Abstract

Feed efficiency plays a crucial role in livestock production, as feed accounts for the largest portion of total production costs. One potential way to reduce feed expenses is by utilizing agricultural by-products such as onggok (cassava residue), which is abundantly available and affordable. However, onggok has limitations in its use as animal feed due to its low protein content, high crude fiber, and the presence of anti-nutritional compounds such as cyanogenic glycosides. Fermentation is an effective method to improve the nutritional quality and physical characteristics of onggok, making it more suitable as a feed ingredient. This study aims to determine the effect of the duration of Onggok fermentation using probio on dry matter content (DM), pH value, and physical quality. This study used a completely randomized design (CRD). The treatment pattern was in accordance with the treatment, namely four treatments and each treatment was repeated three times. P0: Onggok fermentation using 0.4% probio for 0 days, P1: Onggok fermentation using 0.4% probio for 3 days, P2: Onggok fermentation using 0.4% probio for 6 days, P3: Onggok fermentation using 0.4% probio for 9 days. The variables observed were dry matter, pH value, aroma, color, and texture. The results showed that the average DM value was obtained by P0: 85.05%, P1: 82.14%, P2: 85.13%, and P3: 77.63%. The average pH value was P0: 5.3% P1: 4.6% P2: 5% P3: 3.6%. Descriptively, Onggok had a more sour aroma, the color changed to light brown, and the texture was softer than before fermentation. The study concluded that dry matter content, pH level, and changes in physical characteristics were all significantly influenced by the probio fermentation time of 0 to 9 days.

Abstract

Corn tumpi is a waste from threshing corn, has the potential as an alternative feed material but the high lignin and cellulose content inhibits digestion. The research aims to determine the effect of corn tumpi fermentation using two different types of probiotics EM4 and MA11 on lignin and cellulose content. The experimental desaign used was a Completely Randomized Design (CRD) with a one-way pattern with 3 types of treatments and 8 replications, with fermentation for 7 days. The treatments applied were T0: 250 grams of corn tumpi + 2 grams of urea + 5 cc molasses; T1: 250 grams of corn tumpi + 2% MA11 + 2 grams of urea + 5 cc molasses; and T2: 250 grams of corn tumpi + 2% EM4 + 2 grams of urea + 5 cc molasses. The results showed that the average cellulose content in P0 was 23.54%; P1 was 15.95% and P2 was 14.18%, while the average lignin content achieved by the P0 treatment was 23.54%; P1 was 18.09% and P2 was 18.63%. This research can be concluded that the use of probiotics MA-11 and EM4 in corn tumpi fermentation can reduce cellulose and lignin content very significantly (P < 0,01).
