Abstract

This study looks at how consumer decisions are impacted by the digitalization of QRIS, financial literacy, and financial inclusion through lifestyle. The participants in this study are clients of Sharia Bank. Non-probability sampling combined with a purposeful sampling approach was the sample strategy employed in this study. A sample of one hundred participants was used by the researchers. This study included both primary and secondary data. In order to acquire the primary data required by the researchers, the data collection strategy used in this study is the distribution of questionnaires. In this quantitative study, the Partial Least Squares (PLS) method of moderated regression analysis (MRA) and descriptive statistical analysis were employed as data analysis techniques. Based on the test results and discussions that have been described, the following conclusions can be drawn: The digitalization of QRIS has a direct influence on customers' decisions to make transactions using QRIS. Financial literacy has a direct influence on customer decisions. Decisions made by customers are directly impacted by financial inclusion. Decisions about transactions are directly influenced by lifestyle. The digitalization of QRIS does not directly impact lifestyle. Lifestyle is not immediately impacted by financial knowledge. There is no direct correlation between financial inclusion and lifestyle. Lifestyle cannot moderate the relationship between QRIS digitization and consumer decisions, nor does it have an indirect effect. Lifestyle cannot moderate the relationship between financial literacy and client decisions, nor does it have an indirect influence. Lifestyle cannot moderate the relationship between financial inclusion and customers' decisions to transact via QRIS, nor does it have an indirect influence.

Abstract

The rapid growth of e-commerce applications in Indonesia has resulted in a large volume of user reviews. The review contains important information that can be used to understand user satisfaction, complaints, and needs. Therefore, sentiment analysis of e-commerce app reviews is important to support future decision-making. This study aims to explore and compare the performance of the Transformer model and various word embedding methods in analyzing the sentiment of reviews of Indonesian e-commerce applications. The methods used involve extracting review data from the Google Play Store, text preprocessing, and text representation using Word2Vec, FastText, and IndoBERT. Next, this combination of embedding was tested using the Gradient Boosting Classifier as a prediction model. The evaluation was carried out by comparing the accuracy, precision, recall, F1-score, as well as the visualization of the confusion matrix and word cloud for each model. The results of the tests that have been carried out show that all three models have a fairly good ability to recognize positive reviews, with the highest accuracy score of 88% achieved by Word2Vec and FastText. While IndoBERT produces a lower accuracy value of 86%, IndoBERT shows a better balance in recall values and f1-scores for minority classes compared to Word2Vec and FastText. In conclusion, the application of the IndoBERT-based Transformer model is more effective in capturing the context and meaning of sentiment in Indonesian-language e-commerce reviews. These findings are expected to be a reference for the development of a more accurate sentiment analysis system for e-commerce applications in Indonesia.
