Judul: Pengaruh Jenis Slat Kandang Panggung terhadap Cedera dan Performa Produksi Ayam Broiler
Abstrak: Cedera yang dapat ditimbulkan oleh lantai slat yang digunakan pada ayam broiler adalah Foot Pad Lession, Hock Burn, dan Breast Blister. Cedera yang terjadi pada ayam broiler akan berdampak pada penurunan produksi daging. Penelitian ini bertujuan mengevaluasi rataan cedera dan performa produksi ayam pedaging yang dipelihara di kandang panggung dengan jenis/bahan slat yang berbeda. Penelitian menggunakan ayam pedaging strain Jumbo 747 Hijau dari PT. Cibadak Indah Sari Farm. Variabel yang diukur adalah cedera dan performa produksi. Pengukuran dilakukan pada ayam berumur 35 hari. Data yang diperoleh dianalisis menggunakan uji T (Independent Samples T-test) untuk melihat pengaruh penggunaan slat konvensional dan slat plastik buatan pabrik terhadap performa produksi ayam broiler. Hasil penelitian menunjukkan penggunaan jenis slat yang berbeda hanya mempengaruhi persentase tingkat kejadian cedera Foot Pad Lesion (FPL) dan Hock Burn (HB), tetapi cedera tersebut tidak berpengaruh terhadap performa produksi (P>0,05). Konversi pakan yang lebih baik ditemukan pada slat konvensional dengan nilai sebesar 1,51. Mortalitas yang terjadi pada penelitian ini bukan disebabkan karena pengaruh jenis slat yang berbeda, melainkan faktor lain., Injuries that can be caused by slat floors used in broiler chickens are Foot Pad Lession, Hock Burn, and Breast Blister. Injuries that occur in broilers will have an impact on decreasing meat production. This study aims to evaluate the injury rate and production performance of broilers reared in stilt cages with different types/materials of slats. The study used the Jumbo 747 Hijau strain of broilers from PT. Cibadak Indah Sari Farm. The variables measured were injury and production performance. Measurements were made on 35 day old chickens. The data obtained were analyzed using the T test (Independent Samples T-test) to see the effect of using conventional slats and factory-made plastic slats on broiler production performance. The results showed that the use of different types of slats only affected the percentage of the incidence of Foot Pad Lesion (FPL) and Hock Burn (HB) injuries, but these injuries had no effect on production performance (P>0.05). Better feed conversion was found in conventional slats with a value of 1.51. The mortality that occurred in this study was not caused by the influence of different types of slat, but other factors.

Judul: Identification Injury of Rooster and Hen IPB-D1 Chickens in Maintenance of Free-range System
Abstrak: Chickens rearing in an intensive system with limited area causes chickens to be more easily stressed. Stressed can decreasing health of chickens and will have an impact on decreasing the quality and meat production that can be seen from the presence of injuries, such as foot pad dermatitis (FPD), hock burn (HB), and breast blister (BB). The aim of this study was to analyze and study the effect of the free-range system on injury in IPB-D1 chickens. This study used rooster and hen IPB-D1 chickens. This research is descriptive in nature by observing and assessing the soles of the feet, knees and breasts of the chickens. Injury assessment was carried out when the chicken were 8, 12, and 16 weeks old. The results showed that the incidence of foot pad dermatitis in rooster and hen chickens aged 12 weeks was 26.67% and 13.33%, respectively. Foot pad dermatitis injury increased to 40% in roosters and 33.33% in hens when the chickens were 16 weeks old. Breast blister injuries of 13.33% only occurred in roosters when they were 16 weeks old. Hock burn injuries did not occur in either roosters or hens., Pemeliharaan ayam dengan sistem intensif dengan penggunaan lahan yang terbatas menyebabkan ayam lebih rentan terkena cekaman stres. Adanya cekaman ini secara tidak langsung dapat menurunkan tingkat kesehatan ayam dan akan berdampak pada penurunan kualitas dan produksi daging. Penurunan kesehatan ayam dapat dilihat dari adanya cedera, seperti foot pad dermatitis (FPD), hock burn (HB), dan breast blister (BB). Penelitian bertujuan menganalisis dan mempelajari pengaruh sistem pemeliharaan free-range terhadap cedera pada ayam IPB-D1. Ayam yang digunakan dalam penelitian ini adalah ayam jantan dan betina IPB-D1. Penelitian ini bersifat deskriptif dengan cara mengamati dan menilai bagian telapak kaki, lutut, dan dada ayam. Penilaian cedera dilakukan saat ayam berumur 8, 12, dan 16 minggu. Hasil penelitian menunjukkan kejadian cedera foot pad dermatitis pada ayam jantan dan betina berumur 12 minggu berurutan sebanyak 26,67% dan 13,33%. Cedera foot pad dermatitis meningkat menjadi 40% pada ayam jantan dan 33,33% pada ayam betina saat ayam berumur 16 minggu. Cedera breast blister sebanyak 13,33% hanya terjadi pada ayam jantan saat berumur 16 minggu. Cedera hock burn tidak terjadi baik pada ayam jantan maupun ayam betina.

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.
