Judul: Sifat-sifat reproduksi ayam pelung di kecamatan Cibeber dan kecamatan Gekbrong Cianjur, Jawa Barat
Abstrak: Pelung chicken is one of Indonesian local chicken, which have spesific traits mainly on male chicken. It have long voice, beautiful and spesific rhytme. It also have heavy body weight and a potential income as chicken meat type. The aimed of this research was to collect information of Pelung's reproductivities in subdistrict Cibeber and Gekbrong, in Cianjur district. The research was conducted in June up to the end of September 2006. Data was collected from 289 heads of Pelung chicken and had been analyzed by using student test.

Judul: Sifat-sifat reproduksi ayam pelung di Kecamatan Cibeber dan Kecamatan Gekbrong Cianjur,Jawa Barat
Abstrak: Ayam Pelung adalah salah satu ayam lokal asli Indonesia yang memiliki keistimewaan pada suara kokoknya, khususnya pada ayam jantan, yang bersuara panjang, merdu dan berirama. Bobot badannya yang besar berpotensi sebagai ayam penghasil daging. Penelitian ini bertujuan mempelajari sifat dan potensi reproduksi ayam Pelung di Kabupaten Cianjur sehingga dapat dijadikan informasi dasar seleksi pada ayam Pelung. Penelitian dilakukan pada awal bulan Juni sampai dengan akhir bulan September 2006, berlokasi di Kecamatan Cibeber dan Kecamatan Gekbrong, Kabupaten Cianjur. Penelitian ini menggunakan ayam Pelung sebanyak 289 ekor yang terdiri dari 40 ekor jantan dewasa, 36 ekor betina dan 73 ekor DOC di Kecamatan Cibeber, 43 ekor jantan dewasa, 38 ekor betina, serta 59 ekor DOC di Kecamatan Gekbrong. Sifat-sifat reproduksi yang diamati dan dianalisis antara lain bobot telur tetas, ukuran telur tetas (panjang dan lebar), indeks telur, bobot tetas, produksi telur dalam satu periode bertelur, daya tetas telur, mortalitas anak, nisbah kelamin dan lama periode bertelur. Data yang diperoleh ditabulasi dan dilakukan analisis statistik, serta disajikan secara deskriptif dan statistik dalam bentuk tabel dengan menggunakan perangkat lunak komputer Minitab V 14.

Judul: Peran Surfaktan Setiltrimetilamonium Bromida dan Natrium Dodesil Sulfat pada Sintesis ZnO dengan Metode Hidrotermal
Abstrak: Zno crystal is the main preference material in various applications recently, such as in semiconductors, ultraviolet lasers, and catalysts. This study aims to synthesize ZnO with addition of surfactant. ZnO crystals were synthesized by reacting ZnSO4, KOH, and surfactants using hydrothermal method. The first step was to determine the best ratio of ZnSO4: KOH (1:2; 1:3; 1:4, and 1:5) based on X-ray diffraction. The second step was to evaluate the role of surfactan cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) on the synthesis of ZnO crystals. The result of this study showed the best ratio of ZnSO4:KOH was 1:3, based on the least of impurities and the highest degree of crystallinity (85.64%). The addition of surfactant CTAB and SDS in the synthesis of ZnO increased the degree of crystallinity, which were 98.28% and 92.17%, respectively. Based on mathematical calculation using Scherrer equation, the crystal size without surfactant was 32 nm, whereas with CTAB and SDS the crystallited size were 28 nm and 29 nm, respectively. The degree of crystallinity and crystal size indicated that CTAB surfactant produce ZnO crystals with the best characteristics as compared to SDS surfactant or without surfactant.
