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

There are four main weaknesses in using Oil Palm Stem (OPS) as a material for plywood manufacturing. High variation in density, moisture contents (MC), high water absorption and surface roughness. This paper report the investigation on the effect of water on physical properties of OPS plywood (PTA) namely water absorption, thickness swelling and delamination. These properties were compared with the properties of another two types of commercial OPS plywood denoted as PTB and PTC which were manufactured using OPS veneer with tropical hardwood veneer for face and back veneer and control plywood denoted as PTD which was manufactured using 100% tropical hardwood veneer. The results showed that PTA has lowest value of water absorption but has highest value of thickness swelling and delaminating.

O-MMT treated unsaturated polyester based hybrid composites were prepared using keratin fiber obtained from chicken feathers. Fibers of similar dimension were selected to fabricate composites through hand lay-up method. The preparation and dimensional stability properties of keratin fiber as reinforcements in composites is outlined in this paper. Varying O-MMT contents in nancomposites is performed to investigate the effects on the dimensional stability (water absorption and thickness swelling) of the composites. Results indicated that increasing fiber content deteriorates dimensional stability of the composites and composites. However, improvements in dimensional stability of the keratin fibercomposites were observed with O-MMT. O-MMT treatment reduces the water absorption and thickness swelling, especially at 5wt% of O-MMT concentrationat all range of fiber content. At 5wt% concentration of O-MMt, 10wt% keratin fiber content marks the lowest water absorption and thickness swelling with rate of 0.65% and 1.93%, respectively. Adopting 10wt% of keratin fiber at 5wt% of O-MMT can be utilized for application requiring high dimensional stability.

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%.

In this research the aim was produce and evaluate a plastic composite using recycled polypropylene (PP) and fibers from sugarcane bagasse residues (SC), without the use of additives. This analysis was based on laboratorial tests for physical and mechanical characterization, according to the standards ASTM D256-00, D638-101 and D570-98 were analyzed: water absorption, thickness swelling, impact resistance, tensile strength and its correspondent deformation. For comparison it was elaborated three different compositions: 100% PP; 80% PP+20%SC; 70%PP+30%SC. The results indicate a positive correlation with the content of fiber and water absorption and thickness swelling. In the tension tests, the composites with fibers increase the value of resistance for physical efforts, bringing advantages as durability and integrity of the material, showing a viability of the composites.

Oil palm empty fruit bunches (OPEFB) are a solid waste product from the oil palm industry that are about 70% fiber. Previous research has indicated that this fiber can be used to produce composite board. Gambier can be used in an adhesive to produce these boards as it has strong adhesive properties. This research investigates the suitability of four types of OPEFB fiber resulting from different mechanical separation speeds and three adhesive made from differing concentrations of Gambier (12%, 14%, 16%) to produce high quality composite board. The results of the research suggest the type of the fiber and the concentration of the gambier used significantly influence the density of the resulting board and that there are interactions between these two variables. The water content of the board is significantly influenced by the type of OPEFB fibre but not by the concentration of gambier or any interaction between these variables. Thickness swelling, modulus of rupture (MOR) and modulus of elasticity (MOE) are all influenced by type of fiber and concentration of gambier without any significant interaction between these two factors. The best types of fiber was those labeled A and B. The best performing composite board was produced from the longer B fibers and 16% gambier adhesive. This board a had density of 0.86 g/cm3, MOR 251.3 kg/cm2 and strength parallel to the grain of 145.6 kg/cm2. This data suggests that the density, water content and MOR of the boards made with this combination of material meets standard SNI 03-2105-2006 however the thickness swelling of the board fails this standard.
