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: Adsorpsi–fotodegradasi Biru Metilena oleh Nanokomposit Kaolin/TiO2 yang Diemban dengan ZnO
Abstrak: Synthetic dye waste such as methylene blue pollutes aquatic evironment. Kaolin/TiO2 nanocomposite was made for adsorption–photodegradation process under UV light. The nanocomposite was prepared by paste and ball milling methods. Semiconductor ZnO was used as dopant to ease photodegradation in visible-light range. X-ray diffraction results showed that kaolin/TiO2 and kaolin/TiO2/ZnO nanocomposites were successfully made. However, ZnO doping decreased crystallinity of the nanocomposites. Scanning electron microscopy results showed that the surface morphology of the nanocomposite made by using paste method and that of doped nanocomposite made by using ball milling method were different. ZnO doping increased the adsorption capacity of the nanocomposite. Photodegradation results showed that ZnO doping improved the photocatalytic activity of the nanocomposites under UV and visible irradiation. However, the photocatalytic activity of the nanocomposites was relatively better under UV irradiation than that under the visible irradiation.
