Abstract

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.

Abstract

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.

Abstract

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 ecommerce 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.

Abstract

The management of waste banks often encounters issues such as manual transaction processing, limited transparency, and low public participation in waste sorting and recycling. This study presents the development of a web-based application for the Tonsea Recycle Center (TRC) aimed at improving operational efficiency, data transparency, and user engagement through a point-based reward mechanism. The development process adopted the Personal Extreme Programming (PXP) methodology, encompassing stages of requirement analysis, system design, implementation, testing, deployment, and maintenance. The application was developed using HTML, CSS, Python, Django, and SQLite, and includes features such as user authentication, transaction management, a reward point system, and an administrative dashboard[1]. Functional testing, user acceptance testing (UAT), and security testing were conducted to evaluate the system. The results demonstrate that the application effectively overcomes the limitations of the manual system by automating transaction records, enabling real-time data access, and enhancing transparency. Positive user feedback from UAT confirmed the system’s usability and functionality. This research concludes that the TRC web application significantly contributes to improving waste bank operations and community involvement. Future enhancements are suggested, including integration with digital payment systems, AI-based waste classification, and mobile application development to increase system accessibility and utility.
