Abstract
Composting is an aerobic microbiological method that is persuaded by microorganisms such as bacteria and fungi. Microorganisms perform degradation by the use of water and oxygen and result in the production of compost, carbon dioxide, heat, and water. It enriches the soil and reduces the need for chemical fertilizers by recycling various organic material and nutrients to the soil. The maturation phase is responsible for determining the final quality of the mature compost. To order to identify the optimal composting decomposition conditions, this study is designed to optimize the parameters for isolated bacteria from the maturation stage of the compost. An important similarity of the isolated bacteria from the maturation stage of composting process was also observed between temperature, pH, OD and EC. It was observed that optimizing the parameters of the compost promotes the rate of decomposition, product stability, and humification process. In this phase, therefore, further research is required to improve the aerobic composting process and reduce the composting time.
