Design of Wood Pellet Trolley using Finite Element Method (FEM) and Design for Assembly (DFA) Approach at PT. Perkebunan Nusantara VIII Ciater

Abstract

PT. Perkebunan Nusantara VIII is a company produces orthodox black tea. The wood pellets distribution in drying station still uses human power without any tools. The process is done as far as five meters with the transport time of each sack for three minutes and the weight is 30 kg. In the previous research has produced a design that used as reference in this research. The purpose of the research is to provide trolley design by applying Finite Element Method and Design for Assembly approach. The method is chosen because the trolley force should be considered so the trolley has good strength. The initially complex and inflexible designs are expected to be simpler and more efficient. The results of this research are wooden pellet trolleys on handle, platform, frame, and stairs chunk are considered safe from the results of the test. While the wheels chunk need to be re-election of material into titanium alloy because it is considered unsafe based on the test results. Then the design of wooden pellet trolleys results in a higher assembly efficiency rating of 27.77% with 127 total components and total processing time of 928.98 seconds so it can be concluded better than reference design.
