Abstract

Breast cancer is a leading cause of cancer-related mortality worldwide, necessitating the identification of reliable biomarkers for prognosis and targeted therapy. This study employed an integrative bioinformatics and statistical approach to analyze differentially expressed genes (DEGs) in breast cancer using datasets GSE70947 and GSE22820 from the gene expression omnibus (GEO). A protein-protein interaction (PPI) network was constructed to identify hub genes, followed by functional enrichment analysis to determine their biological significance. Survival analysis using the KMplot database revealed that CDC45, KIF2C, CCNB1, KIF4A, CENPE, CHEK1, KIF15, AURKB, NCAPG, and HJURP were significantly associated with poor prognosis. These genes were primarily enriched in cell cycle regulation, mitotic spindle organization, and DNA damage response, highlighting their role in tumor progression. Among them, CCNB1, CHEK1, and AURKB were strongly linked to cell cycle progression and checkpoint regulation, while KIF2C and CENPE played essential roles in mitotic division. High expression levels of these genes correlated with reduced overall survival, suggesting their potential as prognostic biomarkers and therapeutic targets in breast cancer.These discoveries help us better understand how breast cancer develops and point to potential targets for tailored treatments.

Abstract

Online counseling has transformed mental health services by offering a convenient and cost-effective alternative to traditional in-person therapy. This study investigates the role of technology in counseling by analyzing user reviews of the Bicarakan.id app from the Google Play Store. A machine learning approach was employed to identify critical patterns and themes within the reviews. Text pre-processing methods such as tokenization, stop-word removal, and TF-IDF vectorization were applied to a dataset of 125 user reviews. The Elbow method helped determine the optimal number of clusters, which was three. Clustering performance was assessed using the Silhouette score, with three clusters yielding the highest average score of 0.4939, indicating a moderate level of clustering effectiveness. Cluster 1 primarily contained positive reviews, emphasizing user satisfaction with the app's services. Cluster 2 included more specific feedback on users' experiences with counselors and app features. Cluster 3 focused on the app's accessibility and ease of use while raising concerns about data privacy and the lack of offline consultation options. The study underscores the significance of using user feedback to enhance and improve technology-driven mental health solutions.

Abstract

This study examines the factors hypothesized to contribute to school dropout rates in disadvantaged regions of Papua Province and explores potential geographical influences. The primary aims are to derive parameter estimates and statistical tests for the model of underdeveloped regions in Papua using Geographically Weighted Regression (GWR) and to determine the factors influencing school dropout rates in these areas, providing a basis for governmental policy development to mitigate school dropout issues in disadvantaged regions. Findings reveal that the highest dropout rates occur at the junior high school level, with indications of spatial clustering in dropout cases due to heterogeneity among observation sites. This suggests that regions with elevated dropout rates, or conversely low rates, are likely to have neighboring areas with comparable patterns, necessitating the use of spatial regression modeling with a Fixed Gaussian Kernel function. GWR analysis resulted in two clusters based on significant variables, which include the student-teacher ratio at the junior high school level, the student-classroom ratio at the junior high school level, and the elementary school dropout rate (APTs).

Abstract

Fenomena kotak kosong dalam Pilkada 2024 menjadi perbincangan ramai di Twitter, memunculkan pandangan pro dan kontra di masyarakat mengenai keberadaan calon tunggal yang dinilai berpotensi memengaruhi stabilitas politik di daerah. Diskusi publik di media sosial umumnya menggunakan bahasa informal, dialek bahasa daerah, serta tidak mengikuti kaidah baku, sehingga menyulitkan analisis manual dan berisiko menimbulkan bias. Maka dari itu, penelitian ini mengimplementasikan pendekatan deep learning dengan memanfaatkan model Long Short-Term Memory (LSTM) dan word embedding GloVe. Proses pelabelan dilakukan secara otomatis menggunakan Indonesia Sentiment Lexicon (INSET) untuk mengklasifikasikan sentimen masyarakat terhadap kebijakan kotak kosong berdasarkan data Twitter. Data penelitian terdiri dari 2.168 tweet yang diperoleh melalui teknik crawling, kemudian dievaluasi menggunakan metode 10-fold cross-validation. Analisis sentimen menghasilkan distribusi opini publik, yaitu 35,9% negatif, 32,8% positif, dan 31,3% netral. Hasil pengujian menunjukkan akurasi tertinggi sebesar 94,93% pada fold ke-6, dengan rata-rata akurasi keseluruhan mencapai 90,08%. Penelitian ini berkontribusi dalam pengembangan sistem analisis berbasis deep learning untuk pemantauan opini publik, serta menunjukkan potensi data media sosial sebagai sumber informasi strategis dalam memahami persepsi masyarakat terhadap fenomena politik.
