Judul: Effect of Niacinamide Supplementation on Hematology Profile and Feed Consumption of Madura Cattle
Abstrak: Transportasi merupakan salah satu tahapan penting dalam bisnis peternakan. Penelitian ini bertujuan untuk menguji dampak suplementasi niacinamide terhadap konsumsi pakan, hematologi, dan glukosa darah pada fase pemulihan sapi Madura pasca transportasi jarak jauh selama 18 jam. Penelitian ini menggunakan 14 ekor sapi Madura pejantan dengan bobot badan (224,64±13,1 kg), yang dibagi menjadi dua kelompok perlakuan dengan masing-masing 7 ulangan (n=7). Perlakuan terdiri dari P0 = kontrol, dan P1 = niacinamide 1000 mg ekor-1 hari-1. Sapi diobservasi selama 28 hari pasca-transportasi. Parameter yang diukur, yaitu konsumsi pakan, profil hematologi darah, dan kadar glukosa darah. Data dianalisis menggunakan repeated measures analysis of variance (ANOVA) dan analisis t-test. Hasil penelitian menunjukkan bahwa suplementasi niacinamide sebesar 1000 mg ekor-1 hari-1 pada sapi Madura menurunkan monosit pada minggu pertama, dan memperbaiki hematokrit pada minggu kedua. Konsumsi BK, glukosa darah, dan profil hematologi darah pasca-transportasi kecuali jumlah limfosit dan basofil mengalami perbaikan selama masa pemeliharaan. Disimpulkan bahwa suplementasi 1000 mg ekor-1 hari-1 niacinamide berpengaruh terhadap profil darah, namun, tidak terhadap konsumsi sapi Madura pasca transportasi., The objective of this study was to investigate the effects of niacinamide on the recovery rate of Madura beef cattle after long distance transportation. Fourteen Madura bulls (BW 224.64 ± 13.1 kg) were equally divided into two treatments, i.e., control and niacinamide supplementation. The cattle were transported on the same truck for 18 hours and were observed for 28 days after transportation. After transportation, cattle were fed either control or 1000 mg head-1 day-1 niacinamide supplemented diet. The parameters observed were feed intake, blood glucose level, and hematology profile. Repeated measures ANOVA and t-test was used to analyze the data. Niacinamide supplementation of 1000 mg head-1day -1 did not affect feed intake, hematology profile, and blood glucose level except PCV and monocyte count. Time affects feed intake, blood glucose, and hematology profile except for lymphocytes and basophyle count. In conclusion, 1000 mg head-1 day-1 niacinamide supplementation affects blood profile but not feed intake.

Judul: Pengaruh Pemberian Vitamin C terhadap Respon Fisiologis dan Profil Metabolit Darah Sapi Saat Transportasi Jarak Jauh
Abstrak: Penelitian ini bertujuan menguraikan pengaruh pemberian vitamin C pada transportasi untuk mengurangi pengaruh stres perjalanan pada sapi. Penelitian ini menggunakan 10 ekor sapi PO yang ditransportasikan dari Kabupaten Kebumen menuju Bogor dengan jarak 416 km. Data fisiologi yang meliputi suhu rektal, respirasi, denyut jantung, data penurunan bobot badan dan data metabolit darah dianalisis dengan uji t. Data suhu permukaan tubuh dan suhu rektal dianalisis dengan korelasi pearson. Suhu, kelembaban makro serta data THI dianalisis secara deskriptif. Dosis pemberian vitamin C sebesar 1500 mg/ekor dengan bobot rata-rata 234,70±6,82 kg. Hasil penelitian menunjukan pemberian vitamin C berpengaruh nyata mengurangi penurunan bobot badan, mempertahankan respirasi, dan denyut jantung (P<0,05) namun tidak berpengaruh nyata terhadap suhu rektal, kadar glukosa dan kreatinin darah (P>0,05). Dapat disimpulkan bahwa pada penelitian ini pemberian vitamin C memberikan pengaruh positif dalam menurunkan stres akibat transportasi sehingga berdampak pada stabilnya respon fisiologis dan mengurangi penurunan bobot badan sebesar 9,65±3,00% lebih rendah dari perlakuan kontrol sebesar 19,88±4,94%. Pemberian vitamin belum dapat menurunkan kadar glukosa dan kreatinin darah setelah pengangkutan kembali ke normal., This research was conducted to find out how the effect of vitamin C on transportation to reduce the effects of stress transportation in cattle. Ten cattles were used which were transported from Kebumen Regency to Bogor with a distance of 416 km. Physiology data which include rectal temperature, respiration, heart rate body, weight loss and blood metabolite data including blood glucose and creatinine were analyzed using t-test. Data body surface temperature and rectal temperature were analyzed by Pearson correlation, temperature and macro humidity and THI data were analyzed descriptively. The dose of vitamin C is 1500 mg for each cattle with average body wight around 234,70±6,82 kg. The results showed that giving vitamin C can reduce stress which causes weight loss, had a significant effect on respiration and heart rate (P <0,05) and had no significant effect on rectal temperature, blood glucose and creatinine levels (P> 0,05). It can be concluded that in this study the of giving vitamin C had a positive effect in reducing stress due to transportation this condition would reduce body weight loss by 9.65±3 % lower than control treatment of 19.88±4.49 %. However, giving vitamin C has not been able to change blood glucose and creatinine levels after transportation to the ideal value.

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.
