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

2026-03-28T13:54:09+07:00

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

2026-03-28T13:54:09+07:00

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.

Development of Traditional Snack Selection Simulation App Based on MDLC as Nutritional Literacy Media for Housewives

2026-06-30T08:05:01+07:00

The increasing prevalence of Non-Communicable Diseases (NCDs) such as
hypertension and diabetes in Indonesia is closely linked to excessive consumption of Sugar,
Salt, and Fat (GGL). Despite government regulations, nutritional literacy among housewives
who act as primary household food providers remains low, particularly in understanding
complex nutritional labels on traditional snacks. This research aims to develop a nutritional
literacy medium titled "Sendok Sehat," an Android-based simulation application designed
to help housewives monitor and limit GGL intake. The development follows the Multimedia
Development Life Cycle (MDLC) methodology, which includes the stages of concept,
design, material collecting, assembly, testing, and distribution. Data was collected through
direct observation of consignment stalls to build a product database and a literature study
of Ministry of Health Regulation No. 30 of 2013. The application was built using Android
Studio with Kotlin, utilizing Google Sheets as a cloud-based database and Figma for UI/UX
design. The system features a dummy marketplace interface resembling popular e
commerce platforms to ensure ease of use. A core functional feature is the "Warning Page,"
which provides real-time nutritional literacy and restricts transactions if the cart exceeds
the daily safety limits of 50g sugar, 2000mg salt, or 67g fat. Functional validation through
Black Box Testing confirms that all features, including the GGL filter and record-keeping
system, operate according to specifications. This research concludes that "Sendok Sehat"
provides an interactive and practical solution to enhance nutritional literacy, empowering
housewives to make healthier food choices and potentially reducing the risk of NCDs in
Indonesian households.

Extreme Programming Method for Efficient and User-Friendly Web-Based Photo Studio Reservations: Pilvi Project Case

2026-06-30T09:44:57+07:00

The development of information technology has accelerated the digitalization of services across various sectors, including the photography industry. Pilvi Project is a photo studio that offers photography services for various needs, such as graduation photos, ID photos, and more. However, the current reservation process, which is still carried out manually via WhatsApp, presents several challenges, including scheduling conflicts and limited access to service information for users. This study aims to design and develop a web-based photo studio reservation system using the Extreme Programming (XP) methodology. XP was chosen for its iterative and flexible approach, which allows for rapid adaptation to user needs. The system includes key features such as user registration and login, studio reservations based on availability, service package selection, and admin-controlled data management. The result of this study is a structured and organized photo studio reservation website capable of efficiently managing bookings. Based on black-box testing, all system features functioned as intended. Questionnaire results indicated positive user responses, highlighting the system's ease of use and overall user experience. An evaluation by the Pilvi Project team confirmed that the system successfully met their requirements.
