Prototype of Control System for Watering and Spraying Pesticide on Shallot Plants Based on Microcontroller

Abstract

Shallots are one type of annual plant that belongs to the Liliaceae family. This plant is useful as a seasoning for cooking, as well as a source of much-needed vitamin C, protein, fat, and carbohydrates. On onion plants, there are  several  things  that  need  to  be  considered,  including  watering  and  spraying  pesticides.  In  watering  and spraying pesticides, it is still done manually. Sometimes onion farmers spend too much time and are less efficient in their work, so a water irrigation and pesticide spraying system is made on onion plants on a scheduled basis. This system uses a soil moisture sensor to read data on the amount of water content in the soil, when the sensor detects  the  soil,  the  sensor  will  read  moist  or  dry  data.  And  the  Real  Time  Clock  (RTC)  functions  as  a  timer, where the specified time has arrived, the RTC will turn on the DC Motor and DC Pump. The DC motor functions as  a  driving  force  for  the  spraying  device,  and  the  DC  Pump  functions  as  pumping  water  according  to  a specified schedule. This system uses an Arduino Uno microcontroller as a controller of the soil moisture sensor and RTC. The result of this research is the formation of watering and spraying pesticides that make it easier for farmers to water and spray pesticides on shallot plants.
