Seleksi ayam IPB-D1 berdasarkan pertumbuhan bobot badan yang cepat untuk mendapatkan calon galur ayam IPB-D3 (male line). Penelitian ini bertujuan mengkaji dan mengevaluasi keseragaman bobot badan dan ukuran-ukuran tubuh pada ayam IPB-D3 G2. Penelitian dilakukan pada bulan September 2022 hingga bulan Januari 2023 di Laboraturium Lapang Pemuliaan Genetika Ternak, Fakultas Peternakan, IPB. Peubah yang diamati adalah panjang punggung, panjang leher, panjang sayap, panjang dada, lebar dada, lingkar dada, dalam dada, panjang shank¸lingkar shank, panjang femur, dan panjang tibia. Data dianalisis deskriptif dan uji t. Ukuran tubuh ayam IPB-D3 generasi kedua umur 2 sampai 12 minggu beragam. Koefisien keragaman berkisar antara 5,78% sampai 27,53%, termasuk dalam kategori sedang dan tinggi. Ukuran tubuh yang paling baik untuk menduga pertumbuhan atau bobot badan adalah lingkar dada untuk jantan dan panjang femur untuk betina., An example of a chicken clump that has been made efforts to improve genetic quality is IPB-D1 chicken. IPB-D1 chicken clumps have fast growth and good body resistance to Newcastle Disease (ND) or tetelo and Salmonella sp. IPB-D1 chicken selection is based on rapid weight growth to obtain prospective IPB-D3 (male line) chicken strains. This study aims to examine and evaluate the uniformity of body weight and body measurements in IPB-D3 G2 chickens. The research was conducted from September 2022 to January 2022 at the Field Laboratory of Livestock Genetic Breeding, Faculty of Animal Husbandry, IPB. The observed variables were dorsal length, neck length, wing length, chest length, chest width, chest circumference, inner chest, shank ̧shank circumference, femur length, and tibia length. The data were analyzed descriptively and t-test. The body size of the second generation IPB-D3 chickens aged 2 to 12 weeks varies. The coefficient of diversity ranged from 5.78% to 27.53%, belonging to the medium and high categories. The best variables for estimating growth or body weight are chest circumference for males and femur length for females.

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.
