Abstract :
In agriculture, fertilization is very important so that the plants or plants planted
can thrive if the plants have sufficient and regular fertilizer. Fertilizing plants by
farmers is still done manually, someone must bring a container containing
fertilizer and then give it one by one to the plants evenly so that it takes a lot of
time and energy to drain. In past research, research has been carried out with IoT
systems and watering systems with Arduino Uno control. Based on these
problems, the author will create a tool entitled Automatic Drip Fertilization
System on Arduino-Based Agricultural Land. Such tools can be easily used by
farmers for automatic fertilization of crops. The tool that will later be made has
regular fertilization system technology using Arduino Uno so that it can improve
the quality of agricultural products and farmers do not need to fertilize plants
manually anymore. Based on the test results when the power supply is given an
AC input voltage, the output voltage value is 230 V and if given a DC input
voltage, the output voltage value is 5 V. Testing the output voltage on the relay
when in active condition is 5 V and the RTC output voltage when in active
condition is 5 V. Testing the output voltage on the Arduino Uno when it is active
is 5 V at pin 5 V and is 3.30 V at VCC pin. Testing the output voltage on the water
pump engine when it is active at 230 V. Overall testing of the tool was carried out
7 times and 6 times successfully with 1 failure. It can be concluded that the
accuracy rate on the tool is 85 %.
