Abstract

In the era of globalization driven by the rapid development of information technology, the adoption of technology in various sectors, including education, has become very urgent. Information technology not only supports the learning process but also optimizes administrative aspects, such as the selection of prospective new students. Manual selection is often slow, error-prone, and non-transparent. Therefore, implementing technology-based systems becomes relevant. Benteng Betawi Middle School is committed to implementing a modern, efficient and transparent selection system using the website-based Simple Additive Weighting (SAW) algorithm. The SAW algorithm, as a simple and effective multi-criteria decision making method, is expected to speed up data processing, increase the accuracy and transparency of selection, and identify the best prospective students. This research aims to design and implement a website-based student selection system using the SAW algorithm at Benteng Betawi Middle School. The steps taken include needs analysis, design, implementation and system evaluation. It is hoped that this system can increase the efficiency, transparency and objectivity of the selection process at Benteng Betawi Middle School and become a reference for other schools that wish to adopt similar technology.

Abstract

Optimal healthcare services in hospitals highly depend on a well-organized doctor scheduling system. At Brawijaya Mother and Child Hospital, the scheduling process is still carried out manually, making it prone to errors, delays, and inefficiencies in workflow. This study aims to design and implement a web-based doctor scheduling information system by applying the First Come First Serve (FCFS) method as the basis for queue scheduling. FCFS is chosen for its fair and straightforward approach in determining the order of service based on registration time, without any specific prioritization. The system development follows the waterfall methodology, which includes stages of requirement analysis, system design, implementation, testing, and maintenance. Technologies used in this system include PHP programming language, MySQL database, and supporting frameworks. The system features include doctor data management, practice scheduling, and online patient registration, accessible by both patients and hospital administrators through a user-friendly interface. The implementation results show that the system is capable of managing doctor schedules in a more structured manner, reducing schedule conflicts, and increasing efficiency in patient service processes. The presence of this information system accelerates administrative processes, improves transparency and accuracy, and supports the quality of services while enhancing patient satisfaction. This research is expected to provide a digital solution for hospitals in managing doctor schedules and to serve as a foundation for developing similar information systems in the future.

Abstract

Kost Pinangga is a boarding house that provides temporary housing consisting of several rooms that are occupied by STAN students. In addition, Kost Pinangga has one of the internet or wifi facilities that can be used by residents of Pinangga Boarding House. However, the use of the internet simultaneously results in an undivided network on all users, so bandwidth management is needed. For this reason, bandwidth management is needed to manage every data that passes, so that the bandwidth division becomes evenly distributed using the PCQ (Peer Connection Queue) method. In this study, a comparative analysis was carried out between using the PCQ (Peer Connection Queue) method to optimize internet bandwidth, analyzing QoS (Quality of Service) bandwidth management in terms of throughput, delay, jitter and packet loss. The results of this research show that network quality using the PCQ (Peer Connection Queue) method is more optimal, because the bandwidth division will be divided evenly in each user.

Abstract

Student academic performance is one of the important indicators of success in the learning process. Therefore, a method is needed that can analyze and accurately predict students' academic performance. This study aims to analyze and predict students' academic performance using the Random Forest algorithm. The dataset used consists of 649 student records with 33 attributes covering student characteristics, family background, social activities, and academic grades. The students’ final grade (G3) is used as the target variable in the classification process.The research stages include data exploration, data preprocessing, splitting the data into training and testing sets, building the Random Forest model, and evaluating the model. The results show that the Random Forest model is able to achieve an accuracy rate of 92.31%. Testing using a confusion matrix indicates that the model has a relatively low prediction error rate. In addition, testing using the cross-validation method produces an average accuracy of 91.21%, indicating that the model has good stability. Feature importance analysis shows that previous academic grades, namely G2 and G1, are the most influential factors affecting students' academic performance. The results of this study indicate that the Random Forest algorithm can be effectively used to predict students' academic performance and can assist educational institutions in data-driven decision-making.
