Abstract

Telah dilakukan penelitian tentang pengaruh persentase serat sabut pinang dan foam agent terhadap sifat fisik dan mekanik papan beton ringan. Penelitian ini menggunakan metode hand lay-up dengan memvariasikan persentase serat sabut pinang yaitu 0%; 0,2%; 0,4%; 0,6% dan 0,8%. Sifat fisik dan mekanik yang diujikan meliputi daya serap air, densitas, kuat tekan dan kuat lentur. Pengujian kuat tekan dan kuat lentur menggunakan universal testing machine (UTM). Hasil menunjukkan nilai daya serap air terendah diperoleh pada papan dengan persentase serat 0,8% yaitu 14,69%, sedangkan densitas terendah diperoleh pada persentase serat 0,6% sebesar 1,42 g/cm3. Nilai kuat lentur tertinggi diperoleh pada 0,4% serat yaitu 37,5 kgf/cm2. Kuat tekan tertinggi diperoleh pada pesentase serat 0,2% yaitu 54,87 kgf/cm2. Papan beton ringan serat sabut pinang dan foam agent memiliki sifat fisik lebih tinggi dibandingkan papan GRC.

Kata kunci: foam agent, hand lay-up, papan GRC serat sabut pinang.
