Judul: Ukuran Tubuh Ayam F1 Persilangan Ayam Kampung dengan Ayam Ras Pedaging Umur 0-12 Minggu
Abstrak: The aimed of this research was to know body size of the first crossing chickens (F1) from Kampung x Commercial chicken (KB) and Commercial x Kampung chicken (BK), 0 weeks up to 12 weeks old. There are KB chicken 67 birds and BK chicken 15 birds. Body size of KB and BK chicken was measured every 2 weeks. Research data were analyzed by T test. Variables measured consisted of body weight, wing span, length of the backbone, length of the tibia, length of the femur, length of the shank, length of the breast and breast circumference. Body size and body weight of KB chicken and BK chicken were not significantly different (P>0.05). Body size of KB chicken and BK chicken were higher than chicken kampong. Based of the researh, KB roaster and BK roaster had body size were biggest than KB hen and BK hen. Kampung chicken crossbred with commercial chicken could to increased body weight and body size of KB and BK chicken than Kampung chicken.

Judul: Ukuran Tubuh Ayam Hasil Persilangan Pelung X Sentul Dengan Kampung X Ras Pedaging Pada Umur 12 Sampai 22 Minggu
Abstrak: Penelitian ini bertujuan untuk mengobservasi ukuran tubuh ayam F1 pada fase pertumbuhan (12-22 minggu) dari hasil persilangan ayam pelung sem sentul (PS), ayam kampung ras pedaging (KB) dan ayam ras pedaging kampung (BK) Penelitian ini dilakukan pada bulan Desember 2014 sampai Mei 2015. Total ayam yang digunakan dalam penelitian ini ada 42 ekor yaitu jantan PSKB (12) Betina PKR (9), jantun PSBK (10) dan betina PSBK (8). Peubah yang diamats pada penelitian ini antara lain bobot badan, lingkar dada, panjang zihia, panjang fenner, ilin panjang dada. Uji T digunakan untuk membandingkan bobot hadan dan ukuran tubuh dari dua ayam persilangan. Hasil penelitian ini menunjukkan hohot badin antara jantan dan betina pada umur yang sama dan begitu juga pada ulouran tubuh (lingkar dada, panjang shiu, panjang femar, dan panjang dada) adalah sama antara ayam PSKB dan PSBK…

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.
