Judul: Web-based geographic information system for tourism (Case study of East Java Indonesia)
Abstrak: The objective of this research is to build Web-based GIS Information System that provides spatial and non-spatial tourism information via Internet environment. To reach the goal of this research, there are several activities that should be done. The first activity is design tourism database. This database has two types of data: non-spatial and spatial. Physically, Non-spatial data will be stored in Mysql DBMS. Spatial data will be stored in ESRI Shape format. The second activity is design Web-based GIS user interface to allow tourist to communicate with system. This activity is conducted by using HTML code, Java Script, and MacroMedia Flash. The last activity is to construct programming code to deal with tourism database. PHP programming language was used to access nonspatial data. MapServer and PhpMapScript was used to access spatial data. The result of this research is a Web-based GIS tourism information system, which has several functions for assisting tourist. Tourist not only can obtain information about tourism object but also can obtain the map of tourism object. The system also provides several functions for tourism facility such as: search hotel, flight schedule, train schedule, and tourism office

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: Katalis Zink Ferit Tersubstitusi Cu untuk Oksidasi Benzil Alkohol
Abstrak: Katalis berperan dalam menurunkan energi aktivasi. Katalis ZnFe2O4 dan ZnFe2O4 tersubstitusi Cu disintesis menggunakan metode kopresipitasi untuk digunakan dalam oksidasi benzil alkohol. Katalis dicirikan dengan spektrofotometer inframerah (FTIR) dan difraktometer sinar-X. Spektrum FTIR menunjukkan puncak serapan dari ikatan Zn-O dan Fe-O masing-masing pada rentang 559‒575 cm-1 dan 419‒447 cm-1. Difraktogram menunjukkan terbentuknya fase tunggal Zn0.6Cu0.4Fe2O4 pada katalis ZnFe2O4 tersubstitusi Cu 20%. Benzil alkohol dioksidasi dengan sistem refluks. Konversi benzil alkohol meningkat dengan meningkatnya suhu. Kadar benzaldehida yang dihasilkan dengan katalis ZnFe2O4 tersubstitusi Cu 20% lebih tinggi dibandingkan dengan katalis ZnFe2O4 yang tidak tersubstitusi dan yang tersubstitusi Cu 60 dan 80%. Hal tersebut menunjukkan bahwa katalis ZnFe2O4 tersubstitusi Cu 20% memiliki kinerja yang lebih baik dalam oksidasi benzil alkohol menjadi benzaldehida dengan kadar benzaldehida 8.763%.
