Oil palm empty fruit bunches (OPEFB) fiber were industrial waste that has not been widely used by the community, only stacked and cause odors that interfere with the surrounding environment. This research studied the utilization of OPEFB fiber for cement board products using cement as resin and CaCl2 as accelerator. Laboratory scale cement board made from OPEFB fiber were mixed with cement, and CaCl2. The composition of fiber and cement were 1:1, 1:1.5, 1:2, and CaCl2 variations were 0%, 1% and 3%. A mixture of fibers, cement and CaCl2 was compressed at the pressure of 4 ton for 24 hours. The cement boards were tested for physical and mechanical properties according to JIS A 5417-1992, and the results were compared to the requirements of the cement board JIS A 5417-1992. Cement board made from fiber and cement composition 1:1.5 and CaCl2 content 3% produced moisture content, thickness swelling, water absorption, density, modulus of rupture/MOR, modulus of elasticity/MOE and screw withdrawal strength that met the requirement of JIS A 5417-1992. The composition of fiber and cement and the variations of CaCl2 content produced significant effect on water content, water absorption, thickness swelling, modulus of rupture/MOR, modulus of elasticity/MOE and screw withdrawal strength on cement boards.Keywords : oil palm empty fruit bunches fiber, cement boards, physical and mechanical properties

The Impact

Study of the size effect of natural fibre from oil palm empty fruit bunches (OPEFB) as filler, onto the mechanical and physical properties of fibre reinforced biocomposites based on recycled Acrylonitrile Butadiene Styrene (ABS) has been done. The OPEFB fibres were prepared by mechanical milling and sieving to obtain medium-fibre (20 mesh) and short-fibre (100 mesh). The biocomposites have been produced by extrusion using single-screw extruder method. Mechanical properties and S of biocomposites were evaluated and compared with glass fibre (GF) filled composite which is commonly used in plastics industrial applications. The result showed that the impact strength increased with the decreasing of OPEFB fibre size, while the Young’s modulus decreased. Other mechanical properties of biocomposites with short-fibre (RABS/SF) and medium-fibre (RABS/MF) filler were not significantly different at 95% confidence interval. Impact strength of short-fibre filled biocomposite was higher than glass fibre filled composites. The surface free energy of biocomposites lower than glass fibre filled composites, but its dispersive components are higher, indicating more hydrophobic feature of the surface. The fabricated micro-fibre of OPEFB can be used as viable alternative to substitute glass fibre as filler materials of composites.

This paper focus on Madar and Bauhinia Racemosa fibers has high potential as reinforcing agents in polymer composites. The composites plates were fabricated by hand layup method with varying the fiber weight percentage of 5%,10%,15% and 20% on mechanical and water absorption properties are analyzed. The mechanical properties of such as tensile, flexural and impact properties of madar and Bauhinia Racemosa fiber mat reinforced polyester composites were studied at first time in this work. The tensile, flexural and impact strength of Bauhinia Racemosa fiber mat reinforced polyester composites had proved higher strength performance than the madar fiber mat reinforced polyester composites.

Palm shells are one of the wastes produced from the processing of crude palm oil in addition to empty fruit bunches and coir which account for 60% of oil production. Palm oil shell waste is widely used as active charcoal in the oil, rubber, sugar, and pharmaceutical industries. The potential of palm oil shell waste in Indonesia is very large considering the area of oil palm plantations which continues to increase every year. This study aims to determine the percentage of the addition of palm oil shell waste in the manufacture of paving blocks that provide optimum compressive strength and water absorption values from several variations of the addition of palm oil shell waste that replaces some of the fine aggregates. The study was carried out experimentally in a laboratory using a boxed specimen with a length of 20 cm, a width of 10 cm, a height of 6 cm by 40 pieces. The mixture uses a ratio of 1 cement and 5 sand with fas 0.3. Treatment of test specimens by immersion in water for further testing of compressive strength and absorption at the age of 28 days. Based on testing of the compressive strength of paving blocks with a percentage of 0%, 5%, 10%, 15% are respectively 8.08 MPa, 7.18 MPa, 6.46 MPa, 5.94 MPa. The value of paving block water absorption with a percentage of 0%, 5%, 10%, 15% are respectively 9.88%, 10.25%, 12.27%, 12.44%.

Oil palm wood is the primary biomass waste produced from plantations, comprising up to 70% of the volume of trunks. It has been used in non-structural materials, such as plywood, lumber, and particleboard. However, one aspect has not been disclosed, namely, its use in thermal insulation materials. In this study, we investigated the thermal conductivity and the mechanical and physical properties of bio-insulation materials based on oil palm wood. The effects of hybridization and particle size on the properties of the panels were also evaluated. Oil palm wood and ramie were applied as reinforcements, and tapioca starch was applied as a bio-binder. Panels were prepared using a hot press at a temperature of 150 °C and constant pressure of 9.8 MPa. Thermal conductivity, bending strength, water absorption, dimensional stability, and thermogravimetric tests were performed to evaluate the properties of the panels. The results show that hybridization and particle size significantly affected the properties of the panels. The density and thermal conductivity of the panels were in the ranges of 0.66–0.79 g/cm3 and 0.067–0.154 W/mK, respectively. The least thermal conductivity, i.e., 0.067 W/mK, was obtained for the hybrid panels with coarse particles at density 0.66 g/cm3. The lowest water absorption (54.75%) and thickness swelling (18.18%) were found in the hybrid panels with fine particles. The observed mechanical properties were a bending strength of 11.49–18.15 MPa and a modulus of elasticity of 1864–3093 MPa. Thermogravimetric analysis showed that hybrid panels had better thermal stability than pure panels. Overall, the hybrid panels manufactured with a coarse particle size exhibited better thermal resistance and mechanical properties than did other panels. Our results show that oil palm wood wastes are a promising candidate for thermal insulation materials.
