TEST VIBRATION IN TREATMENT OF AGAVE FIBER AND BAMBOO FIBER TO VARIATION OF FAKE DIRECTION
This study aims to (1) analyze the effect of agave fiber and bamboo fiber treatment on tensile strength and adhesive ability as composite material; (2) to analyze the effect of variation of vibrator placement on personal frequency and stiffness in composite beam agave fiber and bamboo fiber, analyzed the effects of variations in the direction of the fibers (0°/0°/0°), (-45°/0°/45°), and (-90°/0°/90 °) on the personal frequency and stiffness of the fiber composite agave and bamboo fiber, (4) comparing experimental analysis with numerical effect of variation of fiber direction from vibration test result using finite element method. This study uses finite element method for numerical analysis and spectrum method for experimental analysis. For finite element method in numerical analysis, the stem is divided into 5 elements while for the experimental analysis is done 4 eksposimental placement of eksiter, the pedestal used is simple. Material of the test material used is the composite beam of agave fiber and bamboo fiber. The treatment process of agave fiber and bamboo fiber using alkaline solution (NaOH) and Ethanol solution (C2H5OH) with soaking time of 1 hour and 3 hours for the first year. And for the second year it is planned to treat agave fiber and bamboo fiber, using alkali (NaOH) and Ethanol (C2H5OH) solution with 2 hours and 4 hours immersion time with 10%, 20%, 30%, and 40% %.
