Abstract

This study aims to develop a web-based digital attendance system with dual validation using QR Code, selfie verification, and geolocation to improve the accuracy, efficiency, and transparency of student attendance recording at SMK Negeri 1 Bojonegoro. The study employed a Research and Development (R&D) method using the ADDIE model, which consists of the stages of analysis, design, development, implementation, and evaluation. The trial subjects included 35 students, 1 teacher, and 1 school operator. Data were collected through observation, interviews, documentation, and questionnaires. The system quality was evaluated using the ISO/IEC 9126 standard, which includes functionality, reliability, usability, efficiency, and maintainability, while user satisfaction was measured using a Likert scale. The results showed that the system was successfully developed and could be used according to the school's needs. The system quality test obtained an average score of 4.1 (good category), while the user satisfaction level achieved an average score of 3.9 (good category). The system is considered capable of simplifying the attendance process, accelerating access to attendance data, reducing the potential for attendance fraud, and supporting real-time attendance monitoring. Therefore, this web-based digital attendance system is feasible to be used as a more effective attendance solution in the school environment.

Abstract

The rapid development of digital technology has encouraged the integration of interactive learning media to improve students' understanding of abstract concepts. This study aimed to develop a web-based interactive learning media for Computer Networking subjects and evaluate its validity, practicality, and effectiveness in improving students' conceptual understanding. The study employed the Research and Development (R&D) method using the Four-D (4D) model, consisting of Define, Design, Develop, and Disseminate stages. The participants included one material expert, one media expert, one vocational school teacher, and 30 tenth-grade students of SMK Al-Muhammad Cepu. Data were collected through observations, interviews, validation sheets, practicality questionnaires, and pretest-posttest assessments. The developed learning media integrates digital learning materials, instructional videos, interactive quizzes, automatic scoring, and learning progress reports within a web-based platform. The validation results indicated that the media achieved an average score of 4.38 from the media expert and 4.50 from the material expert, both categorized as highly valid. Practicality assessment showed excellent results, with teacher and student responses reaching 100% and 88.4%, respectively. Furthermore, the effectiveness test produced an N-Gain score of 0.91, indicating a high improvement in students' conceptual understanding. These findings demonstrate that the developed web-based interactive learning media is valid, practical, and effective for supporting Computer Networking learning in vocational high schools.
