PT. PG. Gorontalo is the largest sugar factory in Gorontalo province in which 10% of sugarcane waste is not utilized properly. In this study, the isolation and characterization of cellulose and α-cellulose from bagasse in the processing of alkali were 0.1M and 1.0M NaOH solution. The analysis method consisted of counterfeiting, dehemiselulose, delignification and bleaching of 10% H 2 O 2 and 1% MgSO 4 . The next step was purification of cellulose to α-cellulose. Cellulose content was 75%, α-cellulose 37.89%. The characterization of the physico-chemical properties of the product included density analysis, viscosity, 2.01% moisture content, 5.01% ash content, pH 7.7 solubility test in 1M HCl, HNO 3 1M, H 2 SO 4 0, 2M, Ba(OH) 2 0.5M, KOH 0.5M, CH 3 COOH 1M, NaOH 2M, NH 4 OH 1M. The IR α-cellulose spectrum showed the presence of –OH group at wave number 3419, 3331, 3344, 3360 cm-1. The C-O bond at 1635 cm-1, 1642-1649 cm-1 showed different C-O stretch vibrations in cellulose I and cellulose II fibers and C-O bonds in 1161.83 and 1063-1065 cm-1, 995-895 cm-1 showed a change in the residual l about the glycosidic bond to Cellulose II which interprets α-cellulose. Morphological analysis used SEM while the degree of crystallinity used Diffractogram XRD.
