Abstrak: Alternative methods for jouvenile fish counting to replace the manual method are image processing method and mass measurement method. Image processing is one of the computer algorithms that can observe and analyze an object without direct contact with the object being observed. The image of jouvenile fish was taken by using a container attached to a holding frame with a digital camera on its top. The resulted image was processed with a Visual Basic program to determine the area of jouvenile fish. The jouvenile fish area was then used to determine the number of fish. Based on the image analysis on the jouvenile size of 7.8 cm, the average area obtained was of 871 pixels with the standard deviation of 112 pixels. The jouvenile mass was measured manually on each sample. The average mass of jouveniles was 2.17 g with a standard deviation of 0.66 and an average body length of 6.48 cm. The measurement results were then used for the simulation data with Microsoft Excel. The simulation was to calculate the probability of certain jouvenile mass occurrences. The accuracy of image processing was quite high, that is, the calculation error was 4% for image capturing 0 second after fish release, 3% for 5 second after release, 5% for 10 second after release and 10% for 15 seconds after release in the grade 3-4 cm. In the grade 5-7 cm the average error was 6% for image capturing 0 second after fish release, 4% for 5 second after release, 7% for 10 second after release and 14% for 15 second after release. The best accuracy was obtained when image was taken at an interval of 5 seconds. The error of mass measurement method as it is compared to manual counting was 3.5 %, while the simulation of mass measurement method error was 2.3%.

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.
