Judul: Web-based GIS cambodia natural conservation areas information system (Case study: Phnom Prich, Mondulkiri Province, Cambodia)
Abstrak: Internet has become a competent technology for data communication due to distributing technology of the web servers. The data and maps reach to the thin clients with the minimum system requirements at end user and with the click of a button. Such technology has not only popularized the whole world but has moved scientific body to one step up. Geographers and planners, who use map and related information traditionally to plan and manage, have found internet technology of much use since it reduces the cost of data management and information distribution to mass usages. With the advent of GIS and internet technologies, the conventional intricacies to get solutions in time and position have been improved. Users can combine data and information accessed over the intranet/internet with the local data for display, query and analysis. The major goal of this project was to implement a Web-Based GIS that enhances the information system of natural conservation areas. To accomplish the above-stated goal, the project has four objectives such as: developing a geographic information system with web basis (WebGIS) for Cambodia Natural Conservation Areas; called as CNCAIS – Cambodia Natural Conservation Areas Information System, interfaced with GIS for the analysis and visualization of spatial data in vector/image format, permits the combination of GIS data with tabular data, and allow the users to access the databases via standard internet/intranet explorer such as Microsoft Internet Explorer, Opera, or Netscape Navigator. Web-Based GIS CNCAIS performance has been tested by sample end user and the representation of government officer (Ministry of Environment). This process was done to see what are the comments from the users after seeing and using this system. Generally, the users understand how to use web application in order to get the information as they needed thorough intranet since on the web application is provided with common navigation menu; just like when they open other websites on the internet. To cover this problem, Web-Based GIS Cambodia Natural Conservation Areas Information System will be equipped with help tools which consists the manual guide to help the users. Through this system, the users will be able to query and locate plots, roads, national park and other geographic features of interest, as well as view information about them, and create maps on-screen or to print. The users can turn map layers “on” or “off,” depending upon user needs. Also, some of these layers are scale-dependent and can only be viewed when you are zoomed in far enough.

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: Pengaruh perlakuan suhu dan lama pemanasan terhadap kerusakan margarin
Abstrak: Konsumen sering menggunakan margarin sebagai media pemanas dalam mengolah bahan pangan karena akan memberikan aroma dan cita rasa yang lebih baik pada bahan pangan jika dibandingkan dengan minyak goreng. Penggunaan margarin pada suhu yang tinggi akan menyebabkan terjadinya kerusakan terutama pada kandungan asam lemak tidak jenuh dan pewarna B karoten yang ditambahkan. Hal ini terjadi karena asam lemak tidak jenuh dan B-karoten sangat tidak stabil dengan adanya panas. Blueband margarin dan Simas margarin dipanaskan pada kisaran suhu dari 120°C sampai 220°C selama 30 menit dan 60 menit. Setelah pemanasan akan dilihat pengaruh waktu dan suhu pemanasan tersebut terhadap kerusakan margarin yang digunakan. Blueband margarin sebelum pemanasan mempunyai kandungan bilangan peroksida 7.08 mg O₂/100 g sedangkan Simas margarin 3.11 mg O₂/100 g. Suhu pemanasan 160°C selama 60 menit akan menghasilkan kandungan peroksida tertinggi pada Blueband margarin yaitu sebesar 23.93 mg O2 /100 g. Pemanasan pada suhu yang lebih tinggi yaitu 180°C selama 30 menit akan menurunkan kandungan bilangan peroksida Blueband margarin menjadi 17.83 mg O₂/100 g. Penurunan kandungan peroksida akan diikuti dengan terbentuknya komponen polimer sehingga fraksi polimer (%) akan segera meningkat. Fraksi polimer pada Blueband margarin sebelum pemanasan sebesar 1.00% dan akan meningkat pada suhu pemanasan 160°C selama 30 menit menjadi 9.63%. Peningkatan fraksi NAF ini akan terus berlangsung dengan semakin tinggi dan lama waktu pemanasan. Kandungan peroksida tertinggi pada Simas margarin terjadi setelah pemanasan pada suhu 140°C selama 60 menit menjadi 19.97 mg O₂/100 g. Jika pemanasan...
