Abstract
Organic waste is produced from various daily activities and, if not properly treated, can have a negative impact on human health and the environment. Anaerobic digestion is a promising method for converting organic waste into methane gas, a renewable energy source. However, conventional anaerobic processes often fail to optimise methane production. This study aims to increase methane gas production by adding cow rumen substrate and using a multi-stage biodigester in the anaerobic process. The study was conducted over 35 days under anaerobic conditions, with cow rumen substrate added to single-stage and two-stage biodigesters. The resulting methane gas was then compared with that produced by biodigesters without the addition of cow rumen substrate. Methane production from both types of biodigesters was also compared to determine which produced better results. The results showed that the two-stage biodigester with rumen addition produced the highest methane concentration, namely 0.0392%. The effect of cow rumen content substrate made methane gas production faster than without the addition. The best composition in this study was in the biodigester with the addition of 1 kilogram of rumen content substrate with a carbon value of 52.61 and a nitrogen value of 2.478. The C/N ratio value was 21.23. However, the pH condition in all biodigesters was too acidic, resulting in less than optimal results. These findings indicate that the addition of cow rumen inoculum can increase anaerobic activity and methane production, so the combination of cow rumen inoculum with a multistage biodigester has the potential to be a breakthrough for sustainable biogas production and is worthy of further research.
