Judul: Mangrove Vegetation Structure and Its Relation  to Environmental Characteristics of Coastal Waters of Tanjung Widoro Village,  Gresik, East Java
Abstrak: Perairan Tanjung Widoro memiliki keanekaragaman jenis mangrove yang cukup tinggi. Penelitian ini dilakukan untuk mengetahui kondisi mangrove di Perairan Tanjung Widoro. Pengumpulan data menggunakan metode purposive sampling melalui pengamatan langsung terhadap empat stasiun pengamatan mengenai kondisi vegetasi mangrove dan parameter perairan (suhu, salinitas, pH, oksigen terlarut, dan fraksi sedimen). Analisis data meliputi INP, RDi, RFi, dan RCi, serta Correspondence Analysis (CA) dan Principal Component Analysis (PCA). Pada lokasi pengamatan ditemukan sepuluh spesies mangrove, di antaranya Rhizophora mucronata, Avicennia alba, Sonneratia alba, Rhizophora stylosa, Avicennia officinalis, Rhizophora apiculata, Avicennia marina, Ceriops tagal, Bruguiera gymnorrhiza, dan Rhizophora mangle. Spesies R. mucronata dan A. alba dicirikan substrat berpasir yang selalu tergenang dan dipengaruhi pasang-surut, spesies A. officinalis dicirikan substrat pasir dan tumbuh di dekat muara sungai, spesies R. apiculata dan A. marina dicirikan substrat pasir kasar dengan salinitas yang cukup tinggi., Tanjung Widoro has a fairly high diversity of mangrove species. This research was conducted to determine the condition of the mangrove on Tanjung Widoro. Data collection used a purposive sampling method through of four stations regarding the condition of mangrove vegetation and water parameters (temperature, salinity, pH, dissolved oxygen, and sediment fraction). Data analysis included IVI, RDi, RFi, dan RCi, Correspondence Analysis, and Principal Component Analysis. At the site, ten species of mangrove were found, including Rhizophora mucronata, Avicennia alba, Sonneratia alba, Rhizophora stylosa, Avicennia officinalis, Rhizophora apiculata, Avicennia marina, Ceriops tagal, Bruguiera gymnorrhiza, and Rhizophora mangle. Mangrove R. mucronata and A. alba can grow on sandy substrate that are always flooded and influenced by tides, while A. officinalis on sand substrate and grow near river, R. apiculata and A. marina on coarse sand substrate with fairly high salinity.

Judul: Hubungan Sifat Tanah dan Tipe Vegetasi Mangrove di Desa Blanakan, Kabupaten Subang.
Abstrak: Mangrove ecosystem is a typical marine tropics and subtropics with a very important role for the balance of nature. However, currently the target of exploitation of mangrove forests due to the demands of development which focuses on economic interests. More than a half of the mangrove forest area in Indonesia in a bad damaged state, around the North Coast of Java, has long been eroded by the needs of its population to the land. Mangrove forests that relatively in good condition on the north coast of Java is in the village Blanakan, so the mangroves in the area need to be in the preserve. This study aims to determine the nature and characteristics of soil that affect the growth of mangrove land the village and to know the relationship of the soil properties with different types of mangrove vegetation that grows in the village Blanakan. There are 4 zones studied based on the type of vegetation growing in these locations. Zone 1 (BSR1) with vegetation Avicennia marina, zone 2 (BSR2) with Rhizophora mucronata vegetation, zone 3 (BSR3) with vegetation Jeruju, and zone 4 (BSR4) with vegetation Sonneratia acida. The sample of soil that have been researched are morphological and chemical properties. All of soil conditions are not significantly different by morphology. Those all zones are type Hydraquent soil. Chemical properties which have an influence on mangrove vegetation difference are the Electrical Conductivity (DHL/EC), water content at field condition, percentage saturation of the cations, the percentage of ESP, and SAR values, and value of soil. The DHL/EC, the percentage of ESP, and SAR values show the influence of sea water. Zone 1 had the soil more ripe than zone 2, 3, and 4. Cation saturation of each zone has its own characteristics. A base saturation zone was dominated by sodium saturation and followed by increasing the depth of soil. Zone 1 showed many salt-free and the salt free content increased from the upper to the lower layer. Base saturation in zone 2, between the top layer of soil is different from the middle layer and bottom layer. The top layer of soil in zone 2 was dominated by the saturation of magnesium, but in the middle layer and bottom layer was dominated by sodium saturation. Sodium saturation in zone 2 further decreased, this suggest that salt-free in this zone was diminishing compared to zone 1. In zone 3 and zone 4, there are no free salts and base saturation was dominated by magnesium, and also increased of addition calcium.

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.
