Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan serat ijuk terhadap sifat fisis dan mekanik papan komposit semen-gipsum. Penambahan serat ijuk yang digunakan untuk masing-masing sampel dengan perbandingan terhadap matriks semen dengan gipsum yaitu 0%, 2%, 4%, 6% dan 8%.  Pada penelitian digunakan jenis komposit laminat, yaitu komposit yang terdiri dari dua lapis atau lebih yang digabungkan menjadi satu dengan setiap lapisnya memiliki karakteristik tersendiri.  Dari pengujian yang telah dilakukan diperoleh hasil bahwa sifat fisis bahan yaitu densitas mengalami kenaikan sejalan dengan penambahan serat ijuk. Daya serap air mengalami penurunan sejalan dengan penambahan serat ijuk. Dari pengujian sifat mekanik untuk kuat tekan dan kuat lentur, persentase optimum penambahan serat ijuk adalah sebanyak 4% yang nilainya masing-masing adalah 123,87 kg/cm2 dan 40,83 kg/cm2. Dari keseluruhan pengujian, persentase penambahan serat ijuk terbaik terdapat pada komposisi serat ijuk 4%.
