Summary:The biomass of rattan is one of natural waste that contains 37.6% of cellulose contents, which is potential to become a source of nanocrystalline cellulose as a filler in biocomposites. There are three important steps to produce alpha cellulose: delignification, alkalization, and bleaching. Nanocrystalline cellulose was extracted through the hydrolysis of alpha cellulose by using sulfuric acid and followed by ultrasonication, centrifugation, and filtration steps. Sago starch biocomposite has been made by casting method. The tensile properties of biocomposite were analyzed and the characterization was done by scanning electron microscopy (SEM). Results have shown that nanocrystalline cellulose has made a strong interfacial interaction with starch that can be improved the tensile strength of biocomposites. SEM have shown smoother and more coherent surface and supported the tensile properties result.
