Judul: Bio-economic model of multispecies exploitation of pelagic fishery resources in bali strait
Abstrak: Tropical fishery resources in Indonesia comprised of diverse species resources, thus one type of fishing gear may yield more than one species of fish. Indonesian pelagic fishery resources feature rich potentials, with particular interest to Bali Strait, in where most of existing fishery resources were exploited using purse seine with double fishing lines. This type of fishing gear captured several species of fish, e.g. Lemuru (Sardinella spp.), Tongkol (Euthynnus spp.), Layang (Decapterus spp.), Kembung (Rastrelliger spp.), etc. Accordingly, this research aimed to: (1) analyze exploitation level multispecies pelagic fishery resources in Bali Strait; (2) analyze the optimal level of exploitation and sustainable fisheries for pelagic multispecies resources; and (3) to determine appropriate management policies. The analytical method used was bio-economic multispecies approach with reference to dependencies between different species in Bali Strait. The results showed present condition of exploitation of pelagic multispecies fishery in Bali Strait, and the actual production is lower compare to sustainable production. Current biological and economical thresholds were higher than current exploitation yield. Similar profile was noted for the actual production and fishing effort, which were below optimal value. Consequently, this study revealed that pelagic fishery resources management in the Bali Strait featured inadequate level of economic efficiency. The existing exploitation method for pelagic fishery resources in Bali Strait with purse seine using two fishing lines can be increased in order to obtain the maximum economic benefits, while still maintaining fisheries sustainability for multispecies resources. Maximum economic rents was obtained from cumulative economic rents of different pelagic fish species. Thus, multispecies approach should be the basis in determining the policy of pelagic fishery resources management in Indonesia.

Judul: The model of capture fisheries management in the area of Bali Strait
Abstrak: The fisheries activity was being prime mover (around 80%) of the fishermen and the society economic in the area of Bali Strait. However, it would be very much trivial if the potency was not well managed and unable to give the prosperity for the fishermen society. The research purposes were to determine the level of fishermen prosperity, to forecast the production of major catch of fishes, to determine the level of fisheries business feasibility, to formulate the management of the capacity building for strategy of fisheries resources, and to build the management model of the area that guarantees the sustainability of fisheries development. The method used consisted of the level of prosperity analysis, forecasting analysis, business feasibility analysis, strategy analysis by using AHP, and model analysis by using SEM. The results of analysis showed that the level of fishermen prosperity in the area of Bali Strait was ‘moderate’ (total score=25.80). The production of lemuru tended to increase within the last several years and at the year of 2010 was forecasted to decrease 44,899.13 tonnes. The production of tongkol tended to decrease, and at the year of 2010 was forecasted to reach 2,035.30 tonnes. The production of layang also tended to decrease, and at the year of 2010 was forecasted to reach 1,967.01 tonnes. As the dominant fisheries business, purse seine one boat system (OBS), purse seine two boat system (TBS), gill net and ‘payang’ were very feasible to be developed in the area indicatively the values, NPV>1, IRR>6.25, ROI>1, and B/C Ratio>1. The development managed by the spesific institution establised by local governments (RK=0.284) was the right strategy of capacity building in order to manage the fisheries resources in the area. This specific institution roled to organize the fisheries resources conservation programs, to regulate the exploitation of fisheries resources based on local governments policy (SKB), to supervise selling price and fishing gears operation periodically, to provide the information centre of job opportunity and the vocational centre, and to facilitate the local revenue planning of the sector of fisheries. The management model of the area developed could fit some criteria such as goodness of fit (Chi-square, signifance probability, RMSEA, GFI, AGFI, CMIN/DF, TLI, dan CFII). The results of analysis of the model showed that some concerned components for sustainability guarantee of fisheries development in the area required were local market performance, export market performance, product supply of processing industry to the market, biodiversity, prosperity of fishermen, work force absorption of capture fisheries business and industry, growth of capture fisheries business, income of processing industry and tax.

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.
