Abstract

Fish waste contain various nutrients which are: N (Nitrogen), P (phosphorus), K (Potassium) which is a constituent component of organic fertilizer. With the hydrolysis process, processed fish waste into organic fertilizer with a high concentration. The content of bromelain in pineapple fruit is one type of enzyme sulfhydryl protease that is able to hydrolyze peptide bonds in a protein or polypeptide into smaller molecules of amino acids. This research aims to produce organic fertilizers that contain various nutrients that plants need, to overcome shortages of fertilizer, supporting the Government's program "Go Organic 2010". Variables that performed in this study is the concentration of enzyme, and hydrolysis time. And the best results take place on condition: nutrients Nitrogen (N) at 40% enzyme concentration, hydrolysis time of 10 hours with levels of 48.021%; nutrient phosphorus (P) at 60% enzyme concentration, hydrolysis time of 4 hours with 17.886% and the nutrient levels of Potassium (K) at 60% enzyme concentration, hydrolysis time of 8 hours with levels of 16.14%
