Judul: The Effect of Feed Withdrawal Time Lengths  Pre Transportation towards Glucose Levels in Blood, Life Weight, and Carcass of  Broiler Chicken
Abstrak: Ayam broiler harus dipuasakan sebelum diangkut. Pemuasaan pakan diperlukan untuk mengosongkan sistem pencernaan pada karkas sebelum disembelih. Penelitian dilakukan untuk menganalisis penyusutan bobot badan ayam broiler dari pengaruh perbedaan lama pemuasaan sebelum transportasi. Penelitian ini menggunakan 126 ekor ayam broiler dengan bobot rata-rata 1,4 kg pada umur 28 hari. Penelitian menggunakan Rancangan Acak Lengkap yang terdiri dari tiga perlakuan dan tiga ulangan. Parameter yang diukur yaitu penyusutan bobot badan, kadar glukosa darah, dan persentase karkas. Penelitian ini menggunakan analisis deskriptif. Hasil penelitian menunjukkan bahwa pemuasaan memiliki pengaruh terhadap penyusutan bobot badan, kadar glukosa darah, dan persentase karkas. Disimpulkan bahwa pemuasaan selama empat jam memiliki pengaruh yang baik daripada tanpa pemuasaan dan pemuasaan selama delapan jam., Broiler Chickens have to fasten from the feed before transportation. Feed withdrawal is needed to empty the digestive system to avoid carcass contamination during slaughtering. This study analyzes the weight loss, blood glucose, and carcass percentage of broiler chickens as the results of different fasting times before transportation. The study used 126 broiler chickens with an average weight of 1,4 kg at 28 days of age. A Completely Randomized Design is applied. The experimental design consists of three treatments consist of no fasting (P1), four hours fasting (P2), and eight hours fasting (P3) with three repetitions. One repetition consists of 14 broilers. The parameter observed was the weight loss, glucose levels in the blood, and carcass percentage. Data are analyzed descriptively. Results showed that fasting time affected body weight loss, blood glucose levels, and carcass percentage. Four hours fasting time before transportation showed better results than no fasting time and eight hours fasting time.

Judul: Penyusutan dan Mortalitas Ayam Broiler pada Jarak Tempuh yang Berbeda Selama Pengangkutan
Abstrak: Transportation aspects of broiler chickens to slaughterhouse are concerned to reduce bodyweight and to increase number of mortality. The experiment was conducted to study the bodyweight loss and mortality of broiler chickens caused by transportation with different travelling distances. Chickens were transported to slaughterhouse at age of 40 days with average bodyweight at 1.5 kg and delivered from 3 different farms location in Bogor (50 km), Lebak (83 km), and Pandeglang (153 km), and observation was 3 times replicated. The percentage of bodyweight loss during travelling from Bogor, Lebak, and Pandeglang was 3.33 ± 0.06%, 3.73 ± 0.76%, and 4.50 ± 1.13%, respectively. The percentage of mortality during travelling from Bogor was 0.26 ± 0.17%, Lebak 0.74 ± 0.56%, and Pandeglang 0.46 ± 0.35%. There is a linear correlation between the percentage of bodyweight loss and the travelling distances of transported broiler chickens. but there is no correlation between mortality and the travelling distances. The highest percentage of mortality were from Lebak (83 km), Pandeglang (153 km), and Bogor (50 km), respectively.

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.
