Abstract

Nowadays, organic fertilizer is more interesting than anorganic fertilizer, because it doesn’t cause soil degradation and the crops are healthier to be consumed. Manure is the most familiar as an organic fertilizer. This study dealt with producing of liquid organic fertilizer from cow manure in fixed bed column reactor. The reactor operated at 30 oC, 40 cmHg and 19.2 mL/s of solvent flowrate. The aim of this study was to find correlation between bed height of manure in column, particle size of manure, concentration of fertilizer and volumetric mass transfer coefficient (kca). The highest of kca value was obtained at 25 cm of bed height, it was 0.0014 s-1. The result shows that bed height of manure is linier to kca. On the other hand, particle size of manure doesn’t give much influence of kca.
