Agricultural cultivation through precision farming systems can reduce production costs, increase yields and improve crop quality. One way to develop precision farming systems is to design pest insect traps for horticultural plants. Pest insects can damage up to 90% of plant tissue, which causes crop failure. Nowadays, many modern pest traps have a disadvantage in using a type of fan actuator in the trap system embedded in it. Fan type actuators embedded in modern pest traps are considered to be still less effective for capturing pest insects in the catchment area. In this study, the effectiveness of the percentage of capture through various types of fan actuators was calculated through microcontrollers (Arduino). The microcontroller was connected to the infrared sensor type E18-D50NK as a detector for the number of insects. The working principle of the infrared sensor E18-D50NK in this study is to respond to the microcontroller when infrared light is blocked by insect pests. The dimensions of insect pests that can be detected by this sensor are more than 1 mm. Infrared sensors were mounted around the lights to detect the number of insects approaching the light. The experiment in this study used a driving fan actuator, suction fan and fanless actuator. An 18 watt fluorescent lamp was used to lure insects into a trap. Nature of pests insects attracted to light try to get close to the lights. Sensors that detect the presence of passing insects automatically carry out the summation recorded in the data logger.
