Judul: Pengembangan Sistem Virtual 3D Gedung Asrama Putra sebagai Media Informasi untuk Mahasiswa Tingkat Persiapan Bersama (TPB) IPB
Abstrak: The Male Dormitory Building of First Preparation Level (TPB) Students is one of the big buildings in Bogor Agricultural University campus. Information on this dormitory building is very important for the prospective new students and their parents who need to know the description of this dormitory. This research developed a virtual reality application to show the Male Dormitory Building in 3D visualization. This application was made by utilizing Google SketchUp, 3Ds Max, and Adobe Director. Google SketchUp was used for creating the basic objects in the building. The texturing, lighting, and animation of these basic objects were done in 3Ds Max. Then, the resulted animation was equiped with Graphical User Interface (GUI) from Adobe Director. The final system is a Desktop Virtual Reality System. This system has been successfully tested to the user and has been proven to be able to display a virtual 3D shape of the Male Dormitory Building.

Judul: Representasi Digital Lanskap Kampus IPB Darmaga, Bogor
Abstrak: Sejak terdapat perkembangan yang pesat di dalam internet, sistem komunikasi berubah menjadi sistem informasi globaL Perubahan ini tidak lain karena makin meningkatnya teknologi WWW (World Wide Web), yang memberikan kemudahan akses ke berbagai sumber multimedia. Kampus IPB sebagai kawasan pendidikan yang memiliki fasilitas lengkap kemudian divisualisasikan menjadi satu sistem informasi digital multimedia dalam bentuk pemodelan lanskap kampus. Sistem informasi multimedia merupakan media yang cukup baik dan representatif dalam memvisualisasikan suatu model sistem informasi. Tujuan utama studi ini adalah untuk membuat model kampus dalam representasi data digital dua dimensi (2D) dan tiga dimensi (3D). ·Berbagai program aplikasi yang digunakan diharapkan dapat memberikan sistem informasi digitallanskap kampus yang cukup memadai untuk IPB. Dalam hal ini dilakukan berbagai macam pemodelan untuk dapat lebih menampilkan lanskap kampus sesuai dengan keadaan nyata (the real world}. Pembuatan model kampus terdiri dari beberapa tahapan kerja yaitu pengumpulan data, persiapan data, proses digitasi, pemodelan 3D dan pembuatan model virtual reality (VR). Berdasarkan data analog berupa peta rencana induk kampus dibangun model digital 2D dan 3D. Model 3D dapat dikembangkan menjadi model lain yaitu model dalam Virtual Reality Modeling Language (VRML) dan model panorama QuickTime Virtual Reality (QTVR). Model 3D yang dibangun dengan program CAD (format DWG) dikonversi ke dalam VRML (format WRL). Setelah dilakukan editing atas kode script dengan teks editor, model VRML dapat ditampilkan pada browser internet dengan menggunakan viewer Cosmo Player. Model panorama QTVR dibangun dengan melakukan perekaman model 3D dari sudut pandang (perspektif) tertentu dalam format bitmap. Setelah dilakukan stitching pada data bitmap kemudian dibangun model QTVR dengan

Judul: Mercury Toxicity and It’s Effect on Histopathology Change of Nile Tilapia (Oreochromis niloticus).
Abstrak: Nile tilapia (Oreochromis niloticus) is one of fish species that oportunity to contaminated with mercury. The effects of pollutants can damage living organisms organs and can cause death. The effects caused mercury had acute or chronic character. The aims of this study are to determine threshold and acute toxicity of mercury chloride (HgCl2) of Nile tilapia (Oreochromis niloticus), to assess the effect of mercury chloride (HgCl2) on several biometric parameters (survival, growth rate of average daily weighted, liver condition, bile and reproductive variability of Nile tilapia (Oreochromis niloticus), assess the level of damage to the histological structure of the gills, liver and kidney of Nile tilapia (Oreochromis niloticus) caused mercury chloride (HgCl2) exposure. This study was conducted from February to June 2013. Nile Tilapia (Oreochromis niloticus) were used in this study were female with average weight 20 grams or 11-13 cm length range. Toxicant materials used in this study was mercury chloride (HgCl2). Fish were reared in each aquarium 60x40x30 containing 48 liters of water. This study consists of three stages: a preliminary test, acute test, and sub-chronic test. To determine the changes in biometric condition of tilapia approximated by measuring the survival rate (SR), the growth rate of average daily weight , the content of mercury in the fish organs, hepatosomatic index (HSI), the relative bile volume (VER), gonadal soamtic index (IKG), fecundity and oocit diameter, tissue damage caused by mercury in fish organs by making histological preparations stained with hematoxylin and eosin. The median lethal concentration (96 hr, LC50) of Mercury Chloride was calculated as 1,64 mgL--1.The survival rate was highest in the control treatment (46,67 %) . Mercury chloride with concentration 0.196 mgL--1 show significant effect to changes HSI and relative bile volume, and oocyte diameter of Nile tilapia (p < 0,05). Mercury chloride with a concentration of 0,164 mgL-1 and 0,196 mgL-1 have not a significant effect on the growth rate of weight, gonadal somatic index and fecundity of Nile tilapia (p > 0,05). Mercury chloride cause damage to gills (hyperplasia, hypertrophy, proliferation and neukrosis), liver (hyperplasia, hemorhage, shrinkage of hepatocytes, proliferation and neukrosis) and kidney (hyperplasia, hemorrhage, shrinkage of the glomerulus, proliferation and neukrosis).
