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: 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.
