Polymers are materials with low strength and stiffness. Normally, fillers that act as strengthen medium are added to improve the mechanical properties of LDPE and composite LDPE reinforced EFB in different weight percentages, which are 1%, 2%, 3%, 4% and 5% were examined. EFB are residual organic fiber from oil palm processing and it is cheaper, light and recyclable. EFB that used were produced in the size between 1mm to 2mm. Previous research had been referring to identify the degradation temperature of LDPE and EFB. Specimens of this research were prepared through injection moldings method by using 160°C of barrel temperature, 80°C of mould temperature and 6.5 bar of pressure. Three mechanical tests had been done, included tensile tests (ISO R527) for Young's modulus and ultimate tensile strength, Charpy impact tests (ISO 179) to determine the impact strength and Shore durometer hardness tests (ASTM D2240) for hardness property. From the test result, mechanical properties were compared between LDPE and composites LDPE-EFB and the effects of increasing EFB content were also observed. Results indicated that Young's modulus and ultimate tensile strength increased after added EFB. Charpy impact strength for composite LDPE-EFB was lopwer that LDPE and decreasing with increasing weight fraction of EFB. Meanwhile, hardness for composites LDPE-EFB was greater than LDPE and increase with increasing weight fraction of EFB to 4%. When exceeded 4%, hardness of the composites decrease.
