Abstract
Abstract Organic liquid fertilizer is the result of decomposition of organic materials derived from plant residues, animal dung, and humans. One of the researches on making liquid fertilizer has been carried out by using the raw material of cherry leaves. It is known that the content of N; P; K liquid fertilizer from previous studies has not met the quality standard of the Ministry of Agriculture. To increase the content of liquid fertilizer cherry leaves we add rabbit dung and EM4 as raw material in addition to cherry leaves. The making of liquid fertilizer uses fermentation and extraction technology with anaerobic process. The results of this study showed that the content of N, P, K of liquid fertilizer leaves of cherry fertilizer with the addition of rabbit droppings and EM4 increased compared to the liquid leaves of cherry fertilizers from previous studies. The best quality liquid fertilizer is produced on day 25 with a weight / solvent ratio (300 grams of cherry leaves + 250 gr rabbit droppings) / 1500 ml of water with an ion concentration of N = 1.41%; P = 1.141%; K = 2.21% Key word : Cherry leaves , Extraktion,Fermentation,rabbit droppings.
