Abstract: Organic fertilizer are fertilizer that work in increasing the biological, chemical and physical activities of the soil so that the soil becomes fertile and good for plant growth. Kersen leaves and eggshells are materials that can be used as liquid organic fertilizer because they contain various types of ions such as nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg) and calcium (Ca) ions. The production of liquid organic fertilizer is carried out using an anaerobic fermentation process. This study aims to obtain the optimum conditions for the volume of spoiled rice MOL bioactivator (30, 50, and 70 ml) and fermentation time (7, 12, and 18 days) to produce liquid organic fertilizer with the best quality. Parameters observed in the production of liquid organic fertilizer are nitrogen content, phosphorus content, potassium content (NPK), pH and color and scent. The results of the best quality liquid organic fertilizer were obtained in the 50 ml addition of spoiled rice MOL. The optimum fermentation time for nitrogen and potassium content was obtained on the 18th day, 0.01296% N and 0.2947% K2O, phosphorus content obtained on the 12th day is 0.8928% P2O5, with the pH value of 6, dark brown and odorless.
