational performance. Meanwhile, customer focus significantly affects operational performance, and it also mediates the relationship between organizational culture and operational performance. This study fills a gap in manufacturing strategy by adopting an agile manufacturing approach to improve the operational performance of shipbuilding companies, which is measured by indicators of construction time, quality, construction cost, and sales revenue. Besides, this study contributes empirical evidence on the relationship between organizational culture and customer focus, and their impact on operational performance in shipbuilding companies.

Optimization of Distribution Routes for Srikandi MSMES in Samarinda Using VRP Method: A Comparative Study of CWS and CFRS
This research aims to optimize the distribution route of snack products for UMKM Srikandi Samarinda using the Vehicle Routing Problem (VRP) approach. The main issues are high travel distances, fuel costs, and delivery times due to the absence of route optimization. Two VRP solution methods are compared: Clarke and Wright Savings (CWS) and Cluster First Route Second (CFRS). The CWS method reduces travel distance by combining routes based on the highest distance savings between customer points, maximizing vehicle capacity. The CFRS method groups customer points into clusters using the Sweep algorithm based on proximity to the depot and determines the visit sequence within each cluster using the Nearest Neighbor method. Results show CFRS achieves better distribution efficiency. On the first route, CFRS traveled 94.1 km using 7 liters of fuel (Rp88,550), while CWS traveled 113.7 km using 9 liters (Rp113,850). On the second route, both methods covered about 75 km with similar fuel costs (Rp75,900), but CFRS was more consistent in savings, with the highest efficiency at 63.28%. With a total fuel cost saving of Rp140,939 compared to the initial condition, CFRS is recommended as the optimal solution, capable of reducing distance, operational costs, and improving delivery effectiveness.
