Rancang Bangun Smart Hidroponik Kontrol pH dan Nutrisi

Abstract

Hydroponics,which is a farming pattern that empowers water as the basis fr plant growth, is very dependent on the nutrient contentin that water. The nutrient content dissolved in water has a different concentration value or total dissolve solid (ppm unit TDS)according to the nrrds and types of hydroponic plants. A tool for providing nutrition and automatic pH is designed based on the value of solution concentration and pH in hydroponic cultivation using the Arduino wemos microcontroller (ESP8266) as a data sender to web serve. This tool will continue to maintain the concentration an pH value of the hydroponic nutrient solution. I n this study the tool was applied to mustard plants with a concetration value maintained at 1000 ppm – 1500 ppm. This tools can automatically ensure that the nutrient solution water and also the pH will be maintained between 6 – 8. The result obtained in the system for adjusting the nutrient density value and the pH limit of he solution are automatically according to what is desired and can be monitored directly through the thingsview website wich can later be applied ro hydroponic plants on a large scale so that they can provide good result ana uality from hydroponic plants whithout having to done manually. The result of a comparison of plant growth with manual control devices and automatic control divices, growth in mustard plants for 14 days by automat control devices grows faster, plant height is 0,4 cm, leaf width is 0,1 cm, and the leaves are greener than manual controller.
