Abstract

Digital Literacy is essential in the post-pandemic era. Teachers use Digital Literacy to provide learning materials, conduct the teaching process, and conduct evaluations online. However, Digital Literacy requires adequate information technology infrastructure to produce classroom management and learning effectiveness on an ongoing basis. The study used questionnaires to obtain data on Christian-based schools in Surabaya. The questionnaires were distributed to as many as 363 through a Google form, and 132 were filled out again. Data processing used partial least square. The results showed that digital literacy has an impact on classroom management. Classroom management influences learning effectiveness. Digital literacy affects learning effectiveness through classroom management. Digital Literacy has not influenced classroom management and learning effectiveness with information technology infrastructure as a moderating variable. This research provides a practical contribution for education managers to understand the adjustment of IT infrastructure to make digital literacy the basis for managing class management. In addition, teaching staff must be educated to keep abreast of technological developments to support the teaching process and improve class management. The study enriches the theory of the use of technology in education and interactional education in the classroom.

Abstract

Information technology is essential for companies to make informed decisions that support internal business processes and external collaboration, thereby improving overall company performance. The research collected data from 105 manufacturing companies in East Java. The research sample was determined using judgmental sampling with respondents who were at least staff level and had become permanent company employees. Data analysis was used with SEM-PLS. Implementing information technology in manufacturing companies impacted internal and external supply chain integration. Internal supply chain integration, combined with internal data integration, is running smoothly and in real-time, which positively impacts cross-functional integration and does not directly affect company performance. External supply chain integration, in collaboration with external partners, is progressing well. The company is actively involved in developing these partnerships, which can lead to improved company performance, increased flexibility in meeting customer demands, and reduced production costs. Practical contributions to research provide insight for industry practitioners, enabling the internal cross-functional team to operate in an integrated manner and necessitating collaboration with external parties. Purchasing and marketing managers can play an active role in enhancing the involvement of external partners in improving company performance, making a theoretical contribution to enriching the development of information technology systems, and sustainable supply chains.

Abstract

The company's management always strives to enhance competitiveness by making business processes efficient and effective, while also paying attention to environmental protection. This study addresses the impact of management commitment on firm performance through supply chain integration, supply chain practices, and green supply chain management. The study employed a quantitative approach, and data collection was conducted among 80 manufacturing companies in Indonesia. The data were analyzed using partial least squares (PLS) with SmartPLS software version 4.0. The study results indicate that management commitment influences supply chain integration, supply chain practices, and the adoption of a green supply chain approach. Companies can optimize the role of external partners in supply chain integration, thereby influencing supply chain practices and the development of green supply chains. However, this study reveals that supply chain integration did not directly improve firm performance. Moreover, the results indicate that supply chain practices, such as building strategic partnerships and increasing information sharing, cannot directly improve firm performance. The company implements a green supply chain by evaluating environmental care programs, building awareness among customers to use environmentally friendly products, and consistently offering environmentally friendly products, which can improve firm performance. The practical contribution of research provides enlightenment to manufacturing industry practitioners, motivating them to commit to developing employees and enhancing their skills as human capital assets. Theoretical contribution to enriching the theory of the green environment in producing economic and environmental performance.
