Telah dilakukan penelitian untuk menganalisis morfologi selulosa kristalin hasil sintesis dari serbuk gergajikayu belian (Eusideroxylon Zwageri). Selulosa kristalin diperoleh melalui proses ekstraksi, bleaching danhidrolisis. Proses hidrolisis disertai dengan sonifikasi dan sentrifugasi dengan memvariasikan kelajuansentrifugasi adalah untuk mempelajari pengaruh kelajuan sentrifugasi terhadap ukuran kristalin yangterbentuk. Berdasarkan analisis SEM, morfologi selulosa kristalin yang dihasilkan berupa fiber denganukuran partikel rerata adalah 14,27 μm untuk kelajuan sentrifugasi 3.500 rpm dan 13,71 μm untukkelajuan sentrifugasi 4.500 rpm.
