การพัฒนากระบวนการหมักหัวมันสำปะหลังเพื่อให้ได้โปรตีนเป็นส่วนผสมอาหารสัตว์

Abstract

This research aims to develop a fermentation process for agricultural products to produce sludge with enough crude protein and to use the analysis results to compare the amount of crude protein obtained from the method used as an ingredient in animal feed. The experiment was carried out with a factorial design and a completely randomized design (CRD) with two factors at two levels each (a x b factorial in CRD). The factors used in the process are freshly crushed cassava roots (A. a1, a2), 300 kilograms, and 300 kilograms of fresh crushed and fermented cassava roots covered for one month. Use the stirring motor at 100 rpm (B. b1, b2) with the second factor for 2 and 6 hours/day. Install a water pump to circulate water and sediment from the bottom of the fermentation tank to mix with the air sent back into the fermentation tank. Add 100 grams of naturally inoculated microorganisms to each tank and 10 kilograms of organic food supplements. Replicate four replicates (2²x4), and record the temperature (Temp), acid-base (pH), and oxygen (DO) every day until 30 days. After stopping the process for one month, filter to collect sediment from the bottom of the tank or float on the water's surface, then dry it under sunlight (solar drying). After the sediment has dried and the moisture is lower than 10%, grind it thoroughly, take a fine sediment sample, and send it for analysis to a certified laboratory to ascertain and certify the results of any level of protein composition. From the resulting data analyzed. It showed that the first factor used in the process (A, both a1 and a2) was the factor that affected the quantity of crude protein obtained from the process (p = 0.025), and in the statistical analysis to compare the average protein content obtained in each process and including those that did not go through the process (control). It was found that there were statistically significant differences (p = 0.000). It was found that the protein content from all four processes was at an appropriate level of nutrients and could be mixed into animal feed or fed to many types of animals including large and small animals, poultry, and aquatic animals.
