Green Energy Harvest Monitoring of Watering System for Smart Farming Using IoT

The development of electronics, computers, and information technology is very rapid. Still, in several developing and underdeveloped countries, certain groups, including farmers, have not felt significantly the benefits of these technological advances. One of the farmers’ problems is if there is a drought where the rice plants need water, but there is no rain, and the water supply from the river is insufficient, so the rice production process decreases, or the harvest even fails. Previous research stated that in India, most of the population, 70% of whom live in rural areas and are very dependent on agriculture, and research in Indonesia in 2019 showed that in 2017 44% of the population lived in rural areas with most of their profession being farmers. This article proposes to create a groundwater pump system for irrigating crops, especially rice. Groundwater pumps in rice fields far from fuel and electricity supply facilities are a problem. Therefore, using solar energy (PV) and wind energy (WT) is an effective and efficient alternative. A groundwater pump system can be placed in rice fields using batteries, battery energy obtained from photovoltaic (PV) solar panels, or wind energy using a wind turbine (WT). This article contributes to an experiment in making a water pump system by utilizing green energy from PV and WT to provide a plant irrigation system in rice fields. The energy source system can be monitored, and the water pump system can be controlled wirelessly using IoT technology. The experiments in this research use devices that represent the energy and water pump systems at a minimum. The experimental results show that the proposed system works well and can be implemented in a real rice field irrigation system.
