Judul: Analysis of indonesian wood-based products trade and its impact on potential deforestation in several regions
Abstrak: Rendahnya posisi tawar produk berbasis kayu Indonesia di pasar internasional cenderung mendorong te~adinya penebangan hutan secara berlebihan. Tujuan ulama studi ini adalah menganalisis dampak perdagangan produk berbasis kayu Indonesia terhadap deforestasi potensial di beberapa wilayah, suatu isu krusial bagi Indonesia memasuki perdagangan bebas pada tahun 2012. Analisis merlggunakan model sistem persamaan simultan penawaran dan permintaan sektor pembalakan kayu bulat, industri kayu gergajian, kayu lapis dan pulp di wilayah Sumatera, Kalimantan, Sulawesi dan Maluku-Papua, yang kemudian diagregasikan menjadi total Indonesia, dan dikaitkan secara rekursif dengan proses deforestasi potensial.

Judul: The impact of trade policy on export performance of the indonesian primary wood products industry
Abstrak: Tujuan penelitian adalah untuk (1) mengindentifikasi faktor-faktor yang mempengaruhi kinerja ekspor , (2) mengevaluasi dampak kebijakan perdagangan kayu bulat terhadap kinerja ekspor periode tahun 1980-2002, dan (3) meramalkan dampak kebijakan perdagangan kayu bulat terhadap kinerja ekspor produk industri pengolahan kayu primer periode tahun 2007-2010. Alternatif kebijakan disimulasi dengan menggunakan model ekonometrika dalam bentuk persamaan simultan yang terdiri dari 25 persamaan struktural, 3 persamaan teknis produksi dan 11 persamaan identitas. Metode Two Stage Least Squares (2SLS) digunakan untuk menduga parameter persamaan struktural. Penelitian menganalisis 12 skenario peramalan yang terdiri dari 8 skenario dengan instrumen tunggal dan 4 skenario dengan kombinasi beberapa instrumen. Hasil simulasi menunjukkan bahwa skenario ke 12 adalah yang terbaik untuk peningkatan kinerja ekspor produk industri pengolahan kayu primer yang merupakan kombinasi instrumen kebijakan: (1) kenaikan provisi sumber daya hutan, (2) kenaikan dana reboisasi, (3) penurunan suku bunga, (4) penghapusan larangan ekspor kayu bulat, (5) kenaikan upah tenaga kerja, dan (6) kenaikan penawaran kayu bulat domestik. Skenario ke 12 dapat disarankan sebagai suatu kebijakan yang sesuai untuk peningkatan devisa dan juga merupakan representasi dari: (1) kepentingan pemerintah melalui kenaikan provisi sumber daya hutan, (2) kepentingan pengusaha melalui penurunan suku bunga bank dan penghapusan larangan ekspor kayu bulat, (3) kepentingan tenaga kerja melalui peningkatan upah, dan (4) kepentingan lingkungan melalui kenaikan dana reboisasi.

Judul: DNA Extraction and Characterization of Salmonella‟s Lytic Bacteriophage Genome
Abstrak: Bacteriophages are ubiquitous in nature and are known to proliferate wherever their bacterial hosts exist. Their virion particles can exist independently outside the host, however all phages are need their host to propagate. Several phages are highly specific to host cell surface receptors and any slight changes in structure results in little or no interaction between the phage and its host. Salmonella‟s phage isolated from sewage water where their bacteria exist. Three isolated of phages (phages 15, 19 and 38) were used in this research that concentrated using three types of methods. PEG/ NaCl method was firstly used to concentrate the phages based on their molecular weight to precipitate the phage particles during centrifugation. The second method was Scraping Plaque method. In this method, overlay plaques were scraped and collected in SM buffer to get phage concentrates. Enrichment method was the last method used to concentrate the phages. Phage genome isolation was done using two methods i.e. EDTA/SDS and Proteinase K methods. The first method was done using DNase I to eliminate bacterial DNA followed by SDS/EDTA treatment to release phages DNA and phenol-chloroform-isoamyl alcohol to extract the DNA. DNA was collected by isopropanol extraction. While in Proteinase K method, bacterial DNA was eliminated by DNase I and Proteinase K/SDS was used to degrade phages capsids and ethanol for DNA precipitation. The result showed that PEG/NaCl method resulted the highest phage concentration for phage 15 and phage 19, while scrapping method was the highest for phage 38. The quantity and purity of extracted DNA were low for PEG/NaCl and Scraping methods, while Enrichment method was higher indicated higher purity. Run on agarose gel electrophoresis of extracted DNA confirmed that Enrichment method results were the best while scraping and PEG/NaCl method was appeared smear background. Based on DNA genome size determination, the bacteriphages of Salmonella sp were comparable with other study of Salmonella phages. Phage P15 with genome size of 39,5 kb was close to phage epsilon15. Phage P19 with genome size of 41 kb was close to phage ST160. And phage P38 with genome size of 48,5 kb was close to phage Gifsy-1.
