Abstract

Asset and inventory management in higher education institutions is a crucial aspect of supporting academic operational efficiency. At Universitas Muhammadiyah Kotabumi (UMKO), the current inventory recording system and lending procedures are still conducted conventionally, leading to risks of data inaccuracy, slow information retrieval, and the potential loss of physical lending forms. This study aims to design and develop an integrated inventory and goods lending information system utilizing Quick Response (QR) Code technology. The system development method employed is the Waterfall model. This method was selected based on the characteristics of inventory systems that require structured development stages and comprehensive documentation. QR Code technology is implemented to automate item identification and accelerate lending transactions through mobile device scanning. The result of this research is a web-based application capable of providing real-time asset data, facilitating item tracking, and generating accurate inventory reports. The implementation of this system is expected to minimize human error, increase asset management transparency, and support the modernization of digital infrastructure within Universitas Muhammadiyah Kotabumi for more professional services.

Abstract

This research is motivated by the suboptimal state of exam simulation media for students at SMK N 2 Kotabumi in preparing for the Joint Entrance Examination for State Universities (SBMPTN), where conventional tryout processes result in slow and inaccurate data processing. As a solution to these issues, this study designs a web-based tryout application developed using the Waterfall method through the stages of requirement analysis, design, coding, and systematic testing. The application is designed to simulate the Computer Assisted Test (CAT) mechanism in real-time, thereby providing instant and transparent assessment feedback for both students and the school. The results of this research are expected to provide an effective self-simulation platform to enhance academic readiness and the accountability of student learning evaluations at SMK N 2 Kotabumi, ultimately achieving a more competitive graduation quality at the national level.

Abstract

The management of public health data at the district level still faces significant challenges, including manual reporting processes, data redundancy, and delayed information aggregation. These issues are also observed in the North Lampung District Health Office, where monthly health reports are still processed using fragmented and unintegrated systems. This study aims to design and implement a web-based monthly health reporting information system to improve data accuracy, integration, and reporting efficiency. The system was developed using the Rapid Application Development (RAD) method, which emphasizes iterative development and active user involvement. The system integrates health center data, disease classification (ICD-10), and LB1 morbidity reporting into a centralized platform equipped with real-time dashboards. Software evaluation was conducted using black-box testing and white-box testing, including cyclomatic complexity and code coverage analysis. The results indicate that all functional modules operate correctly, with code coverage exceeding 87% across all components. The system successfully reduces reporting time, improves data consistency, and enhances decision-making support for health authorities. Therefore, the proposed system provides an effective and reliable solution for digital transformation in regional health reporting systems.
