Judul: Studi Kasus Infeksi Parasit Darah pada Sapi Potong di Kabupaten Subang, Jawa Barat
Abstrak: This study describes prevalence of blood parasites and parasitemia level using blood smear. Result of the experiment of blood samples in 62 cattle from Subang Regency showed a blood parasite infection by Babesia sp., Theileria sp., and Anaplasma sp. The inapposite maintenance management was thought to be main factor causing infection. This supported by hipotesis chi square test which states, that maintenance management relates to prevalence. In this research, also performed calculations average parasitemia to measure level of parasitosis by age level and gender cattle. The calculations show parasitosis level mild because obtained average parasitemia <1%. Statistical tests average parasitemia (Babesia sp., Theileria sp., and Anaplasma sp.) age level significantly different (p<0.05) in calf and adult cattle. By sex were also obtained significantly different results (p<0.05) in bulls and cows for blood parasites Anaplasma sp.

Abstrak: The purpose of this study was to determine the prevalence, risk factor and parasitemia blood parasite based on age and sex category on cattle in Ujungjaya sub-district, Sumedang regency, West Java. Blood samples were collected from 139 cattle in July 2012. Thin blood smears were made on glass slide, fixed in methanol, stained with Giemsa 10% and observed using a microscope with 1000x magnifications. The amount of intraerythrocytic parasite counted for every 500 red blood cells. The potential of risk factor in regard with age, sex, ways to raise, flies and tick control were analyzed with chi-square. The result showed that the highest prevalence was observed in Anaplasma sp. (38.8%), followed by Babesia sp. (33.8%), and Theileria sp. (22.3%). The prevalence of babesiosis and anaplasmosis are influenced by age and ways to raise (p<0.05), while theileriosis had not significantly different. Sex did not affect the level of prevalence. The prevalence of babesiosis is influenced by flies and tick control (p<0.05), while anaplasmosis and theileriosis did not differ significantly. In general, the level of parasitemia increased along with increasing by age. The parasitemia of babesiosis in cow had differently with bull (p<0.05), while anaplasmosis and theileriosis had not significantly different. Percentage parasitemia at various age and sex have the same value that is <1%, which is relatively mild levels of parasitemia.

Judul: Sintesis Nanorod Seng Oksida (ZnO) dengan Metode Sonokimia
Abstrak: Gelombang ultrasonik telah digunakan untuk membantu sintesis ZnO. ZnO terbentuk dari campuran ZnAc dan NaOH. ZnO disintesis dengan variasi konsentrasi ZnAc 0.5 M ( ZnO 1:1 ) dan 1.5 M ( ZnO 3:1 ) yang dicampurkan dengan NaOH konsentrasi 0.5 M. Sampel yang diporoleh dikarakterisasi dengan XRD dan SEM. Karakterisasi difraksi sinar-X menunjukkan bahwa struktur kristal ZnO yang dihasilkan merupakan heksagonal dengan pertumbuhan yang dominan pada orientasi bidang nonpolar a dengan indeks hkl 101. Kristalinitas dan kemurnian kristal ZnO 1:1 lebih baik dibandingkan ZnO 3:1 ditunjukan dengan intensitas puncak difraksi sinar-X yang lebih tinggi, sempit dan tajam. Untuk ukuran kristalit ZnO 1:1 mempunyai rata-rata ukuran kristalit 30.57 ± 4.31 nm sedangkan ZnO 3:1 mempunyai ukuran rata-rata 20.25 ± 7.12 nm. Dari ukuran kristal yang terbentuk partikel ZnO termasuk nanokristal. ZnO 1:1 terbentuk batang-batang nano (nanorods) sedangkan pada ZnO 3:1 tidak terbentuk batang-batang nano (nanorods). Untuk ukuran morfologi, ZnO 1:1 mempunyai rata-rata ukuran butiran kristal 230 nm dan lebih besar dibandingkan ukuran ZnO 3:1 yang mempunyai rata-rata ukuran butiran kristal 50 nm.
