KLASIFIKASI KOMENTAR JUDI ONLINE MENGGUNAKAN INDOBERT
The rapid growth of social media has enabled the misuse of comment sections as a medium for promoting online gambling. The high volume of comments makes manual moderation ineffective, thus requiring an automated classification system. This study aims to develop a classification system for online gambling comments using the IndoBERT model and to evaluate its performance based on accuracy, precision, recall, and F1-score metrics. IndoBERT was selected due to its ability to understand contextual meaning bidirectionally and its pre-training on a large Indonesian corpus, making it effective in handling informal language variations in social media comments. The dataset used in this study consists of 20,807 Indonesian-language comments and was expanded to 50,000 data points through data augmentation techniques. The dataset was divided into 80% training data, 10% validation data, and 10% testing data. Furthermore, a fine-tuning process was conducted using six hyperparameter scenarios, including learning rate, batch size, and number of epochs. The best performance was achieved in Scenario 5 with a learning rate of 3e-5, batch size of 32, and 3 epochs, resulting in accuracy, precision, recall, and F1-score values of 98.68%.
