Abstract

The rapid growth of digital transformation in public institutions has underscored the urgency of developing effective and user-friendly digital archiving systems. In Indonesia, many government agencies, including the Regional Financial and Asset Management Agency (BKAD) of Kapuas Regency, still face inefficiencies in manual document management, with retrieval times averaging 15–20 minutes per file and high risks of data loss. This study aims to design and evaluate a web-based digital archive system that integrates information systems engineering with mathematical usability assessment, thereby addressing both functional and experiential challenges. The research employed the Design Thinking framework, progressing through empathize, define, ideate, prototype, and testing stages. Prototypes were developed using high-fidelity design tools, while usability evaluations combined subjective and objective measures through the System Usability Scale (SUS), Mission Usability Score (MIUS), and Maze Usability Score (MAUS). The findings demonstrate that the proposed system reduced retrieval times by 90 percent (from 20 minutes to 2 minutes) and achieved an SUS score of 82.5 (Excellent), a MIUS of 76.2 (Good), and a MAUS of 78.6 (Good), all surpassing benchmarks reported in previous studies. These results confirm that combining user-centered design with quantitative evaluation yields reliable outcomes. The study concludes that the hybrid evaluation framework provides both theoretical and practical contributions, while recommending further research on advanced features such as AI-based classification and large.

Abstract

Manual inventory processes at PT Borneo Sejahtera Medika resulted in an 18.2% stock discrepancy rate, frequent expired items, and delayed procurement decisions. This study develops and empirically evaluates a web-based inventory management system integrating real-time monitoring, automated expiration alerts, and demand forecasting. A six-month before–after analysis was conducted to measure system impact using discrepancy rate, operational performance indicators, and forecasting accuracy metrics. The results show that the discrepancy rate decreased from 18.2% to 13.6%, representing a relative improvement of 25.27%. Operational performance improved significantly, with stock checking time reduced by 52%, expired items reduced by 57%, and emergency procurement reduced by 31%. The forecasting module achieved a Mean Absolute Percentage Error (MAPE) of 5.00%, indicating acceptable short-term prediction accuracy. These findings demonstrate that the implemented system provides measurable improvements in data accuracy, operational efficiency, and inventory control within a healthcare distribution context.

Abstract

Waste management in schools is an important effort to develop environmental awareness among students from an early age. However, many students still lack awareness and habits in identifying and recording the types and quantities of waste generated in their daily activities. Therefore, an educational medium based on digital technology is needed to support students in understanding and managing waste more effectively. This community service activity aimed to implement a mobile-based application for recording waste using the 3R (Reduce, Reuse, Recycle) principle in the school environment. The methods used in this program included socialization, environmental education, and demonstrations on how to use the application for students and teachers at Sekolah Islam Al-Azhar BSD@Cileungsi, Bogor Regency. The mobile application introduced in this activity provides several main features, including user registration and login, input of waste types such as organic, inorganic, and hazardous waste (B3), and daily waste data recapitulation. The results of the activity indicate that the implementation of the mobile application increased students’ understanding and awareness of waste management while encouraging active participation in applying the 3R principles within the school environment. In addition, the application helps organize waste recording more systematically and allows easier monitoring by the school management. Therefore, the implementation of a mobile-based waste recording application can serve as an innovative solution to support environmental education and improve waste management practices in schools.
