Abstract:
An experiment was conducted to improve the nutrient content of palm kernel cake through fermentation by Aspergillus niger with combination humid acid dosage and fermented time. The experiment used Complete Randomize Design (CRD) with 3 x 3 factorial and twice replication. The first factor was humic acid dosage: (1) 0 ppm, (2) 100 ppm and (3) 200 ppm. The second factor was fermented time: (1) 5 day, (2) 7 day and (3) 9 day. The parameters were dry matter, crude protein and crude fiber. The result of study showed that there was no significantly (p>0.05) interaction between humic acid dosage and fermented time to dry matter, but against crude protein and crude fiber, there were highly significant interaction (p0.05) effected to dry matter, but against crude protein and crude fiber, there were significant (pAspergilus niger showed that humic acid 100 ppm and fermented time 7 day had a better content. This condition can be seen in crude protein 23,20%, crude fiber 10,59% and dry matter 42.38%.
