Abstrak: The objective of current study was to investigate the effect of feeding diet containing sieved or unsieved palm kernel meal on the development of the digestive organs in 35-day old broilers. Two hundreds day old chicken strain Hubbard were allocated to four dietary treatments i.e : P1 = treatment diet containing unsieved palm kernel meal; P2 = treatment diet containing sieved palm kernel meal; P3 = treatment diet containing sieved palm kernel meal plus shell of Palm Kernel Meal (PKM) as grit; P4 = treatment diet containing sieved palm kernel meal plus commercial grit in completely randomized design. Feed and water were given ad libitum. Variables measured were weight percentage of proventriculus, gizzard, small intestine, caeca, colon, relative length of small intestine, colon and caeca. The result showed that weight percentage of proventriculus, gizzard, small intestine, and colon were not affected by the treatments. Relative length of jejunum, colon, and caeca were also not affected by the treatments. It is concluded that sieving palm kernel meal did not affect weight percentage and relative length of digestive organs of broiler chicken.

Abstrak: The use of palm kernel in the diet should be limited, because it contains high crude fiber and crude fat and low protein. The objective of this study was to determine the effect of feeding diets containing palm kernel powder added pollard or rice bran on percentage of internal organs in broiler chickens. The treatments were as follow : P1: control, P2: feed A (feed containing palm kernel powder added pollard ), P3: feed B (feed containing palm kernel powder added rice bran). The results showed that percentage of weight of the liver and bile were not significantly affected by the treatment. However the treatments significantly (P<0.01) affected the percentage of weights and relative lengths digestive organs where the percentage of weights were higher, and relative lengths were longer for treatments compared with that of control, while P2 and P3 results are comparable, except pancreas and colon. It is concluded that feeding diets containing palm kernel powder added pollard or rice bran produces a comparable percentage of internal organs in broiler chicken, but not to the pancreas and colon where feed containing palm kernel powder added pollard higher than feed containing palm kernel powder added rice bran.

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.
