Abstract

The rapid development of the palm oil industry in Indonesia over the time has resulted in an increase in waste from the production of processed palm oil such as empty palm oil bunches which are very disturbing for people living near the palm oil mill area. Oil palm empty fruit bunches waste can cause an unpleasant aroma, and not infrequently the waste is accidentally thrown into the riverso that it pollutes river water with the remaining oil content in it. There are many studies that examine how the strength of the composite material reinforced with oil palm empty fruit bunches, but the bending strength or the ability of the composite material to withstand buckling loads against variations in fiber volume fraction is not yet known. For this reason, in this study, the fabrication of fiber-reinforced composite material from waste oil palm empty fruit bunches with a Yukalac 157 BQTN-EX polyester resin binder and MEKPO catalyst will be carried out. Oil palm empty fruit bunch fiber composite material was fabricated with variations in fiber volume fraction of 9%, 11%, and 13% through the vacuum bagging method. Bending testing of composite materials with each fiber volume fraction was carried out using the three point bending method according to the ASTM D7264 standard. The results of this study are the manufacturing process and the value of the bending strength of the composite material of oil palm empty fruit bunches with fiber volume fractions of 9%, 11%, and 13%. Through the results of the bending test, the average bending stress value on the composite material of oil palm empty fruit bunches fiber with a fiber volume fraction of 9% is 42,65 MPa, 11% is 72,81 MPa, and 13% is 94,27 MPa.
