The Making of Probiotic Using Corn as Growing Media and Micromineral as Additive

Abstract

The purpose of this study was to determine the growth of Trichodermasp. used corn as growing media with the addition of micromineral as a probiotic. This study was designed based on a completely randomized design with four treatments and six replications. The treatment used are P0 = corn media + Trichoderma sp., P1 = corn media + Trichoderma sp. + 1% premix, P2 = corn media + Trichoderma sp. + 2% premix, and P3 = corn media + Trichoderma sp. + 3% premix. Making probiotics used corn growing media with the addition of micromineral (premix) had no significant effect (P> 0.05) on the growth of Trichoderma sp. Spores, but the highest number of spores was treated with the addition of 1% premix (P1) with spores 2,12 × 1010 cfu / g media. The treatment without the addition of premix (P0) was treated with the least amount of spores compared to other treatments with a number of spores of 1.75 × 1010 cfu/g media. The degree of acidity (pH) of probiotics with the addition of micromineral (premix) had a significant effect (P <0.05) on probiotics without the addition of micromineral. It was concluded that the addition of micromineral (premix) could increase the growth of Trichoderma sp. but if were excessive it would reduce the growth of Trichoderma sp. Spores.
