Design and implementation of smart gun sprayer of gulma controller tool of palm oil plantation in Bukit Kratai, Kampar District

Abstract

This article reports community service activities in implementing ergonomically designed weed control tools based on renewable energy, as well as measuring the effectiveness of using designed tools compared to conventional tools. The design and design of the gun sprayer was carried out with students from the University of Riau's integrated Real Work Lecture (KKN). The weed control tool is designed based on renewable energy which utilizes solar panels as a converter of solar energy into electrical energy to drive a DC pump brushless motor. The tool is designed by taking into account ergonomic anthropometric data for the average body posture of Indonesians as users. While the sprayer is designed in the form of a smart gun sprayer, the length of the sprayer gun can be adjusted from 1.2 m to 3 meters, with adjustable nozzles, while the hose has a length of up to 100 m, so that this smart sprayer gun can reach wider and higher weeds. From the tests carried out, this tool can reach agricultural land within a radius of 100 square meters and can complete weed control in an area of 2 hectares in about 6 hours. In addition, this service activity ensures that the use of weed control tools with a smart gun sprayer can reduce the risk of work accidents and can increase work productivity by around 300%.
