Sludge Biogas liquid waste oil palm is an output product of anaerobic fermentation that can be utilized as organic fertilizer and biological fertilizer. The results of chemical properties analysis showed that there are macro and micro nutrients needed plant N total 346.32 mg/l, P total 79.96 mg/L, available P 125.06 mg/l, K 0.9%, Ca 0.02%, Mg 0.03%, Na 2364.33 mg/L and Cu 0.44 mg/L. Analysis of biological properties can be explained that the biogas sludge contains functional microbes i.e. nitrogen and phosphate solvent bacteria and has a population of 480 x 104 CFU/ML and 42 x 104. Nitrogen and bacterial phosphate solvent bacteria can be utilized as biological fertilizer, which helps to availability of nitrogen and phosphate nutrients in the soil.
