Abstrak: Query fever is a zoonotic disease caused by Coxiella burnetii. This agent infects any kinds of animal including cattle. In many cases report, there are no clinical signs appear during the infection of C. burnetii. Then, it is also difficult to diagnose this disease. The study about infection of C. burnetii in cattle was carried out from February to October 2013 at Bogor Slaughterhouse. The aim of this study was to know the infection of C. burnetii and compare the histopathological finding of spleen and heart of infected cattle. A total of 50 samples of cattle spleen, heart, liver, kidney, and lung were collected, and processed for immunohistochemical and hematoxyllin and eosin staining. The result of immunohistochemical staining showed 5 samples were immunoreactive to polyclonal rabbit anti-Coxiella burnetii antibody FKH IPB in the spleen, liver, and kidney. The histopathological finding indicated hemosiderin pigment deposits, lymphoid follicle depletion, infiltration of lymphocyte, macrophage, neutrophil, and eosinophil cells, and oedema. No lesion appeared in heart with positive infection of C. burnetii, however myocardial degeneration, myocardial regeneration, and myocardial congestion were found in heart with negative infection of C. burnetii.

Abstrak: Query fever (Q fever) is a zoonotic disease caused by Coxiella burnetii. Domestic ruminants are considered to be the main reservoir of Q fever. The transmission of this disease usually by aerosol and ingestion. This research was aimed to describe and compare the histopathology on liver, lung, and kidney of cattle infected by C. burnetii using Immunohistochemistry and Hematoxylin Eosin staining. This research used 50 samples and each sample consisted of liver, lung, kidney, heart, and spleen was carried out from February to October 2013 at Bogor slaughterhouse. The result showed that we found 5 samples out of 50 samples were positive infected with C. burnetii Imunohistochemically. Histopathological lesions found like focus inflammation, congestion, haemorrhage, fibrosis, focus necrosis, emphysema, pleuritic, and interstitial pneumonia in positive Q fever samples. Similar histopathological changes were also found in negative Q fever samples.

Abstrak: Growth of films Ba0,5Sr0,5TiO3 (BST) 1 M has been done with variation of annealing in hold time 8 hours, 15 hours, 22 hours, and 29 hours at constant temperature 8500C, above Si (100) substrate p-type, by using the sol-gel process method which followed with spin coating process at 3000 rpm for 30 seconds. Optics spectroscopy shows that BST film solar cells with annealing hold time 8 hours, 15 hours, and 22 hours, works effectively in wavelength ≥ 700 nm absorption range. Yet for sample with annealing hold time about 29 hours effectively absorb in ≤ 700 nm wavelength range. It obtained BST film refractive index at range 2.0 to 7.0 to wavelength range ±370-870 nm. Band gap BST film value based on annealing hold time 8 hours, 15 hours, 22 hours, and 29 hours respectively 2.60 eV; 3.12 eV: 3.24 eV, and 2.66 eV. Electrical conductivity value which obtained, indicate that the BST film is classified as semiconductor material with conductivity order 10-5-10-4 S / cm. The result of I-V photovoltaic characterization shows the BST film potentially to be a solar cells device with efficiency according to the annealing hold time 8 hours, 15 hours, 22 hours, and 29 hours in a row are 2.68x10-5%, 3.51x10-5%, 4.53x10-5% and 3.22x10-5%
