Monitoring pengukuran PH tanah pada pupuk sawit berbasis internet of things

Abstract

Palm oil is an industrial plant that produces both cooking oil, industrial oil, and fuel. The palm tree has an important role in the oil industry in replacing the coconut as a source for its raw materials, but plants need attention to produce fruit properly, so a system of monitoring, measuring the ph of the soil on cast-based mulch. The system can identify the moisture of the soil, ground ph, and display the value of moisture levels and ground ph through LCD, installed sensors and forwarded to the owner's smartphone for his plant monitoring through the blynk application. The tool system already USES 10wp's solar cell as the main energy and the diesel cell controller as to configure the entry stream to the battery and take it from the battery to load, from the testing results can run the load for the +/- 21 hours. The components needed to build a iot system are microcontrols, sensors, stepdown, LCD, solar cell, solar cell controller, BMS, battery. From the results of the humidity sensor testing it has a 75%-80% accuracy and ground ph sensors have an accuracy of 4-6.5.. The system of monitoring that the ph measurement of soil on a low-based bsawite fertilizer is needed to help the plant owners assess the soil condition through the blynk application and to optimize the plant.
