  An experiment was conducted for the evaluation of Palm Kernel Cake Fermented (PKCF) by Aspergillus niger as a substitute for soybean meal protein in the diet of broiler. The experiment used a Complete Randomize Design (CRD) with 6 treatments and 4 replications. The treatments were arranged as follows: 1) 0% basic ration (0% PKCF), 2) 20% substitution of soybean meal protein with PKCF, 3) 40% substitution of soybean meal protein with PKCF, 4) 60% substitution of soybean meal protein with PKCF, 5) 80% substitution of soybean meal with PKCF, 6) 100% substitution of soybean meal with PKCF. The ration were formulated in iso protein 22% and iso caloric 3000 k cal/kg ration. This study used a completely randomized design with six treatments and four replications. The parameters of this study were feed consumption, body weight gained, feed conversion and percentage of carcass. The result of this study showed that feed consumption, body weight gained, feed conversion and percentage of carcase were not significantly affected (p>0.05) by any treatment. In conclusion the Palm Kernel Cake Fermented (PKCF) by Aspergillus niger can be 100% a substitute of soybean meal protein or 17% in broiler ration.

  An experiment was conducted to improve the nutrient content of tapioca by-products (onggok) through fermentation by using cellulolytic bacteria (Bacillus amyloliquefaciens) as inoculums. The experiment was determination of the optimum conditions (dosage of inoculums, fermentation length and temperature) for tapioca by-products (onggok) fermentation based on nutrient quality and quantity of these fermented products. The study was conducted in experimental methods, using the completely randomize design in factorial with 3 treatment were: 1) A factor (Dosage of inoculums: A1 = 2%, A2 = 6%, A3 = !0%), 2) B factor (Fermentation length: B1 = 3 days, B2 = 6 days, B3 = 9 days) and 3) C factor (Temperature: C1 = 30oC, C2 = 40oC, C3 = 50oC). Results of study showed that optimum conditions of the fermentation of tapioca by-products (onggok) was at 2% dosage of inoculums, 6 days of fermentation length and 40oC temperature. This conditions can decrease 32% of crude fiber and increase 360% of crude protein which made the nutritional value of the product based on dry-substance was 7.9% crude protein, 2.75% crude fat, 11.55% crude fiber, 0.26% calcium, 0.17% phosphor, 2190 Kcal/kg metabolic energy and 65.95% nitrogen retention.

  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 (p<0.01). Humic acid dosage were not (p>0.05) effected to dry matter, but against crude protein and crude fiber, there were significant (p<0.01) effect. Fermented time showed that there were highly significant (p<0.01) effect to dry matter, crude protein and crude fiber. The conclusion was palm kernel cake which was fermented by Aspergilus 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%.
