BIOSOLID a solid waste originating from industrial waste water treatment and household waste in aerobic and anaerobic conditions. Biosolid this be the case for industries considering the amount of biosolid generated approximately large enough to reach 30-40 tonnes per day depending on the industry. Management conducted currently only used as embankment (land fills) and sent to Cilengsi to do further processing. This management requires substantial costs and no economic value on these biosolid. Based on literature review and laboratory analysis known biosolid contains various nutrient needed such plants: Nitrogen (N): 2-3%, Phosphorous (P2O5): 2-4%, Potassium (K2O): 0.5 to 1% and Sulfur (S): 0.2 to 0.4% and organic materials: 26-30%. In addition to containing nutrients, biosolid from industrial waste can contain pathogenic bacteria and heavy metals. Quality biosolid produced every type of industry vary depending on the type of industry and waste water treatment technology.
Biosolid treatment process intended to reduce the content of pathogenic bacteria and heavy metals contained in the biosolid and biosolid processing into carbon or biochar. The assessment in this study include: Identify the quantity and quality (physical, chemical and biological) of solid waste biosolid on various types of industries, processing: Extraction and Carbonization acid-base and the performance of biosolid and carbon (biochar) on agricultural land. After doing research, product standards obtained organic fertilizer (SNI), biosolid quality standards that can be applied to agricultural land.
Attention to the quality biosolid obtained can be used as fertilizer, growing media (carbon or biochar) that serves to improve the quality of agricultural land and land reclamation for agriculture, and avoiding environmental pollution (water, soil and air) and pollution on agricultural products .
