and productivity degradation. Compost is one of the organic fertilizers produced fromÂ the biological decomposition process by a consortium of microorganisms, including
functional microorganisms. To make it easier for farmers and efficiency in the use ofÂ organic fertilizer, organic fertilizer will be further processed into granular form and is calledÂ Granules Organic Fertilizer (POG). In the manufacturing process, namely at the time ofÂ drying using a rotary dryer, was suspected of using high temperatures to kill microbesÂ (including functional microbial) that naturally exist in the organic compost fertilizer (POK),Â which is the raw material for POG. To increase the presence of functional microbialÂ populations, the POG which has produced before, then added with bio fertilizer that isÂ rich in microbial functional. This research was conducted to determine and evaluate theÂ total microbial population and functional microbial in pure POK, compared with the totalÂ microbial population and functional microbial in the POG are enriched with bio-fertilizer.Â The results showed: There is an indication to the higher number of total microbialÂ population in the POK, who showed by total fungi population, compared with the POG.Â The number of functional microbial population, as shown by bacterial phosphate solventÂ and non-symbiotic bacteria that are fastening N in POK, very high and already meetsÂ the criteria to be called as a biological fertilizer. The amount is not significantly differentÂ compared to the POG that is already enriched with bio fertilizer that is rich in microbialÂ functional. There is an indication of the influence of high heating using a rotary dryer,Â in the POG manufacturing process against the decreasing of the amount of microbial
population that are resulting in the POG, including functional microbial
