Pengaruh Penambahan Effective Microotganisms-4 Sebagai Biocatalyst Terhadap Peningkatan Konsentrasi Ammonium Sebagai Sumber Pupuk

Abstract

Organic waste processing in the form of vegetable residues can be processed anaerobically. To accelerate the rate of degradation of organic waste, Effective Microorganisms-4 can be added to the anaerobic process, which can produce high NH4 by-products. This study aimed to determine the effect of EM-4 on the production of NH4 in the anaerobic process of organic waste. The kinetic analysis of the organic waste degradation process was also investigated. The research methodology was carried out in a batch anaerobic reactor. The results showed that increasing EM4 concentration from 0 to 50 ml can increase the concentration of NH4 and be stable after the addition of more than 50 ml. The kinetic value (k) of the organic waste degradation was 0.0750 day-1 for no addition of EM-4 (0 ml), and the value of k increased after adding EM-4. The implication of this research is to provide a solution to reduce pollution of organic waste, and the resulting NH4 can be used as a source of plant fertilizer.
