Companies strive to win the competition to maintain sustainability. This study aims to analyze the effect of supply chain integration on financial performance through green supply chain management and supply chain risk management in manufacturing companies in East Java. This study employs a quantitative approach, utilizing a causal research design, with 90 respondents from manufacturing companies that have implemented environmentally friendly practices. Data analysis was conducted using Partial Least Squares Structural Equation Modeling (SmartPLS 4.0) to examine the relationship between research variables. The results indicate that supply chain integration affects both green supply chain management and supply chain risk management, but it does not directly impact financial performance. Green supply chain management and supply chain risk management have been shown to have a positive effect on financial performance. Manufacturing companies with supply chain integration do not directly influence financial performance; instead, they do so through well-managed green supply chains and by mitigating supply chain risk. The results of the study emphasize the importance of synergy between supply chain integration, green supply chain, and supply chain risk management in building a sustainable and resilient supply chain. The theoretical contribution of this research is to broaden the understanding of the relationship between integration, sustainability, and risk in the context of the manufacturing industry in developing countries. The practical contribution of the research results provides manufacturing managers with guidance to strengthen internal and external coordination in implementing green management and risk management, thereby improving operational efficiency and financial performance.

This study aims to analyze the effects of digitalization of financial flows in the supply chain and supply chain integration on firm competitive advantage through supply chain resilience in manufacturing companies in East Java. This study uses a quantitative, survey-based approach. Data were collected through questionnaires from respondents working in medium- and large-scale manufacturing companies who met the criteria of having at least 3 years of work experience and understanding the company's supply chain activities. Data analysis was conducted using the Structural Equation Modeling-Partial Least Squares (SEM-PLS) method. The results show that digitalization of financial flows in the supply chain has a positive and significant effect on supply chain integration and resilience. However, digitalization of financial flows does not directly affect a firm's competitive advantage. Supply chain integration has been shown to affect supply chain resilience and a firm's competitive advantage. The research findings also show that supply chain resilience has a positive and significant effect on a firm's competitive advantage. These results confirm that digitalization of financial flows in the supply chain does not directly create competitiveness but rather serves as a supporting capability that strengthens supply chain integration and resilience. Thus, companies need to manage financial digitalization, supply chain integration, and supply chain resilience in an integrated manner to build a more sustainable competitive advantage.

Manufacturing companies are making a quick effort in anticipation of erratic business changes. Internal changes were made to adapt to the company's external conditions. Partnerships are needed to connect internal and external parties through supply chain collaboration, thereby improving supply chain performance and increasing competitiveness. Data collection from 99 manufacturing companies. The hypothesis was tested using partial least squares software. The data processing results indicate that supply chain collaboration positively influences product technology, product knowledge, new product development, and supply chain performance. The company's product technology has a positive impact on improving product knowledge, new product development and supply chain performance. The results of the hypothesis test also show that supply chain performance is influenced by product knowledge and new product development. The contribution of the theory of research results to enrich supply chain theory in producing product technology, product knowledge, and company competitiveness. A practical contribution is to provide guidance for company managers to carry out supply chain collaboration to improve performance and competitiveness.

Fuel supply shortages and price fluctuations pose significant challenges to the sustainability of fuel station business performance. These conditions require companies to strengthen vendor capabilities, integrate with supply chain partners, improve inventory management, and collaborate with them. This study aims to analyze the influence of vendor competency on vendor-managed inventory and supply chain collaboration, and the influence of vendor-managed inventory and supply chain collaboration on business performance, with supplier integration as a moderating variable. This study used a quantitative, survey-based approach. Data were collected via a Google Form questionnaire from 70 permanent fuel station employees. The sampling technique used was purposive sampling, while data analysis was conducted using Partial Least Squares-Structural Equation Modeling (PLS-SEM). The results show that vendor competency has a positive and significant effect on vendor-managed inventory but not on supply chain collaboration. Supplier integration has a positive and significant effect on vendor-managed inventory and supply chain collaboration. However, supplier integration moderates the relationships between vendor competency, vendor-managed inventory, and supply chain collaboration in a negative direction. In addition, vendor-managed inventory and supply chain collaboration have been shown to have a positive and significant effect on business performance. These findings suggest that improvements in fuel station business performance are more effectively achieved by strengthening inventory management systems, integrating information, and collaborating across the supply chain, rather than simply improving individual vendor competencies.
