Abstract

Social media facilitates user communication, both in positive, negative and neutral aspects. One of the popular platforms today is Tiktok, where users can create short videos and interact through comments or private messages, as well as follow the latest news, including the major conflict between Palestine and Israel that has been going on since 1948. In this war, many Palestinian civilians, including children and the elderly, became victims, and are currently trying to flee to Rafah to seek protection. This study aims to analyze public sentiment towards the news of Palestinian refugees heading to Rafah, using two classification methods: Naive Bayes and Decision Tree. Before classification, the data goes through a preprocessing process and TF-IDF weighting, and the two methods are compared to determine the best accuracy. The results showed that the Naive Bayes Multinomial method with the application of SMOTE produced an accuracy of 85.43%, a precision of 86.22%, a recall of 85.43%, and an f1-score of 85.53%. Meanwhile, the Decision Tree C4.5 method with the application of SMOTE produced an accuracy of 94.23%, a precision of 94.58%, a recall of 94.23%, and an f1-score of 94.22%. Based on the evaluation results, the best method for sentiment analysis of the hashtag #SaveRafah is Decision Tree C4.5.

Abstract

Work safety in the construction environment is highly dependent on the correct use of personal protective equipment (PPE). This study aims to develop an automatic PPE detection system using a YOLO-based deep learning model to improve supervision and compliance with PPE use in the field. Two variants of the YOLO model, namely YOLOv10 and YOLOv11, were tested and their performance was compared through a fine-tuning process using custom dataset consisting of 16,568 annotated images of construction workers wearing various types of PPE. The model was evaluated using precision, recall, and mAP50. The results showed that the YOLOv11s model performed the best with with an mAP50 of 0.718 and a precision score of 0.804, indicating good detection and classification ability. This model is able to detect various types of PPE effectively, so it can be used as a tool in real-time occupational safety monitoring. This study proves that the application of YOLO-based deep learning technology can be an effective solution to improve compliance with PPE use and reduce the risk of work accidents in the construction sector. The implications of this study open up opportunities for the development of more sophisticated and adaptive automatic monitoring systems in the future such as deploying the model on edge devices for real-time inference and expanding detection capabilities to include additional safety violations such as the absence of safety harnesses or proximity to hazardous zones.

Abstract

The rapid erosion of intangible cultural heritage, exemplified by the declining engagement of youth with the Riau Malay Persembahan Dance, poses an urgent challenge to the continuity of regional identity and values. This research responds by developing a mobile game designed to preserve and revitalize this traditional dance through digital media. The study employs a structured Research and Development (R&D) methodology integrated with the Game Development Life Cycle (GDLC), ensuring both scientific rigor and authentic cultural representation. Game design and development involved iterative prototyping, expert validation, and user testing, with data collected via structured surveys, interviews, and direct observation. The game was evaluated by 35 participants from diverse backgrounds, whose feedback demonstrated high levels of engagement and cultural appreciation. Statistical analysis using a chi-square test (X2=399.25, df=3, p<0.0001) confirmed overwhelmingly positive reception, with 85% of participants reporting increased interest in Riau Malay culture after gameplay. Despite limitations such as platform exclusivity and a narrow cultural focus, the results underscore the game’s effectiveness as an educational tool and its potential for broader implementation. This research contributes a replicable model for digital cultural preservation, demonstrating that interactive media can significantly enhance the transmission and appreciation of intangible heritage among younger generations.

Abstract

Education is an important aspect in forming the potential of the young generation where the use of mobile platforms has become an integral part of everyday life. Over time, gadgets have become an access to learning besides books. Therefore, the increasingly complex development of the technological world encourages individuals to be able to apply technology in all their activities. Mathematics learning at elementary school level is often faced with challenges to make the learning process more fun and interactive. A common problem among students in Indonesia is that mathematics is considered a difficult subject. Monotonous learning reduces students' interest in learning. Therefore, designing learning games for elementary school students, especially in mathematics learning, can be an innovative solution to improve the quality and attractiveness of learning with interactive learning media. This research aims to create a game that allows students to learn more effectively which focuses on game development using the Game Development Life Cycle (GDLC) development model. This research produces a translation game from mathematics book learning material with the theme "Counting Numbers Up to 10,000" using the Unity 3D game engine which functions well and the application of the Game Development Life Cycle (GDLC) method also functions well.
