Judul: Internal Organs Profile of IPB-D1 Chickens Fed Diet Containing Jack Bean Meal (Canavalia ensiformis L.) and Lactic Acid Bacteria in Drinking Water
Abstrak: Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian tepung koro pedang (Canavalia ensiformis L.) dalam ransum dan bakteri asam laktat dalam air minum terhadap profil organ dalam ayam IPB-D1. Penelitian ini menggunakan rancangan acak lengkap faktorial (2x2). Faktor (1) tepung koro pedang (0%, 20% dalam ransum) dan (2) bakteri asam laktat (0, 107 CFU/ml). Peubah yang diamati adalah jantung, hati, ginjal, timus, bursa Fabricius, limpa, pankreas, empedu, proventrikulus, gizzard, duodenum, jejunum, ileum, sekum dan kolon. Tepung koro pedang nyata (p, This experiment was aimed to evaluation effect of providing jack bean meal (Canavalia ensiformis L.) in diet and lactic acid bacteria in drinking water on the internal organs profile of IPB-D1 chickens. This study used a factorial completely randomized design (2x2). Factors (1) jack bean meal (0%, 20% in diet) and (2) lactic acid bacteria (0, 107 CFU/ml). The variables observed were heart, liver, kidneys, thymus, bursa of Fabricius, spleen, pancreas, gallbladder, proventriculus, gizzard, duodenum, jejunum, ileum, cecum and colon. Jack bean meal significantly (p

Judul: The Effect of Vitamin E and Selenium Supplementation towards the Internal Organ Characteristics of IPB-D2 Chickens during Developer-Layer Period
Abstrak: Penelitian ini bertujuan mengevaluasi pengaruh suplementasi vitamin E dan mineral Se dengan komposisi kebutuhan nutrien yang berbeda terhadap kualitas organ dalam Ayam IPB-D2. Rancangan percobaan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) Faktorial 2 x 2 (faktor A untuk jenis rasum dan faktor B untuk suplementasi vitamin E sebanyak 100 ppm dan jumLah mineral Se 1 ppm, masing-masing perlakuan diulang sebanyak lima kali. Peubah yang diamati yaitu bobot potong unggas, bobot dan persentase organ dalam ayam IPB-D2 (hati, jantung, empedu, limfa, ginjal, rampela, thimus, bursa, pankreas, dan proventikulus). Data diolah menggunakan uji ANOVA. Hasil penelitian menunjukkan tidak terdapat interaksi antara pemberian jenis ransum berbeda dan suplementasi vitamin E dan mineral Se terhadap persentase bobot organ dalam. Jenis ransum berpengaruh sangat nyata pada kenaikan persentase bobot empedu (P<0,01), namun pemberian suplementasi vitamin E dan Se tidak berpengaruh nyata pada kenaikan bobot organ tersebut. Sedangkan jenis ransum serta suplementasi vitamin E dan Se berpengaruh nyata pada persentase bobot proventikulus (P<0,05)., This study aimed to evaluate the effect of vitamin E and mineral Se supplementation with different compositions of nutrient requirements on the internal organ quality of IPB - D2 Chickens. The experimental design used in this study was a 2 x 2 factorial completely randomized design (CRD) (factor A for the type of ransum and factor B for vitamin E supplementation of 100 ppm and the amount of mineral Se 1 ppm. Each treatment was repeated as much as five times. The variables observed were slaughter weight of poultry, weight and percentage of internal organs of IPB-D2 chickens (liver, heart, bile, spleen, kidney, rampella, thymus, bursa, pancreas, and proventiculus). The data is processed using the ANOVA test. The results showed there was no interaction between giving different types of rations and vitamin E and mineral Se supplementation on the percentage of internal organ weights. Type of rations had a very significant effect on increasing bile weight (P<0.01), but vitamin E and Se supplementation did not significantly affect the increase in the percentage weight of the organ. While the type of ration and vitamin E and Se supplementation are significantly affected proventiculus percentage weight (P<0.05).

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.
