Judul: Kadar Serum Darah Ayam  Petelur yang Diberi Air Rebusan Daun Sirih
Abstrak: This study was conducted to determine the effect of utilization Piper betle Linn leaves boiled water addition on lipid metabolism in serum of laying hen. The research used thirty laying hens (19 weeks of age). Completely randomized design used in this experiment with 5 treatments and 3 replications, each replication consist of 2 animals. The treatments : P1 (basal diet), P1 + 5 ml Piper betle Linn. leaves boiled water, P1 + 7.5 ml Piper betle Linn. leaves boiled water, P1 + 10 ml Piper betle Linn. leaves boiled water and P1 + 12.5 ml Piper betle Linn. leaves boiled water. The diet contain 17% crude protein and 2915 kcal/kg metabolizable energy. The variables observed were triglyceride, cholesterol, HDL and LDL serum of laying hen. The data obtained were analyzed with analysis of variance (ANOVA). The result showed that the treatment diets had significant effects on cholesterol, triglycerides and HDL of blood serum but not significant on LDL and total cholesterol concentrations of yolk.

Judul: The Performance and Blood Lipid Profile of Laying Hens Fed with Feed Containing meals of Temu Ireng (Curcuma aeruginosa) and Eggshell
Abstrak: Temu ireng sebagai antioksidan alami dan kerabang telur sumber kalsium dapat ditambahkan dalam ransum ayam petelur. Tujuan penelitian ini mengkaji pengaruh penambahan tepung temu ireng dan kerabang telur terhadap performa ayam petelur serta kadar lipid darah ayam petelur. Penelitian ini menggunakan rancangan acak lengkap (RAL) 3 perlakuan dan 4 ulangan, tiap ulangan terdiri dari 6 ekor ayam, sehingga total sebanyak 72 ekor ayam petelur strain Lohmann brown umur 45 minggu. Perlakuan terdiri dari P0 (pakan kontrol), P1 (P0+0,15% temu ireng dan kerabang telur), dan P2 (P0+0,3% temu ireng dan kerabang telur). Peubah yang diamati meliputi performa produksi ayam petelur (konsumsi ransum, produksi telur, FCR dan egg mass), kalsium darah dan profil lipid darah (trigliserida, kolesterol, HDL dan LDL). Data dianalisis dengan annova dan uji lanjut Duncan. Hasil yang diperoleh adalah penambahan tepung temu ireng dan kerabang telur nyata (P<0.05) meningkatkan performa produksi, namun tidak nyata berpengaruh (P>0.05) terhadap profil lipid darah ayam petelur. Simpulan penelitian yaitu penambahan P2 dengan dosis 0,3% tepung temu ireng dan kerabang telur dalam ransum menurunkan konsumsi, memperbaiki FCR dan meningkatkan produksi telur, egg mass, IOFC serta kalsium darah. Penambahan tepung temu ireng dan kerabang telur ini tidak memengaruhi profil lipid darah. Kata Kunci: ayam petelur, kerabang telur, lipid darah, performa, temu ireng

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.
