Abstract

This research aims to design Internet of Things (IoT) based medical devices that can monitor body temperature, heart rate and oxygen saturation. The problem faced is the lack of real-time health monitoring tools that are integrated with digital systems, especially during the pandemic. As a solution, this tool utilizes the MLX90614 sensor to measure body temperature, the MAX30100 sensor for heart rate and oxygen saturation, and the ESP8266 microcontroller to connect the device to a Wi-Fi network. The method used is system development using the Waterfall model, starting from needs analysis, design, implementation, to testing. A threshold algorithm is applied to detect abnormal values in sensor data, which is then sent to the server and displayed via a web interface. Test results show that this tool can monitor health conditions accurately and in real-time. Data on body temperature, heart rate and oxygen saturation are stored in a database and displayed via the web with a fast response. This tool is expected to help users in monitoring health more efficiently and easily to use.

Abstract

Monitoring radon gas concentrations in various environments, such as residential areas, buildings, caves, and mining sites, is crucial to minimizing health risks associated with radon exposure exceeding the 100 Bq/m³ threshold set by the World Health Organization (WHO). Additionally, anomalies in radon concentration in fault zones are often considered precursors to seismic activity. Therefore, this study develops a real-time Internet of Things (IoT)-based radon gas monitoring system using a cost-effective approach. The system utilizes a ZnS(Ag)-based scintillation detector combined with a Photo Multiplier Tube (PMT) model H10492-001 (Hamamatsu, Japan). Calibration results at the Geological Resource Research Center – BRIN Bandung indicate that the detector has an average efficiency of 79.8%. The cloud-based monitoring system is developed using PHP 8.0 and MySQL 10.5, with performance evaluation conducted through an API using the GET method via the cURL application. Testing with various intervals and iterations shows that the system achieves 99% data reception and recording efficiency compared to the data sent by the test device. Performance testing using Chrome DevTools indicates a response time ranging from 32–140 ms, demonstrating that the system responds quickly and efficiently handles user requests. The system includes an early warning mechanism that activates when sensor data exceeds a predefined threshold, featuring a red indicator on the dashboard, an alarm sound, and automatic notifications to a Telegram bot. Responsiveness testing confirms that the dashboard display adapts optimally to various screen sizes, ensuring accessibility across multiple devices. From a cybersecurity perspective, the system implements HTTPS protocols and has received an A rating from www.ssllabs.com. It also employs BCrypt encryption with a 184-bit hash length for password protection.

Abstract

The Songket PaSH website is a Palembang-based MSME (Micro, Small, and Medium Enterprises) platform that offers a variety of traditional handcrafted products, such as songket fabric, jumputan, and Palembang batik. Since its implementation, the website administrators have not conducted an in-depth analysis of user experience and interaction quality—whether from users who complete transactions or those who only browse. To maintain sustainable business-to-business (B2B) relationships and prevent communication breakdowns, an evaluation of the Songket PaSH website’s quality is necessary. This study aims to evaluate the website’s quality using a descriptive quantitative method with the Webqual approach. The Webqual method includes three main variables: Usability, Information Quality, and Service Interaction Quality, which collectively provide a comprehensive overview of a website’s quality. The results indicate that all three aspects fall into the "Good" category, with an overall average score of 73.2% based on the Likert scale interpretation. Nevertheless, several indicators still require improvement according to the evaluation priorities identified in the study.

Abstract

Along with the development of Internet of Things (IoT) technology, monitoring the condition of bridge infrastructure can be done in real-time to improve the safety and durability of construction. This study aims to design and implement an IoT-based bridge vibration monitoring system using MPU6050 and SW-420 sensors connected to ESP32. This system is designed to detect vibration changes that can indicate potential damage to the bridge structure. The research method used is an experimental and quantitative method, by testing the tool on iron and concrete bridges. Data obtained from the sensor will be sent to a local MySQL-based server and displayed in graphical form via a PHP-based web interface. The test results show that the system can detect vibration variations according to changes in vehicle load, where heavier loads produce more significant fluctuations in the acceleration values of the X, Y, and Z axes. With this system, it is expected that bridge condition monitoring can be carried out more efficiently and accurately, so that managers can take preventive measures before more severe damage occurs. The results of this study can be a reference in the development of further bridge monitoring systems and the application of IoT technology in the infrastructure sector.

Abstract

Digital security has become a major challenge in the metaverse, an interactive virtual space that integrates augmented reality and virtual reality. This study develops a machine learning-based Network Intrusion Detection System (NIDS) to enhance security reliability within the metaverse. K-Means and Apriori algorithms are applied to optimize rules in the Snort IDS, enabling more accurate detection of Distributed Denial of Service (DDoS) and Malware Command and Control (CNC) attacks. The results show that rule optimization using machine learning increases detection accuracy for DDoS attacks from 60% to 75% and for CNC attacks from 35% to 40%. Furthermore, this approach successfully reduces the false positive rate. The implementation of the optimized NIDS provides a significant contribution to securing activities in the metaverse, ensuring a safer and more reliable virtual environment.
