Abstract :

Spraying operation in a rice field is considered as the most harmful operation since the operator has to deal with the toxic chemicals and prolong and frequent exposure. Drone provides an effective method for such operation by reducing time of operation at least about one-third compared to the conventional. The test was conducted in the rice field, tested for uniformity and drift effect from using drone versus knapsack sprayer methods. About 1000 samples were collected for all treatments imposed. The uniformity of the spraying at 2 m height using drone is similar as using knapsack sprayer, with CV value at 0.46 and 0.43, respectively. Both methods of spraying causes a drift to travel up to 25 m away from the spraying source. Flying height between 1.5 m and 2 m from the crop canopy is suggested to be the best considering best uniformity pattern and at minimum drift could occur. This study is expected to provide an information and recommendation of the effectiveness by means of drone for spraying operation in rice production. The impact is not only for the food safety and security, but also for the farmer’s income by reduction of the production cost.
