Judul: Sustainable Development Pattern of Scad Resources (Decapterus spp) in North Maluku Waters
Abstrak: The potential of scad resources in North Maluku waters is expected to be abundant with the utilization level considered as developing, however, specifically there is different fishing stress on scad resources. The objectives of the research are: 1) to determine the main priority for scad fishing technology based on biological, technical, social, economic, and environmentally friendly aspects; 2) to determine the optimization of scad fishery management; 3) to determine biological characteristics of scad (Decapterus macarelluas) based on fish population parameter approach; 4) to determine minimum net mesh size of the selected fishing gear; 5) to determine the pattern of fishing season and the impact on catch of scad; and 6) to arrange the sustainable development pattern of scad resources in North Maluku waters. The research used survey and observation method. The method applied in the analysis was scoring and value function, Gordon-Schaefer model on sustainable production function and bio-economy, Linear Goal Programming model, fish population parameter analysis, simple linear regression analysis, moving average method, and descriptive model. Result showed that scad fishing technology that is appropriate to be developed is mini purse seine. Estimation of scad catch result optimum value is 19.754, 248 ton per year with optimum catch effort is 28.135 mini purse seine standard trip, and thus the maximum profit obtained is Rp. 90.717.199.850,00. The allocation of recommended mini purse seine fishing unit is 202 units that employ around 2626 fishermen. The analysis of several scad (Decapterus macerellus) population parameters resulted faster growth of female scad compare to the male and both reached maximum length in the age of 4 years. Scad growth characteristic is “Alometric minor”, which means that the growth of its body length is faster than its weight. Scad caught was dominated by immature gonad. The highest amount of mature gonad scad was found in March and the size at first gonad maturity is reached at 25,8 cm total length. The spawning period is during April/May. Fecundity obtained is around 28875-84000 with the total length vary from 268- 310 mm. The amount of egg is highly influenced by the fish’s total length. The pattern of fishing season is following the scad’s abundance pattern. The peaks of scad fishing season occurs in March-October with the highest point reached in August. While fishing ground December – February indicated by lowest catch. Catch area and scad fishing season in various waters in North Maluku covers: (1) the center part of North Maluku, with fishing season from February -May and July - September; (2) southern part of North Maluku with fishing season from April - October; and (3) northern part of North Maluku with fishing season from April - September. A sustainable development pattern of scad resources in North Maluku waters has been arranged, which covers 5 components: Selected scad fishing technology, optimization of scad fishery management, scad biology, minimum mesh size of chosen fishing gear, and the pattern of fishing season.

Judul: Analysis of mini purse seine Fishery Development based on Opt imization of Small Pelagic Resources In North Maluku Province
Abstrak: The small pelagic in North Maluku is highly potential, but the utilization has been not optimum due to low productivity of mini purse seine fishery. The objectives of the research are: 1) to determine relationship between production factors and mini purse seine fishing unit production; 2) to determine optimum mini purse seine fishing unit for maximum production and economic profit level in the utilization of small pelagic resources; and 3) to determine feasibility of mini purse seine fishery in North Maluku. Survey and observation methods were used in this research. Multiple regression analysis to analyze relationship between production factors with catch of fishing unit mini purse seine, production surplus method used on fish resources stock estimation, Gordon Schaefer model to analyze fishing bio-economic condition and financial analysis to analyze business revenue and feasibility. The result from multiple regression analysis showed the technical production factors that have significant effect to the fish production are number of labor, number of fishing days, mini purse seine height and mini purse seine length, otherwise factors that have not significant effect is boat size. The result from bio-economic analysis showed that exertion level of small pelagic resources using mini purse seine is almost optimum (MEY). The optimum catch for small pelagic is 20.781,87 tons per year with the optimum effort of 36.975 trips per year or equivalent with 205 mini purse seine units. Business and financial analysis of small pelagic fishing using mini purse seine showed BEP for production value per year of Rp 68.837.032,- and production volume per year of 28,89 tons. Value of NPV is Rp 453.157.157,- with IRR value of 47.23% and Net B/C value of 2.19 (more than 1), therefore mini purse seine in North Maluku is feasible to be developed.

Judul: Telaah Histopatologi Urolithiasis Pada Kucing
Abstrak: Urolithiasis adalah suatu keadaan dimana ditemukannya batu di dalam saluran urinaria. Batu tersebut dibentuk dalam pelvis ginjal dan bergerak turun sepanjang ureter kemudian masuk ke dalam vesika urinaria dan uretra. Penulisan ini bertujuan untuk mempelajari lebih dalam secara histopatologi tentang kasus kematian seekor kucing dengan urolithiasis yang dinekropsi di Laboratorium Patologi FKH-IPB. Pemeriksaan patologi anatomi menemukan adanya fokal atelektasis paru, dilatasi ventrikel kiri jantung, hidrothoraks, hidroasites, ginjal pueat dan batu-batu berbagai ukuran dengan diameter 0,1-0,5 em pada vesika urinaria yang berdarah. Pada pengamatan histopatologi menunjukkan pembendungan semua organ, nephritis interstitialis kronis disertai bentukan mikrokista dan endapan mineral pada lumen tubuli dan sistitis nekrotik disertai pendarahan yang meluas. Pemeriksaan pada organ paru-paru ditemukan lumen alveolus sebagian mengempis dan sebagian lagi meluas. Dinding alveol menebal akibat adanya akumulasi eritrosit. Sedikit koloni bakteri tampak dalam lumen usus, bercampur dengan epitel usus yang terlepas di ujung viii. Hati mengalami pembendungan, ruangan sinusoid tampak meluas. Beberapa megakariosit tampak di dalam pulpa merah yang menunjukkan adanya aktivitas hematopoetis. Organ jantung tidak menunjukkan adanya perubahan histopatologi yang spesifik.
