Abstract

Room temperature and humidity in tropical climates, such as in Indonesia, are generally controlled using air conditioning (AC), which has now become a basic necessity. This study aims to improve the durability and energy efficiency of air conditioning systems through the application of microcontroller-based devices. Monitoring is carried out by measuring the AC electrical current, where the normal value is in the range of 3.2–3.6 amperes, while when the current exceeds 4 amperes, the system automatically cuts off the electricity supply. In addition, a water level control sensor with a maximum limit of ±4 cm is installed on the inner water tank. If the water level reaches ±3 cm and touches the sensor, the system will automatically stop the AC operation. To support remote monitoring, the system is equipped with an Arduino NodeMCU ESP-32 module integrated with the Blynk application, so that users receive notifications when a disturbance occurs. Real-time monitoring information is also displayed on the LCD screen on the control panel. The results of the study show that this design is able to provide protection against damage caused by excessive current and water levels, while also increasing the operational efficiency of the AC.

Abstract

The growth of water and land transportation traffic in Indonesia often causes conflicts on conventional bridges, especially in river areas frequently crossed by large vessels. This condition has the potential to cause accidents and disrupt traffic mobility. This study aims to design and implement a smart bridge control system based on Arduino Uno that can operate automatically to improve the safety and efficiency of lift bridge operations. The research employed a Research and Development (R&D) approach with a prototype method. The system utilizes Arduino Uno as the main microcontroller, HC-SR04 ultrasonic sensor to detect ships, SG90 servo motors as actuators for driving the bridge and barrier gates, along with a 16x2 LCD, traffic light module, and buzzer as indicators. The bridge opening and closing process is controlled automatically with a programmed safety sequence. The test results show that the system is able to detect vessels, provide early warnings, close the barrier gates, lift the bridge, and automatically return to normal conditions with good response. This system successfully minimizes human error and provides real-time information to road users through the LCD display and traffic lights.

Abstract

Perkembangan teknologi mendorong penerapan sistem yang lebih efisien dalam pengelolaan area parkir. Keterbatasan lahan parkir dan kurangnya sistem monitoring terintegrasi sering menyebabkan kesulitan dalam mengetahui ketersediaan slot parkir serta menimbulkan penumpukan kendaraan. Penelitian ini bertujuan untuk merancang dan membangun Smart Parking System berbasis Internet of Things (IoT) yang mampu menyediakan informasi ketersediaan parkir secara cepat dan akurat. Metode yang digunakan meliputi perancangan sistem, implementasi perangkat keras dan perangkat lunak, perakitan komponen, pembuatan program, serta pengujian kinerja sistem. Sistem memanfaatkan sensor ultrasonik untuk mendeteksi keberadaan kendaraan, mikrokontroler sebagai pengolah data, seven segment display sebagai media informasi lokal, dan aplikasi Telegram sebagai media monitoring jarak jauh. Hasil pengujian menunjukkan bahwa sistem berhasil menjalankan fungsi masuk dan keluar kendaraan, memperbarui informasi ketersediaan parkir, mengamankan akses pengguna, serta mengirimkan notifikasi melalui Telegram secara real-time. Dengan demikian, sistem yang dirancang dapat meningkatkan efektivitas pengelolaan parkir dan memudahkan pengguna dalam memantau ketersediaan parkir dari jarak jauh.

Abstract

The use of Liquefied Petroleum Gas (LPG) as a household fuel continues to increase due to its practicality and efficiency. However, the use of LPG also poses a risk of gas leakage, which may lead to fires or explosions if not detected at an early stage. This study aims to design and develop a gas leakage detection system prototype based on Arduino Uno using an MQ-2 sensor in a miniature kitchen environment. The research employed a prototype development method, including hardware design, system programming, and device testing. The prototype was designed as a miniature room measuring 40 cm × 35 cm × 27 cm and equipped with an MQ-2 sensor, a 16×2 LCD, LEDs, a buzzer, servo motors, and a DC fan. The test results showed that the MQ-2 sensor was capable of detecting gas leakage effectively based on changes in sensor readings. At sensor values of 0–99, the system remained in a safe condition, indicated by the green LED being active while all actuators remained inactive. Meanwhile, at sensor values of 100–400, the system detected gas leakage and automatically activated the red LED, buzzer, DC fan, and servo motors to open the room ventilation. The LCD also successfully displayed real-time system status information. Based on the testing results, the developed prototype was able to detect gas leakage and provide automatic responses as an initial mitigation effort to improve household safety.

Abstract

The availability of sufficient and high-quality water is essential in daily life. However, monitoring water levels and water quality in storage tanks is still commonly performed manually, making the process less efficient and potentially causing delays in water refilling and the use of unsuitable water. The development of Internet of Things (IoT) technology enables water monitoring and control to be carried out automatically and in real time. This study aims to design and develop an IoT-based Smart Water Tank system using a dual-tank concept to monitor water levels and water quality automatically. The methods employed include system design, ESP32 programming, integration of water level and turbidity sensors, and system testing. The test results showed that at water volumes of 0–500 mL, the pump was activated to fill the tank. When turbid water was detected at 1000–1500 mL, the filtration system was activated automatically. At 2000 mL, the pump and filter stopped operating because the tank was full and the water was clear. Monitoring data could also be accessed in real time through Google Spreadsheet. The developed system integrates automatic water monitoring and management to improve the efficiency of water storage management.Key words : Smart Water Tank, Internet of Things, ESP32, Water Level Sensor, Turbidity Sensor.
