Judul: Effect of transportation on performance  and blood profile of thin tailed sheep
Abstrak: Livestock transportation that does not consider the animal welfare can affect the physiological condition of livestock which causes stress so that it affects the blood profile and weight loss. This study aimed to analyze effect of transportation on performance and blood profile of thin-tailed sheep which were transported for 8 hours. This study used 8 local rams with body weight of 18-23 kg which was devided into 2 treatments namely control = no transportation and, P1 = with transportation. The variables were physiological response, weight loss and blood profile. The data obtained were analyzed using Independent samples T test. The results of the study were that P1 have a significant effect on weight loss, blood haematology and neutrophil of sheep, but not significantly different on rectal temperature, heart rate, respiration rate, lymphocyte, N/L Ratio eosinophils, and monocytes. The transportation process for 8 hours caused an increase of body weight loss and differences in blood hematology and leukocyte differentials, namely the levels of neutrophils which indicated that the sheep were under stress during transportation., Transportasi yang tidak memperhatikan kesejahteraan hewan dapat mempengaruhi kondisi fisiologis ternak yang menyebabkan stres sehingga mempengaruhi profil darah dan penyusutan bobot badan. Penelitian ini bertujuan untuk menganalisis pengaruh transportasi terhadap performa dan profil darah domba ekor tipis yang ditransportasikan selama 8 jam. Penelitian ini menggunakan 8 ekor domba lokal jantan dengan bobot badan 18-23 kg yang dibagi menjadi 2 perlakuan yaitu kontrol, dan P1 = domba ditransportasikan selama 8 jam dengan peubah yaitu respon fisiologis, penyusutan bobot badan dan profil darah. Data yang diperoleh dianalisis menggunakan Uji T Tidak Berpasangan. Hasil penelitian berpengaruh nyata terhadap penyusutan pada bobot badan, hematologi darah dan netrofil domba, tetapi tidak berbeda nyata terhadap respon fisiologis, limfosit, rasio N/L, eosinofil dan monosit. Proses transporasi selama 8 jam dapat menyebabkan peningkatan pada penyusutan bobot badan dan perbedaan pada gambaran hematologi darah dan diferensial leukosit yang mengindikasikan domba mengalami stres selama transportasi.

Judul: Physiological Response and Weight Loss of Local Sheep in Long Distance Transportation with Different Densities
Abstrak: Transportasi menjadi salah satu faktor krusial dalam pengiriman ternak, dimana perbedaan kepadatan kandang pada saat pengangkutan dapat membuat ternak mengalami stres dan menurunkan bobot badannya. Penelitian ini bertujuan untuk menganalisis pengaruh perbedaan kepadatan pada moda transportasi terhadap penyusutan bobot badan dan respon fisiologis domba lokal. Materi penelitian berupa 10 ekor domba lokal betina berumur I4 dengan bobot badan berkisar kg. Perlakuan yang digunakan yaitu kepadatan 0,1 m2/ekor dan 0,18 m2/ekor selama transportasi jarak jauh dengan masing-masing 5 ekor domba. Peubah yang diamati ialah penyusutan bobot badan, respon fisiologis sebelum dan sesudah traansportasi hingga rekondisi bobot badan. Data dianalisis dengan uji-T berpasangan dan tidak berpasangan untuk membandingkan penyusutan bobot badan dan respon fisiologis pada kepadatan yang berbeda. Domba yang ditransportasikan dengan kepadatan 0,1 m2/ekor dan 0,18 m2/ekor selama 11–30 jam mengalami penyusutan bobot badan 0,37 dan 0,13. Hasil penelitian berpengaruh nyata terhadap susut bobot badan dan respon fisiologis, tetapi tidak berbeda nyata terhadap waktu rekondisi Transportasi menyebabkan cekaman stres dengan meningkatnya respon fisiologis. Kepadatan yang berbeda tidak mempengaruhi perbedaan susut bobot, lama rekondisi, dan respon fisiologis domba yang ditransportasikan. Kepadatan 0,1 m2 dapat mengurangi biaya produksi per ekor dengan jumlah domba yang dapat diangkut menjadi lebih banyak, sehingga biaya per ekor yang dikeluarkan menjadi lebih rendah., Transportation is one of the crucial factors in livestock delivery, where differences in the density of cages during transport can stress cattle and reduce their weight. This study aims to analyze the effect of density differences in the mode of transportation on body weight loss and the physiological response of local sheep. The research material consisted of 10 female local sheep aged I4 with body weights ranging from 21,19 ± 2,64 kg. The treatments used were densities of 0,1 m2/head and 0,18 m2/head during long-distance transportation with 5 sheep each. The variables observed were body weight loss, physiological responses before and after transportation, and body weight reconditioning. Data were analyzed by paired and unpaired t-tests to compare body weight loss and physiological responses at different densities. The sheep that were transported with a density of 0,1 m2/head and 0,18 m2/head for 11–30 hours experienced a decrease in body weight of 1,40 ± 0,37 and 1,26 ± 0,13. The results of the study had a significant effect on body weight loss and physiological response, but did not significantly differ on reconditioning time. Transportation causes stress by increasing physiological responses. The different densities did not affect differences in weight loss, reconditioning time, or the physiological response of the sheep being transported. A density of 0.1 m2 can reduce production costs per head by allowing more sheep to be transported, resulting in lower costs per head.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
