Analysis of Transaction Patterns and User Preferences in the DANA Application Using the Apriori Algorithm for Digital Wallet Service Optimization
type: item
description: DANA emerges as a practical solution for conducting fast, efficient, and secure financial transactions. However, its rapid growth presents a new challenge for developers: understanding user transaction patterns and behavior in depth. Each user has different preferences and habits; some regularly use the bill payment feature, others more frequently perform top-ups and purchase mobile credit, while some utilize the balance transfer feature. Data processing results reveal that the combination of Top-Up and Electricity Bill payments has a support value of 60% and a confidence of 85.7%. In contrast, the combination of Electricity Bill Payment ke Top-Up shows the highest confidence value of 100%. This indicates that almost all users who pay electricity bills will always top up their balance before transacting. Analyzing these transaction patterns is crucial as it provides valuable insights for developers to optimize features, enhance service personalization, and design user behavior-based promotional strategies.

Sentiment Analysis of Public Perception Towards Electric Cars in Indonesia Using the Naïve Bayes Algorithm
type: item
description: The development of electric cars in Indonesia shows significant improvement alongside government efforts to reduce carbon emissions and promote renewable energy use. Public perception and opinions of electric cars are important factors influencing interest in owning these environmentally friendly vehicles. This study aims to analyze public sentiment toward electric cars in Indonesia using review data and comments from the social media platform X (Twitter). Data was collected through web scraping techniques and stored in CSV format for further processing using Google Colab. Preprocessing was performed to clean the text data, including removal of punctuation, numbers, symbols, Indonesian stopwords, tokenization, and stemming. The text was then converted into numerical representation using TF-IDF vectorization so it could be processed by the Naïve Bayes classification model. The model was then trained and tested to classify sentiment into three categories: positive, negative, and neutral. The results show that the majority of public comments about electric cars were negative, with a percentage reaching approximately 66.5%, while positive comments accounted for 33.5%. Further analysis revealed that negative sentiment was largely related to the relatively high vehicle prices and limited charging infrastructure. The Naïve Bayes model with CountVectorizer proved effective, achieving 78% accuracy, thus making it a reliable tool for sentiment analysis.
