Judul: Analysis of Mangrove Crab Habitat Suitability in Mundupesisir Village, Cirebon
Abstrak: Hutan mangrove merupakan habitat utama bagi Scylla serrata yang dimanfaatkan secara berlebihan menyebabkan penurunan jumlah populasi kepiting bakau. Maka dari itu, diperlukan kesesuaian habitat kepiting bakau untuk pemanfaatan perikannan yang berkelanjutan. Analisis kesesuaian habitat kepiting bakau dilakukan menggunakan pendekatan nilai indeks kualitas habitat (IKH) yang disusun berdasarkan hasil modifikasi Tahmid et al. 2015. Hubungan antara keberadaan kepiting bakau dengan kualitas habitat kepiting bakau dianalisa dengan analisis statistik multivariabel yang didasarkan pada Analisis Komponen Utama (Principal Component Analysis). Total luasan mangrove yang diperoleh dari pengolahan Citra Sentinel-2A sebesar 7 ha dengan kelas kerapatan tertinggi berada pada kelas rapat dengan luas 6,72 ha dan terendah berada pada kelas jarang dengan luas 0,014 ha. Berdasarkan hasil analisis, habitat kepiting bakau di kawasan mangrove Desa Mundupesisir, Kabupaten Cirebon berada pada kategori sesuai dengan luas 5,73 ha dan sangat sesuai dengan luas 1,27 ha. Hasil analisis PCA menjelaskan bahwa parameter salinitas dan kerapatan mangrove paling berpengaruh dengan keberadaan kepiting bakau., Mangrove forests are the main habitat for Scylla serrata which are often overused which causes a decline in the population of mangrove crabs. Therefore, it is necessary to suit mud crab habitat for sustainable use of fisheries. Analysis of mangrove crab habitat suitability was carried out using the habitat quality index (IKH) value approach which was prepared based on the modified results of Tahmid et al. 2015. The relationship between the presence of mud crabs and the quality of mud crab habitat was analyzed using multivariable statistical analysis based on Principal Component Analysis. The total area of mangroves obtained from processing Sentinel-2A imagery is 7 ha with the highest density class being in the dense class with an area of 6.72 ha and the lowest being in the sparse class with an area of 0.014 ha. Based on the results of the analysis, mangrove crab habitat in the mangrove area of Mundupesisir Village, Cirebon Regency is in the suitable category with an area of 5.73 ha and very suitable with an area of 1.27 ha. The results of the PCA analysis explain that the salinity and density parameters of mangroves have the most influence on the presence of mangrove crabs.

Judul: Karakteristik habitat dan potensi kepiting bakau (Scylla serrata, S.transquaberica, dan S.olivacea) di Hutan Mangrove Cibako, Sancang Kabupaten Garut Jawa Barat
Abstrak: The research was conducted in August - November 2011. The site contains six stations, each station in three zones. Station 1 and 2 was placed in zona A where zone A in the front area of mangrove forest. Station 3 and 4 was placed in zone B that location in the middle of mangrove forests. Station5 and 6 was placed in zone B where location in behind the mangrove forest. This study aims to obtain data and information on the habitat characteristics and potency of mud crab based on the existence of species, abundance, and size distribution. The method used was a survey. Observations of habitat characteristics performed in-situ by the method of sampling transect line plot. Cluster evaluation of habitat characteristic used cluster analysis. Analysis of habitat characteristics with potency of mud crab used correspondence analysis. The results showed that the parameters of habitat 1 and 2 had been similarity, and this was classified as groups of zone A. The similarity of parameters in station 3 and 4 were classified as group of Zone B, and the similarity of parameters in stations 5 and 6 were classified as group of zone C. S.serrata dominated in zona A where the substrat were mud with range of salinity between 24 – 30 ppt, totaled 73 ind. S.tanquaberica dominated in zone B where the substrat were mud with range of salinity between 22 – 25 ppt, totaled 94 ind. S.olivacea dominated in zone C where the substrat were clay with range of salinity between 18 – 23 ppt, totaled 45 ind. The abundance of mud crabs were in dark moon, where totaled zona A was 57 ind, zone B was 68 ind, and zone C was 32 ind. Mud crabs had possess of negative phototactic, because the habit of mud crab often refuge and hiding on a substrate that was not exposed to light directly. The high density of mangroves were found in zona A and B. which Third of mud crabs associated with mangrove that had density so higher. The average of litter weight as source of food for macrozoobentos, each which of was 200.72 g and 204.83 g. The average of macrozoobentos abundance, each which of was 13 ind/m2 dan 17 ind/m2 . Therefore, mud crabs would interest to settle in zone that had abundance of macrozoobentos as source of food.

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.
