Properties of rabbit feces composting using indigenous Alcaligenes sp. LS2T and Arthrobacter sp. LM1KK

Abstract

This study aims to determine the effects of indigenous Alcaligenes sp. LS2T and Arthrobacter sp. LM1KK in the composting of rabbit feces. This study consists of 3 treatments (commercial starter as control, Alcaligenes sp. LS2T, and Arthrobacter sp. LM1KK) in triplicate replication. Starter growth profile, emitted ammonia concentration, physical qualities of compost, and the compost’s chemical quality were observed in this study. The data was analyzed using a randomized design (One-way ANOVA). Alcaligenes sp. LS2T has a significant ability to reduce ammonia emission compare to Arthrobacter sp. LM1KK and commercial starter. The best result of the chemical quality of compost was done by Arthrobacter sp. LM1KK with water content observed 28.78%, organic matter was 13.75%, 7.97% of C-organic, P total observed 1.38%, K determined 2.52%. Furthermore, the N value was 0.65%, and C/N Ratio observed 14.97%. As a conclusion, Alcaligenes sp. LS2T and Arthrobacter sp. LM1KK had the potency as same as with commercial starter for composting of rabbit feces. During the composting processes, the Alcaligenes sp. LS2T and Arthrobacter sp. LM1KK had a lower ammonia emission occurs compare to the commercial starter.
