Judul: Physiological Response and Performance of Landrace Pigs at Different Transportation Duration
Abstrak: Transportasi ternak adalah proses memindahkan ternak dari suatu tempat ke tempat yang lain dengan tujuan distribusi. Transportasi ternak berdampak langsung terhadap ternak, diantaranya ternak mengalami cekaman suhu lingkungan, perubahan fisiologis dan penyusutan bobot badan. Tujuan penelitian ini adalah menganalisis respon fisiologis dan performa ternak babi Landrace pada durasi pengangkutan yang berbeda. Data dianalisis menggunakan RAL (Rancangan Acak Lengkap) dengan tiga perlakuan durasi berbeda yaitu P1= 1 jam, P2= 2 jam dan P3= 3 jam dengan peubah yang diukur adalah denyut nadi, laju pernafasan, suhu rektal dan bobot badan. Data bobot badan dianalisis menggunakan sidik ragam, sementara data mikroklimatik dan rekondisi respon fisiologis dianalisis deskriptif. Hasil penelitian menunjukkan bahwa respon fisiologis dan performa babi Landrace setelah loading dan sebelum unloading menunjukkan hasil yang berbeda pada setiap perlakuan. Rekondisi babi Landrace tidak menurun secara signifikan dalam satu jam. Pengangkutan ternak babi dapat dilakukan dengan durasi optimal 2 jam., Livestock transportation is the process of moving livestock from one place to another with the purpose of distribution. Livestock transportation has a direct impact on livestock themselves, including livestock experiencing stress due to environmental temperature, changes in physiological responses and reduction in body weight. The study aimed to analyze the physiological response and performance of landrace pigs at different transportation durations. Data were analyzed using RAL (Completely Randomized Design) with three different time treatments, namely P1=1 hour, P2=2 hours and P3=3 hours on heart rate, respiratory rate, rectal temperature and body weight. Descriptive analysis is used for microclimatic data and physiological response reconditioning. The results showed that the pulse rate and body weight of landrace pigs after loading and before unloading showed different results between treatments. The results of landrace pig reconditioning data concluded that it did not decrease significantly within one hour. Transporting pigs can be carried out with an optimal duration of 2 hours.

Judul: The Sheep’s Physiological Response and Performance are Transported at Different Density After Long Distance Land Transmission
Abstrak: Pengangkutan domba merupakan kegiatan yang dapat menimbulkan stress pada domba yang ditunjukkan dengan penurunan bobot badan dan peningkatan respon fisiologisnya. Penelitian ini bertujuan untuk mengidentifikasi pengaruh kepadatan yang berbeda pada saat transportasi terhadap performa, respon fisiologis, lama waktu rekondisi serta analisis biaya. Penelitian ini menggunakan 10 domba betina dewasa dengan bobot 20,48±3,04kg dan diangkut dengan kepadatan 0,1 m2 ekor-1 dan 0,24 m2 ekor-1 selama 11 jam 30 menit. Variabel yang diamati meliputi susut bobot, respon fisiologis(suhu rektal, denyut jantung, dan laju respirasi), durasi waktu rekondisi serta analisis biayanya. Data dianalisis menggunakan Uji T tidak berpasangan untuk membandingkan rataan kedua kepadatan dan Uji T berpasangan untuk menilai kondisi domba sebelum dan setelah transportasi. Domba mengalami stress akibat perjalanan, hal ini ditandai dengan perubahan yang signifikan pada bobot badan dan respon fisiologisnya, namun kepadatan yang berbeda tidak berpengaruh nyata pada perubahan respon fisiologis dan waktu rekondisi domba. Domba yang diangkut dengan kepadatan 0,1 m2 ekor-1 lebih efisien secara ekonomi karena penggunaan biaya yang lebih rendah., Sheep transportation is an activity that may cause stress to the sheep, indicated by weight loss and changes in physiological response. The aim of this study was to investigate the effect of density level during transportation on performance, physiological response, recovery time, and cost analysis. This study used 10 female mature sheep with body weight 20,48±3,04kg and transporting with densities of 0,1 m2 head-1 and 0,24 m2 head-1 with long time transport journey 11 hour and 30 minutes duration. The observed variables include weight loss, physiological response(rectal temperature, heart rate, and respiratory rate), recovery time, and cost analys. Data were analysed using 2 sample T-test to compare of both density and using the paired T-test to analysed sheep condition before and after transportation. The sheep experienced stress due to transportation characterized by significant changes in weight loss and physiological response, but different of density level do not significantly affect changes in physicological response and recovery time. Sheep transported with density 0,1 m2 head-1 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.
