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: Aplikasi informasi geografis dalam perencanaan pemanenan kayu
Abstrak: Pengelolaan hutan sudah lama didasarkan kepada data inventarisasi kuantitatif (volume kayu, riap, areal tegakan dan lain-lain). Proses pengelolaan data inventarisasi hutan dan pembuatan peta merupakan proses yang "melelahkan" dan memakan waktu yang lama serta hasilnya relatif kurang akurat. Karena lahan hutan dikelola semakin intensif dan peranan pemanfaatannya makin luas, semakin berkembang pula kebutuhan untuk memperoleh informasi yang lebih banyak dan lebih baik. Berhubung sebagian besar informasi ini menyangkut masalah hubungan antara loksi dan ruang, maka peta- peta selalu menempati peranan penting dalam pengelolaan lahan hutan. Peta-peta merupakan media penyimpan, penganalisa serta peragaan data masalah ruang. Saat ini aplikasi Sistem Informasi Geografis (SIG) di bidang kehutanan sudah sangat intensif. Penggunaan komputer untuk data spasial antara lain dengan menggunakan program Integrated Land and Watershed Management Information System (ILWIS). Sistem Informasi Geografis adalah suatu alat untuk memproses hal- hal yang bersangkuan dengan masalah ruang yang dapat digambarkan dalam bentuk peta-peta. Pada hakekatnya SIG dapat membantu dalam banyak hal yang berkaitan dengan pengelolaan dan perencanaan sumberdaya alam. Penelitian ini bertujuan untuk membuat perencanaan petak tebang dalam suatu model blok Rencana Karya Tahunan (RKT) yang dibuat dengan bantuan perangkat lunak Sistem Informasi Geografis. Sebagai acuan pada penelitian ini adalah Surat Keputusan Menteri Pertanian No. 837/Kpts/Um/11/1980 tentang Kriteria dan Tata Cara Penetapan Hutan Lindung dan Keputusan Presiden No. 32 tahun 1990 tentang Pengelolaan Kawasan Hutan Lindung, ...

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.
