Ketahanan Papan Komposit dari Pelepah Sagu (Metroxylon sago Rottb.) terhadap Jamur Pelapuk dan Rayap Tanah

Deni Zulfiana, Sukma S Kusumah

Abstract


Penelitian ini bertujuan untuk menguji ketahanan papan komposit dari pelepah sagu menggunakan perekat polyurethane (PU)dan phenol formaldehyde (PF) terhadap jamur pelapuk dan rayap. Ukuran dan target kerapatan papan komposit adalah 30x30x1 cm3 dan 0,5 g cm-3. Papan komposit dibuat dari susunan pelepah sagu yang dikempa dingin untuk papan komposit menggunakan perekat PU dan kempa panas untuk papan yang menggunakan perekat PF dengan tekanan spesifik 25 kg cm-2 selama 24 jam untuk kempa dingin dan 10 menit untuk kempa panas pada suhu 140 °C. Kadar padatan dari perekat cair adalah 50% dengan variasi kadar perekat yang digunakan dalam penelitian ini yaitu 10%, 12% dan 14%. Pengujian berdasarkan standar JIS K 1571 2004. Berdasarkan persentase kehilangan berat, papan komposit menggunakan perekat PU (polyurethane) dan PF (phenol formaldehyde) tidak tahan serangan jamur pelapuk dan rayap.
