Abstract

Library is one of the most important pillars to improve the quality of Indonesia’s education. Due to its importance for the next generation, the government tries to increase the establishment of schools and libraries so that the young generation can compete with people from another countries. However, the increasing number of libraries did not mean that the library service quality will become better. Many library systems in Indonesia still have not kept up with technology and still using the manual system, hence the management process and services are not effective. Because of that, this research is created for the purpose of producing a design for a library management application. The methods used in this research is split into multiple steps which is system planning, class diagram planning, MySQL database planning, and GUI planning. The following processes will produce a library management desktop application that is integrated to a database. With this application, processing, documenting, and deliverance of data can be done in more effective and efficient way.

Abstract

Most trainer module equipped a system error simulator (Fault Simulator), to activate the fault simulator the instructor must press a button that will bring up a certain type of fault that the trainer wants to simulate, then students will analyze the source of the error and fix it. The weakness of this trainer is that teachers must press a button on the trainer when they want to change the fault simulator in front of students so that participants will know which type of fault simulator is being run without troubleshooting. If this happens, the teaching objectives are not achieved so that the teaching process using this trainer becomes less effective. To overcome this problem, a remote-control prototype for trainers was designed consisting of an infrared (IR) based transmitter and receiver. To facilitate integration of the fault simulator module, the IR Transmitter and IR Receiver will communicate serially. From the tests carried out, it can be concluded that the designed remote-control prototype for trainers is functioning properly. IR transmitter and IR receiver can communicate serially using infrared media. This remote-control prototype has an optimal distance in the range of 0-5 m.

Abstract

The rapid growth in the number of vehicles has intensified challenges in parking management, leading to traffic congestion and wasted time for drivers searching for available spots. Conventional parking systems, which often rely on manual processes, are inefficient and contribute to these problems. This research addresses these issues by designing and developing an Internet of Things (IoT) based smart parking system to provide real-time monitoring of parking availability. The system utilizes an ESP32 microcontroller, chosen for its integrated Wi-Fi and processing capabilities, as the core processing unit. For vehicle and user management, an RFID-RC522 sensor is used for vehicle entry authentication , while an HC-SR04 ultrasonic sensor detects vehicles at the exit. The backend architecture employs a multi-layered approach, using MQTT as the communication protocol with HiveMQ as the broker. System logic and data flows are managed using Node-RED, which communicates with a Flask server to interact with the database. The user interface is a mobile application developed using Android Studio. This application requires user authentication via a login page and provides a real-time dashboard that visually displays the status of parking slots—green for available and red for occupied. The successful implementation of this prototype demonstrates a functional end-to-end solution that effectively integrates hardware and software to create a more efficient and user-friendly parking management system.

Abstract

This paper presents the design of an Internet of Things (IoT)-based organic waste processing device to produce methane gas and compost. The system uses a large sealed plastic container fitted with a biogas nanometer gauge on the lid and an ESP32 microcontroller for data acquisition. A capacitive soil moisture sensor measures the moisture of decomposed organic material, while an MQ-4 gas sensor monitors methane concentration inside a separate 5-liter plastic storage tank. Organic waste is fermented naturally, and gas is transferred manually through establishing valves while the pressure reaches a described threshold. All sensor information are dispatched to the Blynk cellular software for real-time tracking and visualization. This low-price answer gives a realistic technique to changing family natural waste into renewable power and natural fertilizer.

Abstract

Internet users currently face significant risks from malicious URLs that facilitate phishing attacks, malware distribution, and data theft. Traditional blacklisting methods have become ineffective against evolving cyberattack techniques. This study proposes a Random Forest classification approach for more accurate malicious URL detection, focusing on critical URL features including URL length, presence of special keywords, subdomain structure, and special character usage. these features train the Random Forest model to distinguish between safe and malicious URLs. We evaluate model effectiveness using accuracy, precision, and recall metrics. This research aims to develop a Random Forest-based malicious URL detection system that is more accurate and adaptive than conventional methods. The study examines both the advantages and limitations of this approach, along with its potential as a reliable detection solution for dynamic digital environments. Evaluation results demonstrate an overall accuracy of 94%, weighted average F1-score of 0.94, and macro average F1-score of 0.94.
