Judul: Prototipe Sistem Informasi Geografi Pemanfaatan Hutan Tanaman di Indonesia
Abstrak: Indonesia is one of the countries in the world which has tropical forests. In the context of size, Indonesia has 6% of the world's tropical forests (1046 million hectares) and 13% of all the world commercial timber’s supplies. Seeing these various potential of natural resources, the need for utilizing forest products for either timber or non timber forest in an optimal and fair way for public welfare while maintaining its sustainability. One way to do this is by the utilization of forest plantations. Hence, it is necessary to develop a geographic information system that is useful for disseminating information related to the utilization of forest plantations in Indonesia. Kusumasari (2009) and Muhani (2010) have previously developed an application concerning geographical information systems. These studies has provided a visual and interactive information. However, both studies are limited in Bogor area and the input data are hard-code into system, making it difficult to modify new data. Therefore, in this study, a system was developed using ASP.NET as its framework, supporting database systems which separates the data into the database to make it easier to manipulate the data. This study was developed by using spatial data obtained from the Directorate General of Forest Production Development (FDP) and was presented visually in maps and was based on web to facilitate in information search process related to utilization of forest plantations in Indonesia. The main function of this system is to display the overlay of map data on Google Maps, to provide zoom function, and to show the attributes of or the description from an interactive map. This system also provides a search function based on type of report, location, type of crop and type of forest utilization

Judul: Penerapan sistem informasi geografis untuk mendukung kegiatan perencanaan dan pengelolaan hutan pendidikan Gunung Walat Sukabumi, Jawa Barat
Abstrak: Sejak tahun 1961 hutan Gunung Walat ditetapkan sebagai hutan pendidikan. Pengelolaannya oleh pemerintah diserahkan kepada Institut Pertanian Bogor yang secara langsung dikelola oleh Fakultas Kehutanan. Sejak saat itu hutan tersebut mempunyai fungsi yang lebih luas lagi yaitu selain fungsi lindung dan fungsi sosial ekonomi juga sebagai sarana pelaksanaan Tridharma Perguruan Tinggi bagi IPB. Untuk itu diperlukan suatu sistem yang cepat dan tepat untuk mendukung kegiatan perencanaan dan pengelolaannya. Salah satu jenis teknologi yang mempunyai kemampuan menghimpun dan menganalisa data geografis untuk mendukung kegiatan perencanaan pengelolaan hutan yang sudah dikenal dan diakui kehandalannya adalah dengan menggunakan Sistem Informasi Geografis. Penelitian ini bertujuan membuat pangkalan data daerah Hutan Pendidikan Gunung Walat dengan sistem informasi geografis dan membuat peta penetapan fungsi hutan. Hasil penelitian ini diharapkan dapat digunakan sebagai sumber informasi di dalam perencanaan Hutan Pendidikan Gunung Walat. Bahan dan alat yang digunakan pada penelitian ini adalah kertas, komputer PC beserta kelengkapannya dengan perangkat lunak ARC/INFO versi 3.4D plus dan meja digitizer. Data yang digunakan adalah data sekunder yang mencakup data spasial dan data atribut (tabel). Data spasial yang digunakan adalah peta topografi skala 1:50.000 tahun 1962, peta klasifikasi tanah skala 1:10.000 tahun 1981, peta potensi skala 1:5.000 tahun 1983, peta tata batas skala 1:5.000 tahun 1990, peta administrasi Sub DAS Cicatih skala 1:50.000 tahun 1989. Sedangkan data atribut antara lain data curah hujan, data sosial ekonomi, dan data tabular lainnya....

Judul: Mud Crab’s (Scylla serrata Forskal 1775) Response to Different Decaying Level of Gold Snail (Pomacea canaliculata Lamarck 1822) Bait.
Abstrak: Mud crab is well known as omnivorous-vigorous-voracious-opportunistic-scavenger. These intertidal animals applies mainly chemoreception in their predatory behaviour. It has been commonly assumed that non fresh gold snail bait is better than fresh bait in stimulating the mud crab. This research's aim is to analyze mud crab response to different decaying level of gold snail bait. Their response were observed as time required to touch the bait and pattern and direction of the mud crab in approaching the baits. The different decaying level of gold snail baits were shown on Total Volatile Base Nitrogen (TVBN) as 16.3 mg/100g (0 day); 534.1 mg/100g (3 days); and 887.4 mg/100g (6 days). The research was conducted from July 2009 until February 2011. The TVBN test for gold snail baits were conducted at Laboratory of BBPPHP Jakarta. The experiment was conducted in Pemalang. The result showed that the average period of mud crabs to touch the baits were 52.14 minutes; 61.57 minutes and 52.57 minutes. Anova test concluded no sufficient evidence of significant effect of TVBN content of gold snail bait on mud crab’s feeding behaviour. Movement pattern B, i.e. left and right deviation followed by straight forward movement to the bait, was commonly exhibited by the crabs. Consequences of time period required by the mud crab to approach the bait on fishing operation is discussed.
