Abstract

At present, some sesame dehulling businesses cannot handle overloaded liquid waste and choose to dispose sesame dehulling liquid waste directly into sewers or rivers. The organic matter in sesame dehulling wastewater disposed directly into the environment causes many environmental problems. One alternative for handling liquid waste with organic content is to use it as biogas through an anaerobic process. In this study, data collection was carried out through direct experiments with laboratory-scale reactors. The experimental design used consisted of four combinations of wastewater treatment from sesame dehulling and cow dung starter (1:0; 9:1; 7:3; 1:1) with a total volume of 3 L and two types of digesters (focusing on gas production and focus on the substrate) with two repetitions for a total of 16 trials. The study was conducted for 40 days. The factors that were observed and tested were the ratio of carbon/nitrogen, the value of Chemical Oxygen Demand and pH every 10 days, the temperature of the substrate every day, the amount of biogas produced every day, the total biogas produced, and the content of the biogas produced. The data obtained were then analyzed using descriptive statistical analysis. The results showed that for 40 days retention time, the higher the content of cow dung starter, the higher the volume of biogas and methane content produced. Experiments with a 1:1 substrate produced a maximum biogas of 498 mL per day, a total biogas of 8.461 mL, and a methane content of 49.61%. Meanwhile, the highest decrease in Chemical Oxygen Demand for 40 days occurred at 1:0 substrate, which was 13.342,20 mg/L. The decrease occurred from the original 16,.711,20 mg/L to 3.369,0 mg/L. 40 days is not enough to lower the COD to environment safe limit.
