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: Sistem informasi geografis pencarian ruang kuliah kampus IPB Darmaga
Abstrak: IPB has the building architecture which is almost equal to a fairly wide area and sometimes a lot of academicians are confused and have difficulty in finding the intended lecture room. In this research, we built a web-based system using the system development life cycle which presents geographic information that can help facilitate the academicians in search of lecture room at IPB. The geographic information system is built using Pmapper. The results of this research is a system which displayed room information in a table with function of filtering, searching, paging, delete, edit, add data, and in the form of a map with the features on Pmapper with function of coordinates, legends, searching, zooming to extents, back, forward, zoom to selected, zoom in, zoom out, pan, identify, select, tool tip, refresh folder, point of interest, download, and export to CSV / PDF. Based on the test results, this system has worked well in accordance to the user needs to facilitate them in searching lecture room at the IPB Darmaga campus.

Judul: Sintesis Senyawa Tetrazola dari Asam Lemak Jenuh.
Abstrak: Senyawa tetrazola merupakan senyawa penting yang banyak digunakan dalam bidang farmasi sebagai obat, bahan bakar jet, ligan pembentuk senyawa koordinasi, dan prekusor pembentukan senyawa heterosiklik lainnya. Senyawa tetrazola dapat disintesis dari minyak nabati melalui senyawa nitril. Penelitian ini bertujuan mengonversi langsung asam lemak jenuh menjadi senyawa lemak tetrazola. Hasil penelitian ini, diharapkan dapat meningkatkan nilai tambah dari minyak nabati. Sintesis dilakukan dalam 2 tahap pada kondisi yang berbeda. Kondisi optimum untuk membentuk nitril pada suhu 295 ºC selama 5 jam dengan kondisi atmosfer nitrogen menghasilkan senyawa nitril sebesar 60─90%. Kondisi yang digunakan untuk reaksi pembentukan tetrazola adalah pada suhu 120 ºC selama 10 jam dengan hasil reaksi 30─50%. Kemurnian lemak nitril dan tetrazola yang diperoleh dengan metode ini ditunjukkan dengan hasil kromatogram kromatografi lapis tipis, spektrum inframerah transformasi fourier, spektrum resonans magnet inti, dan titik leleh.
