Judul: Karakteristik morfologi ayam pelung dewasa diKecamatan Cibeber dan Gekbrong Kabupaten Cianjur, Jawa Barat
Abstrak: Pelung chicken as one of local chicken in Indonesia that have specificity, especially on male chicken which long voice, beautiful, and specific rhyme. The male of Pelung chicken have heavier body weight than any other male chicken. It show a potential characteristic as meat type chicken. The purpose of this research was to collect information of specific morphological characteristic of Pelung chicken in Cianjur. The research was conducted in subdisdricts of Cibeber and Gekbrong in two months, from May up to the end of Juty 2006. Data were collected from 63 heads of Pelung males and 37 heads of hens in Cibeber, a9 heads Pelung males and 50 heads of hens in Gekbrong. The morphological chracteristic of Pelung chicken was analyzed by using Principal Component Analysis (PCA). The result of Principal component Analysis showed that males Pelung chicken in the subdistrict of Geicbmng had bigger body size than Pelung chicken in the subdistrict of Cibebe7, while body shape- was similar. Body size of male Pelung chicken could be identified by chest circumference, while body shape by femur and neck lenght Size and shape of female Pelung chicken in two subdistrict were different Body size of female pilung chicken were identified by wing lenght and ched circumferenced, while body shape by neck lenght Keyword : Pelung chicken, morphology, Principal Component Analysis.

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: 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.
