Abstract

Bank is a business entities that have the function of collecting funds and distributing them from and for the community. The service of a bank is said to be good not only from bank’s point of view, but also from customer’s opinion as a service user. The problem that occurs is when bank has not been able to meet good and appropriate service standars, resulting in customers feeling dissatisfied. This study aims to analyze customer satisfaction to find out how the quality of service is available and to help provide information regarding what steps should be taken to improve service quality Service Quality method and Customer Satisfaction Index. The stages in this research include surveys, literature studies, preparation and distribution of questionnaires, validity and reliability tests, gap analysis and percentage of satisfaction levels, writing results, and finally conclusions. The results show that there are 15 attributes with negative gap values and a satisfaction percentage of 80,38%. Based on these results, customers are satisfied with the service provided

Abstract

This study aims to develop and evaluate a stock price prediction model for Bank Central Asia (BBCA) using a multivariate Long Short Term Memory (LSTM) approach. The model utilizes four key variables from historical stock data open, high, low, and close prices and is compared to a univariate model that uses only the closing price as input. The research process includes data preprocessing, LSTM architecture design, model training over 200 epochs, and performance evaluation using MAE, RMSE, and MAPE metrics. The results demonstrate that the multivariate LSTM model provides higher predictive accuracy, achieving a MAPE of 2.41%, outperforming the univariate model which recorded 2.71%. Moreover, the multivariate model shows better stability across validation and test data, and greater adaptability in capturing market dynamics. Prediction result visualizations support these findings, with the multivariate model producing more consistent forecasts that closely follow actual data. These results suggest that integrating OHLC variables enhances prediction accuracy and model reliability. This study contributes to the advancement of stock price prediction systems based on deep learning and serves as a valuable reference for investors and decision-makers in designing more data-driven investment strategies.
