Judul: Analisis Sosial Ekonomi Pencurian Kayu (Studi Kasus  Kabupaten Blora Jawa Tengah)
Abstrak: Pencurian kayu jati merupakan penyebab kerusakan terbesar dari hutan yang ada di Pulau Jawa, dan menjadi penyebab kerugian paling besar bagi Perhutani, dibandingkan dengan kebakaran, bibrikan, penggembalaan liar dan bencana alam. Di Kabupaten Blora Propinsi Jawa Tengah, dalam kurun tahun 1997 - 2001 rata-rata intensitas pencurian kayu mencapai 9.807 kasus/tahun, dengan kerugian fisik berupa hilangnya pohon hunggak rata-rata mencapai 87.518 tunggak/tahun, dan kerugian finansial rata-rata Rp. 12,1 Milyar/tahun.

Judul: Pengaruh faktor sosial ekonomi masyarakat terhadap tingkat pencurian kayu : Studi kasus di KPH Blora, Cepu dan Randublatung
Abstrak: Di Pulau Jawa yang berpenduduk 105,7 juta jiwa, luas kawasan hutannya meliputi sekitar 3 juta hektar, atau 23% dari luas daratan (Perum Perhutani, 1995). Pengelolaan hutan di Pulau Jawa ini dilaksanakan oleh Perum Perhutani, yang memiliki tujuan menjamin kelestarian sumberdaya hutan (sustainability), memperoleh keuntungan perusahaan optimal (profitability), meningkatkan kesejahteraan masyarakat sekitar hutan (prosperity) dan meningkatkan lingkungan hidup. Dengan tingkat kepadatan penduduk yang semakin tinggi dan semakin terbatas daya dukung lahan, maka hutan merupakan faktor penting dalam menunjang kesejahteraan masyarakat. Sehingga muncul tekanan-tekanan yang mengancam lahan hutan tersebut. Tekanan-tekanan ini akan menyebabkan timbulnya masalah penyerobotan tanah, perencekan hutan, penggembalaan liar, pencurian hasil hutan dan sebagainya. Salah satu masalah yang menimbulkan kerugian yang cukup besar adalah tingkat pencurian kayu. Penelitian ini bertujuan untuk mengetahui gambaran umum tingkat pencurian kayu di KPH Blora, Cepu dan Randublatung, mengetahui faktor-faktor penyebab terjadinya pencurian kayu terutama faktor-faktor sosial ekonomi masyarakatnya. Faktor-faktor sosial ekonomi didekati melalui jumlah penduduk, pendapatan per kapita penduduk, luas kepemilikan lahan, tingkat pengangguran penduduk, tingkat pendidikan penduduk dan tingkat religius penduduk. Hipotesis penelitian adalah bahwa faktor sosial ekonomi masyarakat berpengaruh terhadap tingkat pencurian kayu.

Judul: Bivalent vaccine for Motile Aeromonas Septicemia and Streptococcocis in Nile Tilapia (Oreochromis niloticus)
Abstrak: Etiological agents of common fish diseases are the Gram-negative Aeromonas hydrophila and the Gram-positive Streptococcus agalactiae, both are considered severe fish pathogens on account of their ability to cause damaging disease outbreaks in Nile Tilapia (Oreochromis niloticus). The occurence of co-infections between A. hydrophila and S. agalactiae at Waduk Cirata was about 20% per populations. Clinical signs appeared soon after infection, and include depression or excitability, anorexia, C-shaped body posturing, erratic swimming and whirling, and death. Aeromonas hydrophila and S. agalactiae cultures were not able to inhibit each other and showed negative results from antimicrobial activity, both are succeptible to antibitoics Tetracycline and Chloramphenicol. Nile Tilapia also were clinically examined and necropsied for histopathology, samples were taken from kidney, brain, liver, and spleen. Histopathological lesions were grouped into two characteristic patterns. The first pattern consisted focal lesion and inflammation. The second pattern consisted of multifocal lesion, necrotic, and inflammatory lesions resulting organ deformation. The mortality patterns of Nile Tilapias showed acute and chronic infections to Motile Aeromonas Septicemia, sub-acute infection to Streptococcocis. There was a homeostatic balances on hematological respons during co-infection. Aeromonas hydrophila AHL0905-2 and Streptococcus agalactiae N14G, were used as an inactivated A. hydrophila and S. agalactiae vaccine. Different vaccine preparations and formulations for vaccination of Nile Tilapia species were tried by adding neutral buffered formalin 3% to the bacterial culture (bacterin). The safety of formalin inactivated vaccine is still questionable by some aquaculture practitioners, but the sterility and safety test results of the bivalent vaccine was safe to use through intraperitoneal injection route. An antibody response was detected at the 1st week that rose significantly (p<0.05) at the 3th week post immunization in all the immunized groups. Similarly, there were significant difference (p<0.05) in the humoral immune response between groups immunized with single and mixed bacterial antigens. Upon challenge with single pathogen, a high relative percent survival was recorded in the group immunized with mixed bacterial antigens and was comparable to those fish immunized with the single bacteria. The value of relative per cent survival from bivalent vaccine mixed whole cell+ECP was 100% and 86.2% to single infections and 56.7% to co-infections, indicate that this vaccine was eficient in Nile Tilapia.
