Analisa Uji Tarik Komposit Berpenguat Serat Daun Nanas Dengan Variasi Susunan Menggunakan Perlakuan Alkali

Abstract

Pineapple leaf waste is increasing and less than optimal for its utilization. Although some of the pineapple leaf waste is used as fertilizer for new pineapple plant nurseries. Many researchers have analyzed pineapple leaf fibers to be used as reinforcement in composite materials. The purpose of this study was to analyze the effect of the strength of the pineapple leaf fiber-reinforced composite with alkali (NaOH) treatment, the effect of fiber composition versus resin, and the effect of fiber direction arrangement on the tensile test. So that the rest of the pineapple leaves can be utilized and can reduce pineapple leaf waste. In this study using pineapple leaf fiber and given 5% alkali (NaOH) with a long soaking time of 2 hours, the composition of the fiber versus resin (90%:10%, 85%:15% and 80%:20%) and the direction of the fiber arrangement (0 °, 45 ° and 90 °) as reinforcement. The composite was tested for tensile strength to identify the quality of the pineapple leaf fiber composite and analyzed for the effect of fiber composition versus resin and the effect of variations in the direction of fiber composition on tensile strength. The results of the research carried out found that the factors that greatly influenced the tensile strength were in the variation of the arrangement of the fiber directions, the average value of the tensile test was 45.79 MPa and the average value of the S/N Ratio was 19.44. The results of the calculations carried out obtained the optimal level setting A1 (90%: 10%) and B1 (0 °) the average value of the tensile test was 54.19 MPa and the average value of the S/N Ratio was 34.68. The results of the verification test of the parameters and levels (A1 and B1) obtained a value that is not much different from the previous value, there is a tensile test value of 54.48 MPa and an S/N Ratio value of 34.72.
