PENGGUNAAN RAGI Saccharomyces cerevisiae PADA PEMBUATAN PUPUK ORGANIK CAIR DARI APU-APU (Pistia stratiotes L)
This study purpose to determine the nutrient content contained in a liquid organic fertilizer from apu-apu is based on the analysis results laboratorium. The treatment of different activators in the manufacturing of liquid organic fertilizer from apu-apu, with two standard of treatment that yeast activator (p1) and EM4 activator (p2). Yeast is able to decipher the organic materials in the manufacture of Liquid Organic fertilizer apu-apu, the value of as much nitrogen element content using EM4, but the element content of phosphorus and potassium lower. Results from the study showed that the content of nitrogen (N) liquid organic fertilizer (POC) of apu-apu with yeast activator (p1) 0.13% and 0.13% N in the POC with EM4 activator (p2). The content of phosphorus (P) on the POC of apu-apu with EM4 activator worth 0.0112% and 0.0038% P on the POC of apu-apu with an activator of yeast. The content of potassium (K) on the POC of apu-apu with EM4 activator worth 0.0055% and POC with yeast activator worth 0.0032%.
