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: 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: 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.
