Performance Evaluation of Soil Substance Measurement System in Garlic Plant based on Internet of Things with Mesh Topology Network Scenario

Doan Perdana, Muhammad Imadudin, Gustommy Bisono


The high consumption followed by low production makes the government have to import garlic to meet domestic needs every year. To help increase garlic yields, a system designed to facilitate the process of measuring Nitrogen (N), Phosphorus (P), Potassium (K) content on plantation land in realtime using NPK sensor and nodemcu as microcontrollers and peovide the connectivity of realtime information using mesh topology. This system is an Internet of Things (IoT) based network, where internet connectivity is used to exchange information with each other with the objects around it. The result of the design of this system is a device to measure each element of N, P, and K as well as fertility status based on NPK values that have been obtained. And, with the IoT feature and mesh topology built in this device, the measurement data and whether or not the device works can be monitored easily through an android application that has been made on a smartphone. The mesh topology that built in this device is using painlessmesh library where the network built on the system is a true ad-hoc network, meaning that no-planning, central controller, or router is required.  Any system of 1 or more nodes will self-organize into fully functional mesh. We conclude that the accuracy of the measurement data compared to the NPK meter analog (Doctor Plant) is above 90%. Based on the durability test of the device and the system using Xiaomi's power bank of 5000mAh, the device and the system work well for 30 hours without any problems. Moreover, the accuracy of the data measured and uploaded to the database is no error with a 100% compatibility rate.
