Rancangan Sitem Pembuangan Air Hujan Otomatis pada Tanaman Hidroponik Nft Menggunakan Mikrokontroler

Abstract

Hydroponics has been widely done by the people of Indonesia. But in its application, many factors determine the success of hydroponic vegetable cultivation, including nutrients, planting media, oxygen and water. In addition to providing appropriate nutrition, there is another factor that must be considered namely rainfall. When it rains, rainwater will mix with nutrient water and this will cause nutrient water levels to decrease or disappear. So, after the rain stops, the thing to do is check the condition of the nutrient content of the water and add nutrient water to keep it by the levels needed by plants. One way that is often used to protect hydroponic plants from rainwater is to build a greenhouse. However, making a greenhouse itself requires a lot of money, the costs incurred for making greenhouse can reach millions or even tens of millions of rupian. To overcome this while saving costs, through this study, the author created an automatic rainwater disposal control system on nft hydroponic plants using a microcontroller. Where later the results of this study show that the tool will work automatically when rain comes to dispose of rainwater so that it does not mix with nutrient water in the reservoir.
