Abstract

The development of the internet has changed people's lifestyle with the existence of FinTech. One of the popular FinTech innovations is the Flip digital wallet application. In this study, aspect-based sentiment analysis was carried out on Flip user reviews using the naive bayes algorithm. The test results show high accuracy, with an average accuracy of 0.84. The naive bayes algorithm is effective in classifying user reviews based on aspects of speed, security, and cost, with accuracies of 0.80, 0.87, and 0.84, respectively. This research provides important insights for service providers to improve service performance and innovation. The labelling data generated the most sentiment 0 (no sentiment), followed by sentiment 1 (positive) and 2 (negative). Negative sentiments have a high frequency on speed and security aspects, while positive sentiments have a high frequency on cost aspects. Thus, improvements are needed to the security system and speed of the Flip application to increase user satisfaction in these aspects. The naive bayes algorithm can be a useful tool in processing review data on e-wallet applications and similar services.

Abstract

The rapid growth of online transactions in Indonesia has increased the demand for efficient interbank transfer solutions. However, the costs associated with such transactions have become a significant obstacle. Flip, a company with a vision to become a global leader in customer satisfaction-driven services, offers a solution to this challenge. This study proposes an aspect-based sentiment analysis method using the K-Nearest Neighbors (K-NN) algorithm to analyze user sentiment on key aspects, namely speed, security, and the cost of using the Flip application. The results of this research provide valuable information that can be used as a basis to provide insights, suggestions and recommendations to businesses, so they can create better solutions and promote optimal user experience. The research results show that the K-NN model has the ability to predict user psychology well in all aspects, with a significant level of accuracy, specifically speed (73.04%), security (86, 05%) and costs (80.11%). In addition, this study also compares two model validation methods: simple data splitting method and K-Fold cross-validation. Although the simple data splitting method has a higher average accuracy, K-fold cross-validation is considered superior as it provides a more accurate and reliable estimate of the overall performance of the model. Sentiment analysis results show that Flip app users tend to give negative feedback on speed and security, while they give positive feedback on cost. Therefore, the main recommendation is that the company PT Fliptech Lentera Inspirasi Pertiwi improves the speed and security aspects to increase user satisfaction with the Flip application. Therefore, this customer-centric service will continue to prioritize user satisfaction as its primary goal.

Abstract

Abstrak— Pada penelitian ini akan membahas tentang pengembangan generator soal otomatis untuk materi biologi pada jenjang SMA. Dalam pengembangan generator soal, tentunya telah banyak sekali contoh situs generator soal yang dapat ditemui di internet, akan tetapi hampir keseluruhan generator soal yang dapat ditemui di internet, mengharuskan pengguna untuk menggunakan bahasa inggris dan situs hanya bisa menghasilkan pertanyaan berupa pertanyaan singkat atau factoid, sehingga penelitian ini bertujuan untuk melakukan pengembangan generator soal berbahasa Indonesia dengan tipe pertanyaan non-factoid menggunakan pendekatan template-based. Selain menggunakan pendekatan Template-Based, penelitian ini akan menggunakan algoritma Naïve Bayes untuk proses klasifikasi kalimat dengan bantuan GridsearchCV dan pipeline dari TF-IDF Transformers, String-Match untuk proses eliminasi kalimat, dan Chunking Labelling untuk proses tagging kata. Model generator soal yang dikembangkan pada penelitian ini memiliki rata-rata tingkat akurasi sebesar 90% dengan tingkat persentase jumlah pertanyaan yang layak digunakan sekitar 60%, sehingga model generator yang dikembangkan sudah cukup layak digunakan, akan tetapi memerlukan penelitian lebih lanjut agar model generator soal yang dihasilkan dapat memiliki performa yang lebih baik.Kata kunci— automatic question generator, naïve bayes classifier, chunking labelling, template-based, GridsearchCV, biologi, Soal SMA

Abstract

This essay examines the various learning styles that students can choose from, depending on their preferences. In the COVID-19 era, lectures have been discontinued in classrooms all across the world, but the teaching and learning process is still possible through online platforms. There are learning types with unique characteristics that like to work alone or in groups, as well as visual, auditory, tactile, and kinesthetic learning styles. While some students will adjust to the lecturers' teaching approach, it can be challenging for lecturers to accommodate each student's unique learning preferences. In order to accommodate various student learning styles, lecturers must create their instructional materials in this manner. This article's goals are to: 1) describe and classify the idea of learning styles; 2) emphasize the significance of determining the research participants' preferred learning styles; and 3) emphasize that if a lecturer's teaching style reflects the preferences of the student's preferred learning style, the student's learning outcomes will be enhanced. In this study, a survey, a mix of quantitative and qualitative approaches, as well as questionnaires, are used to gather data on the four preferred learning styles. As a consequence, the majority of participants favored the kinesthetic learning strategy in both solo and group work.

Abstract

Pegadaian. PT. Pegadaian's form of transformation is the launch of Pegadaian Digital application. The application aims to facilitate the community and improve the service of products owned by PT. Pegadaian. Based on the monitoring as of 20 October 2022, the Pegadaian Digital application received 3.5 points on a scale of 5. This score is low because it contains many negative reviews. Therefore, it is necessary to analyse the review section of the application to increase the score. The method that can be used to analyse it is aspect-based sentiment analysis. Aspects are those that relate to the experience felt by users, namely aspects of learnability, efficiency, errors, and satisfaction. Sentiment analysis requires an optimal algorithm, one of which is Naïve Bayes. This algorithm was chosen because it is known as a simple but efficient algorithm when processing large amounts of data. This research uses two test scenarios, the first scenario using different ratios and base parameters and the second scenario using the addition of smoothing parameters. The result of this research is that the model with the ratio of 80:20 and the addition of smoothing is the best model for sentiment analysis because it produces the best performance value, with an accuracy value of 92%, precision of 80%, recall of 70% and f1-score of 73%.
