Judul: Model Dinamika Simpanan Karbon Kawasan Hutan di Provinsi K Kalimantan Barat
Abstrak: The issue of global warming is growing, that putting forests as one of solutions to decrease the concentration of greenhouse gases (GHGs) in the atmosphere. This study describes the tendency of the usage and utilization of forest areas on west Kalimantan province and its relationship to the stock of carbon in forest areas by using system dynamic method. The simulation of model until 2011 shows the occurrence of deforestation that causes loss of stock carbon 0f 62,74 megatons. The simulation of model up to 2050 on Business as Usual (BAU) will cause carbon stock losses amounted to 162,82 mega tons due to land conversion activities. The rate of forest degradation trough the year 2011 has resulted in carbon stock losses about 300 megatons or equivalent to 27,28 megatons/year. The simulation up to 2011 showed the value of plantation forest carbon stock reach 42,96 megatons. This number will continue to increase until it reaches 84,23 megatons by 2050. The application of Reduced Impact Logging (RIL) scenario, forest plantation harvesting cycle, and provincial conservation policy practice can reduce loss of carbon stock rate.

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: Perbandingan Histopatologi Ovarium Ayam sentul seleksi Yang Memiliki Titer Immunoglobulin Y Tinggi Dan Rendah
Abstrak: Telur ayam merupakan jenis makanan bergizi yang sangat populer di kalangan masyarakat yang bermanfaat sebagai sumber protein hewani. Permintaan telur dipengaruhi oleh beberapa faktor dalam industri peternakan. Immunoglobulin Y yang tinggi di ayam menghasilkan produksi telur yang banyak. Oleh itu, penelitian dilaksanakan untuk mengetahui perbandingan jumlah folikel pada ovarium ayam sentul seleksi yang mempunyai titer Ig Y tinggi dan rendah. Pada minggu ke-24, masing-masing 3 ekor dari titer Ig Y tinggi dan Ig Y rendah dimatikan kemudian dilakukan nekropsi dan dilakukan pengambilan ovarium untuk dilihat gambaran histopatologi. Hasil penelitian adalah, tidak ada perbedaan jumlah rataan folikel pada ovarium ayam sentul seleksi dengan titer Ig Y tinggi dibandingkan dengan ayam titer Ig Y rendah.
