<br /> <p align="justify"> <br /> <br /> Hydroponics is one of the latest technique used in farming. Hydroponics replaces soil with nutrients enriched water, thus making the plants grow healthier and more efficient than conventional technique counterparts. One of the most common hydroponics technique is Nutrient Film Technique (NFT) who introduced by Allen Cooper. In this technique, plants are placed in channels with roots spread across a thin film of nutrients carried along the bottom of the channel that flow continuously. However, failure often occurs when the plant parameters are not being monitored and controlled regularly. Moreover, lack of knowledge about hydroponics can increase the chance of failure. <br /> <br /> Monitoring and Control for NFT Hydroponic (MoCoponic) is a system designed to automate the cultivation process of NFT hydroponic. The automation process includes nutrient level, acidity, and temperature solution. Furthermore, MoCoponic can also provide guides and has the ability to share to social media. There are four subsystems in MoCoponic, user interface, cloud, plant condition, and system control. Plant condition subsystem serves to know the state of the plant visually through pictures. Test results show the program runs automatically every 12 noon and data are stored in cloud. There is nutrient level control inside control system subsystem serves to monitor and control the amount of nutrient for plants. The implementation of this controller by measuring and regulating the conductivity of the solution inside reservoir using realtime feedback closed loop ON-OFF controller. Test results indicate that the readability and control of the conductivity of the solution is in accordance with the specification. However, the control can only be carried out using the same type of solution. <p align="justify"> <br />
