Judul: Pengaruh Infestasi Parasit Darah (Anaplasma sp., Theileria sp., dan Babesia sp.) pada Nilai Leukosit Kuda (Equus caballus
Abstrak: This study was made to observe the effect of blood parasite (Anaplasma sp., Theileria sp., and Babesia sp.) on leukocyte value in horse. The blood samples were taken from 6 crossbred horses (3 male and 3 female) positively infected by blood parasite (Anaplasma sp., Theileria sp., and Babesia sp.) with variant age (2-10 years old) in URR, Faculty of Veterinary Medicine, Bogor Agricultural University. Blood samples were taken every 2 weeks for 2 months. The blood leukocyte value were analyzed using variance analysis (ANOVA). Average of Anaplasma sp., Theileria sp., and Babesia sp. in those horses was 1.05%, 1.01%, and 0.68%, respectively. Horses with mild parasitemia were not show clinical sign and potentially become parasite carrier. Based on the research the mild infestation of blood parasite (Anaplasma sp., Theileria sp., and Babesia sp.) was not significantly influence the leukocyte value.

Judul: Parasitemia Dan Diferensial Leukosit Akibat Infeksi Parasit Darah Pada Kerbau (Bubalus Bubalis) Di Kabupaten Bogor
Abstrak: The aim was to identifiy the type of blood parasites that attack in buffaloes (Bubalus bubalis), to determine blood parasites percentage, parasitemia rate based on the leukocyte differential of the buffaloes in Bogor. The Blood samples were collected from 14 buffaloes using blood smear method.Samples were processed in glass slide, stained with Giemsa 10% and were observed using a microscope with 1000x magnification.The parasitaemia were counted for every 500 red blood cells. The result showed buffaloes infections were caused by Anaplasma sp., Theileria sp, and Babesia sp. The highest parasitemia rate was caused by the infection of Theileria sp.which was 43%, followed by the infection of Anaplasma sp. which was 36%, 7% of double infections which were (Anaplasma sp., Theileria sp.), (Theileria sp., Babesia sp..), and the triple infections 7% (Anaplasma sp., Theileria sp., Babesia sp.). Although the parasitemia rate of the single infection Anaplasma sp. and Theileria sp. showed significant differences (P<0.05), hence, the buffaloes are still in the severity of mild diseases. The leukocyte differential showed the differences in every infection. The double infections (Anaplasma sp., Theileria sp.) and (Theileria sp., Babesia sp.) had the highest lymphocyte count whereas the triple infections (Anaplasma sp., Theileria sp., Babesia sp.) had the highest neutrophil count. The significant differences of the eosinophil count were showed on the single infections Anaplasma sp. and Theileria 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.
