PERBANDINGAN PERSEN VOLUME LIMBAH CAIR KELUARAN DIGESTER SEDIMENTASI DAN FERMENTASI BIOGAS UNTUK PEMBUATAN PUPUK ORGANIK CAIR

Palm oil mill effluent can pollute the waters because of high organic matter content, low acidity levels, and contain macro nutrients such as nitrogen (N), phosphorus (P) and potassium (K) that need treatment before being discharged to the river. Palm oil mill effluent when processed exactly it will produce biogas. Palm oil mill effluent is processed into biogas will produce liquid waste output sedimentation and fermentation biogas digester. This study aims to determine the exact volume percent ratio of output sedimentation and fermentation biogas digester for liquid organic fertilizer manufacturing process. The method used is an advanced anaerobic fermentation process of the two outputs of the biogas digester. Variables measured is the ratio of liquid waste volume percent of the output of biogas and bio-activator additions. The results showed that the highest nitrogen produced at 2.6625%, 0.0701% of phosphorus and potassium at 1.1055%. for liquid organic fertilizer with the addition of bio-activator. As for the liquid organic fertilizer without the addition of bio-activator, nitrogen is the highest of 2.4373%, 0.0689% phosphorus, and potassium 1.0335%. The nutrient content contained in the sample by comparison percent volume that contains the output digester sedimentation
