<![CDATA[The influence of the substitution of rice husk flour and cassava flour in industrial flour to the increase of plywood bonding strength. The research of the addition of rice hush flour to substitute industrial flour in plywood glueing has been done. A preliminary research has specified the property of industrial flour needed as an extender in a plywood glueing and the role of rice hush flour and cassava flour in that process. Some parameters such as the content of carbohydrate, lignin, moisture, particle size and ash had been tested. Theaim of this research is to substitute industrial flour with rice husk flour. Based on the previous research, cassava flour can substitute industrial flour with ratio 60 : 40 and 50 : 50. In this research, rice husk flour has been used to substitute the proportion of cassava flour in that two ratios above. Another inggridients in the used glueing formula were industrial flour, cassava flour, urea formaldehyde, hardener, and veneer from Meranti ( B1) and Kapur (B2). The result of this research shows that the content of lignin, cellulose and carbohydrate of rice husk was high enough to influence the process of plywood glueing. The result of all delamination testing were passed or 100% of all specimen passed delamination testing.]]>
