Abstract

The library is a learning infrastructure that must be available in every school. Libraries provide information and knowledge needed by students. The development of technology and information is expected to have an impact, namely the efficiency and effectiveness of the implementation of work. One way is to change the manual system into a computer-assisted system supported by internet technology. In this community service activity, a web-based library application has been designed and built at SMAN 1 Jombang. Application development uses the Waterfall model which consists of 4 stages, namely system requirements analysis, system design, implementation, and maintenance. The library application is built using the Code Ignaiter framework with the Hypertext Pre-Processor (PHP) programming language while the database uses MySQL.The benefit of this application is to address the needs of students for book searches and book ordering, while for school library officers it manages the circulation of book borrowing and reporting. The result of community service that has been implemented is a Web-based library application at SMA Negeri 1 Jombang to improve the quality of library management.DOI: https://doi.org/10.26905/abdimas.v6i2.5173

Abstract

Dengue Fever Transmission is a serious, potentially fatal infectious if unmanaged disease. It caused by the dengue virus, transmitted by Aedes aegypti and Aedes albopictus mosquitoes. In West Java, cases remain high and fluctuate significantly, requiring precise mathematical modeling to describe transmission dynamics. This is the first study applying Ensemble Kalman Filter (EnKF) in West Java to estimate the SEIR-SI model, compared to Unscented Kalman Filter (UKF), using dengue fever transmission case data from 2010–2023. Performance was assessed via Mean Absolute Percentage Error (MAPE) for the infected human population ( ), showing EnKF’s superior accuracy (2.4%) over UKF (7.8%). EnKF effectively estimates hard-to-measure epidemiological variables and this study can support government prediction-based dengue fever transmission control policies.
