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: 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 dan Pencirian Natrium Titanat (Na2Ti2O4(OH)2) Berbahan Dasar Titanium Dioksida
Abstrak: TiO2 can be utilized as basic material for synthesis of sodium titanate (Na2Ti2O4(OH)2). This research was purposed to synthesize and characterize sodium titanate from TiO2 rutile powder as a basic material. Sodium titanate was synthesized by hydrothermal process at temperature 130 °C by mixing TiO2 rutile powder with 5 M and 10 M NaOH solution, then each was calcinated at temperature 700 °C. The energy dispersive X-ray analysis showed that sodium titanate has been successfully synthesized. This result was also supported by functional group analysis with Fourier transform infrared (FTIR) spectrofotometer showing the existence of Ti-O-Na vibration band at 989.42 cm-1. The formation of sodium titanate was depend on the reaction condition such as temperature, reaction time, and NaOH concentration. Scanning electron microscope image indicated that sodium titanate synthesized at 130 °C in 20 hours reaction time with 10 M NaOH had crystal size of 99.37 nm.
