Abstrak: Artificial reefs is an artificial habitat which is created to resemble the characteristics of natural reefs to improve the community of coral reefs that have been damaged in natural waters ecosystem. The effectiveness of artificial reefs made of coconut shell is observed during the period of March 2012 - May 2012 in the waters of Pramuka island, Kepulauan Seribu, Jakarta. The method used experimental method, where bubu tambun is used to capture the specimen that will be analyze for it’s level of gonad maturity. The observations is done with the visual census method with 2 areas i.e. 1 meter and 2 meter that would later be analyzed for it’s index of diversity (H’), index homogeneity (E) and the dominance index (C) at the artificial reefs site. The results showed that 10 family with 13 species are dominant to stay while in the natural coral reef consists of 8 family with 25 described species. The result of fishing capture, it consist of 10 family (Pomacentridae, Balistidae, Chaetodontidae, Holocent, Labridae, Scaridae, Siganidae, Xanthidae, Muraenidae). Gonado Stomato Index (GSI) of fishing capture are GSI I (46%); GSI II (28%); GSI III (22%) and GSI IV (4%). Artificial reefs with 1 meter areas has a range of diversity index between 1.68 -2.5; and the uniformity index ranged between 0,68-1.07 and dominance index 0.11-0.16. Artificial reefs with 2 meters areas has a range of diversity index between 1,79 – 2,15; range of uniformity index 0.59-0.90 and the index of the dominance of 0.09- 0.16.

Abstrak: Latest stage development of coral recruits community on concrete artificial reefs were observed for nine months (from October 2009 to July 2010) by visual census and underwater photography methods. Amounts of 10 units of concrete artificial reef deployed in Pramuka Island waters and Gosong Pramuka in 2001 were used as an objects in this research. As a comparation, the condition of coral coverage and reef fishes in natural reef were observed by line intercept transect, quadrate transect, visual census, and underwater photography methods. In order to measure coral coverage area we used ImageJ 1. 42q software. In March 2010, amounts 457 coral colonies from 21 genera and 216 coral colonies from 16 genera were found in Station 1 and Station 2 respectively. In July 2010, the percentage of coral coverage on concrete artificial reefs reaches 41.46±13.37% (mean±SD) in Station 1 and 20.38±6.08% (mean±SD) in Station 2, while the percentage of coral coverage on natural reefs were 23.14% and 40.43% in Station 1 and 2 respectively. The coral recruits coverage on concrete artificial reefs had a strong positive relationship with its fish abundance in Station 1 where coefficient of determination (R2) reached 0.71.

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.
