Design of Automatic Insect Trap Hypothenemus hampei Ferr. based on Solar Cells as a Source of Stinging Energy

Abstract

One of the plant-disturbing organisms that always harms coffee plants is the insect Hypothenemus hampei Ferr. which causes fruit borer attacks. This study aims to design a solar panel-based H. hampei trapper. This tool is designed to work automatically according to the settings on the solar charge controller; it can catch H. hampei effectively; this tool has a low current (DC) that is safe for farmers; this tool can be used in plantation areas far from PLN because the source of electrical energy comes from solar cells; maintenance costs are relatively cheap, but the tool is designed to operate in the long term. The H. hampei trap uses solar panels as an energy source and is equipped with a stinger that works automatically by utilizing the solar charge controller feature. The functional test results show that the tool that has been designed can work well according to the plan made. The average consumption of stingers is 23.70 Wh. The average panel energy yield is 26.85 Wh. The panels’ energy output has exceeded the amount of energy the stingers need. The tool is designed to trap H. hampei well.
