Abstract

The rapid growth of Instagram user reviews on the Google Play Store poses challenges in understanding sentiment quickly and accurately. This research aims to develop an automatic sentiment analysis dashboard based on the Indonesian-RoBERTa model. Review data was collected using the google_play_scraper library and analyzed using a fine-tuned model. Fine-tuning was performed on the w11wo/indonesian-roberta-base-sentiment-classifier model using Indonesian tweet datasets during the PPKM period with 23,645 labeled data points (positive, neutral, negative). The preprocessing process included text cleaning, tokenization, and class weighting. Model evaluation used precision, recall, F1-score, and confusion matrix metrics. Test results showed good performance on positive and neutral classes, but performance on the negative class still needs improvement. The dashboard successfully performed scraping, sentiment prediction, and data visualization automatically. This research demonstrates the potential application of transformer-based models in Indonesian language and supports data-driven decision making.

Abstract

Occupational Safety and Health (OSH) is not only important in industrial or office environments, but also in households that have the potential for accidents and health problems. One group that is vulnerable to these risks is housewives, who carry out daily activities at home. The lack of understanding of safety principles at home (safety house) has the potential to cause accidents, such as burns while cooking, slipping while washing, or exposure to household cleaning chemicals. This Community Service Activity (PKM) was carried out in RT 04 RW 13, Tanjung Riau Village, with the aim of increasing housewives' knowledge and awareness regarding the implementation of K3 at home. The methods used were socialization, interactive counseling, and group discussions on the concept of safety house and practices for preventing household accidents. The results of the activity showed an increase in participants' understanding of the importance of risk management at home, as demonstrated by increased enthusiasm, critical questions, and awareness to apply simple preventive measures in daily activities. Thus, this program made a real contribution to building a culture of safety at the household level, especially for housewives as the front line in maintaining the safety and health of their families.

Abstract

The development of digital technology demands increased student programming competency as part of strengthening digital literacy. However, information technology learning in high schools (SMA/SMK) is usually limited to the use of basic software and web programming. The purpose of this community service activity is to improve the skills of SMK Kolese Tiara Bangsa Batam students by teaching them the basics of web programming using HTML, CSS, and JavaScript. The activity was carried out in four stages: preparation, intensive hands-on training, and project-based learning. Evaluation was carried out through pre-tests and post-tests, and program follow-up. The evaluation results showed that the average score increased by 61.6% from 52.4 in the pre-test to 84.7 in the post-test. In addition, 86% of participants were able to complete a simple website project independently. The level of participant satisfaction with the training was very good. The results indicate that the practice-based training approach is effective in improving students' conceptual understanding and technical skills in website development. As a model for continuously strengthening students' digital competencies, this program can be implemented in other schools.
