Widiyanto, Muhammad Galih (2019) Studi Pengaruh Fraksi Volume Bahan Dan Perlakuan Dengan Kalium Permanganat (Kmno4) Pada Serat Kenaf Terhadap Sifat Mekanik Komposit Sebagai Bahan Lambung Kapal. Sarjana thesis, Universitas Brawijaya.
Abstract
Penggunaan serat alam sebagai penguat komposit untuk material alternatif pada bahan lambung kapal baru tercapai untuk standar modulus elastisitas lentur Biro Klasifikasi Indonesia (BKI). Penelitian ini bertujuan untuk meneliti pengaruh fraksi volume filler serat kenaf dan matriks resin epoksi; serta penambahan perlakuan alkalisasi Kalium Permanganat (KMnO4) sebanyak 3 % dalam waktu perendaman 30 menit untuk memodifikasi permukaan serat dan meningkatkan sifat mekanik dari komposit agar dicapai standar BKI aplikasi bahan lambung kapal. Pembuatan komposit dilakukan dengan metode hand lay-up dan diuji untuk pengujian tarik serat tunggal; serta tarik dan lentur untuk komposit. Pengujian dilakukan untuk komposit dengan filler yang diberikan perlakuan KMnO4 dan komposit dengan filler yang tanpa diberikan perlakuan; dengan penggunaan tujuh variasi fraksi volume filler:matriks untuk masing-masing jenis komposit yaitu 50:50, 52:48, 54:46, 56:44, 58:42, 60:40, dan 62:38. Hasil yang didapatkan berupa nilai kekuatan tarik, modulus elastisitas, kuat lentur dan modulus elastisitas lentur tertinggi pada sampel komposit dengan filler yang tanpa diberikan perlakuan berturut-turut sebesar (57,43 ± 8,37) MPa; (2171,83 ± 316,97) GPa; (112,75 ± 16,88) MPa, dan (3952,31 ± 635,52) GPa. Komposit dengan filler yang diberikan perlakuan KMnO4 memiliki nilai kekuatan tarik, modulus elastisitas, kuat lentur dan modulus elastisitas lentur tertinggi berturut-turut sebesar (29,66 ± 3,07) MPa; (968,03 ± 108,71) GPa; (99,91 ± 6,69) MPa; dan (4928,58 ± 653,71) GPa. Namun, hasil dari kedua jenis komposit yang telah dibuat menunjukkan sifat mekanik yang belum mencukupi standar BKI.
English Abstract
The utilization of natural fiber from previous study for the usage of alternative material in the ship hull was newly accomplished for the standard modulus of elasticity of Biro Klasifikasi Indonesia (BKI). The purpose of this study is to examine the influence of volume fraction of kenaf fiber (Hibiscus Cannabinus L.) as a filler and epoxy resin as a matrix; and the addition of 3% alkalization treatment of Potassium Permanganate (KMnO4) in 30 minutes immersion time to modify the fiber surface and increase the mechanical characteristics of the composite in order to reach the BKI standard for application of ship hull material. The fabrication of the composite is done by the hand lay-up method, and is tested by tensile testing for single fibers; as well as tensile and bending for composites. The testing is carried out for composites with fillers treated with KMnO4 and composites with fillers without treatment; using seven variations in filler:matrix volume fraction for each type of composite which are 50:50, 52:48, 54:46, 56:44, 58:42, 60:40, and 62:38. The results of the highest tensile strength, modulus of elasticity, bending strength, and modulus of bending elasticity in composite samples with fillers without treatment are (57.43 ± 8.37) MPa respectively; (2171.83 ± 316.97) GPa; (112.75 ± 16.88) MPa, and (3952.31 ± 635.52) GPa. Composites with fillers that were immersed in KMnO4 had a result of the highest tensile strength, modulus of elasticity, bending strength, and modulus of bending elasticity in composite samples with fillers without treatment are (29.66 ± 3.07) MPa respectively; (968.03 ± 108.71) GPa; (99,91 ± 6,69) MPa; and (4928,58 ± 653,71) GPa. However, both types of composites that have been made produce mechanical characteristics that are not sufficient enough for BKI standard.
