Abstract

Sugar cane bagasse is a by-product of the sugar industry which is the potential to be used as fish feed ingredient. However, high levels of lignin (20-35%) limit its potential utilization. Processing of bagasse as a fish feed ingredient requires a lignin degradation to reduce its levels. This study aims to degrade lignin in bagasse using a combination of techniques of microwave radiation and a strong alkaline solvent, NaOH. The treatments tested were NaOH solution with a concentration variant of 0.5 M; 1.0 M; 1.5 M and 2.0 M. Bagasse meal were added with NaOH solution 1/10 (w/v) then exposed to microwave radiation using 300 watts of power for 10 minutes. The parameters measured were lignin levels using the Chesson method and nutrient composition using the proximate method, before and after treatment. The results showed that 2.0 M NaOH was able to reduce lignin up to 6.85%, without having a negative effect on the nutrient content of bagasse. Thus, the treated bagasse is sufficient to be processed further to use as fish feed ingredient.
