Judul: Morphometric Characteristics of Male Rabbits at Different Ages and Breeds Supervised
Abstrak: Kelinci hyla dan hycole merupakan kelinci pedaging unggul yang baru dikembangkan di Indonesia. Penelitian ini bertujuan untuk membandingkan perbedaan morfometrik kelinci hyla dan hycole di Peternakan Kelinci Azhar Farm Indonesia Batu Malang, Jawa Timur. Penelitian menggunakan 40 ekor kelinci pedaging yang terdiri atas 20 ekor Hyla dan 20 ekor Hycole dengan umur 1-5 bulan. Rancangan yang digunakan adalah Rancangan analisis deskriptif. Variabel yang diukur adalah lingkar dada (DFS), lebar dada (CW), lebar dada (CW), panjang kaki depan/panjang segmen ulna (USL), panjang kaki depan/humerus (UF), panjang tungkai/tibia punggung bawah/bawah kembali. (LL), Punggung Atas / Femur (UPL), Punggung Panjang (LB), Punggung Lebar (WB) dan Berat Badan (BB). Hasil penelitian menunjukkan umur memiliki pengaruh nyata (P<0,05) terhadap setiap variabel yang diukur kecuali variabel lingkar dada dan ulna yang tidak memiliki pengaruh nyata(P>0,05). Sedangkan pada interaksi rumpun dan umur tidak berpengaruh nyata pada setiap variabel kecuali variabel lingkar dada dan ulna

Judul: Performa Kelinci New Zealand White, Hycole dan Persilangan pada Peternakan Kelinci Arnabun di Kecamatan Ciomas Kabupaten Bogor
Abstrak: Penelitian ini bertujuan mengkaji performa kelinci New Zealand White, Hycole dan silangan di peternakan kelinci Arnabun meliputi performa reproduksi induk kelinci yang telah beranak dan ukuran tubuh kelinci jantan berumur diatas 6 bulan. Penelitian menggunakan kelinci New Zealand White (3 ekor betina dan 22 ekor jantan), Hycole (10 ekor betina dan 7 ekor jantan) serta silangan (5 ekor betina). Data dianalisis menggunakan rancangan acak lengkap dan uji lanjut Duncan multiple range test. Reproduksi untuk umur pertama dikawinkan pada induk kelinci silangan lebih baik (P<0,05) dibandingkan Hycole dan New Zealand White, yaitu sebesar 159,6±33,9 hari, 176,0±26,8 hari dan 232,7±4,7 hari. Sifat service per conception, lama bunting, jumlah anak sekelahiran dan lama waktu dikawinkan kembali tidak berbeda (P>0,05). Bobot badan jantan kelinci New Zealand White dan Hycole tidak berbeda, Hycole lebih tinggi ukuran panjang kepala, panjang dan lebar telinga serta panjang tulang punggung dibanding New Zealand White, tetapi New Zealand White memiliki ukuran dalam dada, lebar dada, panjang tulang femoris dan lebar panggul lebih tinggi dibanding Hycole. Kelinci New Zealand White memiliki tipe tubuh compact dan Hycole bertubuh commercial yang termasuk tipe kelinci pedaging., This study aims to assess the performance of New Zealand White, Hycole and crossbreed rabbits at Arnabun rabbit farm includes rabbit reproductive performance of doe’s which had partus and body size in buck’s over 6 months old. The study used New Zealand White rabbits (3 doe’s and 22 buck’s), Hycole (10 doe’s and 7 buck’s) and crossbreeds (5 doe’s). Data were analyzed using a completely randomized design and Duncan multiple range test. Reproduction on age at first mating of crossbreed rabbits was better (P<0,05) than Hycole and New Zealand White at 159,6±33,9 days, 176,0±26,8 days and 232,7±4,7 days, respectively. The traits of service per conception, length of gestation, number of litter size at born and length of time mated again were not different (P>0,05). Male body weights of New Zealand White and Hycole rabbits were not different, Hycole had higher head length, ear length and width, and backbone length than New Zealand White, but New Zealand White had higher chest depth, chest widht, femoral bone length and pelvic width than Hycole. New Zealand White rabbits have a compact body type and Hycole have a commercial body type which includes broiler rabbits.

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.
