The utilization of oil empty bunches palm (EFBP) is limited, while the supply of EFBP is abundant. The most utilization of EFBP is in agriculture, while EFBP fibers have the opportunity to be developed in the field of engineering, for example as a composite material reinforcement material. In the construction field, EFBP fibers can contribute as a mixture of substances for cement tile products. The purpose of adding fiber is to distribute the stress on fibrous cement roof tiles. With evenly distributed stress, the strength of the tile will be higher. The production process of EFBP fibrous cement board is carried out without combustion, with materials in the form of portland cement, marble powder, CaCo3 powder and EFBP fiber and water. Based on the mechanical test that the fibrous EFBP tile can still be applied as a roof, this is evidenced by the majority of its mechanical properties meeting SNI standards. However, fibrous EFBP roof tiles have a flame spread value of 61.5 which means that they still need to be repaired so that the tile is not flammable. Thus, EFBP fibers can be used as an alternative fiber cement tile in order to improve product quality.Keywords: cement tile , fibre, EFBP

Inventories of oil palm empty fruit bunches palm (EFBP) at oil palm factories are very abundant. This will be a problem if the handling is not serious. Utilization of EFBP fiber as a technical material is one effort that can be done in order to help reduce the problem of EFBP waste in palm oil mill. EFBP fibers as the substance of fibrous cement board aims to reduce to the weight of the material without lowering its strength. The method of making fibrous cement board by mixing EFBP fiber into dough with 12% marble powder ratio, 10% CaCO3 powder and EFBP fiber volume and portland cement are varied. The addition of EFBP fibers as much as 16% of the total volume can decrease the weight by 15.2%. The results showed that the cement board based on EFBP fibers under optimum conditions has a tensile strength of 1.58 Mpa, density (ρ) of 1519 k g / cm3 and bending strength of 2.61 MPa. Thus, the addition of EFBP fiber to the production of cement board has the potential to be mass produced Keywords : cement board , fibre, EFBP

Palm oil mill issuesbyproducts in the form of 0.70 tons of cubic meters of fiber, 0.35 tons of cubic meters of shell,and 1.1 tons of cubic meters of oil palm empty fruit bunches palm (EFBP) to yield 1 ton cubic meters of crude palm oil.The fiber content consisted in the EFB is a source of fiber for a variety of industries such as manufacturing of composites, fillers for thermo-plastic, paper-making and sound insulation as well as soil erosion control.Manufacturing of a natural fiber reinforced cement board is an effort to reduce the use of synthetic fibers and asbestos fibers which cause side effects for its users.So this research is one of the breakthroughs to obtain new materials as substituteto asbestos fibers. This research used portland cement, marble powder, CaCO3 and EFBP fiber as reinforcement.EFBP fibers were arranged randomly in the form of short fibers. Percentage of the mixture of 16%, 12% marble powder, and portland cement was varied with a percentage of 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15% and the volume percentage of CaCO3 inverse of the percentage of portland cement. The results showed that the characteristics of fibrous EFBP cementboard in the optimum condition to produce value of tensile strength of 1.96 MPa, flexural strength of 2.61 MPa, compressive strength of 14.35 MPa, density (ρ) of 1519 kg/cm3, water absorption of 24.28 and flame propagation velocity between 54.4 to 61.5 FS.By the standard of JIS A 5417-1992 that the requirements of density in the construction of cement board is of 0.8 g/ cm3, so that the material is appropriate to be applied.Its thermal conductivity lower than fibrous congseted asbestos cement board λ = 0.576 kcal/mhoC, meaning that the cement board is worthy applied as a ceiling of the house.
