Judul: Prevalensi, Derajat Infeksi, dan Faktor Risiko Infeksi Parasit Darah pada Sapi Potong di Kecamatan Cikalong, Tasikmalaya
Abstrak: This research was aimed to determine the prevalence, intensity of infection, and risk factors of blood parasite infection in cattle of Cikalong subdistrict, Tasikmalaya. Blood smears samples collected from 114 cattle in Cikalong subdistrict and processed using Giemsa staining method. Quantitative evaluation of parasitemia (percentage of infected RBCs) was assesed by counting of the number of parasite erythrocytes present per 500 cells at a magnification of 1000×.The potential of risk factor in regard with livestock management were obtained by interviewing the farmer. The result showed that the highest prevalence rate of blood parasite was Theileria sp. (60.53%), followed by Babesia sp. (44.74%) and Anaplasma sp. (30.70%). Based on sex, the mean of blood parasite in bull was higher than cow. Babesia sp. and Theileria sp. infection in cow was significantly than bull (p<0.05), while Anaplasma sp. infection was not significantly (p>0.05). Based on age, the mean of blood parasite in cattle (>12 month) was higher than calf (<12 month). Babesia sp. and Anaplasma sp. infection in cattle was not significantly than calf (p>0.05), while Theileria sp. infection was significantly (p<0.05). Generally, the prevalence rate of blood parasite was influenced by livestock management, feeding, and vector control was not significantly (p>0.05).

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.

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.
