| Abstrak (Bhs. Indonesia) | Penelitian bertujuan untuk mengkaji level penambahan cairan rumen terbaik dalam meningkatkan produksi biogas dan mempersingkat waktu inkubasi dari pembentukan biogas skala laboratorium. Penelitian menggunakan percobaan eksperimental skala laboratorium. Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 6 blok. Materi percobaan yang digunakan feses sapi perah yang diencerkan menggunakan air dengan perbandingan 1:1,26. Perlakuan yang diujicobakan adalah R0 (tanpa penambahan cairan rumen), R1 (R0 + cairan rumen 10%), R2 (R0 + cairan rumen 15%) dan R3 (R0 + cairan rumen 20%). Data yang diperoleh dianalisis menggunakan analisis variansi (ANAVA). Jika perlakuan berpengaruh nyata, dilanjutkan dengan uji orthogonal polynomial.Hasil penelitian menunjukkan bahwa penambahan cairan rumen berpengaruh nyata terhadap produksi biogas dan waktu inkubasi (P<0,05). Rataan R0, R1, R2 dan R3 masing-masing 20,67 ml, 27,50 ml, 28,33ml, dan 26,83ml, sedangkan rataan waktu inkubasi, R0, R1, R2, dan R3 masing-masing membutuhkan waktu 6,5 hari, 3,7 hari, 4,8 hari dan 4,5 hari. Kesimpulan dari penelitian ini bahwa penambahan cairan rumen 10% (R1) menghasilkan waktu inkubasi tersingkat (3,7 hari) dan produksi gas yang cukup tinggi (12,26 ml). |

| Abtrak (Bhs. Inggris) | The aim of this research were to analize the best level of rumen liquor addition to increase the amount of biogas and reduce the incubation time of biogas production on laboratory scale. This research used the experimental methode with 4 treatments and 6 blocks. The design of this research was Randomized Complete Block Design. The materials of this experiment was dairy cattle feces which was diluted by water with 1:1.26 ratio. The tested treatments were R0 (without rumen liquor addition), R1 (R0 + rumen liquor 10% ), R2 (R0 + rumen liquor 15%), R3 (R0 + rumen liquor 20%). Data were obtained and analyzed using analysis of variance (ANAVA). If the results showed significant effect, the data analysis will be continued using orthogonal polynomial test.The results of research showed that the rumen liquor addition significantly affected the amount of biogas and incubation time (P<0.05). The averages of gas production of R0, R1, R2 and R3 were 20.67ml, 27.50ml, 28.33ml, and 26.83ml, whereas the averages of incubation time of R0, R1, R2 and R3 were 6.5 days, 3.7 days, 4.8 days, and 4.5 days respectively. The conclusion of this research is the 10% addition (R1) of rumen liquor gives the shortest time of incubation (3.7 days) and moderate of gas production (12.26 ml). |
