One of the factors that influence biogas production is the C/N ratio of the substrates. In this study the bagasse as a carbon-rich substrate (C/N=58) is combined with nitrogen-rich substrate namely is water hyacinth (C/N=19) so that the C/N ratio is in the range of 20-30. The research was carried out by preparing a filtered substrate with a 200 mesh sieve. Microbes needed to decompose the substrate are cow rumen, activated sludge from rotten bagasse and rotten water hyacinth. At the stationary phase, the ratio F/M of 0.5 and C/N ratio of 20, 25, 30, the each of biogas yield produced (liter/kg COD removed) are 381, 351 and 339.
