Rekayasa Material Filament Biocomposite Tandan Kosong Kelapa Sawit Dan Plastik High Density Polyethylene Untuk 3D Printing Berbasis Fused Deposition Modeling

Abstract

High Density Polyethylene plastic is a type of plastic that is widely used as bottle packaging products. Waste from the type of High Density Polyethylene (HDPE) plastic is a material that is difficult to decompose and will be a potential cause of slums. In addition, Indonesia is also a producer of abundant oil palm plantations. The rest of the production will produce solid waste, namely Oil Palm Empty Fruit Bunches (OPEFB). From these problems in this study, HDPE plastic waste and OPEFB waste will be used as bicomposite filaments for printing materials on 3D Printers. This study aims to obtain the mechanical strength of biocomposite filaments against the addition of OPEFB fiber filler particles in the HDPE matrix. Biocomposites were made using the extrusion method on an extruder machine in the manufacture of filaments and the Fused Deposition Modeling method on a 3D Printer machine in the manufacture of test specimens. The mechanical properties tested were tensile test, with the results of the maximum tensile strengthof OPEFB-HDPE specimens and HDPE specimens being 7.02 MPa and 5.32 MPa, respectively. Judging from the data, there is an increase of 31.97% in the maximum tensile strength to the addition of OPEFB fiber filler particles in the HDPE plastic matrix. Factors that increase the mechanical strength of specimens made from OPEFB-HDPE include the addition of filler material, the binding material (compatible) and the right temperature setting is also one of the factors that increase the strength of the mechanical material.
