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 dari Perubahan Tata Guna Lahan Kawasan Hutan di Sulawesi Selatan
Abstrak: Landuse change and forest degradation occur in many areas in Indonesia, including South Sulawesi that may affect carbon stock. Carbon stock decrease can be overcome by carbon mitigation. Carbon stock dynamic should be calculated to determine the amount of carbon in atmosphere that can be absorbed by forest. The objectives of this research were to estimate changes of forest cover and carbon stock in South Sulawesi and to build scenarios of carbon emission mitigation in South Sulawesi. The method used for building the model was system approach, which would explain the comparison of landuse change and its carbon sink rate in research location. The decrease rate of forest area was 7 362 ha/year. Carbon stock in 2006 was 539 mega ton C and fell by 15 mega ton C in 2050. There were four scenarios to mitigate carbon in this research: law enforcement, conservation province, tree planting on critical land, and forest reclamation after mining. The scenarios can prevent the rate of decreasing even increase carbon stock in South Sulawesi.

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.
