SMA Negeri Lewa Tidahu is one of the educational institutions that conducts the process of admitting new students, an annual activity that is still carried out manually. However, with the current development of digital media, nearly every group across various age levels requires fast internet connectivity. The issues faced include inefficient document management, frequent errors by prospective students in filling out manual registration forms, and unclear writing on the forms submitted to the school, making them difficult for operators to read. This results in inefficiency in terms of time and inaccuracies in data entry. Therefore, it is necessary to develop a new student admission system that allows students to access detailed information. This system is designed using the System Development Life Cycle (SDLC) model, which includes stages such as requirements analysis, design, programming, Black Box testing, SUS evaluation, and maintenance. The implementation of this new student admission system will simplify the process for users.

This study aims to examine the implementation of teaching strategies and methods at SDN 1 Gobras using a qualitative approach supported by NVivo 15 software. Data were collected through in-depth interviews, direct observations, and documentation to evaluate the effectiveness of student-centered learning methods, such as a modified Problem-Based Learning (PBL) approach. The findings reveal that kinesthetic strategies significantly enhance students’ learning enthusiasm, particularly in lower grades (grades 1-3). However, the study also identifies key challenges, including limited learning resources and time allocation. To address these issues, continuous teacher training and improved learning facilities are recommended. These findings are expected to serve as practical guidance for elementary schools in enhancing the quality of learning effectively.

This study explores the barriers and challenges organizations face when implementing green management practices. Through a qualitative approach involving in-depth interviews with 15 key informants and document analysis, the research reveals complex interconnections between organizational, resource-related, and external barriers that impede successful implementation. The findings highlight a "green management commitment paradox" where surface-level support for environmental initiatives, without corresponding structural changes, hinders implementation efforts. The study identifies three primary barrier categories: organizational resistance and leadership commitment issues, resource allocation challenges, and external regulatory pressures. The research contributes to both theory and practice by providing a nuanced understanding of how these barriers interact and influence implementation success. The findings suggest that organizations need to adopt a holistic approach to environmental management, considering both technical and social dimensions of change to achieve effective implementation of green management practices.

Lean Management is a method that emphasizes reducing waste and increasing added value in healthcare service processes. Through a systematic literature review, this study identifies various aspects of Lean implementation in hospitals, such as reducing patient waiting times, optimizing resource utilization, and improving patient satisfaction. The findings reveal that Lean Management implementation not only supports operational efficiency but also enhances service quality and patient experience. The success of this method heavily depends on management support, active staff involvement, and adequate training. This study also highlights challenges such as resistance to change and budget constraints. These findings have significant implications for hospital managers and policymakers in formulating strategies to improve healthcare service effectiveness. Recommendations for future research include empirical studies examining Lean implementation in various hospital contexts, particularly in developing countries. This study aims to explore and analyze strategies for improving hospital operational efficiency through the Lean Management approach.

Digitalization has become a transformative force reshaping how organizations innovate and sustain competitive advantages in an interconnected global economy. This study explores the intricate relationship between business digitalization, innovation capabilities, and sustainability outcomes. Employing a comprehensive literature review, it examines how digital transformation fosters innovative practices and supports sustainable business models. Key findings reveal that integrating digital technologies, such as artificial intelligence, IoT, and blockchain, significantly enhances innovation capacity by accelerating product development cycles, improving decision-making precision, and fostering collaborative innovation ecosystems. Moreover, digitalization optimizes resource utilization, minimizes environmental impact, and strengthens stakeholder engagement, contributing to measurable economic, environmental, and social sustainability outcomes. The synergy between digital transformation and sustainability initiatives provides organizations with strategic advantages, including improved operational efficiency, customer loyalty, and competitive positioning. However, challenges such as implementation barriers, balancing digital-sustainable priorities, and managing unintended environmental impacts persist. Future research should focus on empirical validation, industry-specific applications, and longitudinal studies to further elucidate the pathways through which digitalization supports sustainable innovation and long-term business resilience. This study underscores the imperative for organizations to strategically align digital transformation with sustainability objectives, ensuring their future success in a rapidly evolving business environment.
