Abstract

Indonesia is an agrarian country rich in agricultural commodities, one of which is dragon fruit. Dragon fruit has high economic value and health benefits. However, the productivity of dragon fruit plants is greatly influenced by the duration and intensity of sunlight, which becomes a challenge during the rainy season or days with low light intensity. This study aims to design an automatic lighting control system based on a microcontroller with On/Off scheduling features to support dragon fruit cultivation in Krajan Village, Yosomulyo Village, Banyuwangi Regency. This system utilises Internet of Things (IoT) technology and the NTP protocol for time synchronisation, enabling real-time monitoring of sensors and lighting control without direct user intervention. The method used involved the design and testing of the microcontroller from January to February 2025. Test results indicate that the use of yellow LED lights can enhance flowering and plant growth by extending photosynthesis duration, particularly at night. Thus, this system effectively increases dragon fruit productivity and quality while providing an efficient solution for farmers facing natural lighting limitations.

Abstract

Indonesia has abundant solar energy potential; however, its utilization remains limited due to dependence on fossil fuels and the low efficiency of solar panels caused by static installation systems. To address this issue, this study designed and developed a prototype of an automatic single-axis solar tracker based on Arduino Uno to optimize solar energy absorption. The system is controlled by the Arduino Uno R3 for automatic adjustment of the solar panel position, and the ESP32 is used for real-time monitoring of environmental and electrical parameters. The sensors employed include the BH1750 for light intensity, DHT22 for temperature and humidity, INA219 for voltage and current, and ACS712 for current. Test results indicate that the system is capable of automatically adjusting the solar panel angle, accurately monitoring environmental parameters, and generating stable electrical power for eight hours. Although some instability in current readings was observed when the system operated on battery power, the prototype has proven effective and feasible for further development to enhance the utilization of solar energy.

Abstract

The hatching process of chicken eggs is highly dependent on a stable incubation environment, especially consistent and standard temperature and humidity. Fluctuations or instability of conditions within the incubator can significantly reduce the success rate of egg hatching (hatching) as well as degrade the quality of the chicks produced. In response to this challenge, this study developed an Internet of Things (IoT)-based monitoring system. The system is designed to monitor crucial parameters such as temperature, humidity, electric current, and voltage inside the incubator. The data collected from the monitoring is then transmitted using the ESP32 module to the ThingSpeak platform. This integration allows users to monitor the condition of the incubator at any time and remotely over an internet connection, providing flexibility and ease of supervision. The test results show that the developed system is able to provide accurate and responsive environmental condition data, and plays an important role in maintaining the stability of the incubation environment. This is expected to increase egg hatchability and support the production of better quality chicks.
