Granular organic fertilizer is mostly/entirely made of organic materials through engineering
process that can be used to supply organic matter. Brem solid waste is material that can be used to make
granular organic fertilizer. Brem solid waste containing macro and micro nutrients  for plant growth. This
research aims to use brem solid waste as granular organic fertilizer. Examination of C/N ratio granular
organic fertilizer was 13.4, didn’t meet the quality standards of organic granular fertilizer which is 15-25.
The fertilizer water content was 7.81% which met the requirements of  7-15%. With C/N ratio of 13.4
fertilizers is accordance with the Minimum Technical Requirements of Organic Soil Fertilizer.The
conclusion shows that C/N ratio was 58.60. Compost C/N ratio was 13.6 that met compost quality
standard. Granular fertilizer C/N ratio was 13.4, didn’t meet granular fertilizer standard. The temperature
31-58°C, pH 6-7, 50-60% humidity. Initial weight was 39 kg, the moisture content was 17.05%. Weight
of compost was 7 kg. A ready granular fertilizer weigh is 7.2 kg, therefore the entire shrinkage weight
was 81.5%. Granular fertilizer contained 7.81% moisture content that met the standard. Brem waste
producers is suggested to manage their waste into economic value material (granular fertilizer).
