The objective of this was to utilization researched palm kernel shell from the matrix using tapioca glue as an alternative raw materials in manufactured of composite boards. This researched to knew characteristic of influence matrix and filler composition percentage in physics and mechanics of composite board. Physics characteristic of a composite such as the density, water content, water absorption and thickness swelling whereas the characteristic of mechanic was compressive strength test. The composition of the matrix and filler roomates used was 50%: 50%; 40%: 60% and 30%: 70% and compression at 5 MPa of pressure. The highest density was shown 0.844 g / cm 3 in the mixture of composition 30% matrix and filler 70%. The Lowest water content was shown 12.14% in the mixture of composition 30% and 70% filler matrix. The Lowest water absorption for 2 hours water immersion was 6.74% in the mixture of composition 30% and 50% filler matrix whereas the water immersion for 24 hours was shown 47.2% in the composition of 30% and 70% filler. The thickness swelling for 2 hours water immersion Obtained result the Lowest 18% in the omposition 30% and 50% filler matrix whereas immersion for 24 hours was shown 121% in the composition of 30% and 70% filler. The highest compressive strength for palm kernel shell composite at 0.707 MPa was shown in the matrix composition of 30% and 70% filler. The density and water content were have had complies with the requirements of JIS A 5908-1994 for particle boards. Keywords: composite, palm kernel shells, tapioca glue, physics and mechanic characteristics.
