Abstract

The Internet of Things (IoT) has grown rapidly and become an important part of many sectors, from industry to healthcare to households. However, this growth also increases security risks, especially regarding data communication between devices. One promising solution is the implementation of asymmetric cryptography, which offers encryption and decryption mechanisms using public and private key pairs. This article discusses how asymmetric cryptography can be applied in IoT systems to maintain data confidentiality, integrity, and authentication. In addition, implementation challenges such as limited computing power and energy consumption in IoT devices are analysed, as well as solutions that can be applied to overcome them. This study shows that despite technical barriers, the use of asymmetric cryptography remains relevant and effective as a layer of protection in an increasingly complex IoT ecosystem.

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

The academic information system is a system built to facilitate academic administration activities in educational institutions and is carried out online. Academic data processing still uses sheets of paper and archives (manual), causing existing data to be easily lost or damaged and searching for data takes a long time. The purpose of this research is to design a web-based academic information system to support operational activities and make it easier for schools to deliver information by applying Progressive Web Apps (PWA) to make easy access for student teachers when entering applications with mobile web displays on smartphone devices. The testing method used is the black-box testing method, namely the system is executed through trials and checks the functionality of the web application. The results of testing this application students, teachers, principals login to enter the main display. The main menu has student data, teacher data, assessments, assessments, lesson schedules and profile pages. The conclusion of testing the information system is as desired by the school in providing convenience in conveying information and the application can run well and no bugs are found.

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.
