Abstract

This research designs a prototype condensation detection system on Air Handling Unit (AHU) ducting at Juwata Tarakan Airport by utilizing Internet of Things (IoT) technology based on the Blynk platform. Condensation problems in AHU systems often cause water droplets that impact passenger comfort and safety, but there is no effective monitoring system for early detection. This system uses DHT11 and Raindrop sensors integrated with an ESP32 microcontroller, which will send temperature, humidity, and water presence data to the Blynk application in real-time. Test results show that the system is able to detect potential condensation quickly and accurately, and send notifications to technicians in less than two seconds. In addition to improving AHU maintenance efficiency, this system also supports increased security and comfort in the terminal area. This research is expected to be a practical solution for intelligent HVAC system monitoring in public facilities.

Abstract

This research aims to design a prototype of an Internet of Things (IoT)-based temperature and humidity monitoring system. This tool is designed using the Blynk platform implemented in the Air Handling Unit (AHU) at Juwata Tarakan Airport. This system uses ESP32 as a microcontroller, DHT22 sensor, and OLED LCD and the Blynk application as monitoring media. In this research, I used the Research and Development (R&D) method with the stages of problem identification, design, testing, product revision, and conclusion. The test results show that the system can monitor temperature and humidity in real-time, provide automatic notifications when the temperature exceeds the threshold, and facilitate technicians in supervision without having to be physically present on site. This system can be applied not only at airports, but also in commercial buildings and other public facilities that require an efficient temperature and humidity monitoring system

Abstract

The conventional conveyor system at Iskandar Pangkalan Bun Airport has limitations in terms of operational efficiency and safety, particularly related to the lack of an integrated emergency stop indicator. This study aims to design, implement, and evaluate a conveyor modification by adding an emergency stop indicator system integrated with an Arduino Mega 2560 microcontroller, relay, contactor, buzzer, LED, DS3231 RTC module, and SD Card module. Applied Research and Development (R&D) methods were used in all stages, from design to testing. The test results showed that the emergency stop indicator system achieved a 100% reliability level in stopping the conveyor completely, with an average response time of less than 1 second. Visual and audio indicators were activated instantly (<0.1 seconds), ensuring the emergency warning was effectively communicated. Furthermore, the time-of-event recording to the SD Card functions well, providing accurate historical documentation. This modification proved effective in improving occupational safety and reducing potential damage to conveyors in the airport environment
