This study explores the significant role of digital trust and transparency in fostering customer loyalty in online banking services. As the financial sector increasingly shifts towards digital platforms, understanding the dynamics of customer retention becomes crucial for banking institutions. The research adopts a quantitative approach, using a survey questionnaire distributed to over 200 participants with experience in digital banking services. The findings reveal that both digital trust and transparency are pivotal in shaping customer loyalty. Specifically, digital transparency-in areas such as data security, privacy, and operational clarity-was found to have a stronger correlation with customer retention than trust alone. The study emphasizes that transparency not only boosts customer confidence but also strengthens long-term loyalty by reducing perceived risks and uncertainties. Additionally, the research highlights that customer engagement, driven by transparent communication and reliable services, plays a significant role in mediating the relationship between transparency and loyalty. The study further discusses the implications for banking institutions, suggesting that focusing on transparent practices, clear communication about security measures, and data usage can lead to enhanced customer satisfaction and long-term retention. Future research could investigate the impact of cultural differences on digital trust and transparency in banking, as well as explore the role of emerging technologies like blockchain in furthering transparency and trust in financial transactions.

This study explores human complexity and its impact on macroeconomic development. The main focus is on the buyer's mental variables, such as financial assumptions and courage, and how these elements influence business utilization and behavior. Information from measured studies and investigations shows that positive monetary assumptions will often strengthen financial movements, while vulnerabilities or negative assumptions can hinder monetary developments.

To compete with other stores, store owners need to design various strategies, one of which is understanding customer purchase patterns. This article examines the Squeezer algorithm and compares the performance of the Apriori and FP-Growth algorithms in forming customer purchase association patterns that can be used as a reference for store owners in planning sales strategies. The data mining process was carried out using Association Rules and Clustering methods. A total of 1256 sales transaction data samples were analyzed to understand the association patterns produced by each method. Based on the test results with a minimum support of 0.2 and a confidence of 0.6, the Apriori algorithm produced 194 association rules with a total rule strength of 1.16. Meanwhile, the FP-Growth algorithm produced 52 association rules with the same total rule strength of 1.16. The Clustering Method resulted in 7 clusters with a similarity value of 0.06322. After comparison, the FP-Growth algorithm proved to have better performance in generating association rules compared to the Apriori algorithm.

Children under five are more at risk of experiencing nutritional disorders because during this period children will experience very rapid growth and development. Nutritional disorders can result in children's performance in activities not being optimal, hampering the growth and development process, and can even cause disease. Malnutrition sufferers in Indonesia are increasing every year, and the percentage of malnutrition in Indonesia is around 3.4%. An expert system is a computer-based system built based on facts, knowledge and reasoning that can help solve a problem. However, to measure the uncertainty and level of expert confidence in identifying and detecting malnutrition, an expert system can use the Dempster-Shafer method. The results of testing the system model using the Dempster-Shafer method on toddler nutritional diseases obtained quite good results with system accuracy of 84% with a precision value of 81.83% and also a recall value of 80%.
