Judul: Dynamic Model of Small Scale Timber Regulation and Carbon (Case Study at Indegenous Forests in Manokwari District West Papua Province).
Abstrak: This study aims to construct a scenario timber regulation and carbon sequestration in the logged indigenous forests in Manokwari West Papua Province. The method used in this research is descriptive method with survey method and the method of analysis of documents. The results showed that the structure of the logged forest stands Customary logging can still be done, both now and in the next cycle. Cutting cycle of 20 years in the logging scenarios provide a greater Net Present Value (NPV) at different harvest intensities compared with the other cutting cycle. The intensity of logging negatively correlated with stocks of carbon in the stands and the amount of emissions resulting from logging. The intensity of logging 0% will give the maximum NPV on the scenario of environmental services for the absorption of CO2 emissions. Logging scenarios and scenarios of environmental services for the absorption of CO2 emissions can be run simultaneously on the intensity of cutting a maximum of 25% assuming that emissions resulting from logging only 50% of the total harvest. Logging scenarios and scenarios of environmental services for the absorption of CO2 emissions on emission levels 75% and 100% can not be performed simultaneously. The volume of felling and felling intensity negatively correlated with the stock of carbon in the stands. NPV of logging negatively correlated with NPV value of environmental services for the absorption of CO2 emissions. Negafit harvest intensity correlates with the amount of CO2 emissions resulting from logging.

Judul: Model Simulasi Pengelolaan Hutan Berbasis Karbon (Studi Kasus di IUPHHK PT. Mamberamo Alasmandiri, Kabupaten Mamberamo Raya, Provinsi Papua)
Abstrak: In order to fullfilling market demand of wood which still increasing and to support government commitment on global emission reduction effort, there should be a simulation to determine good formula on forest management. This formula applied when forest moratorium occur in Indonesia. The study simulating some forest management scenario’s by considering another benefits of forest wood, because wood, carbon and non timber forest products has a high market demand nowadays. The scenario’s include forest management with TPTI system, carbon based forest management system, combination system between carbon based and ants nest scenario, carbon based and mace oil combination management scenario, and carbon based and sago utilization management scenario. A proper forest management could give a good economic, ecology and social benefit. The scenario of simulation results a value of business feasibility on each scenarios, has a positive value of net present value (NPV), benefit cost ratio (BCR) more than 1 and internal rate of return more than interest rate used. This means each scenario of business is feasible. The highest value of NPV, BCR and IRR is on carbon combination forest management and sagoo utilization, by value NPV of Rp. 25.170.588,59. This value indicates the cost used on forest management giving benefit during financial analysis time, which is 5 based on present value. BCR value of carbon based and sago utilization scenario is 1.47 This condition illustrates benefit obtained as much as BCR during project time, is bigger than the cost issued. Meanwhile the IRR value of carbon based and sago utilization scenario is 28% above bank rate is 10%, this value indicates the good criteria of business feasibility based on financial is combination carbon based and sago utilization forest management. This is also supported by a good level of sustainability of standing stock on next harvest cycle, due to banned wood utilization and turn to carbon sequestration service utilization.

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
