Judul: The Behavior of Jonggol Sheep for 5 Hours After Long-Distance Transportation with Different Densities
Abstrak: Stres pada ternak akibat transportasi dapat dilihat dari perilaku ternak setelah proses transportasi. Penelitian ini bertujuan untuk mengevaluasi perbedaan tingkah laku domba Jonggol pada 5 jam pasca transportasi jarak jauh dengan kepadatan kendaraan yang berbeda. Lokasi penelitian ini berada di UP3J (Unit Pendidikan dan Penelitian Peternakan Jonggol) IPB dan Laboratorium Lapangan Ruminansia Kecil Blok B, Fakultas Peternakan IPB. Penelitian ini dilaksanakan selama 7 hari pada September 2022. Penelitian ini menggunakan 27 ekor domba Jonggol yang dibagi menjadi 3 perlakuan (P1: kepadatan 0,1 m2, P2: kepadatan 0,18 m2, P3: kepadatan 0,24 m2). Analisis data menggunakan metode statistik non parametrik Kruskal Wallis. Kepadatan saat transportasi menyebabkan perbedaan persentase tingkah laku berdiri dan lokomosi juga durasi lokomosi domba Jonggol pasca transportasi. Tingkah laku berdiri pada kepadatan 0,18 m2 lebih rendah dibanding lainnya, namun mempunyai tingkah laku lokomosi yang lebih tinggi dibanding lainnya. Hal tersebut menunjukkan terjadinya tingkah stres yang tinggi pada kepadatan 0,18 m2., Stress in livestock due to transportation can be seen from the behavior of livestock after the transportation process. This study aimed to evaluate the differences in behavior of Jonggol sheep in 5 hours after long-distance transportation with different vehicle densities. The location of this research is at UP3J (Unit Pendidikan dan Penelitian Peternakan Jonggol) IPB and Small Ruminant Field Laboratory Block B, Faculty of Animal Science IPB. This study was conducted for 7 days in September 2022. This study used 27 Jonggol sheep divided into 3 treatments (P1: density 0.1 m2, P2: density 0.18 m2, P3: density 0.24 m2). Data were analyzed by Kruskal Wallis' non-parametric method. Overcrowding during transportation causes differences in the percentage of standing behavior and locomotion as well as the duration of locomotion of Jonggol sheep after transportation. The standing behavior at a density of 0.18 m2 is lower than others, but has a higher locomotion behavior than others. This showed the occurrence of high stress behavior at a density of 0.18 m2.

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.
