Abstract

The case of crop failure caused by pest attacks is one of the problems in agriculture that is always interesting to study. Apart from weather factors, pest attacks on rice and corn agricultural commodities often occur just before harvest time. Currently, farmers often use toxic materials and even electricity as a means to repel and eradicate rat pests. However, this method can be dangerous for the farmers themselves. There have even been several cases of death due to electrical equipment installed in agricultural areas. Based on these problems, a pest repellent will be made by utilizing ultrasonic waves from a solar-powered power source so that it can be used efficiently, practically and safely. This tool is built using IC NE556C, Solar Panel, LDR Sensor (Light Dependent Resistor), and Ultrasonic Piezo PTC 4000 Speaker. IC NE556C timer and ultrasonic wave multivibrator are used to generate ultrasonic waves randomly according to the program. The purpose of making this tool is as an alternative to field mouse pest repellent using ultrasonic waves by utilizing solar energy in handling pests in agricultural areas.

Abstract

The problem of garbage is not a new thing from the past until now, garbage is still the center of attention and a prolonged problem because of the various impacts of the problems that are caused and felt. Many factors are the cause of the increasing amount of garbage every day, including the lack of self-awareness about maintaining cleanliness and disposing of garbage in its place. This study aims to develop an IoT-based garbage collection robot. The method in developing this garbage collection robot is using the Fuzzy Mamdani method. The IoT-based garbage collection robot is designed using the Arduino Uno microcontroller as well as the Node MCU ESP 8266, HC-SR04 sensor, DHT11 sensor, SG90 Servo motor, DC motor and L298N motor driver. The way this robot works is to detect the distance with the HC-SR04 sensor as a distance data input then processed by the Arduino microcontroller and then the SG90 servo motor will move to clamp the garbage automatically and for the robot using control via a smartphone to be directed to the destination garbage. The results of this study are that the robot can clamp or pick up garbage with a distance of less than 5 cm and can control the speed of a DC motor using the fuzzy Mamdani method.
