Judul: Performa ayam broiler dengan pakan silase ransum komersil
Abstrak: Penelitian ini bertujuan untuk mengetahui efektifitas dan taraf penggunaan silase ransum terhadap performa ayam broiler. Ternak yang digunakan, DOC (Day Old Chick) sebanyak 120 ekor yang dipelihara selama 5 minggu. Penelitian ini dilaksanakan dari bulan September sampai Oktober 2005. Ransum penelitian mengandung protein kasar sebesar 23,21% dan kandungan gross energy sebesar 4.284 kkal/kg. Perlakuan dalam penelitian ini adalah ransum komersil sebagai kontrol (R0), ransum campuran dengan rasio 50% ransum komersil: 50% ransum komersil yang dibuat silase (R1), ransum komersil yang dibuat silase (100% silase) (R2). Ransum dan air minum diberikan ad libitum. Rancangan percobaan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap dengan 3 perlakuan dan 5 ulangan. Setiap ulangan terdiri dari 8 ekor ayam. Data yang diperoleh dianalisis dengan ANOVA (Analysis of Variance), dan jika berbeda nyata dilanjutkan dengan uji kontras orthogonal. Peubah yang diamati meliputi konsumsi ransum, pertambahan bobot badan, bobot badan akhir, konversi ransum dan mortalitas. Hasil penelitian menunjukkan bahwa pemberian silase ransum sangat nyata (P<0,01) mempengaruhi konsumsi ransum. Rataan konsumsi ransum selama perlakuan adalah 1.897 sampai 2.168 g/ekor, Konsumsi perlakuan R1 sangat nyata (P<0,01) lebih tinggi dibandingkan dengan kontrol dan konsumsi perlakuan R2 sangat nyata (P<0,01) lebih rendah daripada kontrol, tetapi perlakuan tidak nyata mempengaruhi pertambahan bobot badan dan bobot badan akhir. Perlakuan R2 mempunyai nilai konversi ransum yang tidak nyata dibandingkan kontrol, tetapi perlakuan R1 mempunyai nilai konversi ransum yang sangat nyata (P<0,01) lebih tinggi dibandingkan dengan kontrol. Mortalitas selama penelitian sebanyak 1 ekor. Hasil penelitian menunjukkan bahwa pemberian silase ransum tidak berpengaruh negatif terhadap performa ayam broiler.

Abstrak: The experiment was conducted to evaluate the effect of silage of commercial diet on feed consumption, feed conversion, body weight gain and frnal body weight of broiler. The experiment was conducted in Completely Randomized Design using 120 day old chicks (DOC) Cobb 500 strain. The animals were divided into 15 group and assigned randomly to one of three dietary treatments, namely: RO (commercial diet as control), R1 (50% silage of commercial diet + 500/0 control ration) and R2 (1W/o silage of commercial diet). The results showed that dietary treabnents significantly (PQ),Ol) influenced feed consumption and feed conversion, but the treatments did not significantly influence body weight gain and final body weight Feed consumption and feed conversion of broiler fed 50% silage was significantly higher compared with that of control. Feed consumption of broiler fed 1 W? silage was significantly lower compared with that of control, but the diet compared with control produced similar feed conversion. It was concluded that silage could be used up to 108% for broiler ration without negative effect on broiler's performance. Keywords : silage commercial diet, performance, broiler

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
