Abstract
The residue must be processed to dispose or utilize the residue of the installation processing unit safely. To ensure no environmental contamination occurs, the residual/sludge must be in stable condition. The measurement of the respirometry index values, both static (SRI) and dynamic (DRI), could be used to measure the stability. The stability indicators of respirometry measure the oxygen needed to break down biodegradable organic matters. The purpose of this study is to identify the characteristics and analyze the stability of sludge/digested samples from several places based on water content approach, volatile solids, C/N ratio, SRI, and DRI values. The objective is to develop recommendations for continued processing of unstable sludge/mud/digestat. Further processing uses composting of Takakura baskets for 14 days with coconut shell bulking agents.
