Judul: Pemasaran Mebel Kayu Jati Jepara
Abstrak: Industri perkayuan memegang peranan penting terhadap perolehan devisa dan pembangunan ekonomi negara. Sejalan dengan penuruan ketersediaan bahan baku untuk industri dan meningkatnya biaya tenaga kerja pada industri berbasis kayu maka mebel kayu merupakan industri kecil yang berpeluang untuk dikembangkan. Industri mebel kayu tidak hanya diharapkan untuk memperoleh devisa tetapi juga akan menstimulasi pertumbuhan ekonomi nasional karena memiliki nilai tambah yang tinggi, mempunyai keterkaitan yang cukup kuat dengan sektor lain, menciptakan lapangan kerja, memiliki pertumbuhan pasar yang baik, dan berdaya saing cukup tinggi. Data statistik UN COMTRADE (2008) mermperlihatkan bahwa sektor industri mebel terus mengalami peningkatan ekspor mebel dari tahun 2003 sampai tahun 2007. Negara tujuan ekspor mebel Indonesia yang utama adalah Amerika Serikat (37%), Jepang (12%), Inggris (8%) dan Belanda (8%), Jerman (7%), dan Perancis (7%). Selain itu, ekspor juga ditujukan ke negara-negara Italia, Belgia, Spanyol, dan Australia.

Judul: Rantai Nilai (Value Chain) Mebel Kayu Mahoni Jepara
Abstrak: Industri mebel umumnya termasuk dalam industri kecil dan menengah. Penerimaan negara yang berasal dari ekspor mebel terus mengalami peningkatan selama tahun 2000 – 2005 sebesar 17%, dimana pada tahun 2005 jumlah ekspor mencapai US$ 1,01 milyar - 1,78 milyar. Mebel kayu termasuk mebel kayu mahoni merupakan 75% dari nilai ekspor tersebut. Dalam perdagangan global selama tahun 2003 - 2005, mebel Indonesia menguasai 2,5% dari pangsa pasar dunia. Dengan masuknya semua jenis mahoni dalam Appendix CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) II yang berimplikasi terhadap pembatasan pemanenan mahoni di tempat tumbuh aslinya, maka kondisi ini merupakan peluang bagi Indonesia untuk meningkatkan produksi mebel mahoni dalam rangka memenuhi pasar.

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.
