Judul: Eutrophication of Two Sand Pit lake in Cikahuripan Village Cianjur
Abstrak: Sandpit lake is an artificial water bodies with small size filled with water because it has penetrated the underground water channels. As a new water body it has the potential to be exploited but without proper management, the usability of this sandpit lake can be short due to eutrophication process. The aims of this research were to describe eutrophication level and to analysis the trophic status of two sandpit lake in Cikahuripan Village wich is Situ no 5 and Situ no 6. The methodology of this research is descriptive analysis with sampling in Mei and July 2010. TRIX calculation results show the trophic status of both sandpit lake has been eutrofik that indicates eutrophication processes take place very quickly. This is supported by the parameters of physics, chemistry and biology both sandpit lake that characterized by high nutrients and productivity as well as the lack of brightness. Although there were observed that sandpit lake is still relatively new waters, but based on trophic status indicates eutrophication process has been going very quickly as a result of anthropogenic activities

Judul: Kajian Ekologi Situ Citayam, Depok Jawa Barat dalam Upaya Pelestarian dan Peningkatan Fungsi Situ
Abstrak: Situ or lake is one of tl~ep otential wetland that could be developed by natural or man made.Natunl situ need more intensive treatment, in order tlle function and the potency of situ will not lost.This research is done by studying the ecological condition of Situ Citayam freshwater. The study focused on the general condition of freshwater. Water quality analyzed by physical, chemical, and biological parameter. The abundance and, diversity of plankton were analyzed by Shannon Wiener diversity index (H'). Nitrogen and phospoms ratio was counted to get the main limited factor of water organism growth, and double linier regression analysis to know the relation of physical, chemical, and biological parameter. Physical and chemical of water quality showed tllat the condition of freshwater has been polluted in middle range. It caused by domestically waste water and soil erotion which causing superficial in some region. The indicator of the middle polluted level Situ Citayam is guessed from the mesosaprobic organism which found out, it consists of Brachionus, Oscillatoria, ~Melosira. Scenedesn~ us, Pediastrunr, Vorticella, and Spirogym. All the matters supported by index diversity of Shannon Wier in range between 1,12 to 1,30. Nitrogen and pl~osporus ratio counted show that the main limited factor of water organism growth in the situ was phosporus. The result of double linier regression analysis described a very close relation between the physical. chemical, and the biological parameter as well.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
