This study aimed to produce ruminant feed pellets using Indigofera zollingeriana as the main ingredient, along with coconut pulp, rice bran, molasses, cassava, and EM 4 as additional components. The objective was to investigate the impact of optimizing animal feed pellets made from Indigofera zollingeriana and various mixed ingredients, such as rice bran, coconut pulp, cassava, molasses, and EM 4, by using the EM 4 fermentation method on the physical, mechanical, and chemical properties of the animal feed pellets. The animal feed was prepared by blending Indigofera zollingeriana, coconut pulp, rice bran, and cassava in the proportion of (55.81% : 22.1% : 14.73% : 7.365%), along with molasses and EM 4 in a 1:1 ratio. The test samples were produced by weighing, pulverizing, mixing, fermenting, drying, and molding into pellets. The findings showed that the animal feed pellets made with Indigofera zollingeriana plant concentrate had physical properties that did not meet the standard values, such as specific gravity (1.96 gr/mL), porosity (8.84%), water absorption (68.76%), maturity temperature (38ºC), and solubility in water (4.36%). However, the animal feed pellets had a brownish color and a normal smell, similar to other animal feeds. In terms of mechanical properties, the values for hardness (5.002%) and brittleness (1.53%) met the standard values for animal feed pellets. Regarding chemical properties based on proximate analysis, the animal feed contained 8.22% protein, 6.78% total fat, 26.4% crude fiber, 17.4% carbohydrates, 7.50% ash content, and 33.7% moisture content. Only the ash content met the SNI 3148-2:2017 standard. Thus, the quality of these animal feed pellets needs improvement.

The purpose of this study was to determine the effect of the addition of cassava as an adhesive and the use of palm kernel meal as a concentrate and the addition of other ingredients on the physical, mechanical and chemical properties of food ingredients in the form of pellets. The animal feed was made by mixing palm kernel meal, tofu dregs, rice bran, and cassava with a percentage of (68,5 : 15,75 : 5,25 : 10,5)% and mixing molasses and EM 4 in a ration 1 : 1. The test samples were made by going through the stages of weighing, chopping, mixing, fermentation, drying, and molding into pellets. The results showed that the animal feed mixture had a specific gravity of 1.70 gr/mL, porosity of 29.05%, water absorption of 72.62%, pellet hardness of 4.85%, and brittleness with 4.92%. Animal feed pellets have a brownish color and a normal smell like the smell of animal feed pellets in general. The fermentation process was carried out for 8 days until it reached a maturity temperature of 38.44°C. Based on the proximate analysis, it was found that the animal feed contained 10.50% protein, 2.30% total fat, 22.80% crude fiber, 28.50% carbohydrate, 3.00% ash content and 32.90% moisture content. This animal feed pellet with palm kernel meal concentrate and cassava adhesive can be used as an alternative to cattle feed as an energy source feed, because it has a protein content of less than 20%.
