Judul: Kajian perkembangan larva dan pertumbuhan spat Tiram Mutiara Pinctada maxima (Jameson)pada kondisi lingkungan pemeliharaan berbeda
Abstrak: Major constrain in the pearl oyster breeding that are lowest of growth and development of larvae to spat and also low survival rate. One of the affected factors its unknown the optimum of rearing environment conditions, such as temperature, salinity, dissolved oxygen and light intensity. The objective of this research was to determine feeding activity, levels of food consumption, types and correct density of feed for optimizing of larvae growth and development of spat so that obtained high survival rate. This research consisted of four levels experiments, which are the study of larvae rearing in laboratory, spat rearing in laboratory, rearing of larvae and spat under optimum environment condition and study of spat rearing in the sea. Factorial completely randomized design was applied to know that effect of types and feed density, physiology response of larvae and spat to the levels of temperature and salinity. Completely randomized design was applied to the study of response of larvae and spat to the levels of light intensity. Randomized block design was applied to the study of spat in natural sea waters.

Judul: Development of Rainbow Fish Larvae at Different Rearing Temperatures
Abstrak: Perkembangan larva ikan mengalami suatu fase kritis pada masa endogenous feeding yaitu fase asupan makanan utama didapatkan dari kuning telur bawaan setelah menetas. Penelitian ini bertujuan mengevaluasi perkembangan telur dan larva ikan pelangi (I. werneri) pada suhu pemeliharaan yang berbeda (24 ºC, 28 ºC, 32 ºC). Pengamatan perkembangan telur meliputi waktu dan jumlah telur menetas yang diamati setiap 24 jam selama ±7 hari. Perkembangan larva yang diamati meliputi abnormalitas pada awal pemeliharaan saat setelah menetas, penyerapan kuning telur, ukuran bukaan mulut, tingkat kelangsungan hidup larva diamati setiap 12 jam selama 144 jam (±6 hari) sampai kuning telur habis. Suhu media inkubasi dan pemeliharaan yang berbeda memengaruhi jumlah telur yang menetas, kecepatan waktu penetasan, penyerapan kuning telur, bukaan mulut, sintasan larva, panjang total serta abnormalitas. Larva ikan pelangi menunjukkan laju penyerapan kuning telur yang cepat dengan tingkat kelangsungan hidup larva yang tertinggi sebesar 26% pada suhu media pemeliharaan 28 ºC., The development of fish larvae experiences a critical phase during the endogenous feeding period, namely the phase where the main food intake is obtained from the innate egg yolk after hatching. This study aims to evaluate the development of rainbow fish (I. werneri) eggs and larvae at different rearing temperatures (24 ºC, 28 ºC, 32 ºC). Observations of egg development include the time and number of eggs hatching which are observed every 24 hours for ± 7 days. Larval development observed included abnormalities at the start of rearing after hatching, egg yolk absorption, mouth opening size, larval survival rate were observed every 12 hours for 144 hours (±6 days) until the egg yolk ran out. Different incubation and rearing media temperatures affect the number of eggs that hatch, the speed of hatching, egg yolk absorption, mouth opening, larval survival, total length and abnormalities. Rainbow fish larvae showed a fast rate of egg yolk absorption with the highest larval survival rate of 26% at a rearing media temperature of 28 ºC.

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.
