Utilization of cow urine waste for the manufacture of urine as a form of environmentally friendly dairy farming business

Abstract

Bio urine is a liquid organic fertilizer that comes from processing livestock waste. Bio urine is very useful and valuable. Processing of urine waste into Bio urine is one of the steps to overcome the problem of environmental pollution caused by the livestock sector. This study aims to determine the quality of Bio urine derived from local microorganisms (MOL) of animal, vegetable and liquid organic fertilizers which were seen from microbiological elements and Fe levels, so that they can be used as environmentally friendly organic fertilizers. Animal mole is made from rumen contents, molasses and water, then fermented aerobically for 14 days. Indigenous microorganism (IMO) from nabati is made from tomato waste, brown sugar, rice washing water, coconut water and fermented with the same aerobic system for 14 days. The research method used a randomized block design with 5 treatments, namely A+: Cow urine + EM4, A-: Cow urine only, B: Cow urine + 100% animal MOL, C: Cow urine + 100% vegetable MOL, D: Cow urine animal MOL 50%+ 100% vegetable MOL Cow Urine, each treatment was repeated 4 times. Parameters observed included pH, total microbial and Fe content. The results showed that the treatment had no significant effect on pH, total colonies and Fe levels, with the results of the study that cow urine added animal MOL, vegetable MOL and the combination gave a pH value of 8.43-9.98, total microbial log 72.363-80.333 and Fe content 0.0002-0.0007 ppm. The results showed that cow urine with the addition of Animal MOL, Vegetable MOL and the combination of the two did not give significantly different effects on P (phosphorus) content, N (Nitrogen) content, and K (Calcium) content.
