Judul: Develoment of a spatial database management system using object-relation database and web technology
Abstrak: The increasing need of spatial data and the complexity of GIS analysis, has affected the importance of the availability GIS data as well as the method to provide the GIS data become a great challenge to meet the user needs. The utilization of Information Technology, especially Internet, has affected to the effectiveness of GIS data sharing, dissemination and how the data accessed and manipulated. Most of spatial database management manages the GIS data separate descriptive data management from geospatial data management (hybrid approach), which sometimes implies difficulties in data management such as querying, recovery, optimization and geometric computations. The objectives of this research are to; [1] develop a system of spatial database management using object-relational database and web technology, [2] develop a system and tools to store, access, retrieve and use the integrated spatial database. To avoid the weakness of hybrid approach, an integrated approach spatial database management system was used in this research. By taking the strength of Object Relational Database in managing complex process and complex querying, a web based application has been built to provide the front-end application to access GIS data through Internet/Intranet. The application system has some functionality such as: spatial database and meta- database management, spatial data and metadata catalog and presentation, and user management. By using this application system, both of data type can be managed in integrated approach, which means that all data stored within the same database management system, and keep the close relation between spatial data and attribute data or metadata. This approach is much better than hybrid approach in spatial database management system. Currently, the application system only handle shapefile data format. Even the map file and legend can generate dynamically (on the fly) by the application, but it is limited for geomorphology theme only. It is recommended to improve these capabilities to accept more different data format and improve the data sharing function (clearinghouse) by applying Z.39 protocol...dst

Judul: Penerapan Database Management System (DBMS) Non-Relasional MongoDB dalam Pengembangan Portal Katalog Data Spasial
Abstrak: Most of applications nowadays use database as a primary storage, there is even no exception for web-based Geographic Information System (GIS). Nonrelational database is more appropriate to be used in webGIS for its ability to process unstructured and semi structured data with high availability and scalability level efficiently. There are several Database Mangement System (DBMS) handle non-relational database. This study aims to build a system using MongoDB for its ability to store data into document form. Furthermore, Opengeo used in this study to display attribute data stored at MongoDB. This system able to display attribute data taken from Twitter Application Programming Interface (API) that user can view available information

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...
