Web-Based Guest Lecture Information System for Committee and Student Users at FMIPA UNSRAT

Andrea Emailly Sumakul — 2026-06-30

Guest lecture management at FMIPA UNSRAT currently suffers from significant fragmentation across WhatsApp, Google Forms, and paper attendance, leading to data duplication, information inconsistencies, and administrative inefficiency. This condition hinders effective decision-making and stakeholder engagement. This study aims to design and develop a centralized Web-Based Guest Lecture Information System to integrate the entire event lifecycle, including publication, registration, digital attendance, and reporting. The system was developed using the Waterfall model with Laravel framework and MySQL database. Comprehensive evaluation involved Black Box Testing, User Acceptance Testing (UAT) with committee members, and User Perception Testing with students. Results indicate a 100% success rate in Black Box Testing across 42 functional scenarios. UAT yielded a 90.4% acceptance rate among committee members, validating operational feasibility and workflow alignment. Furthermore, User Perception Testing achieved a 91.04% satisfaction score among students, with Behavioral Intention reaching 93.6%. These findings demonstrate that the system significantly reduces data fragmentation and improves administrative efficiency compared to manual processes. The system is deemed feasible for immediate deployment, offering a robust solution for centralized academic event management. However, limitations exist regarding financial module integration. Future work should focus on API integration with the central university portal and automated honorarium processing to further enhance scalability and institutional adoption.

Design and Usability Evaluation of a Web-Based Car Service Monitoring System at FocusAuto

Darlene Syaroon Asalui — 2026-06-30

FocusAuto Repair Shop currently relies on manual WhatsApp updates for service status, resulting in delayed responses, inconsistent information, and limited transparency for customers. This condition reflects a broader challenge in information system adoption among Indonesian MSMEs. This study aims to design and implement a web-based car service monitoring system using the Rapid Application Development (RAD) method and evaluate its usability using the System Usability Scale (SUS). The system was developed through four RAD stages: Planning, Design, Construction, and Implementation, utilizing Laravel, Bootstrap, and MySQL. Key features include real-time status tracking, customer data management, and PDF invoice generation. System functionality was validated through Black-box testing involving 18 test scenarios for admin and customer modules. Usability was evaluated using the SUS questionnaire distributed to 10 FocusAuto customers. Results indicate that all 18 test scenarios passed successfully, confirming system reliability and functional compliance. The usability evaluation yielded an average SUS score of 85.25, categorizing the system as Excellent. These findings demonstrate that the developed system effectively replaces manual communication methods, significantly improving service transparency and operational efficiency at FocusAuto. The study concludes that web-based monitoring systems enhance customer satisfaction in automotive MSMEs. Future work recommends cloud deployment and WhatsApp API integration to further maximize accessibility and automation.
