Judul: Productivity and Egg Quality in crosses of IPB-D2 Chicken with IPB D-3 Chicken and Their Reciprocals
Abstrak: IPB D1 chickens resulted from the selection of crossbreeds from three local chicken breeds of pelung, sentul, kampung, and meat-type breeds. IPB D1 chickens were selected into IPB-D2 and IPB-D3 chickens. IPB-D2 chickens were selected based on the selection of good body resistance against diseases. IPB-D3 chickens were selected based on the selection of fast body weight growth. The research on productivity and egg quality of crossed IPB-D2 chickens with IPB-D3 chickens and their reciprocals. The research used t-test analysis to compare parameters between the two crosses. The material used was 36 tails consisting of 15 females and 3 males in the two crosses. Egg production of both crosses was categorized as good. Quality of the eggs was rated II (good). Reproduction was categorized as good. Crossing differences were affect on egg length, shell thickness, weight percentage of white and yolk (P, Ayam IPB D1 merupakan hasil seleksi persilangan dari tiga jenis ayam lokal yaitu ayam pelung, sentul, kampung, dan tipe daging. Ayam IPB D1 diseleksi menjadi ayam IPB-D2 dan IPB-D3. Ayam IPB-D2 dipilih berdasarkan seleksi ketahanan tubuh yang baik terhadap penyakit. Ayam IPB-D3 dipilih berdasarkan seleksi pertumbuhan bobot badan yang cepat. Penelitian mengenai produktivitas dan kualitas telur pada silangan ayam IPB-D2 dengan ayam IPB-D3 serta resiprokalnya. Penelitian menggunakan analisis uji-t untuk membandingkan parameter antara kedua silangan. Bahan yang digunakan yaitu 36 ayam indukan yang terdiri dari 15 betina dan 3 jantan pada kedua persilangan. Produksi telur kedua persilangan termasuk dalam kategori baik. Kualitas telur termasuk dalam nilai mutu II (baik). Reproduksi ayam termasuk dalam kategori baik. Perbedaan persilangan berpengaruh pada panjang telur, tebal kerabang, persentase bobot putih dan kuning telur (P

Judul: Performa Produksi Hasil Silangan Ayam IPB D2 dengan Ayam IPB D3 serta Resiprokalnya pada Umur 1 Sampai 12 Minggu di SHF
Abstrak: Persilangan antara ayam IPB D2 dengan ayam IPB D3 dan resiprokalnya dilakukan untuk menghasilkan keturunan dengan performa pertumbuhan yang baik. Penelitian ini bertujuan mengkaji performa produksi hasil persilangan antara ayam IPB D2 dengan ayam IPB D3 dan resiprokalnya. Penelitian dilakukan di peternakan Sinar Harapan Farm sebagai salah satu tempat pengembangan ayam IPB-D. Jumlah anak ayam hasil silangan IPB D2 x IPB D3 dan IPB D3 x IPB D2 masing-masing sebanyak 27 ekor dan 48 ekor. Pengambilan data dilakukan setiap minggu. Peubah yang diamati meliputi bobot badan, pertambahan bobot badan, konsumsi pakan, konversi pakan, dan mortalitas. Data yang diperoleh dianalisis deskriptif, selanjutnya dilakukan uji T. Hasil penelitian menunjukkan bobot badan jantan pada umur 12 minggu pada ayam IPB D2 x IPB D3 (1104,22 g) dan betina pada ayam IPB D3 x IPB D2 (975,55 g). Konsumsi pakan dan konversi pakan paling efisien ditunjukkan oleh ayam jantan dari silangan IPB D2 x IPB D3 dan ayam betina dari silangan IPB D3 x IPB D2. Kedua jenis ayam silangan ini memiliki performa baik dan berpotensi untuk dikembangkan sebagai ayam lokal pedaging di daerah pedesaan terutama di sekitar lingkungan SHF., Crosses between IPB D2 chickens and IPB D3 chickens were conducted to produce offspring with good growth performance. This study aimed to assess the production performance of the results of crosses between IPB D2 with IPB D3 and their reciprocals. The research was conducted at Sinar Harapan Farm as one of the IPB-D chicken development sites. The number of chicks from IPB D2 x IPB D3 and IPB D3 x IPB D2 crosses were 27 and 48 respectively. Data were collected every week. The observed variables included body weight, body weight gain, feed consumption, feed conversion, and mortality. The data obtained were analyzed descriptively, followed by T-Test. The results showed that body weight of males at the age of 12 weeks was owned by IPB D2 x IPB D3 chickens (1104,22 g) and females were owned by IPB D3 x IPB D2 chickens (975,55 g). The most efficient feed consumption and feed conversion were shown by IPB D2 x IPB D3 roosters and IPB D3 x IPB D2 hens. Both of these chickens have good performance and are potentially to be grown in rural areas, especially around the SHF neighborhood.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
