Abstrak: Setiap tahun Indonesia mengimpor sapi dan daging dari Australia. Australia merupakan negara pertama ditemukannya penyakit Query fever (Q fever) pada pekerja rumah potong hewan dan sampai sekarang masih bersifat endemik. Q fever merupakan salah satu penyakit yang dapat ditularkan melalui makanan (foodborne disease) dan dikategorikan sebagai emerging infectious disesase yang bersifat zoonosis. Penyakit ini disebabkan oleh Coxiella burnetii (C. burnetii) yang bersifat obligat patogen intraseluler, pleomorfik, tahan terhadap kondisi psikokimia dan berpotensi digunakan sebagai senjata biologis. Penularan ke manusia terjadi melalui inhalasi partikel debu yang berasal dari feses, urin dan wol yang terinfeksi; kontak langsung dari hewan atau jaringan terinfeksi seperti sisa abortus, plasenta dan darah serta melalui saluran pencernaan karena mengkonsumsi susu dan telur yang tidak dipasteurisasi. Orang yang terinfeksi penyakit Q fever akan memperlihatkan gejala klinis seperti flu (flu like syndrome), pneumonia dan hepatitis. Apabila tidak segera diobati dengan baik sekitar 2-10% akan menjadi endokarditis. Kematian pada kasus kronis dapat mencapai 25-65%, sehingga dari kesehatan masyarakat veteriner perlu mendapatkan perhatian yang serius.

Judul: Kajian Q fever pada Sapi Perah Impor dari Australia yang Masuk Melalui Bandar Udara Soekarno-Hatta
Abstrak: Q fever is worldwide distributed zoonosis caused by Coxiella burnetii. This intracelluar bacterium infects a wide range of animals and associated with reproductive disorders in domestic ruminants. It can lead an acute and chronic infections and caused flu-like syndrome, hepatitis, pneumonia or endocarditis. The aim of this research is to study Q fever in imported dairy cattle from Australia through the Soekarno-Hatta airport. Forty-six samples of serum and whole blood were taken from imported dairy cattle. Two diagnostic methods used in this study were serological test using enzyme-linked immunosorbant assay (ELISA) and nested polymerase chain reaction (nested PCR). The result of serological test showed that 23 (50%) out of 46 samples were positive but Coxiella burnetii DNA were not detected by nested PCR. These data revealed that Q fever have infected imported dairy cattle from Australia through Soekarno-Hatta airport with 50% of seroprevalence.

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.
