ABSTRACT
Solid organic fertilizer is the result of composting from the remaining agricultural and livestock waste, which contains macro and micro nutrients so that it can improve soil structure. This study aims to study the effect of composting time and EM4 concentration on the organic fertilizer produced and to analyze the N, P, K content of the solid organic fertilizer produced. Fertilizer is made by composting materials such as rice straw charcoal, livestock manure and rice husk in a ratio of 3:1:1 with additions EM4 bioactivator. Composting was carried out with variations in the length of fermentation time to 14; 21; and 28 days, and variations in the concentration of EM4 to 30%; 40%; and 50%. The largest Nitrogen (N) content was obtained on day 28 with a 30% EM4 concentration of 1.61%, and the largest Phosphorus (P) level was obtained on day 28 with a 40% EM4 concentration of 0.97%, while Potassium (K) was greatest on day 28 with a 30% EM4 concentration of 1.30%. The longer the composting time, the higher the levels of Nitrogen (N), Phosphorus (P) and Potassium (K) in the fertilizer produced. While the EM4 concentration did not significantly affect the levels of Nitrogen (N), Phosphorus (P) and Potassium (K) in the fertilizer produced.
Keywords: Effective microorganism 4, rice straw, compost, organic fertilizer, composting
