Modifikasi sistem penyemprotan untuk pengendalian gulma menggunakan sprayer gendong elektrik

Abstract

In agriculture, spraying aims to protect crops from disrupting organisms to increase farmers’ profits. Spraying using a spraying tool has an advantage in that it spreads granules evenly to plants; furthermore, the size of the granules can be adjusted according to the need. This research aimed to modify the spraying system on the sprayer output to reduce the shift in spraying points on sprayed granules as a result of the wind blow from the environment. This electric sprayer consists of several components which are not found in a power sprayer or manual sprayer such as a 12-V battery or a 5.8 bar-pressure water pump. The result of the pressure comparison on the outlet showed a significant difference, namely in a 3-bar manual sprayer and a 4-bar electric sprayer. The pressure difference resulted in the difference in discharge, the length and width of the spraying.
