Abstract

Unmanned Aerial Vehicle is a multirotor vehicle with more than one rotor to produce lift for the vehicle to fly in the air. Multirotor has become the object of research, one of which is in agriculture. Fertilization is more concerned about liquid fertilization, which is directly spraying on the leaves or foliar fertilizer. Foliar fertilizer sprayed with the hope that the stomata on the leaves can directly absorb the nutrients given. The UAV will fly carrying liquid (liquid) foliar fertilizer and spraying it on a predetermined land using a flight path that has been programming in the UAV. In previous research, we have used a multirotor type UAV combined with a foliar spraying system with a 1-liter liquid fertilizer, which can only spray land with a limited area. The limited liquid capacity will be a problem for the UAV because it is necessary to fill the liquid many times if used to spraying a wider area. Therefore, it is necessary to optimize the liquid load on the UAV so that its capacity will increase. If UAV's liquid foliar fertilizer's capacity increases, it will increase the area of foliar fertilizer spraying. This research focuses on increasing the UAV's lift capacity and designing a UAV system equipped with a sprayer. The increase in lift is related to the payload to be carried by the UAV. This research targets to optimally increase the load of liquid foliar fertilizer. In this research, the UAV was designing using a multi-rotor type. The measurements taken are the success rate of the system in flying over the crop field, testing the measurement of power, current, battery capacity, and different loading 40, 45,50, 55 percent of the total weight from an unmanned aerial vehicle.
