Rancang Alat Pengusir Hama pada Tanaman Jeruk Menggunakan Nodemcu ESP8266 dan Pengontrol Berbasis Modul Gelombang Ultrasonik

Abstract

The development of electronic instrumentation technology is currently grow-ing rapidly. Advances in instrumentation technology are also very helpful in various sectors, one of which is the agricultural sector. Management of citrus plants shows that there are various types of pests and diseases associated with citrus plants. Cur-rently, many farmers complain that the harvest yields are getting less and less optimal, this is due to the number of pests on citrus plants which causes harvesting results to continue to decline. With the development of advanced technology, it is now possible to build a system that is able to anticipate and minimize pest attacks on citrus plants. One of them is using ultrasonic waves as a repellent and movement sensors that can help farmers detect pests and repel pests on citrus plants. On this occasion the author designed an automation tool that can help facilitate the work of farmers in protecting citrus plants from pests without using chemicals. The mechanism for making this pest repellent is quite simple by using an ultrasonic sensor that is installed as a pest detection device and an LED whose light is smeared with oil is used as a pest trap. This tool is also equipped with an application that is connected to a nodeMCU Wi-Fi module for connectivity which helps the performance of the tool so that the tool can be con-trolled via an application on a smartphone.
