Judul: Rich Internet Application Tur Kampus Tiga Dimensi Institut Pertanian Bogor
Abstrak: Problem of location information has became a general thing that happens in every place, especially in locations that are spacious and have lots of room. Problems posed related to the ease of new visitors in exploring the place for the first time. This problem can be solved by the application of information which represents a place and a more interactive visualization. RIA Rich Internet Application (RIA) is a suitable technology to create interactive applications in terms of information or visualization. RIA is divided into two categories based on the framework: a framework based on JavaScript / AJAX and framework based on plug-ins. This study presents the application of RIA IPB web based campus tour. This application uses framework based on plug-ins. Application interface is designed to resemble a map. The application displays a 3D map of IPB to the user and displays information of important places in IPB. In addition, this application can trace the path in the map to give the impression of exploration for user. The pathway is formed by the Bezier curve equation in the XY fields, XZ fields, ZY fields. The formed lines can be manipulated based on the X, Y, and Z coordinates

Judul: Sistem Informasi Geografis 3 Dimensi Berbasis Web Kampus IPB Darmaga Menggunakan Three.js.
Abstrak: Kampus Institut Pertanian Bogor (IPB) Dramaga memiliki wilayah yang luas serta gedung dan ruangan yang banyak tersebar di setiap fakultasnya. Informasi terkait pemetaan wilayah kampus IPB Dramaga yang tersedia kurang detail, sehingga tidak efektik untuk membantu civitas akademik atau pengunjung dalam mencari lokasi tertentu. Permasalahan yang sering terjadi adalah sulitnya mencari ruangan atau tempat tertentu di lingkungan kampus IPB Dramaga. Penelitian ini bertujuan mengembangkan sistem informasi geografis (SIG) berbasis web dengan menggunakan Three.js untuk memetakan Kampus IPB Dramaga yang ditampilkan dalam model 3 dimensi. Sistem informasi geografis tersebut dikembangkan menggunakan metode web development life cycle (WDLC). Penyajian sistem informasi geografis 3 dimensi dibangun menggunakan framework Three.js dalam bentuk plugin yang tersedia pada perangkat lunak QGIS. Sistem informasi geografis ini bertujuan untuk dapat membantu civitas akademik atau pengunjung kampus untuk mendapatkan informasi lokasi yang dituju dengan mudah dan cepat.

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).
