Liquid organic fertilizer (POC) is an organic fertilizer produced from a fermentation process and contains nutrients needed for plant growth. This study aims to determine the POC nutrient content of several types of organic waste and its potential as a nutrient in a hydroponic system. This study used 4 types of organic waste, namely banana peels, orange peels, pineapple peels and cow urine and divided into 6 types of POC, namely POC banana peels (P1); POC orange peel (P2), POC pineapple skin (P3); POC of fermented cow urine with MOL of pineapple skin with a ratio of 5:1 (P4); POC of fermented cow urine with MOL of pineapple skin with a ratio of 2:1 (P5) and POC of fermented cow urine with MOL of pineapple skin with a ratio of 1:1 (rP6). Parameters observed with the content of nitrogen (N), phosphorus (P2O5), potassium (K20) and pH of the six types of POC. The results showed that the POC with the highest nitrogen content is P6 (0.35%), the highest phosphorus content is P3 (0.38%) and the highest potassium is P6 (1.85%). The pH value of liquid organic fertilizer is in accordance with the minimum technical standards for liquid organic fertilizer, but the POC whose pH value is suitable for use as a hydroponic nutrient are P4 and P6
