Judul: Struktur dan Sebaran Komunitas Bintang Laut (Asteroidea) di Perairan Pulau Sapudi, Kabupaten Sumenep, Madura
Abstrak: One of the marine life which has not been widely known for its benefits are sea stars (starfish). Research on sea stars have not been widely reported or investigated in Indonesia compared to other countries such as Australia and Japan. The purpose of this research is to know the community structure of sea star (Asteroidea) and to know the relation between sea star with its characteristic of habitat. This study was conducted in June that starts with a site survey on June 28, 2012. Primary data collection at the study site on June 30, 2012 to July 3, 2012. This research was conducted in the coastal Sapudi Island, Sumenep, Madura. Data were collected by the line transect method which lay down along 50 meters. At each transect lines were laid 1 x 1 meter transect plots. Data analysis using the calculation of density of seagrass, density, dominance and the pattern of sea stars spreading and the relation between sea star and habitat characteristic. There are 4 species of starfish that can be found in the Sapudi Island, such as Arcaster typicus, Culcita novaeguineae, Linckia laevigata, and Protoreaster nodosus. Linkia levigata is one of the starfish species that can be found in every station. Five species of seagrass as one of the starfish habitat can be found in Sapudi Island, such as Cymodocea rotundata, Enhalus acoroides, Halophila ovalis, Syringodium isoetifolium, and Thalassia hemprichii. Thalassia hemprichii is the most dominated species in Site 1, Site 3, and Site 4. In Site 1, there can be found two types of seagrass, they are Thalassia hemprichii and Syringodium isoetifolium. Based on Morisita index, spread of Asteroidea in Sapudi Island consist of two species of distribution, such as cluster for Protoreaster nodosus and Arcaster typicus and kindred Linckia laevigata and Culcita novaeguineae.

Judul: Taksonomi dan Habitat Pilihan Bintang Laut di Perairan Pulau Hari, Sulawesi Tenggara
Abstrak: Organisms prefer habitats which provide most of their requirement for growing and populating. In order to minimize competition, each population develops habitat sharing in many ways including diet preference and habit, and defense mechanism. This habitat sharing is demonstrated as area that is inhabited by individuals of the population. Research in habitat sharing of seastars has been conducted in August-December 2012. Seastar specimens were collected from and observed at Hari Island Waters (South East Sulawesi), applying road sampling and free handpicking technique. Geography position of each individu of seastar was remarked in GPS (Geographical Position System), and the characteristics of area where each individu of seastars was found, growth type and cover area of corals, species and cover area of seagrass, type of the substrate, was recorded. These position of seastars were then overlayed on habitat map to develop area inhabiting by each population of seastars. Results of research uncovered nine species of seastars that taxonomically confirmed: Linckia laevigata (Linnaeus, 1758) (Ophidiasteridae: Valvatida), Linckia multifora (Lamark, 1816) (Ophidiasteridae: Valvatida), Nardoa tuberculata Gray, 1840 (Ophidiasteridae: Valvatida), Nardoa novaecaledoniae (Perrier, 1875) (Ophidiasteridae: Valvatida), Fromia monilis (Perrier, 1869) (Goniasteridae: Valvatida), Culcita novaeguineae Műller & Troschel, 1842 (Oreasteridae: Valvatida), Choriaster granulatus Lütken, 1869 (Oreasteridae: Valvatida), Echinaster luzonicus Gray, 1840 (Echinasteridae: Spinulosida), Acanthaster planci (Linnaeus, 1758) (Acanthasteridae: Spinulosida). Corals grew well surrounding Hari Island, especially in the north side encircling a 2.9 ha lagoon. Between lagoon and the island, there were seagrass area (± 0.4 ha) and open sandy area. Most seastars inhabited this area, giving a distribution of west-east-direction belt. L. laevigata was found with the largest number of individuals (58 ind.), distributing widely. The habitat preference did not show specific. N. tuberculata prefered area with branching corals while C. novaeguineae tended to live in sandy area both among seagrass and corals. A. planci as coral feeders prefered tubulate Acropora eventhough some individuals found on massive coral and sandy bottom among corals. C. granulatus were found in a small area of sandy bottom among coral closed to reef slope. F. monilis and N. novaecaledoniae were only found 3 and 2 individuals, distantly each other, inhabiting close to reef slope. These two species have never been reported in large number. Habitat prefered by each population of seastars which showed in spatial distribution map, demonstrated a strategy in minimizing competition among populations. This strategy concerned with live requirement and adaptation potential (morphology and habits) of each seastar species.

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.
