Abstract

The agricultural sector is one of the main supporting sectors of the Indonesian economy today. However, there is one problem currently being faced by the agricultural sector in Indonesia, namely productivity. Various innovations have also emerged to increase the productivity of farmers, one way is to speed up pesticide spraying activities using UAVs or drones. Previously in 2017, a prototype pest spraying system was made using liquid media on an Unmanned Aerial Vehicle (UAV) platform with a quadcopter base where one of the main components of the drone sprayer is the nozzle. The nozzle has a function as an exit on the piping instrument. The way the nozzle works is that the flow that passes through this nozzle will change its pressure. The flow that comes out of this nozzle will change shape and direction. For example, the direction becomes spread with the form of a smaller (smooth) spark and high pressure. It was from this background that the idea emerged to conduct more in-depth research on the AMF-16 IF Drone, and this thesis discusses specifically the Nozzle of the AMF-16 IF Drone. The purpose of this study was to determine the discharge of each variation of the nozzle installation on the AMF-16 IF drone, the effectiveness of the spray area on the AMF-16 IF drone based on static tests and flight tests, and the comparison of static tests with flight tests. In this study, flight testing and static testing were carried out on a sprayer prototype in the form of a nozzle. The flight test will test the distribution of liquid from the nozzle when the drone flies, while the static test is a test of the distribution of liquid from the sprayer by hanging the sprayer on the test pole, in both tests below it has been prepared test paper to measure the spray area by the nozzle. In this test, there are variations of the nozzle using 2 nozzles and 4 nozzles, then also using variations in height during the test with a height of 40 cm and 80 cm. From the results of the tests carried out by the author in the form of static tests and flight tests, it can be concluded that the discharge at 2 nozzles (average 0.0129 L/second) is smaller than the discharge from 4 nozzles (average 0.0068 L/second), The number of nozzles affects the water flow in the spray. The experiment using 4 nozzles and a height variation of 80 cm became the most effective experiment with the results of a spray area of 13875 cm2 in the static test and 14400 cm2 in the flight test. The results of the largest spray area using 2 static test nozzles are wider than the flight test with a difference of 1125 cm2 and the largest spray area using 4 test nozzles is wider than the static test with a difference of 525 cm2.
