The study aims to determine the effect of liquid organic fertilizer (LOF) to increase the production of soybean. The experiment was carried out using a one-factor randomized group design (RGD) with three replications. The LOF was generated from several types of organic waste, including water hyacinth, banana root, fishbone and chickenâs eggshell. The treatments were divided into, M0= without LOF (control), M1= LOF water hyacinth, M2= water hyacinth + banana root; M3= water hyacinth + fishbone; M4 = water hyacinth + chicken eggshell; M5= water hyacinth + banana root + fishbone; M6= water hyacinth + banana root + chicken eggshell; M7= water hyacinth + fish bone + chicken eggshell, and M8= water hyacinth + banana root + fish bone + chicken eggshell. The data were analyzed using analysis of variance. The result showed that all types of LOF formulation could be used as soybean fertilizer, especially on the increasing of soybean pods formation, average volume and weight of dry soybean seeds, number of fertile pods, and decrease the empty pods formation compared to the control (p < 0.05). Further analysis showed that the soybean fields could produce the produce from 3.22 tons/ha â 3.99 tons/ha, and it was 42.5% higher than the control that only produce 1.87 tons/ha. In the future, the organic waste processing into the LOF could be used to increase the land productivity, prevent land degradation, as well as strive to be a solution in overcoming the organic waste issue.
