Judul: Pengaruh peubah sosial ekonomi terhadap perubahan penggunaan dan penutupan Lahan di Taman Nasional Gunung Halimun Salak
Abstrak: Gunung Halimun Salak is one of national park in Indonesia, located in West Java and Banten Province. In 2003, government has expanded its area by more than 70000 hectares. It caused a lot of conflicts between local communities and national park officials. Many case studies showed that the local communities has used the natural resources for construction materials, fuel wood, medicine, food, cultural needs, forages, hunting, handicraft, gold mining, agriculture land, and settlement. There was clear evidence that in Gunung Halimun Salak National Park, during 15 years period (1989-2004), forest cover area decreased by more than 25%. The objectives of the research are: 1) to identify socio-economic variables causing landuse and landcover change; 2) to estimate influence of key socio-economic variables; 3) to estimate the need of agricultural land and settlement for local communities; and 4) to estimate the direct benefit value of the national park. Selection of sampling location was used by stratified cluster sampling. Socio-economic data collected from interviews with 900 head of households which lived in 30 villages in and around the national park. The technique of data processing analysis were done using spatial analysis, descriptive analysis, linear regression analysis, population pressure analysis, and substitution and market price analysis. The result of analysis showed that the population growth, population density, land ownership, agricultural land and settlement expansion are the key variables that influenced landuse and landcover change. The need of agricultural land was 0.54 hectares per person, and the direct benefit value of the national park was more than IDR 237 billion per year.

Judul: Analisis Perubahan Penutupan dan Pola Pemanfaatan Lahan di Taman Nasional Gunung Halimun Salak Menggunakan Sistem Informasi Geografi (SIG) (Studi Kasus: Kampung Adat Lebak Picung)
Abstrak: Gunung Halimun Salak National Park (GHSNP) is one of the conservation areas that have been facing forest cover changes rapidly. It’s related to people activities in and around the area. One of the communities which have been living at surround the GHSNP is indigenous peopleof Kampung Lebak Picung, Desa Hegarmanah, Kecamatan Cibeber, Kabupaten Lebak, Banten. They have been practicing shifting cultivation system. It is feared the system willm lead to forest conversion in GHSNP area. Data and information of the conditions in Kampung Lebak Picung area can be analyzed through technology Geographic Information System (GIS). The aim of this research is to study land cover changes in Kampung Lebak Picung, to investigate factors that influence land cover change, and review procedures of land management by the community at Kampung Lebak Picung Social data, and ground control point were taken in Kampung Lebak Picung for one month in June 2009. Collected data included spatial data in the form of maps, Landsat image TM and ETM + in 1989, 1997, 2007 and attribute data include sociocultural conditions, management and land use, and people perception. Spatial data were prossed by using Geographic Information System technology and Remote Sensing. The result of image processing were analyzed qualitatively using the attribute data to determine its impact on land cover changes. Land cover types in Kampung Lebak Picung consist of forest, mixed gardens, shrubs, fields, rice fields, water bodies, open land, built up land, and no data. In the period 1989-2007, rice fields land cover type were decrease. Meanwhile fields and water body land cover type were increase. In general, several types of land cover area fluctuated. Fluctuations occur on forest land cover, mixed gardens, shrubs, and open land types. In 1997, forest area were increase 20,47 ha but mixed garden and shrubs decrease of 41.93 ha and 3.27 ha. In 2007, forest land cover types decreased of 19.28 hectares but shrubs were increase 2,50 ha. Land cover changes were influenced by the increasing population and implementation of shifting cultivation system to arable land use (mixed garden and fields). Most of income source is farmers (91.67%) therefore usage of arable land (paddy fields, fields, and mix gardens) was very high. It’s feared, it will lead to forest conversion to arable land. In fact for this period of reseaerch arable land is sufficient to meet the needs of the community. Generally, people had high perception for the existence of forest, but people's knowledge of the forests and national parks are still quite low. Factor that influence land cover change are social condition, especially in land management systems. To anticipate expansion of cultivation land into forest area, the National park should alocate those activities in spesific area/zone.For that purpose the National Park should supervise the activities.

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
