PENGARUH SUBSTITUSI DEDAK PADI DENGAN BONGGOL PISANG FERMENTASI DAN BUNGKIL KEDELAI DENGAN INDIGOFERA FERMENTASI TERHADAP PERFORMA BROILER (The Effect of Substitution of Rice Bran with Banana Hump and Soybean Meal with Indigofera zollingeriana Fermented to Broiler Performances)

Abstrak Tujuan penelitian yaitu untuk mengetahui pengaruh substitusi dedak padi dengan bonggol pisang fermentasi dan bungkil kedelai dengan Indigofera zollingeriana fermentasi terhadap performa broiler. Penelitian dilaksanakan di kandang percobaan Kampung Babakan Jambe, Desa Pasawahan, Kecamatan Tarogong Kaler, Kabupaten Garut mulai bulan Agustus sampai September 2018. Penelitian menggunakan 200 ekor ayam broiler strain Cobb dari PT. KMS tanpa dilakukan pemisahan antara jantan dan betina. Metode penelitian adalah metode eksperimental dengan menggunakan Rancangan Acak Lengkap (RAL) pola faktorial dengan perlakuan pertama yaitu tingkat substitusi dedak padi dengan bonggol pisang fermentasi (B) terdiri dari 5 taraf perlakuan, yaitu : b0 = 0%, b1 = 1,25%, b2 = 2,50%, b3 = 3,75% dan b4 = 5,00%, sedangkan perlakuan kedua yaitu tingkat substitusi bungkil kedelai dengan Indigofera zollingeriana fermentasi (I) terdiri dari 5 taraf perlakuan, yaitu : i0 = 0%, i1 = 6,50%, i2 = 13,00%, i3 = 19,50% dan i4 = 26%, sehingga terdapat 25 kombinasi perlakuan dengan masing-masing 2 ulangan. Hasil penelitian menunjukkan bahwa subsitusi dedak padi dengan bonggol pisang dan bungkil kedelai dengan Indigofera zollingeriana fermentasi tidak berpengaruh terhadap konsumsi ransum, secara mandiri masing-masing berpengaruh terhadap pertambahan berat badan, dan terjadi interaksi antara substitusi bonggol pisang dan Indigofera zollingeriana fermentasi terhadap konversi ransum. Subsitusi dedak padi dengan bonggol pisang fermentasi 5% dan bungkil kedelai dengan Indigofera zollingeriana fermentasi 13% menghasilkan performa optimal pada ayam broiler.

Abstract The purpose of this research is to know about the substitution effect of rice bran with banana hump fermented and soybean meal with Indigofera zollingeriana fermented to feed consumption, daily gain and feed conversion.. The research was conducted at Babakan Jambe, Pasawahan Village, Tarogong Kaler Sub District, Garut Regency and carried out from August until September 2018. This Research used 200 broilers with Cobb strain from PT. KMS with straight run method. The research used experimental method with design used was a Completely Randomized Design (CRD) factorial pattern with the first treatment, namely substitution of rice bran with banana hump fermented (B) consisting of 5 levels, namely : b0 = 0%, b1 = 1,25%, b2 = 2,50%, b3 = 3,75% and b4 = 5,00%, and the second treatment is the level substitution of soybean meal with Indigofera zollingeriana fermented (I) consisting 5 levels of treatment, namely: i0 = 0%, i1 = 6.50%, i2 = 13.00%, i3 = 19.50% and i4 = 26%, so the number of treatment combinations is 25 which is twice repeated. The results showed that there was not significat effect between the level substitution of banana hump and Indigofera zollingeriana fermented on the feed consumtion, there was independent effect on daily gain and there was interaction to feed conversion. Substitution rice bran with banana hump fermented until 5% and soybean meal with Indigofera zollingeriana fermented until 13% show optimal performance of broiler.
