Abstract

Soil nutrition or plant nutrition is an important factor in plant growth which can be compared as food for plants. one of the factors that support plants to grow optimally is the availability of adequate nutrients in the soil. Nutrient content in the soil can be determined by taking soil samples and doing laboratory testing. In addition to Lab tests. sensors can be used to determine nutrients and as a monitoring system for planting land. This soil nutrient monitoring system can be integrated with a wireless system and form a wireless sensor network (WSN). WSN developed is an Internet of Things (IoT) based system so that it can be accessed through the internet network. This research was conducted using the Network Development Life Cycle (NDLC) method which consists of six stages namely analysis, design, prototype simulation, implementation, monitoring and management. This research resulted in a prototype WSN system to detect the availability of nutrients in the planting area and can provide certain treatment in accordance with the data obtained by the sensor. The prototype developed will be tested to determine the accuracy of the data obtained. After this research, the prototype was carried out using the Internet of Things (IoT) system.
