Abstract

The growing use of social media as a platform for public communication has opened new opportunities for understanding public opinion regarding government policies, including public services. One of the cities actively discussed on social media is Surakarta, where citizens openly express both appreciation and criticism of local government performance. This study aims to analyze public sentiment toward public services in Surakarta by employing a deep learning-based sentiment analysis approach, specifically using the Bidirectional Long Short-Term Memory (BiLSTM) model. Data were collected from Twitter/X using a web crawling technique with the keywords “pemerintah solo” (Solo government), “kota Surakarta” (Surakarta city), and “kota solo” (Solo city), resulting in 2,168 tweets. The analysis process involved several stages, including preprocessing, sentiment labeling using a lexicon-based method, feature representation with Word2Vec, and classification using five models: SVM, Random Forest, CNN, LSTM, and BiLSTM. The evaluation results show that BiLSTM achieved the best performance with an accuracy of 90.21%, precision of 91.05%, recall of 89.84%, and F1-score of 90.43%. The conclusion of this study is that BiLSTM can effectively classify public sentiment toward public services, especially in the context of informal social media texts. The implication of this research indicates that sentiment analysis can serve as a decision-support tool for designing more responsive and data-driven public policies and provide strategic insights for local governments in improving the quality of public services.

Abstract

Purpose: This study aims to analyze the effectiveness of the IndoBERT model for sentiment analysis of Indonesian anguage YouTube comments related to the legal Court’s ruling on the minimum age of vice presidential candidates for 2024. While previous research applied conventional machine learning methods, this study addresses the challenge of understanding nuanced public opinion using a language-specific transformer model. Methods: A dataset of 23,796 YouTube comments was collected using the YouTube Data API in January 2025. The comments underwent extensive preprocessing including normalization, case folding, text cleansing, symbol removal, stopword elimination, and stemming. Sentiment labels (positive, negative, neutral) were assigned through a lexicon based approach. Three models IndoBERT, BERT, Support Vector Machine (SVM), and Random Forest were trained and tested using an 80% and 20% split. Model result was evaluated with accuracy, precision, recall, and F1-score metrics. Result: IndoBERT achieved the maximum result with 95% accuracy, outperforming BERT 92%, SVM 88%, and Random Forest 85%. This confirms IndoBERT’s superior ability to capture contextual nuances in Indonesian sentiment analysis compared to other models. Novelty: This research demonstrates the advantage of transformer based models, particularly IndoBERT, in analyzing complex Indonesian social media texts. The findings support the use of IndoBERT for automated sentiment monitoring to inform government and media responses. Future work could extend to broader discourse analysis across diverse public sectors.

Abstract

Era digital menempatkan anak-anak dalam lingkungan teknologi yang intensif, sehingga literasi digital menjadi fondasi penting untuk pembentukan karakter yang bijak dan bertanggung jawab. Penelitian Pengabdian kepada Masyarakat (PkM) di BA Aisyiyah Duwet, Sukoharjo, bertujuan mengatasi kesenjangan pemahaman literasi digital di kalangan guru dan orang tua serta dampaknya pada karakter anak. Metode deskriptif kualitatif dengan observasi, wawancara, dokumentasi, dan pelatihan tatap muka melibatkan 40 peserta. Program mencakup sosialisasi, pelatihan intensif, pendampingan, dan evaluasi pre-test dan post-test. Hasil menunjukkan peningkatan signifikan pada semua aspek literasi digital peserta, seperti pemahaman konsep literasi digital naik dari 45% ke 85%, kemampuan media sosial produktif dari 50% ke 80%, dan keterampilan desain konten dari 30% ke 75%. Peningkatan ini mencerminkan keberhasilan program dalam membangun etika digital dan penggunaan teknologi yang sehat. PkM ini berhasil mengubah pola pikir peserta menjadi lebih positif terhadap teknologi sebagai alat pendidikan karakter.
