The research focuses on the development and implementation of the EcoViber application to address plastic waste management in school environments, specifically at SDN Perdopo 02. The study aims to tackle the issue of plastic waste accumulation through technological solutions, enhancing environmental awareness and operational efficiency. The application employs the waterfall method for development and features data collection, visualization, and educational tools to promote transparency and accountability. Comprehensive observations and interviews with seven teachers revealed significant improvements in waste management, with approximately 54.95 kg of plastic waste collected from January to April 2024. The findings highlight the practical implications of EcoViber in fostering a culture of environmental stewardship among school stakeholders. Despite its success, the study acknowledges potential biases in data reporting and the limited generalizability of results due to the focus on a single school. Future research should explore diverse settings and refine methodologies to enhance the scalability and long-term impact of EcoViber. Overall, the study demonstrates EcoViber's value as an innovative and effective solution for sustainable plastic waste management in educational settings.

Purpose: This study aims to explore the potential benefits of integrating innovative technology and agile methodologies, precisely the Scrum method and the AppSheet platform, to enhance the efficiency and effectiveness of school exam administration. The research seeks to address the constraints of manual exam administration and investigate the role of technology in providing practical and efficient solutions.
Methods: The study was conducted at Sekolah Indonesia Kota Kinabalu, Sabah, Malaysia, utilizing the Scrum method with the AppSheet platform. The development of the school exam administration application with AppSheet, the low-code development platform (LCDP), using the Scrum method was carried out with a structured and adaptive approach. User stories and use case diagrams were employed to translate user insights into tangible visualizations, ensuring alignment with the intricate needs of the examination committee.
Result: Implementing the Scrum methodology in the development process has proven effective in creating a tailored and efficient application for school exam administration. The application's design and functionality have been carefully crafted to meet the specific requirements of exam administration, including form-filling, data entry, PDF report generation, and user feedback collection. The user survey conducted as part of the development process has provided valuable insights into user experiences, guiding areas for improvement and ensuring a user-centric approach to application development.
Novelty: This study contributes to the field by demonstrating the successful integration of agile methodologies and user-centric design principles in developing a comprehensive solution for school exam administration. The research highlights the potential of innovative technology to revolutionize exam administration for improved educational outcomes, emphasizing the significance of the Scrum methodology and the AppSheet platform in providing a structured yet adaptive approach to application development in the education sector.
