Abstract

Telah dilakukan penelitian mengenai pengaruh persentase serat sabut kelapa dan foam agent terhadap sifat fisik dan mekanik papan beton. Variasi persentase serat 0%, 0,3%, 0,6%, 0,9% dan 1,2% menggunakan metode penyusunan serat secara acak. Sifat fisik dan mekanik yang diujikan meliputi densitas, daya serap air, porositas , kuat tekan dan kuat lentur. Penambahan serat sabut kelapa dan foam agent dapat membuat  papan beton menjadi lebih ringan dibandingkan dengan papan GRC yang beredar di pasaran.  Dari hasil pengujian didapatkan nilai densitas yang terendah diperoleh pada persentase serat sabut kelapa 0,9 %. Penambahan 0,9% serat sabut kelapa dan 0,6% foam agent  merupakan persentase optimum dalam pembuatan  papan beton.  Nilai densitas papan beton sudah memenuhi standar SNI 03-2105-2006 dan  nilai kuat tekan serta kuat lentur sudah memenuhi standar SNI 03-3449-2002.
