The resource person for this activity was Mrs. Dra. Regina Tutik Padmaningrum, M.Si, who is a chemistry lecturer at FMIPA UNY and is competent in processing organic waste. The choice of this topic is based on the fact that household organic waste is usually just thrown away, even though if we look deeper organic waste can be used to be processed into various useful products, one of which is in the agricultural sector, namely it can be made into liquid fertilizer. In this training, Mrs. Regina said that liquid organic fertilizer has benefits, including encouraging and increasing the formation of leaf chlorophyll and the formation of root nodules in legume plants, thus increasing the photosynthetic ability of plants and absorbing nitrogen from the air, increasing plant vigor so that plants become sturdy and strong. , increases plant resistance to drought, weather stress, and attacks by disease-causing pathogens, stimulates the growth of production branches, increases the formation of flowers and fruit ovaries, reduces the fall of leaves, flowers and fruit ovaries
