Abstract

In the current digital era, individual abilities are needed to be more creative and innovative in various fields, so that vocational students must better prepare their competencies. In this case the competence is related to the major they choose. On average, students take the wrong major about 35%, follow friends around 50%, for students who really choose the right major 15%. For this, the MABAC and MOORA decision support system methods are needed in terms of determining majors according to student interests and talents. System development uses the Waterfall method. The purpose of this study is to design a decision support system that can be used for selecting majors according to student interests by utilizing the results of a comparison of the MABAC and MOORA methods. The results of this study illustrate the MOORA calculation for major selection, so prospective students get the decision to choose the Multimedia major because it has the highest score. From the MABAC calculations for the selection of majors, prospective students get the decision to choose the Accounting major because it has the highest score. The comparison of the mabac and moora methods is where mabac has the highest decision outcome value compared to the decision outcome value of the moora method so that the mabac method is used to assist decision making in selecting majors according to interests.

Abstract

 Business analytics plays a crucial role in optimizing telecommunication network performance. This research focuses on using data mining methodologies, specifically the Knowledge Discovery Database (KDD) approach, combined with machine learning algorithms, to predict and enhance 4G signal quality for a mobile operator in Indonesia. The study leverages real-time data from a new site project of an Indonesian telecom operator. Employing SQL ClickHouse for data processing, Python for machine learning, and Tableau for visualization, the research develops a comprehensive data analysis model using hidden Markov models (HMM). The selection of this topic stems from the increasing demand for reliable and high-quality mobile networks, which necessitates advanced analytical techniques to monitor and improve network performance. By implementing HMM, the research aims to provide accurate predictions and actionable insights into signal quality improvements. Preliminary results demonstrate the model's effectiveness in identifying key performance indicators such as accuracy, precision, and recall, as well as trends in network signal quality. The model achieved an accuracy of 93,06%, precision of 96,97%, recall of 95,52%, and F1-score of 96,24%. This study highlights the significant potential of integrating business analytics and machine learning in the telecommunications sector, offering valuable contributions to the industry by improving service quality and operational efficiency.   Keywords—Business Analytics, Network Optimization, Hidden Markov Model, Data Mining, Signal Quality Prediction.

Abstract

Education is very important for everyone, not only for acquiring knowledge but also for improving quality of life and well-being. An Intelligent Tutoring System (ITS) is a computer system that can provide personalized and adaptive learning assistance and support to students. This system is designed to offer effective guidance to students based on their individual abilities and learning styles. ITS utilizes artificial intelligence (AI) technology to understand students' abilities and provide guidance tailored to their needs. Recently, there have been methods to predict learning styles, such as through questionnaires on the EducationPlanner website, but these determinations are often too general. This study aimed to predict the learning styles used by specific students for specific subjects. Researchers conducted this study at XYZ University to determine the learning styles of certain students or groups. With this information, instructional materials and methods can be uniquely designed to cater to the needs of these groups. Based on the evaluation results, the study found that the Logistic Regression model was the best, with a precision of 0.5653 and a hamming loss value of 0.3468. This research demonstrates that information from six selected subjects (English, Religion, Civics, Arts, Physics, and Geography) can be used to determine students' learning styles.

Abstract

This paper aims to observe the adoption of test automation in Indonesia and examine the determining factors that influence the use of this technology in organizations. The study focuses on five critical factors: technology acceptance model, task-technology fit, managerial support (MS), individual performance, and organizational performance. A survey of 109 QA community members was conducted to collect data, and partial least squares structural equation modeling was used for data processing. Based on the study, Selenium is the top test automation framework used for organizations in Indonesia, followed by Appium and Postman. The result showed that out of twelve (12) examined relationships, nine (9) of them were accepted. This data indicates the strong influence of task technology fit (TTF), computer self-efficacy (CSE), perceived ease of use, perceived usefulness, and MS towards behavioral intention and actual use of test automation. Additionally, the actual use of test automation was found to have a positive impact on individual and organizational performance. The study contributes valuable insights for decision-makers by identifying critical factors influencing automation adoption and offers a replicable methodology for evaluating similar technologies.
