Judul: Sistem Informasi Geografis Persebaran Hotspot Propinsi Kalimantan Tengah Menggunakan Framework Pmapper
Abstrak: There are several sites that provide information about hotspot distribution in Province of Central Kalimantan based on data up to December 2009, such as www.pkhl.or.id and www.geospasial.bnbp.go.id. However, these sites only provide information in the form of tables or static map (image in JPEG 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 searching hotspot distribution by time interval. Therefore, the Geographic Information Systems of Hotspot Distribution in Province of Central Kalimantan is developed as the solution to these problems. This Geographic Information System of Hotspot Distribution in Province of Central Kalimantan 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 8.3, 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 Hotspot Distribution in Province of Central Kalimantan is developed as an improvement to Pmapper features, this research added facility to search hotspot by time interval, provides information about the locations of hotspot distribution in the Province of Central Kalimantan in full, web-based, dynamic and interactive form. The included informations are regional boundaries, contour line, roads, rivers, lakes, coastline, airport, and cities.

Judul: Sistem informasi geografis persebaran titik panas Provinsi Kalimantan Tengah menggunakan PHPMapscript
Abstrak: Forest fires is one of the serious problem that occurred in Indonesia. It can cause loss of both material and non-material such as death, property damage and even destruction of ecosystems. One of the prevention efforts to stop the forest fires spread is by building a system which can monitor and display hotspot. In 2010, Indri developed Geographic Information System of Hotspot Distribution in Province of Central Kalimantan. However, the system that had been built was not able to search down to sub-district level. Therefore, the goal of this research is to add a searching function until to subdistrict and presenting data in a graphical form. This Geographic Information Systems of Hotspot Distribution in the Province of Central Kalimantan is developed by using the GIS Development Guide published by the Department of Geography at Buffalo, on Microsoft Windows platform using PHPMapscript, PostgreSQL 8.2, PostGIS 1.4.0, and MS4W 2.3.1. This information system is built as a system to provide information about spreading of hotspot and show the total of hostpot in each subdistrict using the graphical form. The included informations are regional boundaries, contour line, roads, rivers, lakes, coastline, airport, and cities.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
