Judul: Variasi Kandungan C-organik pada Jenis Lamun yang berbeda berdasarkan Karakteristik Lingkungan di Pulau Panjang Perairan Teluk Banten
Abstrak: Seagrass is a type of plant that lives in coastal waters and has the potential to absorb carbon and also can be used as an indicator of water quality. Organic carbon is an important element needed by seagrass. However, climate change and industrial activities around the Banten Bay waters were contributed to the changes of its characteristic. With the ability of seagrass to absorb carbon, the increase in carbon emissions in the coastal waters can be potentially reduced. This study aimed to analyze the C-organic content of Seagrass above the substrate (leaves) and the bottom of the substrate (roots and rhizomes) which grew in different locations on Panjang Island. The sampling location was divided into 2 stations with a considering difference of environmental characteristic. While Seagrass organic is divided into two parts, the leaf part or above ground (Abg) and the root part or below ground (Blg). The data obtained was analyzed using correspondence analysis (CA). The results show a variety of organic carbon were found in leaves, rhizomes, and seagrass roots of Enhalus acoroides, Cymodocea rotundata, and Sryngodium isoetifolium. The results of the correspondence analysis (CA) between organic carbon in seagrass and organic carbon in the substrate indicate spatial distribution. C-organic content in the seagrass is influenced by the density and C-organic in the substrate is influenced by the substrate composition and environmental conditions.

Abstrak: Seagrass beds is one of ecosystem in coastal waters which is known for its high organic productivity. The productivity derives from litter fall, epiphyte, phytoplankton and suspended particles which trapped among seagrass. Organic material then undergoing a process of decomposition and becomes a source of nutrients. Furthermore, the nutrients will be used by seagrass itself and other aquatic organisms. Macrozoobenthos is a part of the organisms that served as a connector in material cycles and energy flow, from high-level producers to consumers in the waters. The presence of macrozoobenthos in seagrass bed, will enable to support higher fish production in coastal areas. From this starting point, these studies were conducted to analyze the connection between seagrass beds as a producer and organic matter traps and its influenced to macrozoobenthos community structure. The aim of this study is to know the effect of seagrass density toward the total organic material on the bottom substrate, to investigate the effect of seagrass density on the abundance of macrozoobenthos and to determine the influence of total organic material against macrozoobenthos abundance, as well as the rate of deposition of suspended particles (mg/cm2/day). Sampling were taken in the southeast and northeast part of Barrang Lompo Island. Result of the present study, showed that all of 2 stations in Barang Lompo Islands were dominated by 5 species of seagrasses such as Cymodocea serullata, Syringodium isoetifolium, Halophila minor, Halodule uninervis, and Thalassia hemprichii. About 70 genera of macrozoobenthos have been found in all observed stations comprised of 53 families, 7 classes, and 4 phyla. Macrozoobenthos diversity index relatively higher in seagrass beds compared to bare area. However, homogenity index in seagrass beds as well as bare area was high and was relatively homogen. Thalassia hemprichii, Cymodocea serullata and Syringodium isoetifolium are the main species in this area with high densitiy. Results of Principal Component Analysis (PCA) showed that seagrass with higher density were able to trap amount of total organic material in the substrate. Macrozoobenthos density were directly proportional with seagrass density and total organic material. Gastropods are commonly found in seagrass bed with higher density and higher total organic material. In contrast with the results mention above, bivalve are more common in bare area. Coastal waters with higher clay sediment concentration may able to trap higher suspended particles than those within sandy and silty sediment.

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.
