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.

Judul: Sistem Informasi Geografis Berbasis Web untuk Data Histori Hotspot di Indonesia Menggunakan OpenGeo Suite 3.0
Abstrak: Forest fire is a serious problem because it causes many negative impacts to the environment. One of the activities to prevent forest fire is to develop a web-based geographic information system (GIS) to manage the historical hotspot data as an indicator of fire. In this research, web based GIS was developed using OpenGeo Suite software. OpenGeo Suite is an application which bundles PostgreSQL database management with PostGIS spatial extension and Geoserver map server so that the web-based GIS is easy to develop and manage. The GIS which was developed provides several main features, including displaying the map of Indonesia, pan map, zoom in, zoom out, and searching functions for hotpot data based on region and time. Using the web based GIS, hotspot historical data can be easily managed in order to assist users in providing summaries of historical hotspot data in Indonesia.

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.
