Physicochemical Properties of Liquid Organic Fertilizer from a Mixture of Fish Waste and Coffee Grounds
Journal Title: International Journal of Multidisciplinary Research and Analysis - Year 2025, Vol 8, Issue 01
Abstract
Liquid fertilizer made from fish waste contains relatively high nutrients and effectively removes unpleasant odors during production. Coffee grounds are often used to remove unpleasant odors in rooms. This study aims to utilize coffee grounds to remove unpleasant odors in the production of liquid organic fertilizer from fish waste. The factorial experiment's first factor was the raw material for making liquid organic fertilizer (LOF), consisting of cow blood waste (P1) and fish waste (P2), while the second factor was the addition of coffee grounds at levels of 0% (K0), 10% (K1), 20% (K2), 30% (K3), and 40% (K4). The experiment was repeated three times using a completely randomized design (CRD). The results showed that adding coffee grounds at 20-30% of the total material could reduce the strong odor to a milder one, changing to a fermented smell at the end of the LOF production. Adding coffee grounds increased the macro and micronutrient content and reduced the C/N ratio in the resulting LOF. Adding 20-30% coffee grounds from the total raw materials is a solution to the problem of producing LOF from fish waste that remove unpleasant odors, while also utilizing coffee grounds that is usually discarded and can pollute the environment.
