Sistem Irigasi Otomatis untuk Tanaman Terong dengan Menggunakan Mikrokontroller STM32 dan Sensor Kelembaban Tanah

Abstract

Irrigation is a process of artificially applying water to the soil for the growth o f agricultural crops in the world of modern agriculture, but currently there are certainly many types of irrigation created by humans. Irrigation is also a pattern of watering plants that requires sufficient water for plants to get a supply of water accord ing to what is needed. The problem that is often encountered when using manual irrigation is the limited time to continuously monitor the condition of soil moisture on agricultural land, in this case the eggplant type. There fore we need a tool that helps flow the water supply according to the needs of the plants so that the soil reaches the moisture level needed by the plants. A device is designed to regulate the supply of water that will flow into the planting medium (soil) automatically according to the humidity required based on the required soil moisture value using the STM32 microcontroller as the receiving medium and providing data to the server. This tool will continue to maintain the value of soil moisture to keep it according to needs. In this stud y the tool was applied to eggplant plants, where the required humidity value was 65%. After that each development will be measured such as plant height, leaf width, and fruit that appears. The results of a comparison of the growth of eggplant plants manual ly and eggplant plants with a soil moisture sensor with the STM32 microcontroller, eggplant plant growth will be recorded once a week and carried out for approximately 3 months
