Judul: Sustainable Purse Seine Fishery Development Model in Pirigi Moutong District, Tomini Bay.
Abstrak: The deveIopment of purse seine fishety represent one of the alternatives h c h can be conducted as an effort to increase fishery product. Various aspects must be considered in the development of purse seine fishery, such as biological, technological, social and economical aspects (Biotecnosocionomic) representing basic course of studv and compilation mdel of the development of sustainable purse seine fishery (SISBANGPUR). The model expected to be one of the elernentan, concept of catch fishery management at Tomini bay. In model compilation of SISBANGPUR, data and information from each system performer and other stakeholder was collected observation and survey method through interviewed with questionnaires. The number of purse seine fishery as a research object are ten unit with 12.75 GT to 17.96 GT of weight, nine owner choosen by sensus sampling and 40 fisherman was chmsen by purposive sampiing. Data analysis consisting of calculation of everlasting potency and optimum effort using Surplus Prduction method: optimation technique by LP method; financial analysis of fishing effort by NPV, net B/C and IRR methods; policy analysis of development using AHP method and compilation of model using system modelling method. The fishing effort performance at P a r i ~M outong District, Tomini Bay obtained through simulation used LINDO software with scenario that estimated in the year of 2003, representing estimated the possibilip of fishing effort growth for one year forwards based on the development of the year 2002. Assumed that 100% of both types of strive to be transferred to become purse seine effort which justify with LP Winston method, hence based on the optimation analysis result, the addition of purse seine strive arrest can be optimize to the amount of 78 units with optimal advantage equal to Rp. 9.002.750.000. Validation test of SISBAXGPUR model showed that the value of absolute mean error (AME) equal to P= 0.057, absolute variation error (.AVE) equal to P = 0.073, the value of Utheil Coefficient equal to P = 0.044 having a meaning that there is no differences between simulation and actual value. Durbin Watson result test (DW-TEST) equal to 1 -96 indicating that deviation pattern bv fluctuatively less sharply, while value of Kalman Filter (KF) equal to 0.497 (KF4.50) indicate that uniformity between simulation to the actual was a little below the actual. The dynamic of model performance before and after examination of sensitivity model by using trend function showed periodically improvement follow the asymphtotic pattern during 25 year. This phenomenon indicated that functional intervention bv using trend function was effective enough and adaptive, this is showed from reference value before and after examination were relatively the same.

Judul: Study of Purse Seine Fishery and its Sustainability Status in Manado City Region Using Systemic Feedback Modeling
Abstrak: Keberlanjutan perikanan merupakan aktivitas pengelolaan dan pemanfaatan sumber daya ikan yang menjamin pemenuhan kebutuhan secara terns menerus. Sementara perkembangan hasil tangkapan ditentukan oleh umpan balik sistemis antara unsur sumber daya ikan dan unsur upaya tangkap yang dioperasikan. Dalam penelitian ini, status keberlanjutan perikanan pukat cincin di daerah Kota Manado ditelaah melalui dimensi-dimensi ekologi, ekonomi, sosial, teknologi, dan etika dengan menerapkan teknik RAPFISH. Di samping itu, perkembangan hasil tangkapan dari perikanan ini dianalisis melalui model umpan balik sistemis. Ordinasi status keberlanjutan perikanan pukat cincin temyata bervariasi nilainya menurut dimensinya, di antara 32.9 dan 78.8. Secara rata-rata semua dimensi, posisi perikanan ini ditunjukkan berada 53% dari status keberlanjutan yang tergolong baik. Pengembangannya berpeluang dilakukan melalui perbaikan k:ualitas atribut-atribut keberlanjutan perikanan seperti: upah rata-rata dan proporsi pekerjaan (ekonomi), sosialisasi penangkapan dan partisipasi keluarga (sosial), selektivitas alat tangkap dan kemampuan menangkap (teknologi), pilihan perikanan dan ketepatan pengelolaan (etika). Melalui penerapan upaya tangkap optimum, perilaku model yang semula berfluktuasi akan selanjutnya meningkat mulus menuju ke jumlah yang relatif konstan. Uji sensitivitas model menunjukkan peubah model berupa efisiensi panen, kapasitas stok, dan status keberlanjutan perikanan yang ditingkatkan secara tunggal dan/atau kombinasi, berpeluang menambah hasil tangkapan sekaligus nilainya. Dengan demikian, kebijakan umum yang dapat dipertimbangkan untuk pengembangan perikanan ini mencakup: peningkatan efisiensi panen, peningkatan kapasitas stok, dan perbaikan status keberlanjutan. Selain itu, standardisasi atribut-atribut keberlanjutan perikanan menurut alat tangkap dan sosialisasinya bagi semua pihak, disarankan untuk dilakukan, Fisheries sustainability is management and the utilization of fish resources which can guarantee the availability of that resources continuously. Meanwhile, the progress of catch is determined by systemic feedback between fish resources components and fishing effort components. In this research, the sustainability status of purse seine fishery in Manado was examined through ecological, economic, sociological, technological, and ethical approaches by employing RAPFISH technique. Moreover, the performance of the catch of this fishery was analyzed using systemic feedback model. The status of the purse seine fishery in this region was 53% of the fisheries sustainability which is classified as good fisheries. Improvement of this status can be done by improving several attributes qualities, among others: wage and sector employment (economy); socialization of fishing and kin participation (social); selective gear and catching power (technology); alternatives and just management (ethics). Through the application of optimal fishing effort, the behavior model that previously shown fluctuated in catch, was then increased to a relatively constant number. From sensitivity analysis, it was found that variable model such as harvest efficiency, stock capacity, and sustainability status which had been increased by itself and/or in combination, has the possibility to improve the catch and its value. By looking at those, the most possible thing to do to improve the fishery is through increasing the efficiency of harvest, stock capacity, and also the improvement of sustainability status. Beside that, standardization of fisheries sustainability attributes according to fishing gears which then followed by socialization of their use to the community, is also suggested.

Judul: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
