Abstract

This study aims to examine the key determinants of customer retention in Islamic banking, with a specific focus on Bank NTB Syariah. Five critical factors are analyzed: trust, Islamic business ethics, relationship marketing, service quality, and customer satisfaction. Using a quantitative approach, the research applies Stuctural Equation Modeling (SEM) with Partial Least Square (PLS) method to analyze survey data collected from 220 customers. The results indicate that trust, Islamic business ethics, and relationship marketing significantly and positively influence customer retention. Conversely, service quality and customer satisfaction were found to have no siginificant effect. These findings highlight that ethical compliance and strong relational ties are more influential than traditional service attributes in shaping customer loyalty within Islamic banking. The study contributes to the literature by integrating ethical and relational perspectives into models of customer retention and provides practical guidance for Islamic banks to strengthen customer loyalty through trust-building, adherence to Islamic ethics, and relationship marketing strategis.

Abstract

Sharing customer transaction data is becoming more perceived in e-commerce and retail industries. Even though the act derives benefits for companies, it may end up in certain privacy threats, such as sensitive personal preferences disclosure. Therefore, the data owner should take measures to minimize the threats. Data anonymization is one of the solutions that has been suggested to address the issue. However, there are still underlying problems, specifically in diminishing the amount of information loss and item loss, as well as maintaining data properties of the anonymized dataset. This paper proposes a unique data anonymization scheme called COMATS. It adopts the brood parasitism behavior of cuckoo birds in laying their eggs into host nests. The scheme incorporates item insertion technique and item suppression technique. The robustness of the proposed scheme lies in its strategy for selecting suppressed items and determining the inserted items. To ensure its efficacy, the proposed method is evaluated in several experiments. The experimental results suggest that the COMATS can guarantee privacy protection by reducing the probability of a successful attack. Additionally, it can also reduce the number of item losses and preserve better data utility in comparison to existing data anonymization schemes.

Abstract

Gender bias against women in the workplace persists, including within digital interactions on social media. This study analyzes user sentiment on Platform X regarding women in professional contexts using three machine learning algorithms: Naïve Bayes, Support Vector Machine (SVM), and Random Forest. A total of 2,336 tweets were collected using 14 gender-related keywords and labeled both automatically using the DistilBERT model and manually through contextual interpretation. The automatic dataset was imbalanced (1,823 negative, 479 positive), while the manual dataset was more balanced (1,196 negative, 1,106 positive). After preprocessing and TF-IDF feature extraction, the data were split using the train_test_split method. Evaluation metrics included accuracy, precision, recall, and F1-score. Random Forest achieved the highest accuracy (79%) on automatic labels but showed class imbalance (F1-score: 0.88 for negative, 0.08 for positive). Meanwhile, models trained on manual labels showed more balanced performance with accuracy between 57% and 59%. A web application prototype was developed using Flask to predict sentiment related to workplace gender issues. The findings highlight the importance of balanced labeling and appropriate algorithm selection to build fair and reliable sentiment analysis models, contributing to more inclusive digital discourse on gender equality.
