Abstrak: This study was conducted to identify the mite that cause mange to local stray cats found around Bogor Agricultural University, Dramaga. The skin scraping from seven cats with pruritus, alopecia, and hyperkeratosis were examined microscopically. Two of seven cats, two showed Otodectes sp. on their skin scraping examination. Otodectes were found on ear and head area. The mites can be found outside the ear, as the natural habitat for Otodectes, because cat use to shake and scratch on the exact area where the mites live which causes the mites being thrown away and stay on the other part of the body. Besides Otodectes, fungi and cat lice were also identified on the skin scraping examination. Fungi and lice infestation caused similar symptoms to mite infestation on cat skin. These two agents should be considered as the differential diagnoses to mange caused by mites on cat. Otodectes can be transmitted to human through direct contact so people awareness should be taken seriously about this zoonotic disease

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
