Abstract

User reviews provide important insights into the quality of digital banking applications; however, their large volume makes manual analysis inefficient. This study applies Aspect-Based Sentiment Analysis (ABSA) to examine user perceptions of the BYOND by BSI application based on three aspects: interface, features and performance, and services. Three classification algorithms were compared: Naïve Bayes, Support Vector Machine (SVM), and Random Forest, evaluated with accuracy, precision, recall, F1-score, and ROC-AUC. The results indicate that SVM and Naïve Bayes achieved the best performance, with an accuracy of 0.95 and an F1-score of 0.92, whereas Random Forest exhibited slightly lower performance with an F1-score of 0.89. Furthermore, sentiment analysis reveals the features and performance aspect exhibits the highest proportion of negative sentiment (39.6%), primarily associated with system reliability issues, login problems, transaction failures, and application instability. These findings demonstrate that ABSA can serve as an effective knowledge discovery approach for identifying critical functional issues and supporting data-driven prioritization in improving digital banking services, particularly within the context of sharia banking applications.

Abstract

The rapid rise of startups in Indonesia makes user reviews on the Google Play Store a valuable data source for understanding user perceptions and satisfaction. These unstructured reviews contain insights supporting product development and business strategies. This study analyzes sentiments in Indonesian startup app reviews and compares two classification methods: TF-IDF + Linear SVM and fastText, implemented using Google Colab. Reviews were collected in September 2025 using google-play-scraper; 4,000 reviews were retrieved and refined into 3,152 unique reviews after cleaning and preprocessing. Sentiment labeling used ratings (1–2 negative, 4–5 positive); because the neutral class was limited, this study focuses on balanced binary classification with 1576 positive and 1576 negative reviews. The process involves data scraping, text preprocessing, model training, and evaluation using accuracy, precision, recall, and F1-score metrics, with Linear SVM chosen as an efficient baseline for high-dimensional sparse TF-IDF features. Results show that fastText achieves 91.88% accuracy and an F1-macro of 0.9184, slightly outperforming TF-IDF + SVM (F1-macro 0.9103), suggesting that the embedding-based approach better captures semantic nuances of Indonesian text. Future work may extend this study to ABSA to assess sentiments toward price, UI/UX, and customer service for deeper technopreneurship insights in Indonesia.

Abstract

Transformasi menuju ekonomi digital di Indonesia dihadapkan pada tantangan krusial berupa meningkatnya serangan fraud yang semakin canggih. Penelitian ini mengajukan sebuah pendekatan unsupervised learning untuk mengenali pola serangan fraud generasi baru sebagai dasar penguatan kapasitas supervisi institusional. Penelitian ini berfokus pada identifikasi anomali tanpa bergantung pada label historis yang ada dengan memanfaatkan algoritma ensemble Isolation Forest. Model berhasil memetakan karakteristik transaksi yang mencurigakan berkat penerapan rekayasa fitur yang mendalam, yang mencakup analisis perilaku, korelasi alamat, dan ekstraksi sinyal dari IP. Hasil evaluasi menunjukkan bahwa pendekatan unsupervised ini mampu mengidentifikasi 18% dari total kasus fraud yang telah dilabelkan, membuktikan relevansinya dalam menangkap sinyal serangan yang sesungguhnya. Lebih penting lagi, analisis kualitatif terhadap anomali yang ditemukan berhasil mengkarakterisasi sebuah Pola Serangan Senyap, yaitu kombinasi multi-faktor risiko yang berpotensi terlewatkan oleh sistem deteksi konvensional. Temuan ini menyajikan sebuah wawasan baru bagi institusi regulator untuk beralih dari supervisi reaktif ke penemuan ancaman proaktif, yang pada akhirnya mendukung terciptanya ekosistem keuangan digital yang aman dan berkelanjutan sejalan dengan Tujuan Pembangunan Berkelanjutan (SDGs).

