Judul: Modul Visualisasi Menggunakan GeoExplorer dalam Sistem Informasi Berbasis Web untuk Data Titik Panas di Indonesia
Abstrak: Forest fire is a serious problem because it can cause negative impacts for the environment. One of the forest fire prevention efforts is to build a web-based geographic information system (GIS) to manage historical hotspot data as indicators of fire occurrences. A web-based GIS for hotspots distribution in Indonesia was developed using OpenLayers in the previous research. The GIS still has several limitations in providing an attractive user interface. Therefore, in this study we created a visualization module in the GIS for hotspot distribution using GeoExplorer. With the visualization module, users can interactively explore the maps of hotspot distribution. In addition, historical hotspots data can be easily managed so that the system can assist users in obtaining summaries of historical hotspots data for the regions in Indonesia. The improved GIS presents summaries of hotspots data in forms of maps, graphs, and tables. The system also has additional supporting features in the visualization module using OpenLayers and GeoExplorer.

Abstrak: Forest fire can be periodically detected by satellite as hotspot areas that occur at specified time and location. The frequency of forest fire in Indonesia is high so the data collection of hotspots will be very large. That data collection of hotspots can be stored into specific storage such as data warehouse. A data warehouse system of forest fire was built in the previous research using GeoServer as web map server and GeoMondrian as OLAP Server. However, that system still has some limitations such as the poor system runtime and the low amount of retrieved hotspots. In this research, the system would be reconfigurated in order to fix those limitations so that the system performance would increase. The configuration involves some part of the system including Java Runtime Environment, database source, data cube schema, and error handling in OpenLayers. It has resulted 155 ms higher speed of runtime and 1310 higher number of retrieved hotspots.

Judul: Essential Fatty Acid Requirements of Catfish (Clarias batrachus Linn.) for Broodstock Development
Abstrak: This experiment was conducted to determine essential fatty acid requirements of catfish (Clarias batrachus Linn.) for broodstock development. The basic diet supplied to the test fish had protein and fat content 46.51 - 48.29% and 5.8 - 5.96% respectively. The five test diets differed in the essential fatty acid (EFA) level. Diet A contained 0.21% (36-fatty acid and 0.03% S3-fatty acid; diet B 0.67% d6-fatty acid and 2.09%&3-fatty acid; diet C 2.24KU6-fatty acid and 0.07%&3-fatty acid; diet 0 1.85%(;36-fatty acid and 0.56% a3-fatty acid; diet E 0.26% a6 fatty acid and 1.68% d3-fatty acid. Most of US-fatty acid in diet B and D were 1$:3 (33, on the other hand those in diet E were 20:s c33 and 22:6 W3.
