Judul: Perubahan Beberapa Sifat Fisik Tanah dan Pertumbuhan Tanaman Kedelai (Glycine Max L. Merril) akibat Pemberian Kapur dan Bahan Bumat dari Air Gambut pada Tanah Latosol
Abstrak: The purpose of this study is to see the effect of lime and humic substance application on: 1) soil aggregate stability, soil water characteristic (water content at pF1, pF2, pF2.54 and pF4.2), 2) Water movement on unsaturated soil, such as advance of wetting front, soil conductivity and difusivity, and 3) the growth of soya bean. This study was conducted on March 1999 until January 2000 at soil physic laboratory of IPB and Puslittanak for soil physical characteristic measurement and green house of IPB baranang siang for crop growth experiment. Soil sample used in this study is Latosol and humic substance used were obtained from peat soil from the area of PT. SAC Nusantara Mesuji.

Judul: Pengaruh pemberian kapur pada kandungan air tanah yang berbeda terhadap pertumbuhan dan produksi kedelai (Glycine max. (L.) Merr)
Abstrak: Dalam usaha meningkatkan produksi tanaman kedelai maka dilakukan percobaan Pengaruh Pemberian Kapur pada Kandungan Air Tanah yang Berbeda terhadap Pertumbuhan dan Produksi Kedelai (Glycine max (L.) Merr) dari bulan No- pember 1985 sampai dengan April 1986 dengan tujuan untuk mengetahui pengaruh Pemberian Kapur dan Kandungan Air Ta- nah selama pertumbuhan tanaman serta interaksinya terha dap pertumbuhan dan produksi serta serapan N, P, K, Ca dan Mg. Percobaan ini terdiri dari dua macam percobaan dengan, menggunakan Rancangan Faktorial 4 x 3 dan 3 x 3 x 2 dalam Rancangan Acak Lengkap dengan masing-masing ulangan 3 dan 2 kali. Perlakuan pada percobaan pertama terdiri dari tingkat kandungan air tanah yaitu 50, 75, 100 dan 125 W kapasitas lapang (At. Atg. Aty, At, dan takaran kapur 0.5 1.0 dan 1.5 Alaa dengan menggunakan varietas Orba. Percobaan kedua terdiri dari 3 tingkat tegangan air tanah. (6, 0.4, 0.2 atm), perlakuan kapur sama dengan percobaan pertama dan varietas diganti dengan varietas Galunggungdan Wilis. Untuk menjamin kondisi optimum bagi pertumbuh- an tanaman diberikan pupuk dasar N, P dan K (50 150 50) log per hektar serta pengendalian hama dan penyakit. Untuk marangaang pertumbuhan bintil akar diberikan Rhizobium de- ngan dosis 5 g untuk 1 kg benih..dst

Judul: Antibodi anti-idiotipe sebagai kandidat vaksin rabies, Anti-idiotype andibody as a rabies vaccine candidate
Abstrak: Anti rabies serum (ARS) called antibody 1 (Ab1) was used as the antigen to immunize laying chickens. Anti-Ab1 chicken immunoglobulins (IgY), the antiidiotype antibodies against rabies (Ab2) was isolated from chicken blood every week for ten weeks. The highest titer of Ab2 was found at the third week after the last immunization. Immunoglobulin Y was separated by means of ammonium sulfate precipitation, then dialyzed using PBS pH 8.0 for 24 hours at 2 – 8 oC and purified using affinity chromatography column for IgY lead the proteins molecules with 185,000; 95,000 and 49,000 dalton in weigth. Purified IgY was used to immunize New Zealand White rabbit and the antibody response (Ab3) was detected using Agar Gel Precipitation Test (AGPT). The Ab3 showed specific reaction with Ab2 as well as rabies virus. Interestingly, Ab2 and rabies virus express partial identity reaction. This lead the insight, that not all parts of Ab2 are internal image of rabies virus. The efficacy of Ab3 was detected using enzyme linked immunosorbent assay (ELISA) and indicated that the level of Ab3 titer is protective according to WHO standard (more than 0.5 IU/ml). The conclusion of this study is the anti-idiotype antibody can induce protective immune response against rabies virus and can be used as an alternative for rabies anti-idiotype vaccine. Key words : anti-idiotype vaccine, antibody, rabies
