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: 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: 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.
