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 aim of this research was to study percentage carcass and commercial cut of broiler fed diet containing screened or unscreened palm kernel meal (PKM). Two hundred day old chicks (DOC) of broiler strain Hubbard were used and kept for 35 days. The diet treatments were R1 = diet containing unscreened PKM, R2 = diet containing screened PKM, R3 = diet containing screened PKM plus shell of PKM as grit, and R4 = diet containing screened plus commercial grit in completely randomized design with four treatments and four replications. Water and diet were given ad libitum. The results showed that there were significantly different (P<0.05) among treatments on the final body weight and carcass weight where broiler fed R1 and R4 were higher body weight and carcass weight than those broiler fed R2 and R3. Percentage carcass, commercial cut and abdominal fat were not significantly different all on all PKM diets. It was concluded that screening PKM did not affect percentage carcass and commercial cut of 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.
