Judul: Disain Sistem Terintegrasi Berbasis Grid Untuk Analisis Sitiran Data Bibliografi
Abstrak: Analisis sitiran perlu dilakukan untuk mengevaluasi aktifitas ilmiah. Aktifitas ilmiah tergambar dari berbagai publikasi ilmiah. Karena itu, dibutuhkan sistem terintegrasi data bibliografi untuk memudahkan kegiatan analisis sitiran. Dalam penelitian ini, gambaran aktifitas ilmiah yang ingin diperoleh dari analisis sitiran ditunjukkan melalui formula entropi. Sebuah prototipe sistem untuk mengintegrasikan dua data bibliografi dari publikasi ilmiah telah dikembangkan dalam penelitian ini dengan memanfaatkan teknologi grid. Kedua data bibliografi tersebut disimpan dalam basis data yang berbeda, masing-masing dalam PostgreSQL dan MySQL. Prototipe sistem memanfaatkan perangkat lunak bantu Globus Toolkit dan OGSA-DAI serta diujicobakan menggunakan sistem operasi Fedora Core 4. Dalam penelitian ini, prototipe sistem yang dikembangkan mampu mendapatkan komponen-komponen variabel dari formula entropi, sehingga aktfitas analisis sitiran dapat dilakukan dengan mudah. Selain itu, diimplementasikan pula fasilitas keamanan dalam mengakses sumber data bibliografi untuk menjamin hanya pengguna terautentikasi yang dapat meminta layanan.

Judul: Disain sistem terintegrasi berbasis grid untuk Analisis sitiran data bibliografi
Abstrak: Citation analysis is necessary to evaluate development of scientific activities. These scientific activities are described in various scientific publications. Therefore, an integrated system in bibliography data is required for easier citation analysis. In this research, the development of scientific activities will be represented by entropy formulae. A grid-based system prototype has been developed to integrate two bibliography database systems, i.e. PostgreSQL and MySQL, respectively. The prototype makes use of Globus Toolkit and OGSA-DAI software, and is tested on Fedora Core 4 Linux platform. Our approach is promising, since the prototype is able to obtain variables constructing the entropy formulae. It shows that the citation analysis can be performed easier. A security mechanism in accessing the bibliography database systems is also adopted in the prototype which ensure that only the authenticated user can ask the citation analysis services.

Judul: Evaluation of Pasteurization Process Adequacy for Nata de coco in Polyethylene Plastic Bag
Abstrak: Nata de coco 2 kg in light syrup in polyethylene plastic bag is generally processed through pasteurization in water bath conveyor pasteurizer at temperature of 97-100oC for 20 minutes. The product is classified as a high acid food with pH less than of 4.0. The objective of this study was to evaluate pasteurization process adequacy of nata de coco based on its pasteurization value (Po). Pasteurization process adequacy was determined by comparing Po of the process to 6D80, 3D80 and 2D80. Microorganism targets were Lactobacillus sp., vegetative cell, mold, yeast and Byssoclamys fulva and Byssoclamy nivea, which were more heat resistant. Based on calculated Po, the pasteurization process was sufficient to inactivate 6D80 of vegetative cells, Byssoclamys fulva, and B. nivea and B coagulan, but was not sufficient to kill (6D80) B pasteurianum, B polymyxa, B. macerans and Alicyclobacillus acidoterrestris. The pasteurization process was sufficient to kill 3D80 and 2D80 of B pasteurianum, B polymyxa, B. macerans for initial temperature more than 80oC. The above pasteurization process was sufficient to kill 2D80 of Alicyclobacillus acidoterrestris. The initial temperature should be not less than 82oC to kill 3D80 of Alicyclobacillus acidoterrestris
