Judul: Pengaruh pemberian ekstrak daun beluntas (Pluchea indica Less.) pada air minum terhadap performan ayam broiler pada kepadatan kandang yang tinggi
Abstrak: Broiler has very fast growth and efficient in utilizing the diet.-However broiler is easy to get stress, including heat stress. Adding sintetic antistress into drinking water is common practice by farmer, but results in higher cost production and residue accumulation in meat broiler. To overcome this problem, this esperiment extract of beluntas leaf was used into drinking water to study its effect on the performance of broilers and its effort on cholesterol. Two hundreds and sixteen Day Old Chick (DOC) were used in this experiment The animals were devided into 24 groups. each consisted of 9 broilers and were kept in animal house with litter system.

Judul: Evaluasi penambahan tepung daun beluntas (Pluchea indica L.) dalam ransum terhadap tampilan produksi ayam broiler pada kepadatan kandang yang tinggi
Abstrak: This research was conducted to study the effcct of beluntas leaf powder usage in the diet on performances (feed consumption. body weight gain, :eed conversion, water consumption) and cholesterol of the broilers. The research used 162 DOC (day old chicken) strain CP 707. The treatment diets were : R1 (commercial feed without beluntas leaf powder or vitastress). R2 (RI + virastress), R3 (commercial feed + 2% beluntas leaf powder). R4 (commercial feed + 4% beluntas leaf powder),'RS (commercial feed + 6% beluntas leaf powder) and R6 (commercial feed + 8% beluntas leaf powder). The data were analyzed using Analyses of Variance and any significant different were further tested usins Least Significant Difference. The results showed that the treatment diets significantly increased (P<0.01) final body weigh1 and body weight gain and significantly increased (PcO.05) feed consumption and water consumption . However, the treatment diet significantly decreased (P<0.01) feed covenion. Usage of 2?'o beluntas leaf powder gave the best performances i.e., 1,152 g/bird (final body weigh), 1,114g/bird (body weigh gain). 1,69 1 ghird (feed consumption), 1.44 (feed conversion) and A.617mlhird (water consumption). Usage of beluntas leaf powder decreased the cholesterol content of broiler's meat.

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.
