Modifikasi Nosel pada Sistem Penyemprotan untuk Pengendalian Gulma Menggunakan Sprayer Gendong Elektrik

Abstract

This research aimed to modify the Nozzle of 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
