Judul: Morphometric Index of Garut Sheep and Crossing Results
Abstrak: Indeks morfometrik merupakan salah satu alternatif untuk menilai jenis dan fungsi ternak. Penelitian ini bertujuan untuk memperoleh nilai morfometrik domba garut dan hasil persilangannya. Penelitian ini mengukur morfometrik 46 ekor domba garut dan hasil persilangannya. Peubah yang diukur adalah panjang badan, tinggi badan, tinggi pinggul, lingkar dada, dalam dada, lebar dada, lebar pinggul, panjang pinggul, dan bobot badan. Data yang diperoleh dianalisis secara deskriptif dengan menghitung rata-rata dan simpangan baku. Selanjutnya dihitung indeks morfometri dan diuji apakah terdapat perbedaan nyata antar morfometrik masingmasing persilangan dengan menggunakan uji t independen. Hasil penelitian ini menunjukkan tinggi badan dan tinggi pinggul domba pejantan garut lebih besar dibandingkan domba dorper dan batur. Ukuran tubuh anakan lepas sapih jantan dan betina tidak berbeda antara domba garut dan hasil persilangannya. Domba pejantan garut memiliki nilai height slope index dan foreleg length indeks lebih besar dibandingkan domba dorper dan batur. Ukuran indeks morfometrik domba anakan lepas sapih jantan garut lebih besar dibandingkan dengan hasil persilangannya terkait index weight, height slope indeks, dan foreleg length index., Morphometric index is one of the alternatives to assess the type and function of livestock. This study aims to obtain morphometric values of garut sheep and their crosses. This study measured the morphometrics of 46 garut sheep and their crosses. The measured variables were body length, body height, hip height, chest circumference, chest depth, chest width, hip width, hip length, and body weight. The data obtained were analyzed descriptively by calculating the mean and standard deviation. Furthermore, the morphometric index was calculated and tested whether there were significant differences between the morphometrics of each cross using the Independent T test. The results of this study showed that the body height and hip height of garut rams were greater than dorper and batur sheep. The body size of male and female weanlings did not differ between garut sheep and their crosses. garut rams have greater height slope index and foreleg length index values than dorper and batur sheep. The morphometric index size of garut male weaned lambs is greater than the results of their crosses related to index weight, height slope index, and foreleg length index.

Judul: Evaluasi Morfologi dan Sistem Indeks Serta Respon Fisiologis Domba Ekor Tipis dan Domba Garut pada Umur dan Ransum yang Berbeda
Abstrak: This paper is concerned of body measurements associated with production characteristics also as indicators of type of sheep. The experiment was conducted at university area on morphology and physiologycal respone (pulse rate, respiration rate, and rectal temperature) in intensive system. Live weight and eight body measurements were taken on 32 local sheep consisted of 16 garut sheep (8 fat lamb and 8 yearling) and 16 javanese thin-tailed sheep sheep (8 fat lamb and 8 yearling). They were divided into two groups and given Indigofera sp. and mung bean waste. The data were recorded every 30 days. The body measurements used were live weight, shoulder width, foreleg length, body length, rump height, rump width, rump length and heart girth. The indices used were weight, height slope, length index, width slope, depth index, foreleg length, balance and cumulative index. The data were analyzed by factorial 2x2 (body measurements) and 2x2x3 (physiologycal respone) with Statistix 8.0. The measured parts were highly correlated. Tested indices showed that both sheep are typical of meat animals. This was shown by the cumulative index, length and balance indices which were 1,66; 0,91; and 0,75 for both breeds. The respective coefficient of variation between breeds indicates the opportunity for improving the breeds through selection. The index results of index system showed that in both sheep had height slope/cumulative index, height slope index/length index and weight index were significantly (P<0.01) correlated. Rectal temperature in the morning was higher than at noon and afternoon. The physiological result showed that there were significant differences (P<0,01) on respiration by time, also rectal temperature and pulse rate by time and breed.

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.
