Upaya menurunkan gas CH4 dari industri peternakan menjadi solusi meminimalisir dampak global warming. Salah satunya yaitu dengan pemberian aditif pakan tinggi senyawa fenolik dan flavonoid. Penelitian ini dilakukan untuk menguji potensi aditif pakan ekstrak daun meniran (Phyllanthus niruri) terhadap produksi gas CH4, karakteristik fermentasi rumen, dan tingkat kecernaan nutrien pakan secara in vitro. Pada penelitian ini dilakukan empat perlakuan dengan empat replikasi terdiri dari kontrol 0?han kering (BK) (CTRL) dan tiga perlakuan suplementasi ekstrak dosis 0,5% BK (M1), 1,0% BK (M2), dan 1,5% BK (M3). Penelitian in vitro menggunakan cairan rumen sapi Bali (Bos sondaicus) dengan ransum basal rumput Pennisetum purpureum dan konsentrat (60:40). Analisis data dengan rancangan one-way ANOVA dilanjutkan uji lanjutan Duncan’s New Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa suplementasi ekstrak daun meniran menurunkan produksi gas CH4 berdasarkan jumlah BK, bahan kering tercerna (BKT), dan bahan organik tercerna (BOT) (P<0>0,05). Suplementasi ekstrak daun meniran tidak berpengaruh nyata terhadap nilai pH, kadar NH3, kadar protein mikroba, jumlah protozoa, dan kecernaan bahan organik (P>0,05), namun berpengaruh nyata terhadap peningkatan kecernaan bahan kering, total VFA, kadar propionat, dan kadar butirat (P<0>

Efforts to reduce CH4 gas production from the livestock industry are a challenge in minimizing the impact of global warming. One of the effort is the use of feed additives with high phenolic and flavonoid content. This research was conducted to explore the potential of meniran leaf extract (Phyllanthus niruri) as feed additive on CH4 gas production, rumen fermentation characteristics, and feed nutrient digestibility through in vitro approach. In this study, four treatments with four replicates were conducted, consisting control 0% DM (CTRL) and three treatments supplemented with extracts at doses of 0.5% DM (M1), 1.0% DM (M2), and 1.5% DM (M3). The in vitro study was conducted using rumen fluid from Bali cattle (Bos sondaicus) with a basal diet Pennisetum purpureum grass and concentrate (60:40). Data analysis was performed using one-way ANOVA and followed by Duncan's New Multiple Range Test (DMRT). The results showed that supplementation with meniran leaf extract reduced CH4 gas production based on dry matter, dry matter digested (DMD), and organic matter digested(OMD) (P<0>0,05). The supplementation had no significant effect on pH value, NH3 concentration, microbial protein concentration, protozoa cell count, and organic matter digestibility  (P>0,05), but had significant effect on increasing dry matter digestibility, total VFA, propionate concentration, butyrate concentration (P<0>
