Penelitian bertujuan untuk mengkaji pengaruh imbangan hijauan konsentrat dan lama ensilage yang berbeda terhadap kualitas fisik (warna, tekstur, keberadaan jamur) dan suhu silage complete feed. Materi yang digunakan dalam penelitian ini adalah limbah daun rami, rumput lapang, bungkil kelapa, onggok, molases, urea, garam dapur, dan mineral mix. Metode penelitian adalah eksperimental menggunakan Rancangan Acak Lengkap (RAL) pola faktorial, yaitu : Faktor 1 (I): Imbangan hijauan:konsentrat (I1) = 60:40; (I2) = 50:50; (I3) = 40:60 dan Faktor 2 (W): Lama ensilage (W0) = 0 minggu; (W1) = 1 minggu; (W2) = 2 minggu; (W3) = 3 minggu; (W4) = 4 minggu. Setiap susunan unit penelitian diulang sebanyak 3 kali, sehingga terdapat 45 susunan unit penelitian. Variabel yang diamati adalah karakteristik fisik (warna, tekstur dan keberadaan jamur) menggunakan metode Soekanto et. al. (1980) dan suhu. Data dianalisis menggunakan analisis variansi dan dilanjutkan dengan uji Beda Nyata Jujur (BNJ) dan uji Orthogonal Polynomial. Hasil penelitian menunjukkan bahwa tidak terdapat interaksi antara imbangan hijauan konsentrat dengan lama ensilage terhadap perubahan kualitas fisik dan suhu silage complete feed. Imbangan hijauan konsentrat yang berbeda berpengaruh nyata (P<0,05) terhadap kualitas fisik warna dan tekstur, namun tidak nyata terhadap keberadaan jamur dan suhu. Lama ensilage yang berbeda berpengaruh sangat nyata (P<0,01) terhadap peningkatan kualitas fisik warna dan penurunan suhu dan nyata (P<0,05) terhadap tekstur dan keberadaan jamur silage complete feed. Imbangan hijauan konsentrat 40:60 dan lama ensilage selama 3 minggu mampu mempertahankan kualitas fisik dan suhu silage complete feed paling baik.

The aim of this research was to study the effect of different forage-concentrate ratios and ensilage times on physical qualities (colour, texture, fungi) and temperature of complete feed silage. The materials of the research were ramie waste, field grass, cocoa meal, cassava cake, molasses, urea, salt and mineral mix. The research method was experimental using Completely Randomized Design (CRD), factorial pattern, i.e. :  1st factor (I): forages-consentrate ratios (I1) = 60:40; (I2) = 50:50; (I3) = 40:60 and 2nd factor (W): ensilage times (W0) = 0 week; (W1) = 1 week; (W2) = 2 week; (W3) = 3 week; (W4) = 4 week. Each research unit was repeated 3 times, so that it generated 45 research unit arrangements. The observed variables were physical characteristics (colour, texture and fungi) using Soekanto et. al. (1980) method and temperature. Data were analyzed using analysis of variance followed by honesty significance difference (HSD) and Orthogonal Polynomial Tests. The results of the research showed, interaction of forage-concentrated ratios with ensilage times didn’t affect complete feed silage’s physical characteristics and temperature. The use of different forage-concentrated ratios significantly (P<0.05) affected the improvement of physical qualities of colour and texture, however, it didn’t significantly affect the presence of the fungi and the temperature. Ensilage time showed highly significantly (P<0.01) affected to increase the qualities of colour and decreased temperature and significantly (P<0.05) increased the qualities of texture and fungi in complete feed silage. The best capable to maintain physical qualities of complete feed silage is 40:60 forage-consentrate ratio and 3-week ensilage.
