Abstract. Unmanned Aerial Vehicles (UAVs) are increasingly utilized for package delivery due to their efficiency and automation capabilities. UAVs can execute autonomous flight missions using Global Positioning System (GPS)-based navigation. However, challenges arise in the final stage of delivery, known as the last-mile delivery problem. The limitations of GPS-based navigation, the absence of recipient authentication, and shifting drop-off points create reliability and safety concerns. External factors such as varied environmental topography further contribute to delivery inaccuracies, highlighting the need for a more precise approach. Purpose: Many studies have explored UAV navigation and delivery systems, but challenges in last-mile delivery remain unresolved. This research introduces an improved UAV delivery system using computer vision (CV) and image-based visual servoing (IBVS) with QR Codes as location markers. The aim is to enhance UAV navigation accuracy and recipient verification, ensuring more reliable package deliveries. Methods/Study design/approach: The study implements a CV-based navigation system where QR Codes serve as landing markers for UAVs. Image processing is conducted using a companion computer linked to the UAV's flight control system. The IBVS method enables UAVs to adjust their position in real-time, minimizing GPS errors. Recipient verification is performed through QR Code scanning before releasing the package. The system is tested through computer simulations and real flight experiments to assess accuracy and effectiveness. Result/Findings: Experimental results demonstrate that UAVs equipped with the IBVS method can successfully complete package delivery missions with improved accuracy. GPS errors are corrected by aligning the UAV's position with QR Code markers, and recipient authentication is verified before package release. Real-flight tests confirm that this approach significantly enhances UAV delivery reliability compared to conventional GPS-based navigation. Novelty/Originality/Value: This research presents a novel integration of computer vision and UAV navigation for addressing last-mile delivery challenges. By leveraging IBVS and QR Code-based authentication, UAVs can perform fully autonomous, precise, and secure package deliveries. This method offers a viable solution to improve UAV-based logistics, reducing delivery errors and enhancing operational safety.

Abstract. With the rapid growth of technology, educational institutions are constantly looking for ways to improve their services and enhance student performance. One of the significant challenges in higher education is predicting the graduation outcome of students. Predicting student graduation can help educators and academic advisors to provide early intervention and support to students who may be at risk of not graduating on time. In this paper, we propose a hybrid 2D convolutional neural network (CNN) and synthetic minority over-sampling technique (SMOTE) to predict the graduation outcome of students. Purpose: Knowing the results and how the Hybrid 2D Convolutional Neural Network (CNN) and Synthetic Minority Over-sampling Technique (SMOTE) algorithms work in predicting student graduation predicates. This algorithm uses a dataset based on family background variables and academic data. Methods/Study design/approach: This study uses the Hybrid 2D CNN algorithm for the classification process and SMOTE for the minority class over-sampling. Result/Findings: The prediction accuracy of the model using SMOTE is 96.31%. Meanwhile, the model that does not use SMOTE obtains an accuracy of 95.32%. Novelty/Originality/Value: This research shows that the use of a Hybrid 2D CNN algorithm with SMOTE gives better accuracy than without using SMOTE. The dataset used also proves that family background and student academic data can be used as a reference for predicting student graduation predicates.

Abstract. Toxic comments on social media pose serious challenges to online safety and moderation efforts. These comments are often multilabel in nature and suffer from class imbalance, making them difficult to classify accurately using standard methods. Purpose: This study investigates the use of three transformer-based language models, BERT, RoBERTa, and ALBERT, for multilabel toxic comment classification through fine-tuning. The main objective is to address class imbalance and evaluate model performance after data augmentation. Methods/Study design/approach: The Toxic Comment Classification dataset, consisting of six overlapping labels, was used in this study. A data augmentation strategy was applied using synonym replacement techniques from WordNet and easy data augmentation (EDA) to increase the representation of minority classes. After balancing the data, the dataset was split into training, validation, and testing sets. Each transformer model was fine-tuned using the Hugging Face Transformers library with the same hyperparameter settings. Model evaluation was conducted using accuracy, precision, recall, and both micro and macro F1-scores. Result/Findings: The RoBERTa model achieved the best performance, with 86.73% accuracy and a micro F1-score of 92.35%, outperforming BERT and ALBERT. The macro F1-score also improved significantly compared to previous studies using imbalanced datasets, indicating better recognition of minority classes such as threat and identity hate. Novelty/Originality/Value: This study highlights the effectiveness of combining text data augmentation with transformer-based models in handling multilabel classification tasks involving imbalanced data. The use of simple augmentation methods notably improves performance and fairness across labels, contributing to the development of more robust toxic comment detection systems.
