Abstrak: An increasing number of population caused land use/land cover change in Cibodas Biosphere Reserve. One of the approach to rapidly assess land use conversion is by using remote sensing technology. Therefore, the purposes of this study are : (1) to analyze land use/land cover change in 1999 and 2011 and the factor that affecting land use/land cover changes; (2) to identify people preference about land use/land cover change that can be tolerated; (3) predicting land use/land cover allocation approach with Cellular Automata (CA) and (4) to conduct controlling scenario land use/land cover changes in the Cibodas Biosphere Reserve that can support the sustainability of Mount Gede Pangrango National Park. The result showed the form of land use in 1999 was dominated by dry field and mixed farms, amounting to 44.25% and in 2011 the dominance of dry field and mixed farms was reduced to 38.16% accompanied with an increase in settlements from 16.19% to 20.41%. Based on AHP result, land use/land cover change is caused by population growth, source of income, slope, elevation and soil type. Land use/land cover change that can be tolerated by society is changing forests into dry field and mixed farms which have a value of 0.249 or 24.9%, and from dry field and mixed farms to residential with a value of 0.206 or 20.6%. Landuse prediction in 2023 show that dry field and mixed farm is 34,34 %, forest 30.97%, settlements 23.39%, fields 11.14%, edelweis 0.08%, grass / shrub 0.05% and 0.03% of water bodies. There is three scenarios to control land use/land cover change in Cibodas Biosphere Reserve.

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
