Of course this affects the stability of farming especially in urban areas. Hydroponics is one of the smart solutions that can be taken to grow crops in narrow areas or even without land. hydroponics really need a controlled environment to avoid decreasing the quality of plants until the plants wither. One important parameter is the degree of acidity (pH) of the nutrient solution, where pH is very influential on the solubility and availability of nutrients in the nutrient solution. The development of the IoT (Internet of Things) currently covers various aspects, one of which is in agriculture, with the MQTT Broker protocol monitoring and measuring plant pH on a hydroponic system can be done remotely. The method used is to use PID control where the pH of the plant will reach a set point that is determined stably. The expected result is that it can help to control plant pH remotely through andoroid to prevent deterioration in plant quality.</em></p>}, number={2}, journal={Systemic: Information System and Informatics Journal}, author={Retna Wardani, Ika Indriani and Kunto Eko Susilo}, year={2021}, month={Jan.}, pages={27–32} }
