Judul: Model Dinamika Stok Karbon Berdasarkan Laju Perubahan Tutupan Hutan dan Lahan di Provinsi Jawa Tengah
Abstrak: The enhancement of carbon emission from deforestration and forest degradation has leaded to the increase of global climate change. Hence, this research was conducted to make a dynamic model of landuse and carbon stock and to estimate the carbon stock in Central Java. The change of carbon stock was being evaluated to identify its relation to forest change and landuse rate in Central Java using a system dynamic model. The result shows that there was a reduction of carbon stock caused by deforestation and forest degradation. The research also found that in 2004 the total carbon stock was 182.3 mega tons and in 2050 is predicted to decrease by 49.1 mega tons to 133.2 mega tons. The application of forest and land rehabilitation, law enforcement, evaluation of forest plantation management, and conservation province

Judul: Model Dinamika Simpanan Karbon Akibat Perubahan Kawasan Hutan di Provinsi Sumatera Barat
Abstrak: The rate activity of Forest landuse changed in the world was increase. It caused by a reduced ability from forest to absorb the carbon. Based from this fact was considered the need of a researched at a scope certain areas to known the reserved carbon available and known any factor influenced it. The point of this researched was to made a dynamics model and known the factor that effected a change of forest areas, measured the dynamics of carbon stock in the forest of West Sumatera Province and made an alternative scenario that could be positve impact on the mistress of carbon that was exist. Based on this research was known deposit of carbon stock decreased every year. There was a decline of 48.448.999,07 ton or decreased by 949.980,38 ton a year. From this researched was known forest carbon in Sumatera Barat was decreased caused of transmigration and mining activity. Scenario like extended HTI cycle, used 30 years cycle on HPH and restrictioned changed the region could provided positive effect on saved carbon that was exist.

Judul: Peran Imunoglobulin Y (IgY) sebagai Anti Adhesi dan opsonin untuk Pencegahan serangan Salmonella Enteritidis
Abstrak: Ayam petelur memiliki peranan penting sebagai penghasil antibodi poliklonal. Antibodi ayam atau dikenal dengan IgY dapat dipurifikasi dari kuning telur. Biaya untuk memproduksi IgY relatif lebih murah daripada antibodi mamalia karena biaya pemeliharaan ayam tidak mahal, relatif lebih murah dan cepat menghasilkan telur. Penelitian ini bertujuan untuk mempelajari cara memproduksi IgY anti S. Enteritidis dari telur dan mengetahui peran IgY S. Enteritidis sebagai anti adhesi dan opsonin untuk pencegahan serangan S. Enteritidis. IgY spesifik dikoleksi dari telur ayam Single Comb Brown Leghorn yang telah diimunisasi dengaan antigen untuk S. Enteritidis. Imunisasi diaplikasikan secara intravena dengan dosis antigen untuk S. Enteritidis 0.5 ml (109 sel/ml) selama tiga hari berturut-turut pada minggu pertama. Selanjutnya dilakukan pengulangan imunisasi sebanyak 3 kali dengan interval waktu seminggu secara intramuscular dengan dosis untuk antigen 1 ml (109 sel/ml) S. Enteritidis dalam Freund’s adjuvant complete di minggu kedua dan Freund’s adjuvant incomplete di minggu ketiga dan keempat. Uji agar gel prepitasi (AGP) dilakukan untuk mengetahui terbentuknya IgY anti S. Enteritidis. Ekstraksi IgY dari kuning telur menggunakan metode PEG-amonium sulfat, kemudian dipurifikasi dengan fast protein liquid chromatography. Konsentrasi IgY yang telah dimurnikan dihitung dengan spektrofotometer UV dan untuk mengetahui berat molekul dari IgY dilakukan dengan SDS-PAGE.
