Studi Pembuatan Pupuk Organik Cair dari Fermentasi Urine Sapi (Ferisa) dengan Variasi Lokasi Peternakan yang Berbeda

Abstract

Abstract. Place of raising animals is a place that produces waste in the form of feces, urine, and water washing. One of the potential waste to be used is cow urine. The content of urine has the potential to be used as fertilizer. Fertilizers that are potentially to be made is a liquid organic fertilizer. One technique of liquid organic fertilizer is a fermentation technique. The media used is a bacterial activator Agri Simba with the addition of Molasse. In this study, used four variations of cow urine taken from areas representing the upstream-downstream regions, namely Dhusun Thekelan, Desa Sumur Jurang, Jatibarang and Desa Tambak Mulyo to know the nutrients in each of the urine. In addition to determine the effect of long fermentation on the content of macro nutrients found in urine is used each time variation of 0, 3, 6, 9, 12, and 15 days. The results obtained in the initial content of urine has the potential to be used as liquid organic fertilizer. Long fermentation affect the increased element of Nitrogen, Phosphorus and Kalium, but resulted in a decrease in C-organic elements. Improved elements nitrogen, phosphorus, and kaium vary in each type of urine, which is about the optimum time of fermentation. While the best fertilizer to use is an organic liquid fertilizer from fermented cow urine coming from the Desa Tambak Mulyo which have C / N ratio is lowest. Key words: Liquid Organic Fertilizer, cow urine, Elements of macro nutrients, the optimum fermentation time.
