Abstract
Liquid waste of palm tree factory after the formation of biogas will produce side product of digester output whose characteristic can be exploited as liquid organic liquid fertilizer. Organic liquid fertilizer produced through biogas output has a really small macronutrient so that it is in demand to be increased. In this study, fermentation anaerobic is employed since it is more potential for waste processing of biogas output which has high organic substance. Liquid waste of digester biogas output is fermented for 10 days by adding activator for accelerating fermentation process and microorganism source as well as adding nutrient for influencing microorganism activity for increasing nutrients. The result showed that after being fermented anaerobically, content of nutrient in liquid organic fertilizer increased namely Nitrogen substance which was produced from 1,3598% to 2,5443%, P2O5 from 0,0489% to 0,07285%, and K2O from 0,8739% to 1,3636% for liquid fertilizer of digester sedimentation output. Liquid organic fertilizer of digester fermentation output, Nitrogen substance increased from 1,0724% to 2,1482%, P2O5 substance increased from 0,0412% to 0,0653%, and K2O substance increased from 0,8272% to 1,3169%.
