Abstract

Inspecting the completeness of student uniform attributes is challenging because several items, suchas epaulettes, name tags, belts, black shoes, and caps, may appear small, partially occluded, orvisually unclear. This study compares YOLOv8n and SSD MobileNet for detecting student uniformattributes using a self-collected dataset. The dataset contains 1,532 augmented images, five objectclasses, and 5,294 YOLO-format bounding box annotations. The experimental procedure includeddataset preparation, object annotation, train-validation-test splitting, model training, and finalevaluation on the test set. The evaluation used precision, recall, mAP@50, mAP@50-95, inferencetime, and FPS. On the test set, YOLOv8n achieved a precision of 0.8966, recall of 0.8689, mAP@50of 0.9276, mAP@50-95 of 0.6723, inference time of 10.36 ms, and 96.47 FPS. SSD MobileNetachieved a precision of 0.5140, recall of 0.5169, mAP@50 of 0.6034, mAP@50-95 of 0.3171,inference time of 11.00 ms, and 90.87 FPS. These findings indicate that YOLOv8n performed betterin the tested dataset and experimental setting.

Abstract

Continuance Use Intention refers to a condition in which users are satisfied with their experienceof using an information system, thereby encouraging them to continue using the system consistentlyin the future. Access by KAI is the official mobile application developed by PT Kereta ApiIndonesia (PT KAI) that provides online railway ticket booking services. However, the applicationhas experienced several challenges, including a decline in its user rating since its launch in 2023, arelatively low number of active users, and unresponsive customer support services. This study aimsto provide practical recommendations for improving the application based on an analysis using theExpectation Confirmation Model (ECM), particularly through enhancements to the application'suser interface (UI) and user experience (UX) design. The study adopts a modified ECM byincorporating four additional constructs: system quality, service quality, information quality, and habit. The research population consists of Access by KAI users residing in the Greater Jakartametropolitan area (Jabodetabek), with a sample of 400 respondents selected using purposivesampling. Data were analyzed using the Partial Least Squares–Structural Equation Modeling(PLS-SEM) approach implemented in SmartPLS 4. The findings indicate that continuance useintention is at a strong level, with an explanatory value of 0.733 (73%). Furthermore, perceivedusefulness, habit, and satisfaction were identified as significant determinants of continuance useintention. The proposed interface redesign is expected to serve as a practical implementation of thestudy's recommendations and assist PT KAI in prioritizing the development of application featuresthat better address users' needs and expectations

Abstract

PT. Ruang Raya Indonesia (Ruangguru) is an educational technology company focused on evelopingdigital learning platforms in Indonesia. One of the primary systems supporting its operations is SuperCMS, a content management systems designed to managed data and activities related to privatetutoring sessions between students and Masters teachers. Based on the findings of the observation, theexisting system still encounters several chalengges, including limited data integartion, the lack ofcomprehensive information displays, and workflows that are not yet fully efficient. To address theseissues, this study conducted the analysis and design of an information system using the waterfallmethodology. This approach consisted of data collection through observation and literature review,system requirements analysis, and systems modeling using the Unified Modeling Language (UML).The primary objective of this research is to design a Super CMS that can manage private tutoring sessions in a more informative, efficient, and integrated manner. The results indicate that the proposedSuper CMS design is capable of integrating scheduling, attedance tracking, assessment, andcommunication process into a single centralized platform. Furthermore, the develop user interfacefeatures a consistent design and intuitive navigation. The proposed system has the potential to improvethe effectiveness of data management, accelerate coordination among users, and provide o solidfoundation for future system implementation
