Soil is a growing medium for plants because it contains minerals needed for plants to grow and develop. The availability of minerals in the soil can gradually decrease and have an impact on plant development. Providing fertilizer to meet the nutrient needs of plants is still carried out at doses that have not been scientifically proven, which can have an adverse impact on plant growth. In the research, the system was designed with two setting modes for watering and fertilizing, namely automatic or manual. Automatic mode utilizes Internet of Things (IoT) technology as a remote control via website applications and mobile apps. Watering and fertilization controls are automatically adjusted based on scheduling on the website and mobile apps or manually according to the user's wishes, facilitated by fertilizer recommendations according to soil and plant type. This recommendation is obtained through the analysis of data sets such as soil type and plant characteristics, which are stored in the cloud via a website application to help farmers fertilize according to the plants they cultivate.
