Judul: Prevalensi parasit darah (Babesia sp. Theileria sp.) pada ternak sapi rakyat di lima kecamatan, Kabupaten Lampung Tengah
Abstrak: Sampel darah diambil dari 178 sapi lokal (Bali, Peranakan Ongole, Brahman, Prambon dan Brangus) yang berumur 1-7 tahun di lima kecamatan wilayah Kabupaten Lampung Tengah Propinsi Lampung dari bulan Agustus 2001 sampai Maret 2002. Sampel darah diperiksa untuk mengetahui adanya parasit darah yaitu Babesia sp. dan Theileria sp. Sampel darah diwarnai dengan pewarna Giemsa dan diperiksa dengan menggunakan mikroskop. Hasil yang didapat menunjukkan bahwa hewan yang terinfeksi Babesia sp. dan Theileria sp. rata-rata sebesar 0,356 % dan 2,08%, dengan persentase sapi yang terinfeksi Babesia sp. paling tinggi ditemukan di Kecamatan Punggur yaitu sebesar 0,150% dan paling rendah di Kecamatan Seputih Mataram sebesar 0,026 %. Persentase sapi yang terinfeksi Theileria sp. paling banyak di Kecamatan Sendang Agung yaitu sebesar 0,845 %dan paling sedikit di Kecamatan Seputih Raman sebesar 0,144 %. Managemen diperkirakan faktor utama yang mempengaruhi prevalensi dibandingkan dengan faktor iklim….

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: Peran Surfaktan Setiltrimetilamonium Bromida dan Natrium Dodesil Sulfat pada Sintesis ZnO dengan Metode Hidrotermal
Abstrak: Zno crystal is the main preference material in various applications recently, such as in semiconductors, ultraviolet lasers, and catalysts. This study aims to synthesize ZnO with addition of surfactant. ZnO crystals were synthesized by reacting ZnSO4, KOH, and surfactants using hydrothermal method. The first step was to determine the best ratio of ZnSO4: KOH (1:2; 1:3; 1:4, and 1:5) based on X-ray diffraction. The second step was to evaluate the role of surfactan cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) on the synthesis of ZnO crystals. The result of this study showed the best ratio of ZnSO4:KOH was 1:3, based on the least of impurities and the highest degree of crystallinity (85.64%). The addition of surfactant CTAB and SDS in the synthesis of ZnO increased the degree of crystallinity, which were 98.28% and 92.17%, respectively. Based on mathematical calculation using Scherrer equation, the crystal size without surfactant was 32 nm, whereas with CTAB and SDS the crystallited size were 28 nm and 29 nm, respectively. The degree of crystallinity and crystal size indicated that CTAB surfactant produce ZnO crystals with the best characteristics as compared to SDS surfactant or without surfactant.
