Judul: Infeksi Parasit Darah pada Sapi Perah di Kawasan Usaha Ternak (KUNAK) Cibungbulang, Kabupaten Bogor
Abstrak: Kasus penyakit yang disebabkan oleh parasit darah umumnya bersifat kronis, namun pada beberapa kasus ada yang bersifat akut. Kerugian ekonomi yang disebabkan oleh penyakit parasit darah dapat berupa pertumbuhan terhambat, penurunan bobot badan, penurunan daya reproduksi, penurunan produksi susu, dan abortus. Penelitian ini bertujuan untuk mengetahui keberadaan parasit darah dan tingkat parasitemia pada sapi perah di kawasan usaha ternak (KUNAK) Cibungbulang, Kabupaten Bogor. Terdapat 100 sampel darah sapi perah dalam penelitian ini yang terdiri dari 21 sampel dari kelompokm umur ≤ 2 tahun dan 79 sampel dari kelompok umur >2 tahun. Variabel yang diamati adalah presentase hewan yang terinfeksi dan tingkat infeksi dengan mengetahui persentase parasitemia. Hasil penelitian dari 100 sampel ditemukan 69 ekor yang terinfeksi (69%). Ada 3 jenis parasit darah yang ditemukan dalam penelitian ini yaitu Babesia sp., Anaplasma sp. dan Theileria sp.. Persentase hewan terinfeksi parasit tertinggi yaitu Theileria sp. (50%), kemudian Anaplasma sp. (15%) dan terendah Babesia sp. (4%).Persentase parasitemia pada berbagai tingkat umur memiliki nilai sama yaitu kurang dari 1%, yang tergolong dalam tingkat parasitemia rendah

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.
