    Baby diaper contents cellulose pulp that can be used as substrat in cellulose production. The objective of this study was to investigate baby diaper biodegradation abilities of cellulolytic fungi Trichoderma asperellum T.N.J63 which isolated from orange farmland in Riau province. Biodegradation process by solid fermentation was carried out for 10, 15, 20, 25, and 30 days. Parameters examined were activity of crude extract cellulose using Nelson-Somogyi method, organic carbon (TOC) using gravimetric method, nitrogen total (N-total) using Kjedahl method, and C/N ratio. The result showed that baby diaper can be useed as substrat to produce cellulose. The highest activity of crude extract cellulose was found at 25 days fermentation by T.N.J63 LBKURCC2 (5,78± 0,37) × 10-3U/mL. Total organic carbon was decreased during 30 days fermentation (29.668%), N-total during 30 days fermentation (0.418%), and C/N ratio was found to be 106.351.
