Judul: Optimization of ecological-economic functions in target fishes-based coral reef management (Case of Hogow Island and Putus-Putus Island, North Sulawesi)
Abstrak: This study provides a framework to optimize the ecological-economic roles of the coral reefs. In general, it was aimed at developing the management optimization design in order to raise the ecological and economic functions of the coral reefs which oriented in utilization sustainability of the coral reef resources in Hogow and Putus-Putus Islands. The specific objectives were (1) to determine the spawning ground, the nursery ground and the feeding ground in the coral reefs and evaluate the relationship between the occurrence of target fish and the coral reef building benthic organisms in space and time; (2) to optimize the ecological-economic roles in spawning ground, nursery ground, and feeding ground in the target fish-based coral reef management; (3) to evaluate the benefits of coral reef ecosystem to the economy, social and culture of adjacent communities. Based on the target fish distribution pattern data of 2002 to 2011, Hogow Island was determined as spawning ground, Putus-Putus Island (Station 1 and 2) as nursery ground and Putus-Putus Island (Station 4, 5 and 6) as feeding ground. The optimization of ecological and economic functions of the coral reefs was reached at the live coral cover of 66.82 ha, the target fish stock of 165 tons/yr, the target fish production of 66.36 tons/yr, and the fishing efforts of 200 trips/yr. The success of the sustainable coral reef management in Hogow Island and Putus-Putus Island could result from the community and government‟s participation, and therefore, the governmental policies should integrate the ecological, economic, social, institutional, and technological aspects.

Judul: Analisis Ekologi–Ekonomi Pengelolaan Perikanan Berbasis Ekosistem Terumbu Karang (Studi Kasus Perairan Pulau Liwutongkidi, Kabupaten Buton,
Abstrak: Coral reef one among the most productive and biologically diverse ecosystem on the earth. This thesis tries to explore ecological and economic value of coral reef at Liwutongkidi, Buton District. This study aims to identify: (1) Identified base substrate composition characteristic, fish community structure (2) To estimate coral reef ecosystem economical value and (3) To provide coral reef ecosystem management concept based on ecology-economic model on Liwutongkidi Islands marine conservation area. The percentage of live coral cover estimated around 13:01% - 72.50% on the island Siompu, Kadatua and Liwutongkidi, with the average 46.92% based on lifeform and can be classified as moderate category. Based on reef fish census was found that the major fish group was 3,899 individuals, indicator fish groups was 347 individuals, and the target fish group was 1625 individuals with a diversity between 2.71 - 4.72, which has mean they were all in medium till high category, the uniformity of reef fish between 0.69 - 0.92 which has mean a high category and stable communities. Economy Total (NET) from the direct benefits of coral fisheries resources utilization in coral Kapoa Village, Villages and Countryside Tongali, Waonu were respectively Rp. 11.579.106,17, Rp. 43.051.173,27 and Rp. 15.640.846,46 per month. System analysis and coral fisheries simulation result showed that the third scenario was more ideal in fish biomass simulation analysis on Liwutongkidi Islands conservation area and surrounds, there was a reciprocal relationship amongst catch efforts and fish biomass in a whole time.

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
