Quality of Physical and Chemical Properties of Liquid Organic Fertilizer from Tofu Liquid Waste with Banana Hump Mol Decomposer

: Liquid organic fertilizer is a fertilizer that is available in liquid form. This liquid organic fertilizer can be made naturally through a fermentation process to produce a solution of decay from plant residues. Liquid organic fertilizer is better to use because it is free from chemicals and has a good impact on health. The purpose of this research is to study the manufacturing technique and to determine the physical and chemical properties of liquid organic fertilizer from tofu liquid waste with banana hump mole decomposer. The research method is experimental. The results obtained are the quality of the physical properties of liquid organic fertilizer from tofu liquid waste with banana hump Mol with an average temperature from 26 to 29 o C, yellow (8/8) 10YR color or reddish yellow, characteristic sour smell, and TSS 5132 – 5879 mg L -1 . The quality of the chemical properties of liquid organic fertilizers are the average pH 3.62 – 3.72: Nitrogen 7.98 – 8.22%, Phosphor 0.002%, and Potassium 0.03%. The liquid organic fertilizer is under the standard of liquid organic fertilizer but the pH value is slightly lower than the standard.
