Abstract

This research aims to answer the need for a security system that is capable of detecting LPG gas leaks in restaurants to avoid potential fire and explosion hazards. The system developed uses an MQ-2 gas sensor controlled by an Arduino Uno R3 microcontroller, capable of detecting the presence of LPG gas and providing early warning to restaurant owners. The main objective of this research is to design and implement an effective and efficient safety system in detecting LPG gas leaks, which can provide warnings quickly and accurately to prevent accidents (explosion and fire). The methodology used in this research includes the hardware and software design stages, as well as system testing in an actual restaurant environment. The hardware consists of the MQ-2 sensor, Arduino Uno R3 microcontroller, buzzer module to provide alarms, I2C LCD to display data received from the MQ-2 gas sensor, and others. Software was developed using the Arduino IDE platform to program the microcontroller to detect and respond to gas leaks. The results of system implementation show that the MQ-2 sensor is able to detect LPG gas leaks quickly and accurately. An alarm sounds as soon as a leak is detected, providing effective early warning to restaurant owners. In addition, this system has also been tested in various conditions to ensure its reliability. The conclusion of this research is that the security system based on the MQ-2 sensor and Arduino Uno R3 microcontroller can function well in detecting LPG gas leaks and providing early warning which is much needed to prevent accidents in restaurants. This system is proven to be efficient, easy to implement, and reliable as an effective security solution. ABSTRAKPenelitian ini bertujuan untuk menjawab kebutuhan akan sistem keamanan yang mampu mendeteksi kebocoran gas LPG di rumah makan guna menghindari potensi bahaya kebakaran dan ledakan.

Abstract

This study aims to develop a Smart Farming Hydroponic system based on IoT (Internet of Things) technology using the NFT (Nutrient Film Technique) for cultivating Shanghai Pakcoy. Utilizing the Arduino UNO R4 WiFi as the main microcontroller, the research integrates TDS and pH sensors to enable real-time monitoring of AB mix nutrient levels and water acidity. All data collected by the system is processed using the Arduino Cloud IoT Remote platform, allowing for remote monitoring and automated control. The study is conducted in Kampung Buah Tilu, Desa Cisaat Padarincang, focusing on optimizing limited land use in rural areas to introduce modern agricultural technology. The system is designed to enhance cultivation efficiency by maintaining nutrient and pH parameters within optimal ranges for plant growth. Additionally, the scope of the research is limited to technical aspects of nutrient management, excluding temperature and humidity control. The findings indicate that the Smart Farming Hydroponic NFT (Nutrient Film Technique) system successfully improves cultivation efficiency, provides real-time data visualization, and ensures optimal conditions for Shanghai Pakcoy growth. This research not only offers an efficient and eco-friendly agricultural solution but also opens up opportunities for developing similar technologies to empower rural communities. Through this innovation, IoT (Internet of Things) technology can be applied to sustainable farming systems to enhance productivity and improve agricultural product quality.

Abstract

Measuring student discipline can be done by recording their attendance. Attendance is crucial evidence of participation in every institutional reporting activity. In education, attendance is used to record who is present in class. However, traditional attendance systems that call students' names one by one face various challenges, such as taking a long time to record data, the potential for damage to attendance records, and lack of accuracy. This research focuses on implementing an online attendance system based on the Internet of Things by utilizing the ESP8266 microcontroller and RFID student card scanner at SMP Negeri 1 Carenang. This system is designed to address the limitations of manual attendance systems that are inefficient and prone to errors. By using the ESP8266 microcontroller as the data processing center, the RFID MFRC522 sensor to read student identity cards, and the MySQL database to store attendance data, this system allows real-time monitoring of student attendance through a website accessible to teachers and parents. The implementation of this IoT based online attendance system is expected to improve student discipline and motivation, as well as facilitate teachers in accurately and effectively monitoring student attendance.
