The abundance of coconut water as a waste of household industry activities in Ponorogo can be obtained. There is still organic matter considered to become a liquid fertilizer where it can be expected to substitute for the use of inorganic fertilizers. The research aims to determine the potential of coconut water as a liquid organic fertilizer involving three types of microorganisms, such as Aspergillus niger, Pseudomonas putida and Effective Microorganisms (EM4). The experiment was conducted using a mixed bacth reactor with 4 L/ minute of aeration rate and initial microorganism`s number of approximately 107 cells/ mL for 10 days. The results suggest that the highest reduction of C-organic and the biggest enhancement of N, P, K can be achieved by a combination of A. niger and P. putida with 29 %; 100 %, 110 %, 552%, respectively.
