Evaluating the Effectiveness of the SIGNAL Digital Samsat Application Using the PIECES Framework and Technical Testing
No full textThe SIGNAL application is a digital service provided by the Indonesian National Police\u27s Traffic Corps (Korlantas Polri) to facilitate online STNK validation. However, several users have reported issues such as unsuccessful verification processes, delays in the delivery of physical documents, slow customer service responses, and login difficulties. This study aims to evaluate the performance of the SIGNAL application using the PIECES framework, which covers six dimensions: Performance, Information, Economic, Control, Efficiency, and Service. Data were collected through questionnaires distributed to 300 users of the SIGNAL application. Each questionnaire indicator was developed based on PIECES theory and statistically tested for validity and reliability using AVE and Composite Reliability. Descriptive and inferential analyses were conducted, including a one-sample t-test to assess user satisfaction. The results show that the average satisfaction score was 3.9 out of 5, with 76% of respondents expressing satisfaction or high satisfaction, 15% neutral, and 9% dissatisfied. The highest satisfaction was recorded in the Economic aspect (mean 4.06), while the lowest was in Control (mean 3.94). Technical testing using Apptim showed the app performed well, with an average response time of 2.4 seconds, CPU usage at 18%, memory usage at 170MB, and no crashes (0% error rate). These findings indicate that SIGNAL is generally effective and stable, though improvements are needed, particularly in service responsiveness and cross-device performance. This research contributes to the theoretical application of the PIECES model in evaluating public digital services and offers insights for improving the quality of e-government systems in Indonesia
Sentiment Analysis of the Film "JUMBO" on Twitter Using the Naive Bayes Method and Support Vector Machine (SVM) with a Text Mining Approach
No full textThis study aims to perform sentiment analysis on reviews of the film “JUMBO” collected from the Twitter platform, using the Naive Bayes and Support Vector Machine (SVM) methods. The data were gathered through a crawling process on Twitter, yielding 2,011 tweets, which were then processed through several pre-processing steps, including case folding, cleaning, normalization, tokenization, stopword removal, and stemming. Subsequently, the data were transformed into numerical representations using TF-IDF, followed by sentiment labeling into positive, negative, and neutral categories. For the Naive Bayes method, training and evaluation were conducted using 5-fold Cross Validation. The results showed that the Naive Bayes model achieved an accuracy of 80.60%, precision of 73.83%, recall of 73.50%, and an F1-score of 69.98%. Meanwhile, the SVM method obtained an accuracy of 75.87%, precision of 76.36%, recall of 62.45%, and an F1-score of 65.64%. Compared to the baseline random classifier, which only achieved an accuracy of 32.47%, both primary methods significantly outperformed it in classifying film review sentiments. The analysis also indicates that the F1-score is lower than the accuracy due to the imbalanced data distribution, with a considerably higher number of positive reviews. This study also presents visualizations of sentiment distribution and word clouds to provide a clearer understanding of audience opinions. The results demonstrate that the Naive Bayes method performs well and has potential for use in sentiment analysis of films on social media platforms. These findings are expected to provide valuable insights for the creative industry, particularly in evaluating audience responses and improving the quality of future film productions.This study aims to perform sentiment analysis on reviews of the film “JUMBO” collected from the Twitter platform, using the Naive Bayes and Support Vector Machine (SVM) methods.
