Abstract

MOBA is a popular genre that requires teamwork to achieve victory. A close and tight match is what make MOBA fun to play and increase its user satisfaction, but some factor may ruin the matchmaking and create unbalanced match between the two team. Those problems factors are high latency, players with bad attitude, and players doing unfamiliar role. We use DOTA 2 as our case study. Then we compare the DOTA 2 matchmaking system in other sector to make comparison. Lastly, we discuss about solution to solve MOBA matchmaking problem such as displaying live information about online players, players searching for games, servers online and ETA for gaming to start. In addition, we proposed new variable to be considered in the matchmaking system, which are Preferences Role, player’s chosen preferences role will be considered while the system set up the game to minimize the number of unbalanced games in MOBA.

Abstract

This research aims to develop and design an Intelligent Tutoring System (ITS) model to improve the efficiency and adaptability of the learning process using technology based on student personalization. This study employs a systematic literature review method, as well as bibliometric analysis and visualization using the VOSviewer application. We collected data from several well-known article databases. The results showed an intelligent tutoring system model to be connected to five components and 22 sub-components. These components consist of a student model, a pedagogical model, an interface model, a tutor model, and a domain model. Thus, these components and sub-components produce a responsive student model that can be used to develop a learning system within the Indonesian National Armed Forces. The responsive student model not only assesses students' visual, auditory, or kinesthetic learning styles but also gauges their emotions or concentration levels during the learning process. This development not only increases learning effectiveness but also improves student learning experiences and supports adaptive and sustainable academic growth.

Abstract

The research aims to provide Data Monetization (DM) services for an Indonesian utility company as a pilot to generate additional revenue beyond the primary operation. The service is built using an iterative development lifecycle framework and evaluated based on five Quality Goals (QGs), including application and security testing activities. The framework includes methods for processing and modeling electricity usage data, testing application quality, checking infrastructure quality, and ensuring access security for front-end and back-end applications using the Open Web Application Security Project (OWASP). For data modeling, Support Vector Regression (SVR) is used, and it outperforms Polynomial Regression (PR) and Multi-Layer Perception (MLP) Neural Networks. Furthermore, QG shows strong performance with an Relative Root Mean Squared Error (RRMSE) value < 10%, high forecasting ability with Mean Average Probability Error (MAPE) < 10%, and a near-zero average error rate (Mean Squared Error (MSE)) square using minimal data from four months. The services go through functional and integration test to ensure product quality and application performance, which results in a minimum of 95% service response in throughput, 0.128 seconds for processing 2,000 requests, stability at 300–500 in one second per hour, and 7–21 seconds during peak hours. Additionally, the service passes nine penetration tests and ten vulnerability assessments using the OWASP top 10:2021 category. Based on the comprehensive testing and evaluation results, both the application and the service are considered ready and secured for deployment.

Abstract

Product innovation and service improvement have become essential or crucial for organisations, including public service organisations. The Indonesia Immigration Directorate released the m-passport application to enhance its quality of service. The m-passport application is considered good as it has been downloaded over a million times. Like immigration officers, this application seems to be at the forefront, reflecting an increasingly better service. However, there was still a need for significant improvement in the application. Improvements can be made to the application by considering user feedback or reviews. Reviews provided by users, approximately 12K, will serve as input for improving or enhancing the application. This was made possible as users interacti directly with the application. The most common issues are one-time password or OTP verification code with a probability value of 0.044, errors when logging in with a probability value of 0.283, and slow response applications with a probability value of 0.125.

Abstract

Saat ini, perguruan tinggi sebagai motor pencerdas bangsa dituntut untuk lebih melek dengan perkembangan informasi teknologi, perkembangan peralatan komunikasi dan jaringan internet berkecepatan tinggi saat ini. Pendidikan di perguruan tinggi dituntut untuk mampu mengarahkan mahasiswa untuk lebih mandiri dan mampu menggunakan teknologi pembelajaran elearning, yang pada akhirnya akan mempengaruhi kemampuan mahasiswa ketika bekerja dan terjun ke dalam masyarakat. Pengembangan sebuah Elearning sebagai sebuah software aplikasi dapat dilakukan dengan berbagai macam metodologi atau framework dan salah satunya adalah framework Learning Technology System Architecture (LTSA) yang merupakan standar 1484.1-2013 dari Institute of Electrical and Electronics Engineers (IEEE) untuk teknologi pembelajaran. Standar IEEE 1484.1-2013 dikembangkan oleh IEEE Learning Technology Standards Committee (LTSC) yang merupakan bagian dari IEEE Computer Society dan diterbitkan pada tahun 2013. Pengembangan elearning dengan framework LTSA akan menerapkan atau memetakan komponen proses dan penyimpanan data pada LTSA dengan menggunakan metode pengembangan berorientasi obyek yang disebut Unified Modeling Language (UML). Penerapan framework LTSA dalam mengembangkan elearning dibatasi pada penggunaan beberapa diagram pada UML seperti sequence diagram, use case diagram, class diagram, package diagram, activity diagram dan component diagram. Penggunaan UML pada pengembangan elearning dengan menggunakan framework LTSA diharapkan dapat memberikan pencerahan bagaimana membangun sebuah elearning dengan paradigma berorientasi obyek. Beberapa contoh penerapan diagram UML dalam pengembangan elearning diberikan sebagai gambaran bagaimana sebuah elearning dikembangkan dengan framework LTSA. Pada akhirnya perguruan tinggi yang mengabaikan teknologi dalam proses pembelajaran akan tidak menarik dan ditinggalkan oleh masyarakat yang semakin peduli dan menikmati teknologi sebagai bagian dari kehidupan manusia.

Abstract

Despite having many advances in video game control such as voice or gesture control, most video game console manufacturers still use a joystick as the main control for their console. Currently, the problem with video game manufacturers is that instead of using the joystick as the point of user interface design, they instead used a design from another device such as a computer or tv. The research will compare Xbox One and Steam OS user interface by using KLM-GOMS Model. Based on the calculation it is concluded that the overall Xbox One has a more efficient design compared to Steam.
