Abstract

Telah dilakukan penelitian tentang pengaruh persentase massa gipsum dan serat terhadap kuat tekan dan kuat lentur papan semen-gipsum berserat eceng gondok. Alat uji Kuat tekan dan kuat lentur  diukur menggunakan universal testing machine (UTM). Dari hasil pengujian terhadap papan semen-gipsum dengan persentase massa serat tetap 2,5% diperoleh nilai kuat tekan paling tinggi yaitu sebesar 14,52 kg/cm2 pada persentase massa gipsum 30%. Sedangkan pada papan semen-gipsum dengan persentase massa gipsum tetap 30% diperoleh nilai  kuat tekan tertinggi sebesar 24,99 kg/cm2 pada persentase massa serat 7,5%. Hasil pengujian terhadap papan semen-gipsum dengan persentase massa serat tetap 2,5% diperoleh nilai kuat lentur paling tinggi yaitu sebesar 1,265 kg/cm2 pada persentase massa gipsum 30%. Sedangkan pada papan semen-gipsum dengan persentase massa gipsum tetap 30% diperoleh nilai  lentur tertinggi sebesar 1,575 kg/cm2 pada persentase massa serat 5%.

Kata kunci: papan semen-gipsum, serat eceng gondok, kuat tekan dan kuat lentur.
