Abstract

One of the factors causing the decline in national rice production is the attack of pests on rice. Based on data obtained from the agricultural department which has been processed by local data, it is known that there are 6 types of pests that attack rice plants in Indonesia, namely brown planthoppers, rats, rice stem borer, blast, kresek leaves and tungro. One method that can be used to repel pests in rice is by utilizing ultrasonic waves but is still limited to a range of only 4 meters in intensity. Therefore, a research aimed at generating ultrasonic waves will be carried out with the intensity of the ultrasonic wave range reaching 20 meters. The stages of research carried out include collecting data, analyzing data, designing circuit design, implementing circuit design, testing circuit design implementation and testing circuit design implementation. The ultrasonic wave generator designed in this study consists of 2 parts, namely a frequency generator of 20 - 50Khz and an amplifier of the output amplitude. Tests carried out in the research are still on the frequency generator section and the results show that the frequency variation of 20 - 50Khz can be produced properly by the ATMEGA 16 microcontroller.

Abstract

Objects can be interpreted as all inanimate and living things that have various shapes and sizes. For humans to determine the presence of objects, to classify and estimate the distance of objects around them is not difficult. But for a computer to do the work mentioned above with an accuracy level that reaches up to greater than 90% is not easy. Object detection is important in the field of computer vision because it is used to monitor and track objects, while robots that use cameras as sensors are used to avoid obstacles, follow objects, classify and so on. Therefore the purpose of this study was to determine the level of accuracy of the CNN method in classifying objects, especially handwriting. The steps used to complete this research were literature study, collecting digital image data, determining training and testing data, designing the CNN program, conducting training and testing. From the results of testing the CNN method that has been carried out, it is known that the level of accuracy in classifying handwritten forms reaches 90%.
