Monitoring and controlling earthworm cultivation site based on internet of things

Abstract

Earthworm is an organism that live in the soil. Earthworm has many species such as Amynthas Alexandri, Amynthas Morrisi, Eutyphoeus Incommodus, Eutyphoeus Waltoni, Metaphire Birmanica, Metaphire Houlleti, and Lumbricus Rubellus. Lumbricus Rubellus is an earthworm species that has many roles in agriculture and fish farm. Soil from Lumbricus Rubellus cultivation is more fertile than using chemical soil. Lumbricus Rubellus also can be use as fish feed for fish farm. This reason makes Lumbricus Rubellus has economic values. Many people start to cultivate Lumbricus Rubellus. The problem while cultivating Lumbricus Rubellus is controlling soil moisture in earthworm cultivation site. This research is aim to develop earthworm cultivation site based on Internet of Things (IoT). The IoT technology helps to monitoring and controlling soil moisture in earthworm cultivation site. To maintain moisture, earthworm cultivation site has 5 soil moisture sensors. Sensors position and sensors moisture value will be combined to make a decision for the system. If the system decision is the soil is dry, then the earthworm cultivation site will turn on the pump and squirt the water. The data research shows satisfying result. Sensors works very accurate while reading soil moisture with error rate of 1.26%, 1.11%, 0.98%, 1.26% and 1.00% respectively for each sensor while reading soil moisture in dry soil. The error rate sensor while reading humid soil is 1.14%, 1.02%, 1.19%, 1.28%, and 1.08% respectively. The system can maintain the soil moisture stable in 70%.
