Judul: Spatial modeling of land use change in relation to spatial planning in Sukabumi Regency
Abstrak: Sukabumi Regency population growth of 1,14% per year have implies a growing demand of land to be used as built up area and other urban activities. The increase in housing needs have resulted in land use change from productive agriculture into built up area. This study aims to: (1) analyze land use changes in the period 2000-2010, (2) analyze the factors that drive the land use changes, (3) predict the use of land in 2032 using spatial models of land use change, (4) formulate directives refinement for regional spatial planning (RTRW) Sukabumi Regency. 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 rice field that decreased by 15,8%, the land use that decreased too is oil 0,4%, forest 0,5%, and others 2,7%. On the other hand, the land use that extensively increase is built up area that rise to 23,9% and dry land that increased 3,4%. The main pattern in land use change is from rice field into dry land or built up area. CLUE-S prediction produced an accuracy of 91,25%. Alternatives of policy that selected based on the study for the refinement of regional spatial planning is : (1) environmental oriented policies can reduced 4,54% of the incompatibility between land use and regional spatial planning, (2) food security-oriented policies can reduced 4,64% of the incompatibility between land use and regional spatial planning, and (3) combining environmental oriented policies and food security-oriented policies can reduced 4,65% of the incompatibility between land use and regional spatial planning.

Abstrak: Change in landuse in a city that characterized by dynamic nature and growth is very reasonable. So that, review of land use change is important enough to do in urban area that has rapid changes where generally agricultural land was acquired to meet the needs of land for residential and industrial/service area. Therefore, the purposes of this study are : 1) To Analyze the level of regional development and land use in Sukabumi, 2) To analyze the factors that causes land use changes in Sukabumi City, 3) To analyze land use in Sukabumi City compared with the land capability and the plan of spatial pattern in the Spatial Planning, and 4) To provide strategic policy of direction on land use in Sukabumi City. The result showed that there is only one district that is included in the Hierarchy I region, that is Cikole district. The form of land use in 2002 was dominated by paddy fields (35.13 %), residential (25.24 %) and non-agricultural green space (21.57 %). In the 2007, the dominance of paddy fields and nonagricultural green space are reduced to 34.62 % and 21.09 % accompanied by the increasing of residential to 26.15 %. Based on the results on Hayashi Quantification Type II, the distance to the central government, the distance to arterial roads and the region in Hierarchy II had significantly higher opportunities compared to other explanatory variables to cause land use changes from moor, non-agricultural green space, and paddy fields became the city's infrastructure and residential. From the analysis of land capability, land capability class III is the most land capability class in Sukabumi city (97.8 %). So it can be concluded that the land use in Sukabumi City still approriate with the land capability because land capability class III has a lot of land use options. However, when compared with the plan of spatial pattern in the Spatial Planning Year 2011-2031, there is a significant trend of decreasing area of farmlands from 2.321,43 ha to 375.18 ha and non-agricultural green space from 1.056,37 ha to 485.15 Ha followed by the trend of increasing area of residential from 1.282,48 ha to 2.661,26 ha and city’s infrastructures from 199.15 ha to 1.320,13 ha by the end of year 2031. The priority of strategic policy of direction on land use in Sukabumi City based on SWOT analysis is to establish area zoning with a set of determining and changing criteria of the function of urban space on the implementing of Sukabumi City’s Spatial Planning.

Judul: Isolasi komponen hemotoksin bisa ular kobra (Naja naja sputatrix)
Abstrak: Elisa ular adalah racun yang diproduksi oleh kelenjar bisa dan digunakan ular untuk mempertahankan dinat mencari mangsa. Bisa ini merupakan campuran dari berbagai komponen. Enzim adalah kompoth utama selain air. Enzim pada bisa ular sangat beragam jenis dan fungsinya. Fosfolipase dan arginin ipadase adalah enzim yang sering terdapat dalam bisa ular dan telah digunakan pada penanganan penyak seperti trombosis Penttian ini bertujuan mengisolasi komponen dari bisa ular kobra dan mengujinya menggunakan sel darah merah sapi 4% untuk aktivitas hemolisis dan bekuan fibrin sapi untuk aktivitas fibrinolisis. Uji aktivitas dilakukan terhadap ekstrak kasar dan fraksi kolom bisa ular. Fraksi kolom diperoleh dari pemurutan ekstrak kasar menggunakan kromatografi filtrasi gel (Sephadex G-75) untuk memperoleh fraksa paksu dengan serapan tertinggi pada A. 280 nm. Ekstrak kasar dan fraksi kolom dengan serapan tertinggi dilakukan pengukuran kandungan protein, Fraksi aktif hasil uji aktivitas selanjutnya ditentukan berat molekulnya (BM) dengan elektroforesis SDS PAGE. Basaglar kobra merupakan cairan pekat berwarna kuning dengan kadar air 71.45%. Dari hasil uji aktivitas diperoleh bisa ular hanya memiliki aktivitas hemolisis sel darah merah sapi secara langsung. Aktivitas ini ditunjukkan oleh fraksi kolom nomor 15 dan 16 tetapi tidak dalam ekstrak kasar. Penurunan konsentrasi ekstrak kasar tidak mempengaruhi terhadap adanya aktivitas hemolisis. Hal ini diduga karena mungkin terdapat inhibitor dalam ekstrak kasar bisa. Inhibitor memiliki BM yang berbeda dengan enzim hemalisis sehingga dapat dipisahkan menggunakan filtrasi gel. Berdasarkan hasil elektroforesis diperolch enzim bemolisis terdapat dalam ekstrak kasar dan tersebar pada fraksi kolom nomor 15 dan 16 dengan BM sekitar 27300 Da
