Abstract

In today's digital era, online games such as Minecraft are rapidly growing as part of the entertainment industry. Arknesia Entertainment Network developed an independent Minecraft server called Reforged World to improve users' gaming experience. However, there are challenges in integrating server data efficiently. This research aims to develop a RESTful API that integrates with the backend using Express.js, the website frontend using Next.js, and the mobile application using Expo. This RESTful API allows real-time management of server status data, player information, and game statistics. The results show that the RESTful API is able to improve service quality and provide a better user experience. Full documentation is provided to make it easier for other developers to implement and further develop the API.

Abstract

The development of information technology has encouraged the utilisation of expert systems in various fields, including health. An expert system is a computer system designed to mimic the ability of an expert to make decisions. This article discusses the design and implementation of an expert system to diagnose diseases based on the forward chaining method. This method works by tracing the facts provided by the user to the right conclusion. The purpose of this research is to assist the community in making an initial diagnosis of common diseases. The implementation results show that the system is able to provide accurate diagnosis results based on the symptoms entered by the user.

Abstract

The advancement of digital technology has driven transformation in the delivery of information services in higher education institutions. One innovation that is being increasingly adopted is the use of Natural Language Processing (NLP)-based chatbots in academic service systems. This chatbot enables natural conversation-based interactions between users and systems, facilitating students in accessing information quickly and efficiently. This paper discusses the basic concepts, benefits, system architecture, and challenges faced in integrating NLP-based chatbots into academic service systems. By adopting this approach, universities can enhance service quality, reduce administrative burdens, and promote the digitalization of academic processes in a comprehensive manner.

Abstract

Scheduling problems in school environments often present significant challenges due to the involvement of numerous variables and constraints, such as teacher availability, classroom allocation, and balanced subject distribution. Manual scheduling tends to be time-consuming and prone to errors, necessitating a more efficient and adaptive solution. This study aims to design and implement an automatic scheduling system using a Genetic Algorithm. This algorithm is chosen for its capability to solve optimization problems with complex solution spaces. The development process involves representing chromosomes as combinations of schedule elements, selecting based on conflict levels, and applying genetic operators such as crossover and mutation to generate optimal solutions. Test results show that the system is capable of producing high-quality schedules with minimal conflicts and efficient computation time. This approach significantly enhances the speed, accuracy, and flexibility of school scheduling systems

Abstract

In the rapidly evolving digital era, the need for accurate and personalized recommendation systems is increasingly important, particularly in digital libraries and online bookstores. This study aims to develop a book recommendation system using a collaborative filtering approach, which leverages user interaction data to suggest books that align with individual preferences. The system utilizes a user-based collaborative filtering method by calculating similarities between users based on their historical book ratings. The dataset used in this research is a simulated, anonymized dataset from a school library. Testing results indicate that the system is capable of delivering relevant recommendations with good accuracy, demonstrated by a low Mean Absolute Error (MAE) score and positive user feedback. This system allows users to discover books aligned with their interests more efficiently, thereby enhancing the overall reading experience.
Analisis Performa Algoritma CNN dalam Klasifikasi Citra Medis Berbasis Deep Learning Sari, Nely Puspita

Abstract

The advancement of artificial intelligence technologies, particularly in the field of deep learning, has driven the application of Convolutional Neural Network (CNN) algorithms in various domains, including medical image classification. This study aims to analyze the performance of CNN in classifying medical images associated with different diseases using a standard CNN architecture. The dataset utilized consists of labeled X-ray and MRI images based on medical diagnoses. Evaluation metrics such as accuracy, precision, recall, and F1-score were used to assess how effectively the model recognizes complex visual patterns. The results demonstrate that CNN achieves high accuracy in identifying objects within medical images, with an average F1-score exceeding 90% on selected datasets. These findings suggest that CNN has significant potential to support automated and efficient medical diagnosis, although further clinical validation is necessary for real-world implementation.

Abstract

Public Wi-Fi networks are highly vulnerable to the misuse of Internet access, particularly for accessing websites containing online gambling, pornographic content, and illegal online lending services. Similar issues were identified in the public Wi-Fi network of Bukit Peninjauan II Village, which lacked an effective website filtering mechanism. This study aims to implement a network security system using MikroTik firewall integrated with DNS Static based on Regular Expressions (Regex), TLS Host Filtering, and the blocking of DNS over HTTPS (DoH) and QUIC protocols. This study used the Network Development Life Cycle (NDLC) methodology, which consists of the analysis, design, implementation, testing, and evaluation phases. The proposed system was implemented on the public Wi-Fi network of Bukit Peninjauan II Village by configuring firewall rules to filter website access based on predefined domain patterns. The results demonstrate that the implemented Firewall Filter, DNS Static Regex, TLS Host Filtering, DNS over HTTPS (DoH) blocking, and QUIC blocking functioned as intended. The system successfully restricted access to websites related to online gambling, pornographic content, and illegal online lending services without affecting access to authorized websites. Furthermore, blocking DoH and QUIC effectively prevented users from bypassing the implemented filtering mechanism. In conclusion, the proposed network security system effectively enhances Internet access control and provides a safer, more secure, and better-managed public Wi-Fi environment for the community of Bukit Peninjauan II Village.

Abstract

The rapid development of information technology has encouraged students to be more active in using digital devices and the internet for learning activities and daily communication. However, the use of these technological devices is not accompanied by adequate awareness regarding cybersecurity. This makes students vulnerable subjects to various digital threats such as phishing, data theft, account misuse, malware, and cyberbullying. This education aims to provide students at SMA Panca Budi with an understanding of the importance of cybersecurity and how to protect personal data. Awareness of personal data protection will provide security and protection for personal data, which is now increasingly stored digitally. As teenagers with high curiosity, it is important to provide education and practice in digital security by implementing stronger password creation, enabling two-factor authentication, recognizing indications of phishing attacks, and avoiding the prevalence of cyberbullying. It is hoped that this will increase students' cyber awareness in supporting a digital security culture within the school environment.
