This research was conducted using In vitro technique for 48 hours of incubation time. The aim was to evaluate supplementation of Betel leaf meal to decrease methane production. Methane produced in the rumen was estimated by using data of volatile fatty acids (VFA) partial concentration, particularly three main acids, i.e. acetic acid, propionic acid and butyric acid. The experiment used block randomized design with three replicates and four treatments. The treatments were 0%, 1%, 2%, and 3% of betel leaf meal in feed. The results showed that suplementation of Betel leaf meal decreased methane and total gas production. Betel leaf meal also tended to decrease protozoa population (P<0.1), and increased propionic acid (C3) proportion and butiric acid (C4) proportion (P<0.05). The best dose of Betel leaf meal to reduce methane and to maintain optimum rumen condition was 2%.
