Lemongrass is the raw material for lemongrass oil production. Indonesia one of ten largest producing countries in world. industry will be generated large amount waste. The aim this study was to determine effect elephant grass (Pennisetum purpureum) substitution with waste on high forage feed vitro rumen fermentation. This arranged randomized block design 5 treatments (100R: 0% waste, 75R: 25% 50R: 50% 25R: 75% and 0R: 100% waste) 4 different collecting time as block. results showed that did not give a significant difference dry matter content, but it could reduce protein content increase crude fiber fat significantly (P <0.05). analysis affect pH, gas production rate, butyric acid, valeric iso-butyric iso-valeric acid both terms quantity proportion. used by (75R) affected organic matter, potential methane (24 hours) decreased increased lag (p concentration partial VFA profile decreasing acetic acid. A A/P ratio occurred 100%. substituted up high-forage without production, digestibility, total VFA.
