Abstract

The Directorate General of Immigration launched the M-Paspor app for online passport applications. Although it has been downloaded more than 1 million times, its 2.5 rating indicates user dissatisfaction. Review analysis is necessary for developers to understand the issues and improve the app to enhance the overall user experience. Therefore, this study conducts sentiment analysis on M-Paspor app reviews using a combination of Bidirectional Encoder Representations from Transformers (BERT) embedding and LSTM to classify user opinions. The advantage of BERT lies in its ability to understand the deep context of text, while LSTM excels in handling sequential data. LSTM is used as a classification method because it can capture long-term patterns in sequential data through memory management with cell states and three main gates, enabling it to continuously understand sentence context to support sentiment analysis. In this study, labeling consists of three classes: positive, negative, and neutral, using the lexicon method. The LSTM-BERT model shows consistent and higher accuracy values with a smaller proportion of training data. Testing results with a confusion matrix show the highest accuracy of 91.33% on a 70%:30% data split.

The research method used is a quantitative type with descriptive nature with multiple linear analysis, with purposive sampling technique. Quantitative analysis includes validity and reliability tests, basic assumption tests, classical assumption tests, and hypothesis testing using the f and t test as well as the coefficient of determination (R2) analysis test and then distributing questionnaires to 383 @AdaKopi Parung Bogor consumers. Distribution of questionnaires using a 5-scale Likert scale with research testing using the SPSS 25 instrument test. The results are (H1) lifestyle towards purchasing decisions of tvalue 4.296> t table 1.966 H0 rejected Ha accepted. (H2) store atmosphere on purchasing decisions of tvalue 5.831> t table 1.966 H0 rejected Ha accepted. (H3) Service quality on purchasing decisions is tvalue 9,025> t table 1,966 H0 rejected Ha accepted. (H4) together, the size of the contribution of lifestyle, shop atmosphere and service quality to purchasing decisions is F value 342.505> F table 2.63 H0 is rejected Ha is accepted, it means that lifestyle, shop atmosphere and service quality jointly affect the purchase decision products at @AdaKopi Parung Bogor
