Kandungan Nitrogen Dan Kalium Pada Pupuk Organik Cair Kombinasi Kulit Pisang Dan Daun Lamtoro Dengan Variasi Penambahan Jerami Padi

Liquid organic fertilizer is a fertilizer in the form of a solution from the decomposition of organic materials. The combination of banana peel extract, lamtoro leaves and rice straw with the addition of EM4 bioactivator can be processed into liquid organic fertilizer which containing nitrogen and potassium. The purpose of this research is to know the ontent of nitrogen and potassium in liquid organic rtilizer that made from combination of banana peel and lamtoro leaves with variation of rice straw. The method of this research is Completely Randomized Design with two factors, namely factor 1: composition ratio (K) banana peel and lamtoro leaves extract (K1 = 100 ml: 200 ml, K2 = 150 ml: 150 ml, K3 = 200 ml: 100 ml) and factor 2: dose of rice straw (D) (D1 = 10%, D2 = 15%). The results showed that the highest nitrogen content was found in the K3D2 treatment is 0.09% and the lowest content in the K1D1 treatment is 0.06%. While the highest potassium content found in K3D2 treatment is 0.15% and the lowest content in treatment K1D1 is 0.09%
