Abstract

Machine learning techniques are widely used in various fields and data is needed to train models. However, the distribution of classes in most real-world datasets turns out to be not always balanced, and can be very imbalanced. If the data is imbalanced, the performance of the classifier is highly dependent on the majority class, causing problems in determining performance. One technique that can be applied to balance the data is the Synthetic Minority Oversampling Technique (SMOTE). SMOTE is applied to credit scoring using the German Credit Data (GCD) dataset, and then classified using four classification methods, namely: random forest, K-Nearest Neighbor (KNN), Support Vector Machine (SVM), and Multilayer Perceptron (MLP). The performance measure of implementing SMOTE in each classifier method is measured using: recall, precision, F1-Score, and AUC. Accuracy values are also measured to see if the accuracy is suitable for calculating performance on imbalanced datasets. Based on performance measures: recall, precision, F1-Score, and AUC, then applying SMOTE to the dataset and then classifying it using four methods shows an increase in performance. The highest performance measure: recall = 82.00% with the random forest method, precision = 75.35 with the MLP method, F1-Score = 76.93% with the MLP method, and AUC = 0.832 with the random forest method. The accuracy value after SMOTE slightly decreased in the random forest, KNN, and SVM methods, while with MLP the accuracy value increased slightly. The contribution of this research is to show the need for imbalanced data handling to improve the performance of classifier algorithms, especially for credit rating datasets.

Abstract

In this study the topic raised was about stroke. Based on the statistical results of the Indonesian Health Service Research Agency (2018), stroke is the disease in the first order in Indonesia. Previous studies have carried out stroke research including research that took data from patients at Abdul Wahab Sjahranie Hospital. The model used is the Machine Learning Decision Tree, with an accuracy of 87.5%. For better accuracy, this study predicts stroke using two algorithms, namely support vector machine (SVM) and logistic regression (LR). In the stroke data found there were 10 attributes and 1 output, which consisted of gender, age, hypertension, heart_disease, ever_married, work_type, Residence_type, avg_glucose_level, bmi, smoking_status, and stroke(output). This study uses the SVM+SMOTE model with a confusion matrix and K-Fold and uses 4981 rows and 11 columns. Based on the research results, the support vector machine algorithm is better than the logistic regression (LR) algorithm in predicting datasets using the oversampling and cross-validation methods. Testing the SVM + SMOTE model using the confusion matrix and the K-Fold method produces much better accuracy in the distribution of stroke data accurately. The results show that the Support Vector Machine classification algorithm can work effectively with perfect accuracy of 95.3% at the 10K-Fold Validation level.

Abstract

Communication and information technology in the world of education is an effort made in creating a different teaching-learning atmosphere so that students can develop their potential. E-Learning is a learning process that utilizes computer technology, computer networks, and the Internet in the process of disseminating knowledge, thus enabling students to learn via computers anywhere without having to physically go to class/lectures. Atma Jaya Makassar University already has an E-Learning system but several obstacles occur starting from a less interactive display, limited functions, no integration with the academic system, and the unavailability of mobile-based E-Learning. Previously, e-learning used a claroline base which had problems in terms of appearance and functionality. This research uses the SDLC (Software Development Life Cycle) method in developing e-learning software. The waterfall method is a work method that emphasizes sequential and systematic phases. This method starts from identifying the problems that occur, the design, implementation, testing and verification stages. Moodle-based E-Learning products offer to enter the "digital classroom" to access learning materials with a more attractive appearance and easier access with the mobile application version. The advantages of Moodle include being able to create learning materials, quizzes, and online discussion forums in an E-Learning package. Therefore, this study aims to improve the quality of learning will develop a moodle-based E-Learning system at Atma Jaya University Makassar.

Abstract

Divorce is the breaking of a husband and wife relationship from a marriage. When a couple does not want to continue their marriage relationship, one of the factors causing divorce is that the husband and wife do not carry out their duties properly. Divorce cases also occur in the city of Pekanbaru and have increased from 2020 to 2022. In connection with this problem, researchers conducted research with the aim of classifying districts in Pekanbaru that have the most divorces. The method used in this study is K-Medoids Clustering, because this method can divide a dataset into several groups. The advantage of this method is that it can overcome the weaknesses of the K-Means algorithm which are sensitive to outliers. The tests used in this study use the RapidMiner tools and the Davies Bouldin Index to ensure cluster accuracy. Attributes used in this research are region/regency, age difference between spouses, plaintiff's and defendant's education, and reasons for divorce. The results of this study can be used as information for the government to reduce the divorce rate in the city of Pekanbaru so that appropriate programs can be developed for each sub-district in overcoming the divorce rate in Pekanbaru. From testing using the K-Medoids algorithm, the cluster results obtained showed that the highest divorce rate was in cluster 1 with 565 items, while cluster 2 had 395 items and cluster 3 had 288 items. The results of the study show that the use of 3 clusters is the best cluster with a DBI value of 0.884.
