Abstract

The Internet of Things (IoT) is a number of devices that can collect and transmit data between sensors without the need for human assistance. However, the security of IoT can be threatened due to its nature that can be accessed from anywhere and at any time. Security gaps have the possibility of being difficult to detect, because they have a variety of patterns. Therefore, a secure model for sending data between sensors is needed. Blockchain is a technology that can answer the three necessary security requirements, namely availability, confidentiality, and integrity. In this research, we try to build an IoT security simulation using blockchain technology, where the security system uses the publicblockchain pattern. The method used in this research is a publicblockchain model that allows users to control applications connected to the emulator pin through smart contracts. This research uses the Ethereum network which is included in the testing network that can be used without any transaction fees that need to be paid. With this research, it is hoped that it can provide solutions to security problems and challenges faced in IoT networks.

Abstract

Healthy living is the desire of every human being. Maintaining health involves disease prevention and continuous physical and mental care. Health parameters such as heart rate, blood oxygen saturation, and body temperature are important indicators of a person's physical and mental condition. Normal heart rate and oxygen levels are essential for efficient heart function, while body temperature can indicate various health conditions. Currently, health checks are usually carried out by visiting health facilities such as hospitals, health centers, and so on, which are considered less effective because they take a lot of time. Although health check tools such as pulse oximeters and digital thermometers are currently available, these tools can only display health information when used and measurement data cannot be saved to a database for long-term monitoring. Therefore, a health monitoring tool is needed that can be used personally to monitor the user's health periodically. In this study, the author developed a mobile health monitoring application using the Dart programming language and the Flutter framework. This application is integrated with the MAX30102 oximeter sensor and the MLX90614 temperature sensor via the Esp32 microcontroller with the Bluetooth Low Energy (BLE) communication protocol. This system allows users to perform personal health checks without disturbing their daily routines, measurement data is displayed in real-time on the application and stored on the server for long-term monitoring. This study successfully developed an IoT mobile application with Esp32 to monitor heart rate, blood oxygen saturation, and body temperature. The blackbox test showed 100% success with a measurement accuracy value of 95.55% for heart rate, 99.01% for oxygen saturation, and 99.269% for body temperature.

Abstract

E-learning has become an essential need in education, especially accelerated by the COVID-19 pandemic. The implementation of online learning systems using Moodle-based Learning Management System (LMS), which requires evaluation to ensure its effectiveness and usability. This study aims to implement the System Usability Scale (SUS) method to measure the level of usability. This evaluation is expected to provide recommendations for improvements to improve the quality of online learning. Based on the existing problems, it explains how to implement the SUS method to measure usability in the e-learning system at UMM. The study was limited to usability evaluation using the SUS method without discussing other aspects such as learning content or other supporting technology infrastructure. The study used the SUS method which involved a questionnaire with 10 questions to assess usability aspects such as learning ability, efficiency, error rate, and user satisfaction. The analysis showed a fairly good level of usability but still needed some technical improvements such as system stability and ease of use. The implementation of the SUS method was effective, providing valuable insights for system improvements to improve the learning experience.
