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.

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.

Judul: Karakteristik lompatan hidrolik terhadap pelimpah terjunan pada saluran segi empat
Abstrak: Aliran dengan kecepatan tinggi dalam kondisi superkritis yang melintasi bangunan pelimpah, sebelum bergerak lebih jauh ke arah hilir saluran dimana bilangan Froude (F) lebih besar dari satu harus diubah menjadi aliran subkritis dimana bilangan Froudenya lebih kecil dari satu. Aliran yang meninggalkan kaki pelimpah merupakan aliran yang memiliki kandungan energi yang amat berarti sehingga dapat menimbulkan pengikisan yang besar. Pengubahan bilangan Froude dari kondisi superkritis ke subkritis dimaksudkan agar terjadi perubahan kandungan energi, sehingga aliran menjadi non erosive. Agar daya erosive aliran dapat berkurang, maka biasanya pada bagian hilir dari bangunan pelimpah dibuatkan suatu bangunan peredam energi. Erosi yang terjadi di hilir bangunan pelimpah dapat disebabkan dari keberadaan bangunan pelimpah itu sendiri, maupun bangunan peredam energi yang kurang tepat. Hal ini terutama menyangkut beberapa kejadian lompatan hidrolik yang timbul pada bangunan peredam energi tersebut.. Suatu metode yang efektif untuk menjamin bahwa lompatan hidrolik selalu terjadi pada daerah yang dilindungi, adalah dengan menggunakan bangunan peredam energi yang terdiri dari beberapa tipe dengan..dst
