To improve the application and use value of Palm Oil Empty Fruit Bunch (OPEFB) waste as a composite material, the research team conducted research related to the utilization OPEFB fiber as an alternative material to replace carbon fiber in the manufacture of fuselage of Unmaned Aerial Vehicle (UAV). The low price of OPEFB, low of specific density and it’s abundant availability are the basis of research to apply it’s fiber as material of UAV fuselage. This research begins with the processing of OPEFB into fiber through an alkali treatment process. Furthermore, the process of maleated natural rubber as a mixture of resin matrix. Afterward, the fuselage is molded use hybrid fiberglass-OPEFB fiber and resin epoxy that has been mixed with natural rubber. Fuselage of UAV is also molded with material of hybrid fiberglass-fibercarbon. Based on mass measurements, the fuselage of hybrid fiberglass-OPEFB fiber material and the fuselage of hybrid fiberglass-carbon fiber material have a mass of 510 grams and 540 grams respectively. For deflection measurement, fuselage of hybrid fiberglass-OPEFB fiber material has a maximum deflection as 2.01 mm, while the fuselage of hybrid fiberglass-fibercarbon material has a maximum deflection as 1.19 mm. In statis impact test, the two fuselage are able to withstand shock load.

Composite is a new type of engineered material consisting of two or more materials in which the properties of each material differ from one another both chemical and physical properties and remain separate in the final result of the material. Composites have the characteristics of being lightweight, strong, not easy to corrode, and able to compete with metals. The addition of filler to the matrix aims to strengthen the composite board. Currently, the sugar palm industry in Klaten is growing rapidly and produces solid waste in the form of palm fiber. Besides paper production has increased to reach 13 million tons, the high demand for paper can cause more paper waste produced. In this study, the fillers used are natural fibers from palm waste and paper waste combined in polyester resin to produce good mechanical strength. The variation in this study is the difference in concentration in the palm fiber filler and paper. Comparison of palm fiber and paper as follows: 1,5 g:20 g), (2 g:15 g), (2,5 g:10 g), dan (3 g:5 g). In the fracture constancy test or modulus rupture (MOR), the results obtained in variation A showed results of 178,64 kgf/cm3, variation B of 159,6 kgf/cm3, variation of C was 131,32 kgf/cm3, and variation D is 80,92 kgf/cm3. Variation A shows the best value that is 178,64 kgf/cm3, the results are in accordance with SNI composite board No. 03-2105-2006.

The mechanical properties of fibrous concrete reviewed in this research are flexural tensile, compressive, and split tensile strength. This paper is a review of many researchers on plastic, steel, and organic fiber concrete. The plastic fiber reviewed in this paper is a concrete mixture with mineral water glass waste with a volume fraction of 0.25% and L/d 37.5; steel fiber is the straight type while organic fibrous fiber is coconut husks, jute, the leaves of palm oil plants, sisal, hemp, banana leaves, pineapple leaves, bamboo bark, horse dung, rice straw, and gelam-bark. The performance of the three mechanical properties of non-fibrous concrete in each study is calculated in percentage. The mixtures that have superior mechanical properties are 0.5%, 2% steel-fibrous concrete (St0.5 and Sj2), 2% with aspect ratios of 75 and 50 (Ss0.5), 0.6% bamboo-bark fibrous concrete (B0.6) and 0.4% gelam-bark fibrous concrete (G0.4). The St 0.5 and Ss 0.5 showed increased tensile strength in the splitting test, but the increase for St 0.5 of the compressive strength was below B0.6 and G0.4. The B0.6 shows an increase in the splitting test of 45% while G0.4 shows an even increase of ± 7.5% in the three mechanical properties. Flexural tensile strength is not a function of compressive strength. The reduction in the level of ease of mixing in gelam bark fibrous concrete (G0.4) is the lowest compared to bamboo fibrous concrete with a volume fraction of 0.6 and steel-fibrous concrete. The flexural strength and compressive strength of plastic-fiber concrete are 2.1% and 4.7% higher, respectively than non-fiber concrete. The addition of plastic fiber is easier to mix than the addition of steel fiber.
