Abstract

Abstract: This research aims to develop a Web-Based Library Profile Information System for SMA Negeri 7 Sijunjung to facilitate the dissemination and access of library information. The research used the Research and Development (R&D) method with the Rapid Application Development (RAD) model. The system was developed using Laravel 12 and MySQL. Testing was conducted using White Box, Black Box, expert validation, and user testing. The Black Box testing results showed that all system functions were valid, while testing by 3 experts obtained an average score of 91.00% and testing by 20 users obtained 90.75%, both categorized as very good. These results indicate that the system is feasible to use as a digital library information medium.

Abstract

Computer fault diagnosis at SMKN 2 Padang Panjang is currently performed manually and relies on a single technician, resulting in lengthy identification and repair processes. Furthermore, the lack of organized records regarding computer fault history hinders the tracking of failure patterns in specific units. This study aims to develop a web-based expert system utilizing the Forward Chaining method to assist in computer troubleshooting and diagnosis based on user-reported symptoms. The research employs the Research and Development (R&D) approach with the Rapid Application Development (RAD) model, comprising the stages of Requirements Planning, User Design, Construction, and Cutover. A knowledge base (rule base) is automatically generated from training data using the C4.5 Decision Tree algorithm and subsequently processed via a Forward Chaining inference engine. The system incorporates QR Code features for unique computer identification and a diagnosis history log. System validation involved Black Box Testing, White Box Testing, expert evaluation, and user testing. Black box and white box testing results confirmed that all system functions operated according to the design. Expert evaluation yielded an average score of 95.8% (categorized as highly valid), while testing with 25 users demonstrated a 96% alignment between the system's diagnoses and those of experts. These results demonstrate that the developed web-based expert system is effective, valid, and suitable for use as an initial diagnostic tool for computer troubleshooting in a school laboratory environment.

Abstract

Course timetable preparation in the Information Technology Study Program at Universitas PGRI Sumatera Barat is still performed in spreadsheets, typically requires three to five days, and can produce instructor, class, or room conflicts. This study develops a web-based scheduling information system that centralizes timetable data, detects collisions automatically, and offers alternatives with support from the Google Gemini API. Development followed the Waterfall System Development Life Cycle, comprising requirements analysis, design, implementation, testing, deployment, and maintenance. The application was built with PHP, Laravel, and MySQL. A deterministic rule identifies overlapping allocations involving the same instructor, class, or room on the same day. Gemini is used only to rank and explain feasible candidates; the application revalidates each recommendation, and the Study Program Secretary retains final approval. Black-box testing of ten functions achieved a 100% success rate. Beta testing produced an average score of 89.22% from three experts and 89.79% from two users, with both results classified as Very Good. The findings indicate that the system is highly feasible for integrated course timetable preparation and administration.

Abstract

The development of information technology in education encourages schools to optimize activity management systems more effectively and efficiently. One important activity in schools is extracurricular activities, which serve as a forum for developing students' interests, talents, and character. However, the selection and registration process for extracurricular activities at SMKN 1 Talamau is still carried out manually using paper forms, which presents various challenges such as the risk of data loss, slow recording processes, and difficulties in data management and recapitulation. Therefore, a solution is needed in the form of a digital system that can improve the effectiveness of extracurricular activity management at the school. This research aims to develop a web-based extracurricular selection information system at SMKN 1 Talamau. The research method used is Research and Development (R&D) with the System Development Life Cycle (SDLC) development model. The development stages included requirements analysis, system design using the Unified Modeling Language (UML), implementation using the PHP, HTML, CSS, and JavaScript programming languages, and system testing through alpha and beta testing. The results showed that the web-based extracurricular selection information system was declared successful in the alpha testing. Furthermore, the beta testing, conducted by expert validation, yielded excellent results with an average score of 89.81%, and the user beta testing yielded an average score of 93.83%, a very good rating. Therefore, the implementation of this system is expected to improve the effectiveness of extracurricular management and support digital transformation in school education management.
