Abstract

Research Aims: This study aims to analyse the influence of top management's commitment on competitive advantage through supply chain digitalisation, responsiveness, and resiliency. Design/Methodology/Approach: Data were collected using a five-point Likert-scale questionnaire distributed to manufacturing practitioners with a minimum supervisory position. A total of 203 valid questionnaires were analysed. Data processing was performed using SmartPLS version 4.0 to test measurement and structural models. Research Findings: The study results indicate that eight hypotheses are accepted and one is rejected. Top management commitment positively impacts supply chain digitalisation, responsiveness, and resilience. Furthermore, supply chain digitalisation and supply chain resilience both positively impact competitive advantage. However, supply chain responsiveness did not affect competitive advantage. Theoretical Contribution/Originality: This research makes a theoretical contribution to the study of digital technology adoption in supply chain management. Digital technology adoption enhances companies' competitive advantage. Managerial Implications in the South East Asian Context: In Southeast Asia, there is still low integration, limited digitalisation, and vulnerability to supply chain disruption. The results of this study provide insight into the role of top management in initiating the adoption of digital technology to strengthen resilience and supply chain responsiveness, thereby improving competitive advantage. Research Limitation and Implications: This study has limitations, particularly on the research sample, which is located in East Java, Indonesia. Hence, the study results may not be valid in other countries.

Abstract

This study examines the influence of Green Brand Knowledge and Green Attitude on Purchase Intention regarding environmentally friendly skincare products, with Green Perceived Value mediating this relationship. Employing a quantitative approach, data were collected from 118 student consumers in Surabaya and analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM). The results indicate that Green Attitude and Green Perceived Value have positive and significant effects on Purchase Intention. Green Attitude also significantly influences Green Perceived Value. Although Green Brand Knowledge significantly affects Green Perceived Value, it does not directly influence Purchase Intention. Mediation analysis reveals that Green Perceived Value significantly mediates the relationship between Green Brand Knowledge and Purchase Intention, but not the relationship between Green Attitude and Purchase Intention. These findings suggest that purchase intention toward eco-friendly skincare products is primarily driven by consumers’ attitudes and perceived value, rather than knowledge alone. This study contributes to green marketing literature by clarifying the psychological mechanisms linking cognitive and affective factors in high-involvement product categories within emerging markets.

Abstract

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.

Abstract

This study aims to examine the influence of E-WOM on purchase decisions through the mediating role of customer trust and perceived value. This study was performed among Indonesian marketplace users. This research uses a quantitative approach, with survey data collected from 202 Generation Z individuals. Data were collected using a five-point Likert-scale questionnaire distributed via social media platforms WhatsApp, Instagram, and Facebook. Data were analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) with SmartPLS 4.0. The results indicate that E-WOM affects customer trust, perceived value, and purchase decisions. Customer trust influences purchase decisions and partially mediates the effect of E-WOM on them. In contrast, perceived value does not affect purchase decisions and does not mediate the relation of E_WOM on purchase decision. These findings suggest that customer trust plays a more critical role than perceived value in driving purchase decisions for Generation Z consumers. The study contributes to the digital consumer behavior literature by reinforcing the applicability of the S–O–R framework and highlighting the dominant mediating role of trust. Practically, the results imply that marketplace platforms and sellers should prioritize strategies that enhance credible E-WOM and strengthen consumer trust rather than relying solely on value-based or price-driven approaches.

Abstract

This study aims to examine the influence of gamification experience on purchase intention, with perceived trust, perceived value, and customer engagement as mediating variables, among Shopee e-commerce users in East Java Province. This study uses a quantitative approach, with numerical scale data collected via an online questionnaire in Google Forms. The research population comprises individuals in East Java who have used Shopee and made transactions on it. The sampling technique used was nonprobability judgmental sampling, with the criteria that respondents were at least 17 years old and had made transactions in the last three months. A total of 200 respondents met the criteria and were analyzed in this study. All measurement items were graded using a five-point Likert scale, ranging from 1 (strongly disagree) to 5 (strongly agree). Data analysis was carried out using descriptive statistics and Structural Equation Modeling based on Partial Least Squares (PLS-SEM). The results show that gamification experience has a significant effect on perceived trust, perceived value, and customer engagement, with the strongest influence on customer engagement. However, the gamification experience does not have a significant direct effect on purchase intention. In addition, perceived value and customer engagement have a significant effect on purchase intention, whereas perceived trust does not. Mediation analysis showed that perceived value and customer engagement mediated the relationship between gamification experience and purchase intention, whereas perceived trust did not. These findings confirm that engagement-based mechanisms and value perceptions are more decisive in translating gamification experiences into purchase intent than trust alone, thereby expanding the theoretical understanding of gamification's effectiveness in the context of digital commerce.
