Abstract—This study aims to identify the performance of
biogas made by co-digesting dairy cattle feces and cattle rumen
waste. As we know, greenhouse gas emissions from the livestock
sector are one of the main factors causing global warming and
climate change. This sector accounts for about 14.5% of the total
greenhouse gas emissions in the world. One of the contributors
to emissions from this sector comes from cattle livestock. The
concept of renewable energy can be one of the solutions to
reduce the impact of greenhouse gas emissions from the
livestock sector. The study used four treatments with different
raw material mixtures for biogas. P0 consists of dairy cattle feces
only; P1 consists of 75:25 of dairy cattle feces to cattle rumen
waste; P2 consists of 50:50 of dairy cattle feces to cattle rumen
waste; and P3 consists of 25:75 of dairy cattle feces to cattle
rumen waste. Biogas is measured by CH4 production and flux
results. The results showed that the co-digestion of rumen waste
with dairy cattle feces increased CH4 production 2-3 times
higher than rumen waste only, and it depended on the ratio of
dairy cattle feces to rumen waste. We concluded that rumen
waste can be an alternative raw material for biogas production.
Optimal biogas production from rumen waste can be achieved
if rumen waste is digested together with dairy cow feces (codigestion)
with a composition of 25:75. Optimal conditions refer
to both results in CH4 yield and flux differing significantly from
the digestion of rumen waste alone.
