Abstract

Composite materials with natural fiber filler have widely known in the manufacturing industry. Environmentally friendly material, which is able to be recycled, and can be destroyed itself by nature is a requirement of today's technology. Coco fiber is a natural fiber derived from the processing of coconut wastes that are abundant in the Moluccas and has not utilized optimally. A research are conducted with focus on getting the maximum value of volume variation fraction of coco fiber to the value of bending strength and impact strength, in accordance with the desired application. This research uses Hands Lay Up method in manufacturing the fiber composite sole with a variation of the volume fraction of coconut fiber 90%: 10%, 80%: 20%, 70%: 30%, 60%: 40%, 50%: 50%. The dependent variable is strength bending and impact strength. Results show that an increase in bending strength and impact strength with escalation of volume fraction. The highest bending strength of coco fiber composite is obtained at fraction volume 40% (90 709 MPa), the bending strength lowest at fraction volume 10% (66 520 MPa), Price Impact highest at fraction volume 50% (0203 J / mm2) and the lowest in fraction volume 10% (0.041 J/mm2).

Abstract

Material komposit dengan filler serat alam mulai banyak di kenal dalam industry manufaktur. Material yang ramah lingkungan, mampu di daur ulang, serta mampu dihancurkan sendiri oleh alam merupakan tuntutan teknologi sekarang ini. Serat ampas empulur sagu adalah serat alam yang berasal dari limbah hasil pengolahan pohon sagu yang berlimpah di daerah Maluku dan belum termanfaatkan secara optimal. Penelitian ini dititikberatkan untuk mendapatkan nilai maksimal variasi fraksi volume serat ampas empulur sagu terhadap nilai kekuatan bending dan kekuatan impak, sesuai dengan aplikasi yang diinginkan. Penelitian menggunakan metode Hands Lay Up, dalam pembuatan komposit serat tunggal dengan variasifraksi volume serat ampas empulur sagu 10%, 20%, 30%, 40%, 50%, dan model RAL dan uji Tukey untuk menentukan fraksi volume (perlakuan) terbaik bagi komposit tersebut. Variable terikat dalam penelitian adalah Kekuatan Bending dan Kekuatan Impak. Hasil penelitian memberikan kesimpulan bahwa kendati terjadi kenaikan kekuatan bending dan kekuatan impak seiring penambahan fraksi volume, namun hanya fraksi volume 0,3 dan 0,4 yang secara simultan memiliki sifat Kekuatan Bending dan Kekuatan Impak yang lebih baik
