Synthesis using a mixture of Coconut coir fiber and Terminalia catappa fruit fiber with the Polyvinyl Acetate (PVAc) matrix has been successfully carried out. The samples were made with variations in the composition of the volume fraction of Coconut coir fiber and Terminalia catappa fruit fiber, namely (0: 100), (30:70), (40:60), (50:50), (60:40), (70:30) ) and (100: 0)%. The ratio of the volume fraction of the mixture of natural fibers and the polyvinyl acetate (PVAc) matrix made was (70:30)%. The sample production begins with taking Coconut coir and Terminalia catappa fruit, drying and cutting, then mixing coconut coir and Terminalia catappa fruit fiber with a PVAc matrix, molding the composites using a press printing tool and drying. The finished sample is then physically tested by determining the density value and moisture content of the sample to see the quality of the sample. The results showed that the overall sample looked homogeneous, the density of the sample ranged from 0.52 to 0.72 grams/cm3 and the moisture content ranged from 10.05 to 12.89%. This means that the composite sample has met the SNI 03-02105-2006 criteria and is included in the medium density category.
