Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh komposisi partikel ampas tebu dan tempurung kelapa terhadap sifat fisis dan mekanis papan partikel. Dalam penelitian ini digunakan perbandingan komposisi bahan pengisi dengan jumlah perekat yang tetap. Variasi komposisi bahan yang digunakan partikel ampas tebu dan tempurung kelapa adalah 70:0%, 50:20%, 35:35%, 20:50%, 0:70%. Kadar perekat resin epoksi yang digunakan adalah 30%. Ukuran partikel yang digunakan adalah lolos ayakan 100 mesh. Parameter yang diukur adalah densitas, kadar air, daya serap air, Modulus of Elasticity (MOE) dan Modulus of Rupture (MOR). Hasil uji sifat fisis diperoleh nilai densitas terendah 0,94 g/cm3 pada komposisi 70%:0% dan densitas tertinggi 1,06 g/cm3 pada komposisi 0%:70%. Nilai kadar air papan terendah 0,91% pada komposisi 0%:70% dan nilai kadar air tertinggi 3,74% pada komposisi 70%:0%. Nilai daya serap air terendah 17,11% pada komposisi 50%:20% sedangkan nilai daya serap air tertinggi 31,77% pada komposisi 35%:35%. Hasil uji sifat mekanis diperoleh nilai MOE terendah didapat sebesar 833,17 kg/cm2 pada komposisi 70%:0% dan nilai MOE tertinggi sebesar 1960,75 kg/cm2 pada komposisi 35%:35%. Nilai MOR terendah 487,88 kg/cm2 pada komposisi 70%:0% sedangkan MOR tertinggi 1101,44 kg/cm2 pada komposisi 35%:35%. Hasil penelitian menunjukkan bahwa sifat fisis dan mekanis papan partikel yang didapatkan pada pengujian telah memenuhi standar mutu SNI 03-2105-2006 kecuali untuk pengujian densitas dan MOE. Berdasarkan persentase densitas papan partikel maka papan partikel yang dihasilkan termasuk jenis papan partikel berekerapatan tinggi.
