“Substitusi Bungkil Kedelai dengan Konsentrat Protein Bungkil Biji Jarak Fermentasi dalam Pakan terhadap Bobot Gizzard dan Usus Ayam Pedaging” telah dilaksanakan di Green House, Fakultas Peternakan, Universitas Jenderal Soedirman, pada tanggal 18 Oktober 2017 sampai dengan tanggal 18 Desember 2017. Tujuan penelitian ini adalah mengetahui pengaruh penggantian bungkil kedelai dengan konsentrat protein bungkil biji jarak fermentasi dalam pakan terhadap bobot gizzard dan usus ayam pedaging dan mengkaji level terbaik ditinjau dari bobot gizzard dan usus ayam pedaging. Materi yang digunakan adalah DOC ayam pedaging sebanyak 60 ekor. Penelitian dilakukan dengan menggunakan metode eksperimen dan menggunakan Rancangan Acak Lengkap (RAL). Perlakuan yang diuji adalah penggantian bungkil kedelai dengan konsentrat protein bungkil biji jarak fermentasi terdiri atas R0 (tanpa konsentrat protein bungkil biji jarak fermentasi), R1 (konsentrat protein bungkil biji jarak fermentasi 6%), R2 (konsentrat protein bungkil biji jarak fermentasi 12%), R3 (konsentrat protein bungkil biji jarak fermentasi 18%). Peubah yang dicatat dan diamati adalah bobot gizzard dan usus ayam. Rataan bobot gizzard  hasil penelitian R0, R1, R2, R3, berturut-turut adalah 15.7 g; 16.1 g; 14.7 g; dan 10.3 g. Rataan  bobot usus hasil penelitian R0, R1, R2, R3, berturut-turut adalah 25.7 g; 24.7 g; 22.6 g; dan 18.5 g. Hasil analisis variansi menunjukkan bahwa penggantian bungkil kedelai dengan bungkil biji jarak fermentasi dalam pakan berpengaruh nyata (P<0.05) terhadap bobot gizzard dan usus ayam. Kesimpulan dari penelitian ini adalah konsentrat protein bungkil biji jarak fermentasi dapat menggantikan bungkil kedelai sebanyak 4.63% apabila ditinjau dari bobot gizzard dan sebanyak 0.0000735% apabila ditinjau dari bobot usus.

“The Substitution of Soy Bean Meal by Fermented Protein Concentrate of Jatropha Seeds Cake in the Broiler Chicken Feed on the Gizzard and Intestine Weights of Broiler Chicken” was done in the Green House, Animal Science Faculty, Jenderal Soedirman University, from October, 18th, 2017 until December 18th 2017. The purposes of this research were to study the effect of soy bean meal substitution by concentrate protein of jatropha seed cake in the broiler chicken feed on the gizzard and intestine weights of broiler chicken and to study the best level of concentrate protein of jatropha seed cake that can substitute soy bean meal in the feed. The materials that were used in this research were 60 heads broiler chicken DOCs. This research used experiment methods and the design of this research used was Completely Randomized Design. The treatments of this research were the substitution of soy bean meal with fermented concentrate protein of jatropha seed cake, consisted of R0 (without fermented concentrate protein jatropha of seed cake), R1 (substituted by 6% of fermented concentrate protein of jatropha seed cake), R2 (substituted by 12% of fermented concentrate protein of jatropha seed cake), and R3 (substituted by 18% of fermented concentrate protein of jatropha seed cake). Data variables that measured were gizzard weight and intestine weight of broiler chicken. The means of gizzard weights of R0, R1, R2, R3 were 15.7 g; 16.1 g; 14.7 g; and 10.3 g. The means of intestine weight 25.7 g; 24.7 g; 22.6 g; and 18.5 g. The results showed that the treatments affected (P<0.05) the gizzard and intestine weights. The conclusion of this research, is that the fermented jatropha seed cake can replace the soy bean meal in feed until 4.63% based on the gizzard weight of broiler chicken and only 0.000735% based on the intestine weight of broiler chicken.
