Judul: Body Morphometric of IPB-D2 Chicken Third Generation Ages 2 to 12 Weeks
Abstrak: Ayam lokal memiliki potensi untuk dikembangkan di Indonesia. Ayam IPBD1 merupakan rumpun baru ayam lokal yang sedang dikembangkan untuk mendapatkan produktivitas yang baik. Ayam IPB-D1 memiliki daya adaptasi terhadap lingkungan cukup baik dan ketahanan tubuh yang baik terhadap penyakit Newcastle Disease (ND) atau tetelo dan salmonellosis. Oleh karena itu, dilakukan seleksi ayam IPB D-1 berdasarkan immunocompletence untuk membentuk calon galur ayam IPB-D2 (female line). Tujuan dari penelitian ini adalah untuk mengkaji dan mengevaluasi keseragaman bobot badan dan ukuran-ukuran tubuh pada ayam IPB-D2 G3. Jumlah ayam yang digunakan sebanyak 100 ekor. Penelitian dilakukan pada bulan September 2021 hingga bulan Januari 2022 di Laboraturium Lapang Pemuliaan Genetika Ternak, Fakultas Peternakan, IPB. Peubah yang diamati adalah panjang punggung, panjang dada, lebar dada, lingkar dada, dalam dada, panjang shank¸lingkar shank, panjang femur, dan panjang tibia. Data dianalisis deskriptif dan uji t. Hasil penelitian menujukkan ayam IPB-D2 G3 memiliki koefisien keragaman tinggi. Laju pertumbuhan ayam IPB-D2 G3 cenderung fluktuatif

Judul: Morphometric of IPB-D3 Chicken First Generation Ages 2 to 12 Weeks
Abstrak: Rumpun ayam IPB-D1 adalah contoh rumpun ayam yang telah dilakukan upaya peningkatan mutu genetik. Rumpun ayam IPB-D1 memiliki pertumbuhan yang cepat dan ketahanan tubuh yang baik terhadap penyakit Newcastle Disease (ND) atau Tetelo dan Salmonella sp. Seleksi ayam IPB-D1 berdasarkan pertumbuhan bobot badan yang cepat untuk mendapatkan calon galur ayam IPB-D3 (male line). Tujuan dari penelitian ini untuk menilai ukuran tubuh ayam IPB-D3 generasi pertama umur 2 sampai 12 minggu. Jumlah ayam yang digunakan sebanyak 6 jantan dan 34 betina indukan sedangkan untuk anakan yaitu 10 jantan dan 52 betina. Data dianalisis deskriptif dan uji t. Ukuran tubuh ayam IPB-D3 generasi pertama umur 2 sampai 12 minggu tidak memiliki perbedaan yang nyata bila dibandingkan dengan ukuran tubuh ayam IPB-D1 generasi ketujuh. Koefisien keragaman berkisar antara 3,42% sampai 11,13% dan termasuk dalam kategori sedang. Peubah yang paling baik untuk menduga pertumbuhan atau bobot badan adalah panjang dada dengan nilai korelasi 0,987 untuk jantan dan 0,988 untuk betina., Strain of IPB D-1 is a local example of chicken that has made an effort to improve mutual genetics. Strain of IPB-D1 has rapid growth and adaptability and against Newcastle Disease or tetello and Salmonella Sp. Selected IPB-D1 chickens based on growth of bodies to get the next generation of IPB-D3 (male line). The purpose of this study was to assess the body size of the first generation of IPB-D3 chickens aged 2 to 12 weeks. The number of chickens used were as many as 6 males and 34 females, 10 males and 52 females. The data were analyzed by descriptive test and t test. The body size of the first generation IPB-D3 chickens aged 2 to 12 weeks did not have a significant difference when compared to the body size of the seventh generation IPB-D1 chickens. The coefficient of variation ranges from 3.42 to 11.13%. This value is included in the medium category. The best variable for predicting growth or body weight was chest length with a correlation value of 0.987 for males and 0.988 for females.

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.
