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: Profil Fenotipik Domba Garut dan Hasil Persilangannya
Abstrak: Penelitian ini bertujuan mengidentifikasi profil fenotipik sifat kualitatif hasil persilangan antara induk betina domba Garut dengan pejantan dari rumpun berbeda. Sampel domba yang digunakan dalam penelitian ini berjumlah 166 ekor dari rumpun domba berbeda. Penelitian dilakukan dengan mengamati sifat kualitatif domba yang terdiri dari; warna bulu, pola bulu, bentuk dan warna tanduk, bentuk telinga, bentuk ekor dan profil muka domba. Metode yang digunakan dalam penelitian ini adalah observasi langsung di lapangan yang dilanjutkan dengan analisis deskriptif dan perhitungan frekuensi relatif. Hasil penelitian menunjukkan warna bulu putih-hitam memperoleh nilai persentase tertinggi pada pejantan Garut (50%), pejantan Doper (100%), induk betina Garut (60,7%), dan beberapa tipe persilangan seperti; Batur x Garut pada jantan (63,6%), Dorper x Garut (64,2% dan 66,7%) dan Garut x Garut (57,8% dan 64,4%) di kedua jenis kelamin anaknya. Sifat tidak bertanduk mendominasi hasil persilangan domba, baik pada anakan jantan maupun betina. Sifat bentuk tanduk, bentuk telinga, dan bentuk ekor pada tipe hasil persilangan merupakan varian fenotip yang membedakan antara persilangan sesama domba Garut dengan persilangan Garut dengan rumpun pejantan berbeda (F1 Dorper, F1 Suffolk dan Batur)., This study aims to identify the phenotypic profile of qualitative traits crosses between ewes Garut and rams from different breeds. The number of samples used in this research was 166 sheep from differences in breed of sheep. Qualitative traits categories had seven indicators for this research, incorporated in fleece colour, fleece pattern, horn shape, ear shape, tail shape, facial profile, and horn colour. The method used in this research was direct observation and analysis by descriptive and account by frequency relatives. The result of research described that the combination of white and black colours earned the highest value on the Garut rams (50%), Dorper rams (100%), Garut ewes (60,7%), and several offsprings of crosses typical such Batur x Garut for male offspring, Dorper x Garut (64,2% and 66,7%) and Garut x Garut (57,8% and 64,4%) for both sex offspring male and female. The trait of polled dominated crosses typical of sheep for male and female offspring. The horn, ear, and tail type were different factors to reveal between Garut and their crosses (F1 Dorper, F1 Suffolk and Batur).

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
