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: Effect of Density on Physiological Responses and  Performance of Local Sheep on Long Distance Transport
Abstrak: Pengangkutan domba menjadi faktor yang tidak dapat dihindari dalam rantai pasok dan kepadatan menjadi salah satu penyebab stres selama transportasi. Penelitian bertujuan menganalisis pengaruh tingkat kepadatan selama transportasi terhadap respon fisiologis, penyusutan bobot badan, dan durasi rekondisi domba lokal, serta analisis biayanya. Penelitian menggunakan 10 ekor domba lokal betina dewasa. Penelitian dilakukan dengan mengangkut domba dengan kepadatan 0,18 m2 ekor-1 dan 0,24 m2 ekor-1 dengan transportasi jarak jauh berdurasi 11 jam 30 menit. Variabel yang diamati meliputi respon fisiologis (suhu rektal, denyut jantung, dan laju respirasi), susut bobot, durasi rekondisi, dan analisis biaya. Data dianalisis menggunakan Uji T berpasangan untuk menilai kondisi domba sebelum dan setelah perlakuan dan Uji T tidak berpasangan untuk membandingkan rataan kedua kepadatan. Domba mengalami stres akibat transportasi ditandai dengan perubahan yang signifikan pada respon fisiologis dan susut bobotnya. Tingkat kepadatan tidak mempengaruhi perubahan suhu rektal, denyut jantung, laju respirasi, susut bobot, dan durasi rekondisi domba lokal. Domba yang diangkut menggunakan tingkat kepadatan 0,18 m2 ekor-1 lebih efisien secara ekonomi karena penggunaan biaya yang lebih rendah., Sheep transportation is an unavoidable factor in the supply chain and density is one of the stressors during transportation. The aim of this study was to analyse the effect of density level during transportation on physiological responses, body weight loss, recovery of local sheep, and cost analys. The study used 10 female and mature local sheep. The study was conducted by transporting sheep with densities of 0,18 m2 head-1 and 0,24 m2 head-1 with long journey transport of 11 hours 30 minutes duration. The observed variables included physiological responses (rectal temperature, heart rate, and respiratory rate), weight loss, recovery, and cost analys. The data were analyzed using the paired T test to analyse sheep condition before and after the treatment and 2 sample T test to compare of both densities. Sheep experienced stress due to transportation characterized by significant changes in physiological responses and body weight lost. Density level didn’t affect changes in rectal temperature, heart rate, and respiratory rate, weight loss, and recovery duration of local sheep. Sheep that transported by density level 0,18 m2 head-1 economically are more efficient with lower cost.

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.
