Judul: Pemanfaatan gen RB dalam pengenbangan tanaman kentang tahan penyakit hawar daun (phytophthora infestans)
Abstrak: Potato late blight, caused by Phytophthora infestans is one of the most devastating plant disease. Potato yield losses due to this disease ranged from 47-100%. Frequent intervals and high rates of fungicide spray, currently practiced by potato growers to control the disease are expensive. Host resistance is an alternative control measure that is more economically and environmentally sustainable.

Judul: Pemanfaatan rizobakteri pemacu pertumbuhan tanaman (RPPT) untuk menegndalikan penyakit kerdil pisang (Banana Bunchy Top)
Abstrak: Pisang merupakan salah satu komoditi hortikultura yang merupakan tanaman asli Indonesia. Penyakit kerdil pisang merupakan penyakit paling penting pada tanaman pisang di Indonesia. Virus ini menyerang tanaman pisang secara sistemik sehingga sulit untuk dikendalikan secara langsung. Beberapa cara yang digunakan dalam pengendalian penyakit ini diantaranya dengan penanaman bibit yang sehat, pembongkaran tanaman sakit, pengendalian vektor, dan penggunaan kultivar yang tahan. Beberapa tahun terakhir banyak dilaporkan keberhasilan pengendalian penyakit tanaman menggunakan rizobakteri pemacu pertumhuhan tanaman (RPPT) yang dalam bahasa inggris disebut Plant Growth Promoting Rhizobacteria (PGPR). Penelitian dilaksanakan di Laboratorium Mikologi Tumbuban, Laboratorium Virologi Tumbuhan, dan Rumah Kaca Cikabayan, Departemen Proteksi Tanaman, Fakultas Pertanian, Institut Pertanian Bogor pada bulan Desember 2005 sampai Juni 2006.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
