Judul: Web GIS ruangan IPB dengan konfigurasi Mapfile dinamis menggunakan Mapstorer dan Pmapper
Abstrak: Institut Pertanian Bogor (IPB) merupakan salah satu perguruan tinggi di Indonesia yang memiliki area kampus yang cukup luas. Permasalahan yang seringkali terjadi yaitu pencarian suatu ruangan di lingkungan kampus IPB Darmaga. Salah satu solusi dari pernasalahan tersebut adalah dengan membangun suatu Sistem Informasi Geografis (SIG) berbasis web. Sistem yang telah dibuat sebelumnya yaitu Sistem Informasi Ruangan Kampus IPB Darmaga (Nasution 2007) masih bersifat statis dalam melakukan konfigurasi perancangan peta yang akan ditampilkan. Pengembang sistem harus mengetahui dengan tepat baris-baris teks di dalam file perancangan peta. Dengan bantuan framework Mapstorer, perancangan peta dapat dilakukan melalui antarmuka grafik sehingga lebih memudahkan pengembang dalam melakukan pengubaban konfigurasi perancangan peta yang akan ditampilkan.

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: Peptides Hydrolysate Derived from Collagen of Snakehead Murrel (Channa striata) Skin Demonstrate Anti-oxidant and Anti-cholesterol Activities.
Abstrak: Anti-cholesterol and anti-oxidant play crucial role to combat cardiovascular disease (CVD) related to formation of arterial plagues from oxidation of cholesterol. In the past decades, research on bioactive peptides demonstrating anti-cholesterol and anti-oxidant activities have been reported as the alternative drugs. In this study, acid soluble collagen was extracted from the skin of snakehead murrel and employed to induce production of collagenase by Bacillus licheniformis F11.4. The collagenases secreted were in turn purified through AKTA Purifier (ion exchange, DEAE column) and used to produce peptides hydrolysate. The purified enzymes were grouped in two distinct collagenase fractions, designated as fraction D and F. Peptides hydrolysate produced by the fraction D was found to demonstrate HMG-CoA inhibitor activity comparable to pravastatin and limited anti-oxidant activity. Meanwhile, peptides hydrolysate generated using the fraction F demonstrated anti-oxidant activity comparable to BHT (2mM), vitamin C (2mM) and vitamin E (2mM), but limited HMG-CoA activity. Combination of the fraction D and F resulted in substantial HMG-CoA inhibition and anti-oxidant activities.
