Abstract

This study discusses the fermentation of cow urine into bio urine. The purpose of this study was to optimize the fermentation process of bio urine from cow urine by giving starter bio urine. This study used a Completely Randomized Design with four treatments and three repeat. The treatment were without starter bio urine, 10 percent starter bio urine, 20 percent starter bio urine, and 30 percent starter bio urine. Each treatment was giving 1 liters molasses and 1 aerator. The observed variables were the degree of acidity (pH), biochemical oxygen demand, total dissolved solids, electrical conductivity, organic carbon, and nitrogen. The result of this study was the addition of starter no significant effect on the fermentation process of cow urine. But the process of cow urine fermentation can be accelerated from 15 days to 6 days. This is marked by the value of biochemical oxygen demand which has decreased on the 6 day of fermentation. Fermentation result was according on the standard No.70/Permentan/SR.140/10/2011. Of the four treatments in the process of cow urine fermentation, the treatment with no starter of bio urine was the best treatment, the treatment produce electrical conductivity 5622 mS, biochemical oxygen demand 3.3 mg/l, total dissolved sol ids 2811 ppm, acidity pH 5.77, organic carbon 3.77 percent, nitrogen 0.14 percent and C/N ratio 26,93. However, for the nitrogen content of bio urine not enough to meet the Permenta standard was 3-6 percen.
