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: Pengembangan dan implementasi web GIS kampus IPB Darmaga
Abstrak: Bogor Agricultural University, one of universities in Indonesia, has 4 campusses : Dramaga, Baranangsiang, Cilebende, and Gunung Gede. IPB Dramaga Campus (IDC), that be a concern object here, is a wide area campus with identical form building. Searching a room at IDC could be difficult. A dynamic and accesible Geographic Information System of IDC can be considered as a solution. Some previous researches concerned with the same issue. One of them is Web-based GIS of rooms at IPB Campus with Dynamic Mapfile Configuration Using MapServer and Pmapper (Isriana 2008). None of them have been published yet, hence could not be utilized. The objective of this research is developing and implementing Geographic Information System (GIS) of IDC on Linux-OS. By utilizing an open source operating system and PostgreSQL with PostGIS extension made current research different from those of previous researches.

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.
