Abstract

One of the irrigation systems that can be used for horticulture is the sprinkler irrigation system. This irrigation system can optimize farming activities if it is equipped with a control system, but the development of this system is still lacking, especially for olericulture. Therefore, the purpose of this research is to develop a sprinkler irrigation system using a microcontroller that functions as an automatic controller in determining the interval and volume of watering based on time. To develop the system, the research and development (R&D) method was used, where the development of the sprinkler irrigation control system starts from the control system designing, prototype making, functional testing, field testing, and data analysis. This study resulted in an automatic sprinkler irrigation system with 4 sprinklers, a height of 1.5 meters, and water pressure on each sprinkler was about 11 Psi. Based on the test results, the average diameter of the spray was 7 meters, and the average volume of spray every one minute was 6700 ml. The control system response test for spraying time only produces an error value of 0.9%. Based on the results obtained, the developed sprinkler irrigation system can function properly based on the spraying time interval and can spray the desired volume of water.
