Judul: Konsistensi Rencana Tata Ruang di Kawasan JABODETABEK
Abstrak: Oengan meningkatnya jumlah penduduk maka kebutuhan akan ruang pun akan semakin meningkat, sehingga mendorong berkembangnya penggunaan dan pemanfaatan ruang. Bentuk-bentuk kebutuhan akan ruang adalah kebutuhan untuk pemukiman, pertanian, industri dan pariwisata kemudian akan mendorong berkembangnya penggunaan dan pemanfataan ruang berskala besar di .Tabocletabek (Jakarta, Bogor, Tangerang, Bekasi, dan Oepok). Keadaan ini bisa menimbulkan ketidakkonsistenan pemanfaatan ruang bila pemanfaatannya tidak sesuai dengan arahan pemanfaatan ruang yang ada, inkonsistensi yang terjadi dapat menimbulkan berbagai dampak negatif terhadap lingkungan.

Judul: Analisis Inkonsistensi Penggunaan Lahan terhadap Rencana Tata Ruang Kawasan dan Kemampuan Lahan (Studi Kasus Jabodetabek)
Abstrak: Jabodetabek is the greatest metropolitan region and the most dynamic region in Indonesia where economic growth is accompanied by a hight rate of demand for housing and other urban facilities. Spatial planning in this region is characterized by inconsistencies that occur between land use/cover, spatial plan as well as land capability. Inconsistencies also occur due to RTR that a lack of attention to environmental carrying capacity, especially land capability. The purposes of this study are: (1) to analyze the land use Jabodetabek in 2010, (2) to evaluate the inconsistencies between land use in 2010 againts the allotment of land according to Jabodetabekpunjur Region Spatial Plan (RTR), President Decree no. 54 year 2008, (3) to evaluate incompatibility of land use in 2010 to land capability, and (4) to evaluate the incompatibility of the allotment of land according to Jabodetabekpunjur Region Spatial Plan (RTR) to land capability criterias. The method of this research is using a combination of overlayed maps in accordance with the parameters and analyzed descriptively. The result showed that there are 11 types of land use of Jabodetabek in 2010 with the largest land use is land use for rice irrigated of 169.156,5 Ha or 26,45%, then settlement area of 157.728,5 Ha or 24,66%. Area of land use that is inconsistent with land allotment of RTR Region of 65.286,0 Ha or 10,21%. The greatest inconsistency on land allotment is occurred in allotment for B-4/HP zone (allotment for B-4 zone that ascertained as fixed production forest sphere or confined production forest sphere according to law regulation), while the land use wich most inconsistent is grove/shrubs. Land use that is not compatible to land capability are 134.874,9 Ha (21,09%) with the greatest incompatibility of land capability are on the land class III and the land use with greatest incompatibility is settlement area. The land allotment of RTR Region that is not compatible to land capability are in wide of 145.657,5 Ha (22,77%). Land capability class with the highest of inconsistency rate are the land classes III and II, while the largest allotment of lands that is not compatible with land capability are occured on allotment for B-2 zone (moderate density settlement) and B-1 zone (hight density settlement).

Judul: Peptides Hydrolysate Derived from Collagen of Snakehead Murrel (Channa striata) Skin Demonstrate Anti-oxidant and Anti-cholesterol Activities.
Abstrak: Anti-cholesterol and anti-oxidant play crucial role to combat cardiovascular disease (CVD) related to formation of arterial plagues from oxidation of cholesterol. In the past decades, research on bioactive peptides demonstrating anti-cholesterol and anti-oxidant activities have been reported as the alternative drugs. In this study, acid soluble collagen was extracted from the skin of snakehead murrel and employed to induce production of collagenase by Bacillus licheniformis F11.4. The collagenases secreted were in turn purified through AKTA Purifier (ion exchange, DEAE column) and used to produce peptides hydrolysate. The purified enzymes were grouped in two distinct collagenase fractions, designated as fraction D and F. Peptides hydrolysate produced by the fraction D was found to demonstrate HMG-CoA inhibitor activity comparable to pravastatin and limited anti-oxidant activity. Meanwhile, peptides hydrolysate generated using the fraction F demonstrated anti-oxidant activity comparable to BHT (2mM), vitamin C (2mM) and vitamin E (2mM), but limited HMG-CoA activity. Combination of the fraction D and F resulted in substantial HMG-CoA inhibition and anti-oxidant activities.
