Abstract

At SMPN 1 Lebakwangi, the teaching and learning process of science subjects in class VIII has utilized media such as books and videos, with identical exercises and quizzes given to all students. However, this approach faces challenges due to the limited variety of learning media and practice questions, which rely heavily on textbooks. As a result, students often struggle to absorb and understand the material effectively, finding the learning process less interesting and diverse. This research aims to develop alternative learning media in the form of an educational application that focuses on the human digestive system. The app incorporates the Fisher-Yates algorithm to randomize quiz questions, ensuring that students receive different sequences of questions. The system was developed using RUP (Rational Unified Process) methodology, and the design was made with UML (Unified Modeling Language). User Acceptance Test (UAT) results show the effectiveness of the application, with scores of 91.66% for appearance, 92.47% for material content, 89.74% for learning process, and 91.77% for improving understanding. This educational app serves as an interactive, engaging, and diverse learning medium, offering alternative practice questions that improve understanding of human digestive system material.

Abstract

This research aims to implement Security Information and Event Management (SIEM) in the Kuningan University academic system. The security of information systems in the educational environment, especially in university academic systems, is becoming increasingly important considering the availability of sensitive data, such as student personal information and academic data which must be properly protected. Security threats such as cyber attacks are increasingly complex and can often be detrimental to both universities and system users. In this research, we apply SIEM as a solution to detect, prevent and respond to security threats to the Kuningan University academic system. The system development method is used with the steps of system requirements analysis, system design, system implementation, system testing, and system evaluation. The output of this research is an increase in the security level of Kuningan University's academic system. By implementing SIEM, the system is expected to be able to quickly and effectively detect potential security threats, improve response to security events, and provide reports that are useful for making decisions. Thus, it is hoped that the results of this research can make a significant contribution in improving security and data protection in the Kuningan University academic system, as well as becoming a reference for other educational institutions in maintaining increasingly complex information security defenses.
