| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan mengkaji pengaruh interaksi rasio jerami padi amoniasi : konsentrat dengan taraf ekstrak etanol daun waru terhadap produk fermentasi rumen secara in vitro. Penelitian dilaksanakan secara eksperimental menggunakan Rancangan Acak Kelompok pola faktorial dua faktor. Faktor pertama yaitu rasio jerami padi amoniasi : konsentrat (R) (45:55, 55:45, dan 65:35) dan faktor kedua yaitu taraf suplementasi ekstrak etanol daun waru (0, 200 dan 400 ppm). Variabel yang diamati meliputi N-NH3, total VFA, asam asetat, asam propionat, asam butirat dan rasio Asetat/Propionat (A/P). Hasil penelitian menunjukkan bahwa tidak terdapat interaksi (P>0,05) antara rasio jerami padi amoniasi : konsentrat dan taraf ekstrak etanol daun waru terhadap N-NH3, total VFA, asam asetat, asam propionat, asam butirat dan rasio A/P. Rasio jerami padi amoniasi:konsentrat menunjukkan respon kuadratik terhadap asam asetat, total VFA dan rasio asetat/propionat. Suplementasi ekstrak etanol daun waru sampai 400 ppm menyebabkan penurunan N-NH3, asam asetat dan rasio A/P dan peningkatan asam propionat. Penurunan asam asetat, total VFA dan rasio A/P terbesar dicapai pada pemberian jerami padi amoniasi masing-masing sebesar 55,36%, 56,64% dan 53,75%. Berdasarkan hasil penelitian dapat disimpulkan bahwa rasio jerami padi amoniasi : konsentrat sebesar 53–55 : 45-47 merupakan rasio terbaik yang dapat menurunkan asam asetat dan rasio A/P. Suplementasi ekstrak etanol daun waru sampai 400 ppm berpengaruh linear negatif terhadap N-NH3, asam asetat dan rasio asetat/propionat serta berpengaruh linear positif terhadap asam propionat.

| Abtrak (Bhs. Inggris) | This experiment aimed to study the effect of the interaction rice straw amoniation : concentrate ratio with level of ethanolic extract of waru leaves on the rumen fermentation products in vitro. The experiment was conducted by experimental methode in randomized block design factorial with two factor. The first factor was the ratio of rice straw ammoniation and concentrate (R) (45:55, 55:45, and 65:35) and the second factor was the level etanolic extract of waru leaves (0, 200 and 400 ppm). The variables observed were N-NH3, total VFA, acetic acid, propionic acid, butyric acid and the ratio of Acetate/Propionate (A/P). The results showed that there were no interaction (P>0.05) between the ratio of rice straw amoniation : concentrate and level of ethanolic extract of waru leaves on the N-NH3, total VFA, acetic acid, propionic acid, butyric acid and Acetate/Propionate (A/P) ratio. Ratio of rice straw ammoniation : concentrate showed quadratic respond on acetic acid, total VFA and A/P ratio. Supplementation of ethanolic extract of waru leaves up to 400 ppm showed N-NH3, acetic acid and A/P ratio decrease and propionic acid increase. The highest decline of acetic acid, total VFA and A/P ratio achieved by rice straw ammoniation of 55,36%, 56,64% and 53,75% respectively. Based on the results of this study concluded that rice straw ammoniation : concentrate ratio 53-55 : 45-47 was best ratio can decrease acetic acid and Acetat/Propionate ratio. Supplementation of ethanolic extract of waru leaves up to 400 ppm showed negative linearly on N-NH3, acetic acid and Acetate/Propionate ratio and positive linearly on propionic acid. |
