Judul: Spatial Analysis of Land Use Change in Relation with The Use of Zoning Area at Gunung Halimun Salak National Park
Abstrak: Gunung Halimun Salak National Park (GHSNP) is the largest tropical rain forest ecosystem in Java. GHSNP ecosystems play an important role as watersheds protection, microclimate, wildlife conservation, research, environmental education, ecotourism and preservation of local culture. A variety of land use activities by communities that does not comply with the zoning plan of GHSNP will cause degradation of the forest ecosystem. However, its change should be monitored to control forest degradation. This study aims to: (1) analyze land use changes in the period 2000-2010, (2) analyze the factors that drive the land use changes from forest to Non-forest, (3) predict the use of land in 2026 using spatial models of land use change, (4) formulate directives refinement for land use planning GHSNP. Land use change modelling has been introduced to predict future pattern of change. CLUE-S was used to simulate land-use change based on the driving factors. The results of the analysis showed there is changes in land use in the 2000-2010 period. The most extensive land use decline is forest that decreased by 5,5%. On the other hand, the land use that extensively increase is field that rise 2,21%, rice field that rise to 1,46% and bush that increased 3,4%. The main pattern in land use change is from forest into mixed garden, field and bush. (2) According to the regression analysis, the factors that drive the land use changes from forest to Non-forest is density population. (3). Prediction result show forest landuse increased occurs in scenario 2 and 3. The landuse of a mix garden, field, paddy field and shrubs increased in the scenarios currrent conditions and scenario 1. CLUE-S model is simulated in this study has an accuracy of 88.53%. Alternatives of policy that selected based on the study for the refinement of landuse planning is forest restoration policy on core zones, jungle zones and rehabilitation zones, namely the restoration efforts of forest from mixed garden, fields, paddy field and shrubs. This policy can reduce 9.23% of the incompatibility between land use and zoning plan.

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: Infeksin virus rota pada anak babi
Abstrak: Virus Rota sudah lama diduga sebagai salah satu penyebab diare pada anak babi yang baru dilahirkan. Hal ini diperkuat dengan berhasilnya Mebus dan kawan-kawan mengidentifikasi virus Rota pada kejadian diare yang ter jadi pada anak sapi yang baru dilahirkan. Infeksi virus Rota merupakan hal yang serius, kejadian yang mewabah pernah dilaporkan di Amerika Serikat, Inggris, Kanada dan Australia. Sedangkan kejadian di Indonesia yang dihubungkan dengan infeksi virus Rota belum dilaporkan. Virus Rota termasuk keluarga Reo viridea. Sesuai dengan namanya, virus Rota menyerupai roda (Rota = Wheel), mengandung asam nukleat (nucleid acid) yang berupa asam nukleat ribo (ribo nucleid acid, RNA) dan berserabut ganda (double stranded), tidak mempunyai selubung (envelop atau peplos). Hewan rentan adalah hewan yang berumur sangat muda. Selain menyerang babi, dapat pula menyerang sapi, domba, rusa, anjing, kucing, tikus, kelinci, unggas dan manusia. ...
