Abstract

Permintaan akan material yang ramah lingkungan dengan performa yang baik terus bertambah, khususnya di sektor industri teknologi dan otomotif. Penelitian ini bertujuan mengetahui pengaruh variasi komposisi serat bambu dan pelepah pisang terhadap kekuatan tarik komposit berbasis resin epoxy dengan orientasi serat 0°. Penelitian ini dilakukan secara eksperimental dengan metode hand lay-up disertai perlakuan alkali terhadap serat. Kemudian di uji tarik sesuai standar ASTM D638. Lima variasi komposisi digunakan dengan perbandingan resin 60% dan kombinasi serat bambu dan pisang. Hasil penelitian menunjukkan spesimen dengan komposisi 40% bambu 0% pisang memberikan kekuatan tarik sebesar 168 MPa. Sedangkan spesimen dengan dominasi kombinasi serat menunjukkan penurunan kekuatan tarik sebesar 113 MPa (20% bambu 20% pisang). Hasil pengamatan mikrostruktur mendukung data uji tarik, yang dimana distribusi serat yang merata dan minim void berkontribusi terhadap peningkatan kekuatan material. Berdasarkan hasil tersebut, serat bambu dan pisang dapat digunakan sebagai bahan alternatif komposit yang ekonomis dan ramah lingkungan. /*****/ The demand for environmentally friendly materials with good performance continues to grow, especially in the technology and automotive industry sectors. This study aims to determine the effect of variations in the composition of bamboo fiber and banana fronds on the tensile strength of composites based on epoxy resin with a fiber orientation of 0°. This research was carried out experimentally with the hand lay-up method accompanied by alkaline treatment of fibers. Then it is tensile tested according to ASTM D638 standard. Five variations of composition were used with a 60% resin ratio and a combination of bamboo and banana fibers. The results showed that the specimen with a composition of 40% bamboo and 0% banana gave a tensile strength of 168 MPa. Meanwhile, specimens with a predominance of fiber combinations showed a decrease in tensile strength of 113 MPa (20% bamboo, 20% banana). The results of the microstructure observations support the tensile test data, in which the even distribution of the fibers and minimal void contribute to the increase in material strength. Based on these results, bamboo and banana fibers can be used as alternative composite materials that are economical and environmentally friendly.
