Judul: MORPHOMETRIC OF INTERSE MERAWANGARAB AND ARABMERAWANG CHICKEN CROSS FIFTH GENERATION AT AGE 2  TO 12 WEEKS
Abstrak: Penelitian ini mengkaji morfometrik hasil persilangan ayam merawangarab generasi kelima pada umur 2 sampai 12 minggu. Persilangan menggunakan 4 jenis ayam generasi kelima dengan komposisi genetik ayam merawang (M) pada ayam persilangan merawangarab yaitu 25% M, 50 % M, 62,5% M, dan 75% M. Peubah yang diamati meliputi panjang punggung, panjang sayap, lingkar dada, panjang dada, lebar dada, dalam dada, panjang femur, panjang tibia, panjang shank, dan lingkar shank. Pengukuran peubah dilakukan 2 minggu sekali. Penelitian ini menggunakan rancangan acak kelompok. Uji statistik memperlihatkan perbedaan nyata untuk panjang punggung pada ayam umur 6-12 minggu. Panjang punggung menunjukkan perbedaan sangat nyata pada ayam umur 6 dan 8 minggu. Panjang femur berbeda nyata pada umur 2 minggu dengan nilai rataan tertinggi ayam 62,5% M yaitu 31,863±4,443 mm. Analisis statistik menunjukkan ayam umur 2 minggu menunjukkan perbedaan sangat nyata pada ayam komposisi genetik 50% M dan 62,5% M. Peningkatan pertumbuhan ukuran tubuh ayam merawangarab menunjukkan pertumbuhan untuk semua komposisi genetik dari umur 2-12 minggu. Ayam merawangarab dengan komposisi genetik 62,

Chickens Age 2 to 12 Weeks with Different Feed Percentages
Abstrak: AGUS SRI WIDODO. Morfometrik Ayam Merawangarab Generasi Keempat Umur 2 Sampai 12 Minggu dengan Persentase Pakan Berbeda. Dibimbing oleh SRI DARWATI dan IYEP KOMALA. Ayam lokal merupakan sumber daya genetik yang sangat berharga yang perlu dilestarikan dan dikembangkan. Penelitian ini mengkaji morfometrik ayam merawang arab generasi keempat dengan komposisi pakan konsentrat 80%, dedak 20%, dan konsentrat 100%. Peubah yang diamati pada penelitian ini adalah panjang shank, panjang femur, panjang tibia, panjang dada, panjang punggung, panjang sayap, lingkar shank, lingkar dada, lebar dada, dan dalam dada ayam merawangarab dengan komposisi pakan konsentrat 80% dan 100% tidak berbeda nyata pada umur 2-12 minggu. Rata-rata panjang dada ayam dengan komposisi konsentrat 80% dan 100% tidak berbeda nyata pada umur 2-8 minggu, namun berbeda nyata pada umur 10-12 minggu. Rata-rata panjang dada ayam dengan komposisi konsentrat 80% dan 100% umur 10 minggu berturut-turut adalah 85,15±6,01 mm dan 80,70±6,42 mm, sedangkan umur 12 minggu masing-masing 92,97±5,44 mm dan 88,44±6,08 mm. Ayam merawangarab dengan komposisi pakan 80% konsentrat, 20% dedak, dan 100% konsentrat mempunyai ukuran tubuh yang sama., AGUS SRI WIDODO. Morphometrics of Fourth Generation Merawangarab Chickens Age 2 to 12 Weeks with Different Feed Percentages. Supervised by SRI DARWATI and IYEP KOMALA. Local chickens are a very valuable genetic resource that needs to be preserved and developed. This study examines the morphometrics of the fourth generation of merawangarab chickens with a feed composition of 80% concentrate, 20% bran, and 100% concentrate. The variables observed in this study were shank length, femur length, tibia length, chest length, back length, wing length, shank circumference, chest circumference, chest width, and chest depth of merawangarab chickens with a feed composition of 80% and 100% concentrate were not significantly different at the age of 2-12 weeks. The average chest length of chickens with a concentrate composition of 80% and 100% was not significantly different at the age of 2-8 weeks, but was significantly different at the age of 10-12 weeks. The average breast length of chickens with a composition of 80% and 100% concentrate at 10 weeks of age was 85.15±6.01 mm and 80.70±6.42 mm, respectively, while at 12 weeks of age it was 92.97±5.44 mm and 88.44±6.08 mm, respectively. Merawangarab chickens with a feed composition of 80% concentrate, 20% bran, and 100% concentrate had the same body size.

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.
