Judul: The Development of Web Based Geographic Information System for Publication of Plantation Commodities (Case Study ofLombok Barat Plantation)
Abstrak: Plantation crops commonly found in Lombok Barat are coconut, coffee, clove, cashew nut. The plantation sub sector contributed towards the agricultural sector about 18.26 % in 2000, while coconut is the main product of plantation commodities about 76.11 % beside from coffee about 8.06 % and cashew nut about 5.67 %. Others commodities only contributed below 4 % and the smallest one is the cotton about 0.001 %. In this regency plantation commodities are traditionally used for food or livestock feed, but potentially introduce for use ii;i a wide range of industrial applications. The objective of this research is to design the information system for publication of the plantation commodities. The development of a web-based system by integrating GIS and RDBMS could serve two crucial purposes, where internet based geographical data services involve management of spatial and non­spatial (attribute) data. The Internet and Web-based GIS is an effective medium for publication of spatial data. Web-based GIS is not a single technology, there are many component combined to build web based GIS, such as software, hardware. The system development lifecycle (SDLC) is an application of the systems approach to the development of a computer-based information system or subsystem. SDLC consist of a series of task that closely follow the step of the system approach. The system life cycle consist of five phases. The first four (planning, analysis, design, and implementation) are devoted to development. The fifth phase is devoted to use. The result of this research showed the spatial information and non spatial information by using web based information system. Database as one of the development phase designed to support spatial and non spatial information, which are divided into three steps: conceptual design, logical design and physical design. There are some spatial information displayed in the web such as five kinds of plantation areas (Coffee, coconut, cashew nut, tobacco and vanilla) and infrastructures (roads and markets). Plantation areas on Lombok Barat regency founded in almost all of districts, where southern part of regency especially Bayan and Gangga districts founded wide areas for coffee and coconut plantation. Traditional market located on each districts and Narmada districts located six traditional market. Non spatial data resulted from system such as production of plantation and other information about plantation commodities. Web based Geographic Information System (GIS) will bring new approach for querying information and display production area of the plantation commodities which are interactively communicate with user to query and to display map.

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: Penentuan energi aktivasi ion untuk melewati membran teflon pada berbagai larutan elektrolit
Abstrak: Kaseno (1999) menyatakan bahwa dalam teknologi pemisahan, membran adalah bahan yang dapat memisahkan dua komponen dengan cara yang spesifik yaitu menahan atau melewatkan salah satu komponen lebih cepat dari komponen lainnya. Kemampuan pemisahan yang dimiliki oleh membran untuk melewatkan suatu senyawa kimia atau molekul diakibatkan oleh adanya perbedaan sifat fisika atau kimia antara membran dengan senyawa kimia.
