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: 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: The Isolation of Silver (Ag) from Fixer Sludge with Electrolysis methode
Abstrak: with the variations concentration, electrode of carbon, and voltages. The aim of research are looking for the easiest and eficient electrolysis. Among of 272.79 ppm of silver (impurities) could be produced from electrolysis fixer which used 300 times maintain the film. For 400, 500, and 600 times electrolysis were produced recently 49.42, 137.04, and 55.22 ppm. Futhermore, it was increased to 220.00 ppm from 700 times. These were possible because of density the solutions. From the electrode of carbon, 68.2222 g Ag (impurities) could be processed from size 14 cm x 3 cm x 3 cm. The next results 41.2050 g and 43.7559 g from the sizes 16 cm x 3 cm x 3 cm and 18 cm x 3 cm x 3 cm. The reasoned of this part any faster reaction on the most litle electrode. By the way, from voltages variation, the processed showed that 47.4575 g of Ag (impurities) could be produced from 11 volt. It’s caused the bigest voltages are also the bigest kinetics power on the reactions. Sampel and product were analized by AAS. Consentration has potential to be indicator, because of the used 700 times was given trend high Ag (impurities) became increase optimally at 11 volt, and much sediment that is 47.4575 g. The best rendemen is 13.33%. The other finding is that the strength of the time and the voltages strongly enfluence the electrolysis shown by the bigger result on F(calculation) than that of the F(table).
