Judul: Studi keragaman fenotipik dan jarak genetik antar domba garut di BPPTD Margawati (Garut), Lesan Putra (Ciomas, Bogor) dan ternak domba sehat (Cinagara, Bogor)
Abstrak: The morphological discriminant and canonical analysis were carried out to estimate the genetic distance and determine the discriminant variable among Garut sheep from BPPTD Margawati (Garut), Lesan Putra (Ciomas, Bogor) and Ternak Domba Sehat (Cinagara, Bogor). The number of sheep used totally 224 heads conected from 3 populations, Margawati (97 heads), Ciomas (59 heads) and Cianagara (68 heads).

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: 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.
