Abstract

Telah dilakukan penelitian tentang karakterisasi sifat mekanik dan biodegradable komposit hibrid polipropilena dengan pati singkong menggunakan serat pinang dan serat eceng gondok. Penelitian ini bertujuan untuk menghasilkan komposit hibrid yang kuat dan ramah lingkungan  Komposisi serat pinang dan eceng gondok divariasikan dengan rasio perbandingan 1:1. Persen volume serat yang digunakan yaitu 5%, 10%, 15%, 20%,  dengan panjang serat 3 mm. Pembuatan sampel pada penelitian ini menggunakan metode hand lay-up. Metode hand lay-up merupakan proses pelapisan serat dengan matrik yang dilakukan secara manual. Penelitian ini dilakukan pengujian kuat tarik, regangan, modulus elastisitas dan uji biodegradable. Berdasarkan hasil penelitian didapatkan nilai kuat tarik dan modulus elastisitas tertinggi yaitu 18,37 Mpa dan 3549 Mpa pada fraksi volume serat 5%. Nilai regangan tertinggi yaitu 0,0064 % pada fraksi volume serat 20%. Pada laju degradasi didapatkan hasil sebesar 0,03853% per hari. Maka dari hasil penelitian dapat disimpulkan nilai modulus elastisitas sudah memenuhi standar dashboard mobil.

Abstract

The impact strength and density characterization of hybrid composites with polypropylene - cassava starch matrix using areca nut fiber and water hyacinth fiber has been carried out. The purpose of this study is to obtain superior and environmentally friendly hybrid composites. The ratio of areca nut fiber and water hyacinth is 1:1 while the matrix composition is polypropylene, sorbitol and cassava starch is varied with a ratio of 8:1:1. The percentage of fiber used in each sample is 5%, 10%, 15%, 20% while the percentage of matrix used is 95%, 90%, 85%, 80%. The tests carried out are impact strength and density. Based on the results of the study, the highest impact strength value is 0.0624 J / mm2 found in the 5% fiber volume fraction. The highest density value is 0.844 g / cm2 found in the 5% fiber volume fraction. Therefore, from the research results, it can be concluded that the impact strength value meets the car dashboard standards and the density value obtained is included in the type of particle board with medium density.
