Pembuatan Papan Partikel Berbahan Dasar Sabut Kelapa (Cocos nucifera L.)

Abstract

LISBETH DAMERIAHNI SIJABAT : Manufacture of particle board made from coconut fiber, supervised by AINUN ROHANAH, ADIAN RINDANG and RUDI HARTONO. Coconut fiber is howaste which has high cellulose that can be used as a raw material for particle board. This study was aimed to determine the effect of concentration of isocyanate adhesive to the physical and mechanical properties of particle board as well as to determine the optimal level of adhesive in the manufacture of particle board from coconut fiber (Cocos nucifera L.). Particel board was made with a dimension of 1 cm x 25 cm x 25 cm, with density of 0,7g/cm3. Variant in this study is isocyanates 5, 7, dan 9%. Parameters measured were density, moisture content, swelling thickness, DSA, Modulus of Rupture and Modulus of Elasticity of the particle board. The results will determine with SNI 03-2105-2006 standart. The results showed that the value of physical properties of particle board made from coconut fiber are density, moisture content,and thickness swelling during 2 hours were comply with the SNI 03-2105-2006, while on swelling thickness during 24 hours only the 9% isocyanates comply with the standart. In the case of mechanical properties of the particle board, only modulus of rupture comply with the standart and the value of modulus of elasticity not comply the SNI 03-2105-2006 standard. Optimal levels in this adhesive study was 9% isocyanates content.
