Judul: Pembuatan Database dengan Pendekatan Event-based Spatiotemporal
Abstrak: The need of information about geographical changes is increasing. Therefore we need a concept for storing data to represent dynamic geographical phenomena especially the spatial object evolution. An Event-based Spatiotemporal approach is propose to overcome this problem (Wang 2005). The new definitions about version, process, and event allow us to describe how an object evolves during its evolution period. This research aims to implement an Event-based Spatiotemporal approach into Microsoft Access. As a result, we can get the information about an object evolution from spatiotemporal query such as show the location of Forest A at a given time and show the soil type of Forest A at a given time. These queries make analyze a spatial object easier.

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: Komposisi Asam Lemak dan Kolesterol Udang Ronggeng (Harpiosquilla raphidea) akibat Perebusan.
Abstrak: Udang merupakan makanan yang memiliki cita rasa yang khas dan lezat serta banyak diminati oleh masyarakat. Kandungan gizi yang khas pada udang salah satunya adalah asam lemak tak jenuh majemuk yaitu omega-3 yaitu eucosapentanoic acid (EPA) dan docosahexanoic acid (DHA), serta Omega-9 yaitu oleat. Oleh karena itu, sangat perlu untuk dilakukan penelitian mengenai gizi yang terkandung dalam udang ronggeng, terutama komposisi asam lemak dan kolesterolnya. Asam lemak memiliki fungsi yang penting bagi tubuh manusia, linoleat (Omega-6) dan linolenat (Omega-3) digunakan untuk menjaga bagian-bagian struktural dari membran sel, serta mempunyai peran penting dalam perkembangan otak. Asam lemak Omega-3 dapat menyembuhkan luka dan infeksi, trombosis, penyakit tulang atau persendian, asma, dan mencegah proses penuaan. Komponen utama kolesterol pada udang adalah high density lipoprotein (HDL) yang berfungsi mengurangi low density lipoprotein (LDL) dalam tubuh sehingga mampu mencegah penyakit arterosklerosis. Penelitian ini bertujuan untuk mengetahui pengaruh perebusan terhadap karakteristik, komposisi kimia dan profil asam lemak serta kandungan kolesterol daging udang ronggeng. Tahap awal penelitian ini adalah memperoleh informasi mengenai asal sampel, metode penangkapan, serta penanganan udang ronggeng. Tahap selanjutnya adalah mengkaji karakteristik udang ronggeng, yaitu ukuran, rendemen, cita rasa, komposisi kimia dan asam lemak serta kolesterol daging udang ronggeng. Udang ronggeng yang digunakan terdiri dari udang ronggeng segar dan udang ronggeng yang diberi perlakuan perebusan . Rendemen daging, cangkang, dan jeroan udang ronggeng segar berturutturut 41,27%, 54,15%, dan 4,59%, sedangkan rendemen udang rebus berturutturut yaitu 20,08%, 45,32%, 1,69% dan berat yang hilang (lost) sebesar 32,90%. Komposisi kimia yang meliputi kadar air, abu, lemak, dan protein daging udang ronggeng segar berturut-turut 76,55%; 1,27%; 1,54%; dan 20,42%; udang rebus, yaitu 74,09%; 1,39%; 22,46%; dan 0,83%. Asam lemak jenuh daging udang ronggeng yaitu miristat, palmitat, stearat dan didominasi oleh palmitat sebesar 29,23%. Total asam lemak jenuh daging udang ronggeng segar, yaitu 33,90% dan udang rebus yaitu 30,58% dari total asam lemak udang. Total asam lemak tak jenuh tunggal terdiri dari oleat yaitu pada daging udang ronggeng segar 20,61% dan udang rebus, yaitu 19,26%. Asam lemak tak jenuh majemuk udang ronggeng segar adalah linoleat, yaitu 14,97% dan linolenat, yaitu 7,69% dan udang rebus yaitu linoleat sebesar 8,9% dan linolenat sebesar 5,6%. Asam lemak tak jenuh mejemuk berantai panjang udang ronggeng segar terdiri dari EPA sebesar 7,49% dan DHA sebesar 7,17%, sedangkan EPA udang rebus, yaitu 7,17% dan DHA sebesar 0,95%. Total kolesterol udang ronggeng segar yaitu 115,33 mg/100 gram dan udang rebus 86,61 mg/100 gram.
