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: 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: Karakteristik Carboxymethyl Chitosan Dengan Variasi Konsentrasi NaOH
Abstrak: Carboxymethyl chitosan is chitosan derivative product obtained from chemical modification. CMCh were made by alkalization process and carboxymethylation process. Factors that affect CMCh characteristics were excess sodium hydroxide in alkalization process, ratio between chitosan and monochloroacetic acid, and carboxymethylation temperature. The objectives of this research were to study the NaOH effect to CMCh characteristics, to learn process of making CMCh, to set the proper concentration of NaOH, and to analyze CMCh characteristics. CMCh yields were 110.72%-114.22%. CMCh pH value were 3.74-4.31. The optimum NaOH concentration to obtain the best CHCh was 10 M. Percentage of CMCh moisture content was 10.70%-11.42%. Ash content and nitrogen content of CMCh were 0.49%-0.50% and 4.52%-4.81%. CMCh viscousity was 8.25 cps. Percentage of CMCh solubility was 61.61%-91.50%. The different functional groups from chitosan which observed in CMCh were C=O group, CH group from alkene functional group, C−O group, and C−O−C group.
