This study conducts sentiment analysis of Indonesian user reviews of the CapCut application using IndoBERT and compares two evaluation schemes: a single 80/20 train–test split and stratified 5-fold cross-validation (k=5). A total of 1,048,575 reviews were collected from the Google Play Store through web scraping and labeled into three sentiment classes based on rating: negative (1–2), neutral (3), and positive (4–5). After preprocessing—cleaning, case folding, banned-word removal, normalization—and duplicate removal, 517,962 reviews were retained. IndoBERT Base P1 was fine-tuned using fixed hyperparameters (batch size 32, learning rate 2e-5, up to 4 epochs, early stopping patience 2), while undersampling was applied to the training set to address class imbalance. Performance was assessed using accuracy, precision, recall, F1-score, and ROC-AUC, supported by confusion matrix and ROC-curve visualizations. The single split achieved an accuracy of 0.756, whereas cross-validation produced a mean accuracy of 0.740. Across both schemes, the positive class achieved the best performance (F1-score 0.850; ROC-AUC 0.918–0.919), while the neutral class remained the most challenging (precision 0.198–0.206; F1-score 0.280–0.283). Overall, cross-validation is recommended for reporting because it reduces dependence on a single partition and provides a more representative estimate across multiple splits.

This study explores ethical investment practices among Catholic institutions in Indonesia. As a relatively rare area of inquiry, the research investigates the extent to which Catholic institutions have sought to translate the principles of Catholic Social Teaching (CST) into the field of investment. Data were collected through interviews with key participants from three dioceses and six congregations. The findings reveal that these institutions have endeavored to implement ethical principles derived from CST. Due to limitations in their capacity to conduct screening and analysis of various investment options, they have adopted a strategic approach by utilizing the services of an investment consultancy team from the Indonesian Bishops’ Conference (KWI). Drawing on Max Weber’s theoretical framework, this practice is interpreted as a form of social action grounded in “value-rationality.” Thus, investment activities pursued rationally for financial gain are framed within the values of CST. In this way, Catholic institutions have sought to establish faith-based ethical investment practices.
