Judul: Pengaruh Pemberian Bio-ATP sebelum Transportasi Terhadap Respon Fisiologis, Susut Bobot dan Lama Rekondisi Domba Ekor Gemuk
Abstrak: Proses transportasi ternak dapat mengakibatkan ternak mengalami stres. Bio-Adenosine Triphosphate (Bio-ATP) diduga dapat digunakan dalam penanganan stres pada ternak. Penelitian ini dilakukan untuk mengevaluasi pengaruh pemberian Bio-ATP sebelum proses transportasi terhadap respon fisiologis, susut bobot dan lama rekondisi domba. Penelitian ini menggunakan 12 ekor domba ekor gemuk jantan umur ± 1 tahun dengan bobot badan rata-rata 21,92±3,40 kg. Perlakuan yang digunakan yaitu pemberian Bio-ATP sebanyak 2 mL dan tanpa pemberian Bio-ATP pada domba sebelum ditransportasikan. Peubah yang diukur yaitu respon fisiologis (frekuensi denyut jantung, laju respirasi, suhu rektal), susut bobot badan domba dan lama rekondisi domba. Data dianalisis menggunakan Uji T dengan enam kali ulangan untuk setiap perlakuan. Hasil respon fisiologis menunjukkan bahwa perlakuan pemberian Bio-ATP tidak berpengaruh nyata terhadap respon fisiologis domba (P>0,05). Pemberian Bio- ATP berpengaruh nyata terhadap persentase susut bobot badan (P<0,05). Lama rekondisi tidak berpengaruh nyata terhadap pemberian Bio-ATP sebelum transportasi (P>0,05). Kesimpulan dari penelitian ini adalah pemberian Bio-ATP sebelum proses transportasi dapat mengurangi stres dan memperkecil angka penyusutan bobot badan pada domba setelah proses transportasi.

Judul: Pengaruh Pemberian Minyak Kelapa dan Dextrose terhadap Respon Fisiologis dan Bobot Badan Domba Ekor Tipis Sebelum Transportasi
Abstrak: Transportasi ternak menyebabkan stres yang berakibat pada respon fisiologis dan penyusutan bobot badan ternak. Penelitian ini bertujuan menganalisis pemberian minyak kelapa dan dextrose pada domba ekor tipis sebelum transportasi. Penelitian ini menggunakan 9 ekor domba ekor tipis betina umur 8-12 bulan dengan rataan bobot badan 14,61±2,50 kg. Penelitian ini menggunakan Rancangan Acak Kelompok dengan 3 perlakuan yaitu kontrol, pemberian minyak kelapa sebanyak 4% dari bahan kering konsentrat yang diberikan, dan pemberian dextrose sebanyak 2,24 g kg-1 bobot badan dan dikelompokkan menjadi 3 berdasarkan bobot badan ringan, sedang, dan berat. Data dianalisis dengan Rancangan Acak Kelompok dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan bahwa pemberian minyak kelapa dan dextrose tidak berbeda nyata terhadap penyusutan bobot badan dan respon fisiologis, tetapi berbeda nyata terhadap lama rekondisi yaitu lama rekondisi perlakuan minyak kelapa lebih cepat dibandingkan perlakuan kontrol dan dextrose. Simpulan bahwa minyak kelapa yang diberikan pada domba ekor tipis dapat mempercepat masa rekondisi bobot badan domba., Livestock transportation causes stress which results in physiological responses and weight loss of livestock. This study aimed to analyze the administration of coconut oil and dextrose to thin-tailed sheep before transportation. This study used 9 female thin tailed sheep aged 8-12 months with an average body weight of 14,61±2,50 kg. This study used a Randomized Block Design with 3 treatments namely control, administration of coconut oil as much as 4% of the dry matter concentrate given, and administration of dextrose as much as 2,24 g kg-1 body weight and grouped into 3 based on body weight light, medium, and heavy. Data were analyzed by Randomized Block Design followed by Duncan's test. The results showed that the administration of coconut oil and dextrose was not significantly different to body weight loss and physiological response, but significantly different to the length of reconditioning, namely the length of reconditioning of coconut oil treatment was faster than the control and dextrose treatment. The conclusion is that coconut oil given to thin-tailed sheep can accelerate the reconditioning period of the sheep's body weight.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
