Abstract

This study analyzes public sentiment regarding candidates in the 2024 DKI Jakarta Gubernatorial Election utilizing a Support Vector Machine (SVM) approach. Recognizing the pivotal role of social media, particularly Twitter, in shaping public opinion, the research addresses the challenges of processing large volumes of unstructured data. Through systematic data preprocessing and feature extraction, the SVM model was applied, achieving a sentiment classification accuracy of 70%. The analysis revealed a distribution of sentiments where 36.1% of comments were positive, 33.4% negative, and 30.5% neutral. These findings illustrate the complexities of public discourse surrounding key political events, highlighting the model's efficacy and the nuances of sentiment detection. Moreover, discussions on model limitations elucidate areas for enhancement, suggesting future avenues including the adoption of more sophisticated algorithms and improved data processing techniques. This research contributes to the understanding of voter sentiment dynamics in a significant electoral context, providing insights that may assist campaign strategies and political analyses in Indonesia.

Abstract

Web 3.0 presents challenges in efficient data exchange, especially in decentralized systems. REST API (HTTP/1.1) remains widely used due to its broad compatibility but has communication inefficiencies, while gRPC (HTTP/2) offers better performance with multiplexing and Protocol Buffers. This study compares REST API and gRPC under various traffic conditions and data sizes using Apache JMeter and Wireshark, measuring throughput, response time, latency, and data transfer efficiency. Results show that REST API has higher throughput in low-traffic scenarios (995 vs. 29.5 req/min) and faster GET response time (3 ms vs. 20 ms), while gRPC excels in large data transfers (276.34 KB/s vs. 134.1 KB/s) and stable latency (0.147 ms). However, ANOVA analysis (p > 0.05) indicates no statistically significant difference. REST API is ideal for standard web applications, while gRPC is suited for microservices and real-time systems.

Abstract

Named Entity Recognition (NER) in the biomedical domain faces complex challenges due to the variety of medical terms and their context of use. Transformer-based models, such as SciBERT, have proven to be effective in natural language processing (NLP) tasks in scientific domains. However, the performance of these models is highly dependent on proper hyperparameter selection. Therefore, the aim of this study is to analyse the impact of hyperparameter tuning on the performance of SciBERT in NER tasks on the NCBI Disease Corpus dataset. The methods used in this study include training the baseline SciBERT model without tuning, followed by hyperparameter optimisation using grid search, random search, and bayesian optimisation methods. Model evaluation is done with precision, recall, and F1-score metrics. The experimental results showed that of the three methods grid search and random search produced the best performance with a precision, recall and F1-score of 0.82, improving from the baseline which only achieved a precision and recall of 0.72 and F1-score of 0.68. This study confirms that proper hyperparameter tuning can improve model accuracy and efficiency in medical entity extraction tasks. These results contribute to the development of optimisation methods in biomedical text processing, particularly in improving the effectiveness of the SciBERT Transformer model for NER.

Abstract

The advancement of information technology has significantly impacted various sectors, including digital banking. BRImo, a mobile banking application from Bank Rakyat Indonesia (BRI), has been widely used, generating numerous user reviews that reflect their experiences. This study applies IndoBERT, a transformer-based model specifically designed for the Indonesian language, to analyze sentiment in BRImo user reviews. IndoBERT excels in handling the unique characteristics of the Indonesian language, such as informal and mixed-language usage. The dataset was collected from Kaggle and processed through labeling, data balancing, and splitting into 80% training, 10% validation, and 10% testing data. The IndoBERT model was evaluated using a confusion matrix and achieved 90% accuracy, with F1-scores of 0.89 for negative, 0.91 for neutral, and 0.90 for positive sentiments. Sentiment analysis results indicate that a significant portion of negative reviews highlight issues related to login difficulties, transaction failures, and slow customer service response times. These insights can help BRI enhance application reliability and customer support efficiency. This study demonstrates that IndoBERT is effective in sentiment analysis for Indonesian text and can be utilized to enhance BRImo services by providing deeper insights into user feedback.

Abstract

Smoking is a common habit in Indonesia. The Indonesian government has implemented regulations on smoke-free areas, but violations of the smoke-free policy still often occur. Previous studies have developed smoking violation detection system based on the MQ sensor. However, the smoking violation detection system based only on the MQ sensor is less reliable because the detected gas could come from other sources. Therefore, this study discusses a smoking violation detection system that can automatically verify smoking violation activities using the MQ-7 sensor, MQ-135 sensor, and the YOLOv5s algorithm. The MQ-7 sensor that has been calibrated to detect CO in ppm units achieved an accuracy level of 89.84%. The MQ-135 sensor also has successfully detected ammonia and toluene in cigarette smoke in ppm units. The trained YOLOv5s algorithm achieved an average Precision of 91.9%, Recall 83.7%, F1-Score 87.6%, and mAP50 88.3%. The system is equipped with a speaker that will sound automatically after a verified smoking violation occurs and Telegram notifications in the form of text messages and images.

Abstract

Technology, hardware and software are developing rapidly as time goes by. One of the results of this rapid technological development is Augmented Reality (AR) technology. Current tools in augmented reality (AR) were offered by Vuforia Software Development Kit (SDK). However, with the rapid development of Unity Engine, now we can integrated OpenCV in Unity Engine. This integration presents ideas for the development of AR technology. This study uses an approach that uses research and development (R&D) methodology. The model that will be used is the utilization of the ADDIE development framework. We encountered three main problems, problems faced are "How many stages of implementing AR with mediapipe in Unity Engine?", “How people satisfaction while using this product?” and " What is the maximum distance and time required to conduct the interaction process?". From the research conducted, we found that there are four important AR development stages that must be carried using Unity Engine and OpenCV. Next for RQ2 we got a level of approval from users of 86.53% or strongly agree with what we are doing. Then for the last RQ, we got the results for optimal hand detection distance is 3 meters, and the speed with the fastest value is 0.098s.

Abstract

This research implements YOLO v11 for image-based waste detection and classification to improve waste management efficiency. The model recognizes four categories of waste: inorganic, organic, hazardous and residual. The training results showa mAP@0.5 of 0.989 and a maximum F1 of 0.98 at an optimal confidence level of 0.669. The model had high precision on the Organic (0.995) and B3 (0.991) classes, but faced difficulties in classifying the Residue category. The confusion matrix revealed most of the predictions were accurate, despite some misclassification. The model also showed stable performance under various lighting and background conditions. With this reliability, YOLO v11 can be applied in automated sorting systems to improve recycling efficiency and support sustainable environmental management, although further improvements to data augmentation and class weight adjustment are still needed.

Abstract

The performance of registration information systems is a crucial factor in ensuring the efficiency and effectiveness of academic administrative services. This study evaluates the quality of a registration information system based on the ISO 9126 standard, focusing on key aspects such as functionality, reliability, usability, efficiency, maintainability, and portability. The data collection methods used in this study vary based on each quality aspect. For the usability and maintainability aspects, data was collected through a questionnaire distributed to 100 respondents, consisting of students, prospective students, and academic staff. For the efficiency aspect, the GTMetrix tool was used to evaluate website performance. The reliability aspect was tested using the WAPT application. The functionality aspect was assessed using black-box testing with a total of 10 participants consisting of 2 prospective students, 5 students, and 3 administrative staff members, while portability was evaluated by accessing the website on five different mobile devices with varying screen sizes, operating systems, and types. The evaluation results indicate that the system performs well in functionality, usability, portability, reliability and maintainability but requires significant improvements in efficiency, particularly in LCP optimization. Based on these findings, optimization strategies such as image compression, CSS and JavaScript minification, and server-side caching implementation are recommended.
