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
