MAKING LIQUID ORGANIC FERTILIZER WITH DIFFERENT FORMULATION FROM WASTE PATIN FISH INSTAL

Abstract

ABSTRACT

            Liquid organic fertilizer is a solution that comes from the decomposition of organic materials derived from plant residues, animal waste, and humans which contain more than one nutrient element. The purpose of this study was to determine the effect of fermentative microbes (EM4) and molasses with different formulations on the fermentation of catfish offal waste (Pangasius sp.) The research method was an experimental method, namely directly with a completely randomized design (CRD) non-factorial with the treatment namely addition of 0 ml (0%) EM4 + 60 ml (30%) Molasses (K1); 60 ml (30%) EM4 + 0 ml (0%) Molasses (K2); 40 ml (20%) EM4 + 40 ml (20%) Molasses (P1); 60 ml (30%) EM4 + 60 ml (30%) Molasses (P2);80 ml (40%) EM4 + 80 ml (40%) Molasses (P3). Parameters observed were pH, sensory form and the total number of lactic acid bacteria. Values that can be concluded the addition of fermentative microbes (EM4) and molasses with different formulations can be concluded that the best value of the length of fermentation is pH (Degree of Acidity) on day 14 with a sensory form of a white layer on the surface, a characteristic odor, and fertilizer that is suitable for use. The resulting product was brownish yellow and the best number of lactic acid bacteria in K2 treatment was 2,08 × 10⁴cfu/g.