Abstract

Customer churn prediction is a crucial aspect of the banking industry for maintaining customer loyalty and reducing the cost of acquiring new customers. This study aims to develop a web-based decision support system capable of predicting potential customer churn using the Gradient Boosting Machine (GBM) algorithm. The dataset used is the Bank Customer Churn Dataset, consisting of 10,000 customer records with 14 attributes. The research stages include exploratory data analysis and preprocessing, which involves data cleaning, categorical feature encoding, feature engineering (BalanceSalaryRatio, TenureByAge, CreditScoreGivenAge), and data balancing using SMOTE to address class imbalance. The GBM model was trained on the balanced dataset and evaluated using accuracy, precision, recall, and F1-score metrics. The evaluation results show that the model achieved an accuracy of 83.95%, with a recall of 67.32% for the churn class, indicating a strong capability in identifying customers at risk of churn. Feature importance analysis reveals that Age and NumOfProducts are the most dominant features, contributing approximately 77% to the prediction. The model was then implemented in a Flask-based web application with an HTML and CSS interface, enabling non-technical users to perform real-time churn predictions. This system is expected to assist banking institutions in designing more targeted and data-driven customer retention strategies.

Abstract

Credit card transaction fraud detection is commonly treated as a binary classification problem, whereas operational risk management requires more detailed risk-level information to support investigation prioritization. This study proposes a hybrid machine learning framework for transaction risk stratification. In the first stage, the K-Means algorithm was applied to the training set to discover latent risk structures and generate cluster-based risk labels. Subsequently, a Random Forest model was trained to predict risk levels for new transaction data. To maintain evaluation objectivity, the dataset was divided into training, validation, and testing sets, and data leakage prevention mechanisms were implemented. The testing results show that the model was able to consistently classify two levels of risk with stable precision, recall, and F1-score values. In the binary fraud detection scenario, the model achieved an accuracy of 0.8831. These findings indicate that separating latent risk exploration from predictive classification can produce a more informative risk representation compared to conventional binary approaches. However, this study is still limited to a single public dataset and one classification model. Therefore, the generalizability and potential performance improvements of the model still need to be evaluated by experimenting with other algorithms.

Abstract

Online Travel Agent (OTA) applications have become increasingly popular in supporting digital travel services; however, the quality of the user experience may vary across different applications. This study aims to compare the user experience of the Agoda and Traveloka applications among university students using the User Experience Questionnaire (UEQ) and to examine the influence of the six UEQ dimensions on user satisfaction using SmartPLS. A quantitative research approach was employed using purposive sampling among students at Universitas Sriwijaya. The primary dataset consisted of 100 evaluations from Agoda users and 100 evaluations from Traveloka users, following a pilot test involving 30 participants. The results of the UEQ benchmark comparison indicate that Traveloka outperformed Agoda in the dimensions of Attractiveness, Stimulation, and Novelty, whereas Agoda achieved higher scores in Perspicuity, Efficiency, and Dependability. A statistically significant difference between the two applications was identified only for the Stimulation dimension (p = 0.026). The SmartPLS analysis, conducted after indicator elimination, produced R² values of 0.207 for Agoda and 0.374 for Traveloka. For the Traveloka model, Stimulation was found to have a positive and significant effect on user satisfaction (t = 2.166, p = 0.030), whereas none of the structural paths in the Agoda model were statistically significant. These findings suggest that Traveloka provides a more engaging and motivating user experience than Agoda. Nevertheless, both applications require further improvement in their pragmatic quality dimensions, as indicated by the UEQ benchmark results.

Abstract

The increasing adoption of digital technologies, particularly those powered by Artificial Intelligence (AI), has accelerated the development of applications aimed at improving service quality and user experience, one of which is the FotoYu application. This study aims to evaluate user satisfaction with the FotoYu application using the End-User Computing Satisfaction (EUCS) model, which comprises five dimensions: Content, Accuracy, Format, Ease of Use, and Timeliness. A quantitative research approach was employed using a survey method, with questionnaires distributed to 145 FotoYu users selected through purposive sampling. The collected data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with SmartPLS software. The results indicate that all measurement indicators satisfied the required validity and reliability criteria, confirming that the research instrument was appropriate for assessing user satisfaction. The structural model evaluation produced an adjusted R² value of 0.784, indicating that the five EUCS dimensions collectively explained 78.4% of the variance in user satisfaction, while the remaining 21.6% was attributable to factors outside the proposed research model. Furthermore, the effect size (f²) analysis revealed that Content had the strongest influence on user satisfaction, followed by Ease of Use, Format, Timeliness, and Accuracy. These findings demonstrate that the EUCS model is an effective approach for evaluating user satisfaction with the FotoYu application while providing valuable insights to support service quality improvement and enhance the overall user experience.
