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: Query fever is a zoonosis that caused by Coxiella burnetii. This infection agents came infect any animals, especially cattle. Q fever is a subclinical disease and usually spread by inhalation route. The aim of the research was to find out the information about histopathological changes of Q fever by Hematoxylin and Eosin staining. Research was conducted from January to September 2013. The sample consists of liver, lung, heart, and spleen taken from 50 cattles at Cibinong slaughterhouse. Confirmation of Q fever diagnosis cattles was done by Immunohistochemistry staining to liver, lung, spleen and heart organ. The result showed that 9 of 50 cattles were infected by C. burnetii immunohistochemically. Histopathological changes of liver and lung were not much different between those infected and not infected cattles.

Judul: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
