Judul: Virtual Tour 360 pada RIA Campus Tour 3D IPB Darmaga
Abstrak: Bogor Agricultural University uses virtual world as a medium to share the information. A previous research has made an application that represent place information and visualization of IPB. However, the application is not able to provide visualization and virtual experience optimally because the user can not see the actual surroundings. Therefore, this research will develop Rich Internet Application by adding a Virtual Tour 360. Virtual Tour 360 is a simulation of a location consisting of a sequence of images that are not interrupted. The objective of this research is to implement Virtual Tour 360 in RIA Campus Tour 3D IPB by adding a Virtual Tour 360 module. The construction of Virtual Tour 360 is adjusted to locations in RIA Campus Tour 3D IPB. The photos obtained is used as the panoramic images using Autostitch software. Virtual Tour 360 was developed using jQuery. The result of 30 questionners given to respondens indicated that the addition of Virtual Tour 360 on the RIA Campus Tour 3D IPB can help visitors to know the locations in IPB

Judul: Pengembangan sistem virtual room navigator dengan visualisasi 3D : studi kasus pada gedung perpustakaan IPB
Abstrak: Sistem navigator ruangan virtual dengan visualisasi tiga dimensi (3D) merupakan sistem yang dapat merepresentasikan bangunan sesuai dengan keadaan di dunia nyata. Interaksi antara pengguna dan sistem dilakukan seperti halnya dalam kehidupan manusia sehari-hari. Sistem yang demikian memberikan pengalaman virtual dan kesan lebih kuat bagi pengunjung baru. Sistem ini sebagai sumber informasi alternatif bagi pengunjung baru tentang tata ruang dan tata letak di dalam bangunan. Suatu bangunan yang berukuran besar dan memiliki banyak ruangan sering menyulitkan pengunjung baru. Oleh karena itu dibutuhkan sumber informasi untuk membantu pengunjung baru. Informasi yang disajikan berupa visualisasi informasi spasial. Selain itu sisiem ini juga dapat digunakan sebagai salah satu alat presentasi kepada tamu-tamu. Sistem dikembangkan menggunakan metode Engineering Development Life-Cycle with added HCI awareness. Dengan menggunakan metode ini diharapkan dapat terpenuhi kemampuan fungsional sistem dan juga interaksi antara pengguna dan sistem. Pengembangan sistem ini mencakup implementasi pembangunan obyek 3D bangunan virtual dan pemrograman untuk manajemen dan bernavigasi. Antarmuka sistem menggunakan form jendela seperti pada umumnya. Secara spesifik sistem dikembangkan guna membantu pengunjung baru Gedung Perpustakaan IPB untuk berorientasi terhadap ruangan-ruangan di dalamnya. Pengguna dapat bernavigasi di dalam lingkungan 3D yang merupakan miniatur virtual Gedung Perpustakaan IPB.

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).
