The Influence of Employee Performance, Supply Chain Management and Service Quality on Operational Performance Power as a Service Regional Sumbagsel PT. XYZ

This research aims to analyze the influence of Employee Performance, Supply Chain Management, and Service Quality on Operational Performance in the Power as a Service (PaaS) business at PT. XYZ Regional Sumbagsel. The resarch utilized a quantitative design involving survey data from 568 subjects including Site Engineers and Site Engineer Coordinators. Data analysis was performed utilizing the Partial Least Squares-Structural Equation Modeling (PLS-SEM) technique via SmartPLS 4. The empirical findings indicate that Employee Performance, Supply Chain Management, and Service Quality have a positive and significant effect on Operational Performance, both partially and simultaneously. The Service Quality variable has the most dominant influence on improving operational performance. The research model also showed good predictive ability with an R-Square value of 0.543 and Q-Square of 0.532. These findings indicate that the success of operational performance in the PaaS business is greatly influenced by the integration of human resource quality, supply chain effectiveness, and consistency of service quality in supporting the achievement of Service Level Agreements (SLAs). This research contributes to the development of operational management literature, especially on the telecommunications infrastructure industry which demands a high level of service reliability and minimal downtime.

Optimizing Reverse Logistics in Manufacturing Production Processes

This study investigates the optimization of reverse logistics in manufacturing enterprises, emphasizing its role as an essential component of modern supply chain management and a strategic instrument for sustainable development. The paper first reviews and systematizes the theoretical foundations of reverse logistics, clarifying its concepts, characteristics, and scope of application, as well as its linkages with supply chain management and the circular economy. On this basis, an analytical framework is developed to evaluate the level of reverse logistics implementation in manufacturing firms in Vietnam, with a focus on product return management, reverse material flow handling, internal coordination mechanisms, and the integration of environmental objectives into production and business strategies.

The analysis of empirical evidence highlights several key challenges in the adoption of reverse logistics, including limitations in managerial capabilities, infrastructure, financial and technological resources, and insufficient awareness of the long-term economic and environmental benefits. In response, the study proposes a set of comprehensive and feasible solutions aimed at improving internal governance, enhancing coordination across supply chain stages, and promoting the adoption of management models consistent with circular economy principles. These measures are expected to improve operational efficiency, reduce environmental impacts, and strengthen the competitive position of manufacturing enterprises in the context of economic integration and increasing sustainability requirements.
