Abstrak: Information concerning areas that are potential for soybean production is not provided in an interactive information system that can be easily accessed by public. Nowadays, information about soybean production in all districts in Indonesia is displayed in the tabular form in the website http://aplikasi.deptan.go.id/bdsp. For that, in this study, a web-based geographic information system (GIS) was developed to manage and visualize soybean production in all districts in Indonesia. K-means clustering was performed to group data on production, productivity and harvested areas of soybean to make the coloring process become easier in GIS. The best clustering was obtained with 4 clusters and the sum square error (SSE) were 2.07, 1.53, and 0.0037 for data on production, productivity, and harvested areas of soybean, respectively. The GIS was developed using OpenGeo Suite 3.0 as the geospatial tool for managing and providing information about soybean production in Indonesia in forms of maps, tables, and graphs based on the results of k-means clustering.

Judul: Sistem Informasi Geografis Berbasis Web untuk Produksi Padi di Indonesia Menggunakan OpenGeo Suite 3.0
Abstrak: Rice is an agricultural commodity which plays an important role in economy and becomes a main food for Indonesian people. Currently, Java Island provides the largest contribution in paddy production. Ministry of Agriculture has provided information regarding paddy production in Indonesia that can be accessed by public. The existing representation of paddy production information is less interactive because the information is provided only in the tabular format. In this study, web-based geographic information system (GIS) was developed using OpenGeo Suite 3.0 software. OpenGeo Suite 3.0 is an application which bundles PostgreSQL with a spatial extension PostGIS as a database management system to interactively display information on the spread of paddy production in Indonesia and GeoServer as map server. The GIS displays information about production, productivity, and harvested areas of paddy in the form of tables, maps, and graphs. The system is useful to facilitate the public in accessing information regarding paddy production in all districts in Indonesia.

Judul: Light Microscope Study of ConnectiveTissue in The Spleen of Common Rousette Bat (Rousettus amplexicaudatus)
Abstrak: The spleen is the largest lymphoid organ. As a secondary lymphoid organ, in addition to its immune function, the spleen also has functions as blood filtration, storage, and hematopoiesis. The spleen has different morphologies between species that support different physiological functions, one of which is the difference in the structure of the capsule and trabeculae. Capsule and trabeculae of the spleen generally consist of connective tissue and smooth muscle. The thickness of smooth muscle composed together with connective tissue in the capsule and trabecula determines the function of the spleen that is divided spleen into three storage, defense, and intermediate. Bats are the reservoir of various zoonotic diseases. Bats are thought to have unique immune systems compared to other mammals but the characteristics of its immune organs such as the spleen have never been studied before. This study was conducted to examine the characteristics of capsulae and trabecula of the Common Rousette (Rousettus amplexicaudatus).
