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%.

Abstract

Di Indonesia, seiring dengan pertumbuhan fintetch mengenai P2P lending, juga timbul P2P lending ilegal yang beroperasi tanpa izin dari otoritas berwenang. Diperkirakan terdapat sekitar 400 perusahaan fintech ilegal yang beroperasi di Indonesia. Masalah umum yang dihadapi oleh platform P2P lending adalah ketidakmampuannya mengantisipasi pembayaran yang gagal oleh peminjam. Hal ini disebabkan oleh tingginya suku bunga yang diterapkan dan kurangnya seleksi terhadap peminjam dengan risiko kredit yang tinggi atau rendah. Untuk mengatasi masalah ini, diperlukan pengembangan model sistem Machine Learning yang dapat mengklasifikasikan data peminjam dan terintegrasi dengan informasi dari lembaga keuangan lainnya. Tujuannya adalah untuk menyaring calon peminjam dengan risiko kredit yang tinggi atau rendah. Salah satu model yang digunakan adalah algoritma Naïve Bayes Classifier. Metode ini berdasarkan teorema Bayes dan merupakan algoritma yang memproses klasifikasi sederhana dengan independensi variabel. Penggunaan algoritma Naïve Bayes Classifier diharapkan dapat menciptakan sistem yang membantu platform P2P lending dalam seleksi calon peminjam. Model ini akan memprediksi risiko kredit rendah atau tinggi bagi pengguna atau pelanggan P2P lending. Untuk mencapai performa klasifikasi optimal, dilakukan tuning hyperparameter pada setiap simulasi. Hyperparameter tuning adalah proses mencari nilai terbaik untuk parameter dalam model machine learning guna meningkatkan performa. Pada algoritma GaussianNB, parameter yang dituning adalah var_smoothing. Hasil tuning hyperparameter terbaik ditemukan dengan nilai var_smoothing sebesar 0.009638958856642498, dengan pembagian train_size dan test_size sebesar 70:30. Dengan konfigurasi ini, model mencapai tingkat akurasi sebesar 95%.

Abstract

Indonesia has a dominant tropical climate, which is why it experiences limited temperature variations but diverse rainfall patterns. The variability of rainfall is closely intertwined with the impacts it exerts on various aspects of human life and business activities. Therefore, rainfall information constitutes a crucial aspect in decision-making. However, of course, there is a need for stages and methods to conduct the analysis process. Hence, this study aims to determine the superior method between C4.5 and K-Nearest Neighbors, both of which are algorithms in data mining, for classifying rainfall data. Both algorithms are employed to construct classification models based on relevant attributes. Subsequently, these models are tested and evaluated using various metrics such as Accuracy, Precision, Recall, and F1-Score. In this study, Hyperparameter Tuning is also applied using the RandomizedSearchCV method to obtain optimal parameters that can yield maximum accuracy. The research findings indicate that both algorithms perform well in rainfall classification. When considering the accuracy values obtained with the default parameters of both algorithms, C4.5 exhibits a higher accuracy rate of 81.42%, whereas K-Nearest Neighbors only achieves 78.10%. However, after utilizing the best parameters resulting from the implementation of Hyperparameter Tuning with RandomizedSearchCV, a significant accuracy improvement is observed in K-Nearest Neighbors, which reaches 83.37%. Meanwhile, C4.5's accuracy increases to 82.56%.

Abstract

Efficient management of hospital assets is essential to ensure that operations can run optimally and the quality of health services is good. However, the recording and management of assets in hospitals carried out manually often causes data errors, information mismatches, and also assets are only known by the manager without being explicitly recorded. In overcoming this problem, the researcher aims to develop a hospital asset detection system architecture using an iterative and incremental methodology approach. The stages of this system development include identification of needs and conceptual models, logical architecture design, conceptual architecture design, logical architecture, physical architecture, technology selection, and evaluation. This system utilizes YOLO model reading technology for asset detection and identification, storing detection results into a local database using SQLite3, sending data to a central server via API, and post-processing data by selecting the highest confidence score stored in a MySQL database and then using the data to manage asset management and asset visualization. The implementation of this system successfully reduces manual recording time, improves asset visibility, and optimizes resource usage, thus contributing to the improvement of efficiency and quality of health services.

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

The human handwriting pattern is one of the research areas of pattern recognition; it is very complex. Therefore, research in this field has become quite popular. Moreover, human handwriting pattern recognition is needed for several things, one of them being character recognition. Recognition of Arabic handwriting is complex because everyone has different characteristics in writing and Arabic characters have quite abstract shapes and patterns. From previous research, Convolutional Neural Network (CNN), a deep learning-based algorithm, has a fairly high accuracy value when used for public datasets such as AHDB and private datasets. In this study, private datasets are used with a fairly high level of complexity because the respondents appointed to write Arabic letters come from different age categories. The CNN architecture used in this research is the architecture developed by Yan LeCun known as LeNet-5. The local dataset used was 8400 images, with details of 6720 for training data (each letter has 240 images) and 1680 for testing data (each letter has 60 images). The total respondents who wrote Arabic script were 30 people, and each person wrote each letter ten times. The accuracy obtained is 81% higher than in previous studies. The following study will test a number of additional CNN architectures to increase the accuracy of the results. In addition to accuracy, this study will also calculate the misclassification rate, root mean square error, and mean absolute error.
