ABSTRACT
Biochar Fertilizer is a fertilizer derived from biomass waste (corncob and rice husk) or livestock waste (chicken manure) which is solid and enriched with the addition of nitrogen elements that are useful to improve the physical, chemical and biological properties of the soil and enrich the nutrients in it. Another important role of biochar fertilizers is to fertilize crops, increase production yields and provide chlorophyll in plants. The purpose of this study was to add the nitrogen lost during the evaporation process in the pyrolysis reactor device. The pyrolysis process in this study used the selection of slow pyrolysis process with temperature of 5000C for 4 hours in the reactor. The missing nitrogen element needs to be added nitric acid to enrich the nitrogen element in biochar. Result of analysis from this research use Kjeldhal method. The Kjeldhal method is the method used to determine the nitrogen content in food or non-food. The best data in this research is found in chicken manure manure material with a concentration of 25% nitric acid for 3 days ie 3.62% N.
