Judul: Gambaran Darah Merah Ayam Petelur pada Awal Masa Produksi yang Dicekok dengan Ekstrak Etanol Daun Kemangi
Abstrak: Laying hens are responsive to stress which can cause a decrease in physiological status and production. Empirically, ethanol extract of kemangi leaves can cure various diseases in humans. Uses of ethanol extract of kemangi leaves in animals have not been widely applied. This research was conducted to observe the physiological status of laying hens fed ethanol extract of kemangi leaves. Red blood profile variables observed were red blood cells, hematocrit (PCV), and hemoglobin. Twelve laying hens were divided into 4 groups and each treatment group consisted of 3 chickens as replication. The first treatment group was not given ethanol extract of kemangi leaves as a control(C), the second treatment group was given orally ethanol extract of kemangi leaves with the dose of 1 mg/kg bw(P1), the third treatment group was given orally ethanol extract of kemangi leaves with the dose of 2 mg/kg bw(P2), and the fourth treatment group was given orally ethanol extract of kemangi leaves with the dose of 3 mg/kg bw(P3). The results showed that administration of ethanol extract of kemangi leaves with the dose of 1 mg/kg body weight could improve the physiological status of laying hens during the first week of treatment. Flavonoids, saponins, and tannins contained in ethanol extract of kemangi leaves are possible to improve the physiological condition of laying hens. Meanwhile, ethanol extract of kemangi leaves a dose of 2 mg/kg body weight and 3 mg/kg body weight can decrease red blood parameters in chiken

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: 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.
