Abstrak: Metabolizable energy of ration containing Palm Kernel Cake (PKC) with and without screening were evaluated in broilers. 20 broilers (5 weeks of age) were assigned randomly to 4 treatments and 4 replications. The treatments were P1= Diet containing 7.5% PKC without screening, P2= Diet containing 7.5% PKC with screening of PKC, P3= Diet containing 7.5% PKC screening+shell of PKC, P4= Diet containing 7.5% PKC screening+commercial grit. Parameters measured were energy retention, nitrogen retention and metabolizable energy (Apparent Metabolizable Energy, True Metabolizable Energy). The result showed that metabolizable energy of ration containing PKC with and without screening were not significant and were lower compared with metabolizable energy of commercial diet. It is concluded that screening of PKC using 0.589 mm mash was not effective to improve metabolizable energy of ration containing 7.5% PKC in broiler.

Judul: Performa Ayam Broiler yang Diberi Pakan Mengandung Bungkil Inti Sawit dengan atau tanpa Penyaringan
Abstrak: Palm kernel meal (PKM) is a by-product of oil extractions of palm kernel. The use of PKM in the ration of monogastric animals is limited as a result of high fibre. The main objective of this study was to evaluated the performance of broiler fed diet containing PKM with or without screening. Two hundreds DOC were divided into 20 groups and assigned to one of four diet treatment i.e : P1 = treatment diet + 7.5% PKM without screening and adding grit; P2 = treatment diet + 7.5% screened PKM without adding grit; P3 = treatment diet + 7.5% screened PKM + 2% shell of PKM; P4 = treatment diet + 7.5% screened PKM + 2% commercial grit. Data from completely randomized design were analyzed variance (ANOVA). Feed and water were given ad libitum. The result showed that screened palm kernel meal decreased crude fibre (from 33.13% to 30.58%). However, screened PKM did not affect feed intake, body weight gain, and feed conversion. It is concluded that PKM with ot without screening did not affect broiler performance.

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.
