Abstract

Fires are one of the most devastating disasters, often resulting in major losses—both materially and in terms of human lives. To help reduce these risks, a fast and accurate fire detection system is essential. This study presents the development of a fire detection system based on the Internet of Things (IoT), which integrates Discord Webhook notifications and an alarm system, powered by Fuzzy Logic. The system uses flame, smoke, and gas sensors to detect potential fire hazards in an area. Sensor data is processed using Fuzzy Logic to assess the level of fire risk more accurately, and the Center of Gravity (COG) method is used for defuzzification. When a dangerous condition is detected, the system automatically triggers an alarm, a flashing light, and a blower as preventive actions. Thanks to the IoT integration, real-time alerts can be sent via Discord Webhook, keeping users informed instantly. This approach addresses the lack of systems capable of delivering immediate fire warnings. The results of this research show that the system can effectively provide early fire detection with high accuracy and rapid notifications. When both the flame and gas sensors detect danger, a warning is sent to the user through Discord, and users can also review past events through the system’s web server history. Overall, this system offers a practical and innovative solution to improving safety and disaster response.

Abstract

A security system is a crucial component in creating a safe and conducive school environment. This research aims to design and build a prototype of an automatic door security system at SMPN 1 Warungkiara. The system integrates a reed switch sensor to detect the door's status, along with RFID and fingerprint technology as access authentication media. Security notifications are sent in real-time via the Discord platform using a NodeMCU ESP8266 microcontroller connected to a Wi-Fi network, especially for suspicious activities outside operational hours. The research method employed is qualitative with a case study approach, while the system development applies the prototyping model. The development stages include requirements communication, quick design, prototype construction, and user evaluation. The test results indicate that the system prototype functions well and effectively. The sensor accurately detects the door's status, the authentication process using RFID and fingerprint operates as designed, and notifications to Discord are sent instantly. The implementation of this system is expected to enhance digital security monitoring, minimize risks, and support the creation of a safer and more comfortable teaching and learning process within the school environment.

Abstract

The advancement of Internet of Things (IoT) technology has driven the development of automation systems that enhance comfort and efficiency across various sectors, including hospitality management. This study aims to design and implement a smart homestay system capable of automatically and manually controlling electrical devices using ESP32 and Arduino Uno microcontrollers. The system is equipped with several sensors, such as BH1750 for light intensity detection, MQ2 for smoke and alcohol detection, as well as physical buttons and smart switches for room services including laundry, cleaning, and Do Not Disturb (DND). An Android application, developed using MIT App Inventor, serves as the user interface and communicates with the ESP32 via a local Wi-Fi network using a Web Server method. Experimental results show that the system effectively responds to both sensor input and user commands, displaying real-time data in the app. The automatic light control feature based on lighting levels, gas detection notifications, and room service buttons functioned as designed. The system also supports two-way control between physical buttons and the mobile application. Quantitatively, response times for LED control averaged less than 1 second, sensor readings were updated every 3 seconds, and service command success rates reached 100% in all test scenarios. Therefore, the smart homestay system offers a simple yet effective solution to improve service and comfort in small-scale accommodations.
