Ekstraksi Selulosa Dari Serbuk Gergaji Kayu Sengon Melalui Proses Delignifikasi Alkali Ultrasonik

Abstract: ABSTRAK EKSTRAKSI SELULOSA DARI SERBUK GERGAJI KAYU SENGON MELALUI PROSES DELIGNIFIKASI ALKALI ULTRASONIK. Kayu sengon (Albizia chinensis) merupakan salah satu jenis kayu yang melimpah di Indonesia. Kandungan selulosa pada kayu sengon cukup tinggi sebesar 41,17 %. Proses ekstraksi selulosa dari kayu sengon dapat dilakukan melalui proses delignifikasi atau penghilangan kandungan lignin. Umumnya, proses delignifikasi dilakukan dengan larutan alkali pada konsentrasi tinggi, suhu tinggi dan waktu yang lama. Agar k… Show more

“…Figure 4 shows the morphology of the SEM test results for the CNC-45% sample, which is relatively similar to the morphology of sengon wood (Trisanti et al, 2018). SEM test results show that the grain distribution structure is Anggraini A, Manurung P, Suciyati SW, Yulianti Y, 2023, Extraction of Nanocellulose from Softwood Pine (Pinus merkusii) Using Acid Hydrolysis Method, Journal of Energy, Material and Instrumentation Technology, Vol.…”

“…Cellulose isolation has been carried out from banana stem waste with delignification process using NaOH and bleaching with NaOCl. Lignin and hemicellulose ester bonds and glycosidic bonds in lignocellulose can be broken down by alkaline [17]. Delignified sample was obtained as a brown viscous solution.…”

“…Adanya bakteri yang mampu tumbuh pada medium ini menunjukkan bahwa bakteri tersebut mempunyai kemampuan menguraikan selulosa, sebab dalam medium enrichment yang digunakan sumber karbon satu-satunya adalah selulosa. Dengan demikian dapat diasumsikan bahwa bakteri yang tumbuh pada medium enrichment tersebut adalah bakteri pendegradasi selulosa [13].…”
