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: Geographic Information System of Bogor Facilities Using Pmapper Framework.
Abstrak: There are several sites that provide information about location of points of interest in the City of Bogor based on data up to February 2009, such as www.kotabogor.go.id, www.indotravelers.com, www.pu.go.id, www.asiamaya.com, and www.bogor.net. However, these sites only provide the information in the form of tables or static map (image in JPEG or TIFF format) which is not displayed in a full and complete form. Another problem is that the information provided through this map is not informative enough and can not show the locations in the form of dots on geographic areas of Bogor City. Therefore, the Geographic Information Systems of Bogor City Facilities is developed as the solution to these problems. This Geographic Information Systems of Bogor City Facilities is developed by using the GIS Development Guide published by the Department of Geography at Buffalo, on Microsoft Windows platform using Pmapper framework 3.2.0, PostgreSQL 8.2, PostGIS 1.2.1, and MS4W 2.3.1. The functions of this system are to zooming in/out the map, searching for locations, printing a map in the form of PDF or HTML, adding a new object and retrieving information related to the location. The Geographic Information Systems of Bogor City Facilities is developed as a system that provides information about the locations in the city of Bogor in full, webbased, dynamic and interactive form. The included locations are villages, districts, landuse, roads, rivers, government facilities, public services, major businesses as well as tourism sites.

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.
