<![CDATA[ABSTRAK. Penelitian bertujuan untuk mengevaluasi performan dan produksi karkas itik lokal yang diberi ransum mengandung limbah ikan leubim (Canthidermis maculata). Materi penelitian yang digunakan adalah 100 ekor itik lokal jantan umur 1 hari yang dipelihara hingga umur 16 minggu. Metode penelitian dilakukan secara eksperimental menggunakan Rancangan Acak Lengkap (RAL) yang terdiri 5 perlakuan ransum dan 4 ulangan. Perlakuan ransum yang digunakan adalah : R0 (ransum kontrol /tanpa limbah ikan leubim), R1 (ransum mengandung 10% tepung kulit ikan leubim), R2 (ransum mengandung 10% tepung kepala ikan leubim), R3 (ransum mengandung 10% tepung tulang ikan leubim), dan R4 (ransum mengandung 10% kombinasi limbah ikan leubim/tepung kulit, kepala dan tulang). Variabel yang diamati yaitu: konsumsi ransum, bobot badan akhir, konversi ransum, mortalitas, bobot karkas dan persentase karkas. Data yang diperoleh dianalisis dengan Analysis of Variance (ANOVA) dan dilanjutkan dengan uji jarak berganda Duncan. Hasil penelitian menunjukkan bahwa pemberian ransum yang mengandung tepung limbah ikan leubim sebanyak 10% dalam formulasi ransum memberi pengaruh yang signifikan (p0,05) terhadap konsumsi ransum, bobot badan akhir, nilai konversi ransum, bobot karkas dan persentase karkas itik lokal jantan umur 16 minggu, namun tidak berpengaruh nyata terhadap mortalitas. Kesimpulan penelitian adalah penggunaan kombinasi limbah ikan leubim (tepung kulit, kepala dan tulang) sebanyak 10% dalam formulasi ransum dapat meningkatkan bobot badan akhir, bobot karkas dan persentase karkas, serta dapat menurunkan konversi ransum itik lokal jantan umur 16 minggu.(Performance and carcass production of local ducks by ration containing of leubiem fish waste (Canthidermis maculata))ABSTRACT. The purpose of this study was to determine the effect of the use of leubim fish (Canthidermis maculata) waste in ration formulations on the performance and carcass production of local ducks. The research material used was 100 male local ducks 1-16 weeks old. The research method was conducted experimentally using a Completely Randomized Design (CRD) consisting of 5 treatments and 4 replications. The treatment ration used was as follows: R0 (control ration/without leubim fish waste), R1 (ration containing 10% leubim fish skin), R2 (ration containing 10% leubim fish head), R3 (ration containing 10% leubim fish bone), and R4 (ration contains 10% combination of leubim fish waste/skin, head, and bones). The observed variables were: feed consumption, final body weight, feed conversion, mortality, carcass weight, and carcass percentage. Data were analyzed with Analysis of Variance (ANOVA). The results showed that the use of leubim fish waste in ration 10% had a significant effect (p0.05) on ration consumption, final body weight, conversion ratio, carcass weight, and carcass percentage of male local ducks, but did not significantly affect mortality. The study concluded that the use of 10% leubim fish waste combination in ration formulation could increase the final body weight, carcass weight, carcass percentage and decrease feed conversion of the male local ducks age 16 weeks.]]>
