Judul: Geographic Information System of Optimal Travel Route in Bogor City Using Pmapper Framework
Abstrak: Nowadays, time becomes something that very valuable, for example, the time that is used for traveling. The shortest distance of the traveling, can make the time more efficient. Sometimes travel route has an alternative route, so the travelers have to choose the route that will be through with. Usually the travelers will choose the optimal traveling route, which is the shortest distance and less travel time. Genetic algorithm approach can be used to find the optimal route. Genetic algorithm will be implemented to find the optimal route from the starting point to the destination point. Optimal route that generated by genetic algorithms needs to be visualized to the map format for the users to know the traveling route that has been through clearly. This paper presents the Geographic Information System of Bogor City (SIGKABO) as the solution to visualize the optimal route in the map format. SIGKABO developed by using Pmapper framework on Windows platform with PostgreSQL 8.3 and PostGIS 1.3.5 as a database management system and MS4W as a map server. The system visualize the optimal route according to its real condition. The system displays the route with the buildings and facilities around the road so users can identify the location of the road that must be passed. We can conclude that the SIGKABO works well to visualize the optimum route based on result of testing procedure.

Judul: Sistem Informasi Geografi Pariwisata dan Sarana Publik Kota Bogor Portable Menggunakan Framework Pmapper
Abstrak: The presentation of information on tourism and public facilities in the city of Bogor to the community in general and in particular Bogor society becomes important. In that case we need a media that can provide information on all aspects related to tourism and public facilities in the city of Bogor. It would be better if the media allows the public to obtain the information needed quickly and easily for distribution. This study aims to build a Geographic Information System of Tourism and Public Facilities in the City of Bogor Portable using spatial database development, with a presentation that is easily accessible by all parties without restrictions of space and time. The information is presented in the form of maps and textual information on Tourism and Public Facilities in the City of Bogor. This system has a weakness during the process because the access time is longer than the system that run directly on the computer

Judul: Pelumas Aktif Dengan Bahan Dasar Minyak Ikan Dan Aditif Znochitosan Particle.
Abstrak: Pelumas memiliki peranan penting dalam meminimalkan fungsi keausan pada sistem mekanik. Synthetic liquids, minyak nabati (biolubricant) serta berbagai aditif telah banyak digunakan. Karakteristik minyak ikan dan sifat fungsional chitosan yang dapat berperan sebagai aditif, merupakan peluang dalam pengembangan pelumas baru yang ramah lingkungan. Tujuan penelitian adalah melakukan pembuatan dan karakterisasi pelumas aktif dengan bahan dasar minyak ikan dan aditif partikel ZnO-chitosan. Minyak dasar pelumas dibuat melalui reaksi epoksidasi minyak ikan dengan karakteristik bilangan oksiran (4,74±0,09) %, bilangan iod (49,91±1,9) gI2/100g, bilangan peroksida (59,33±3,05) meq/kg, dan asam lemak bebas (11,07± 0,10) %. Kombinasi aditif ZnO 0,5% dengan partikel chitosan 0,5% memberikan pengaruh terhadap pelumas minyak ikan dengan karakteristik terbaik, berupa scar diameter (1,16±0,04) mm, viskositas kinematik pada suhu 40°C (66,50±0,35) mm2/s dan korosi bilah tembaga grade 1A.
