Judul: The Development of Voting Result Data Transfer to the Central Tabulating Facilities.
Abstrak: Advances in election voting process nowadays has triggered the application of virtualization technique in several countries. Most studies raised concern about Online Voting which provides cost saving and convinience. The voting system using virtual network technology aims to reduce considerable calculation time as well as necessary human resources. Despite this, Indonesia still performs voting during election manually. Therefore, this research is performed to study the application of small scale Online Voting at the Department of Computer Science, Bogor Agricultural University as well as studying its further possibility for applying this technique in larger scales. Considering the complexity in building a complete secure online election voting process, this research is focused only in developing a system to send vote from voter to Central Tabulating Facilities (CTF) by implementing a modified secure election protocol with Two Central Facilities. It is also conducted to implement earlier research recommendations to make the system more secure as well as how to integrate an election voting system from a single host into multiple hosts by using Java Web Start Technology.

Judul: The Analysis and Development of IPB Online Voting Centre Based on Two Central Facilities Protocol.
Abstrak: The election can be developed as an alternative to a conventional election that has many shortages, especially in security issues. Security of the virtual election can be assured if the election apply the most appropriate cryptographic protocol. This research carried out by four students, has developed virtual election based on two central facilities protocol. The difference with other protocol is that the new system implementing two institutions into two different servers. These institutions are Central Legitimization Agency (CLA) and Central Tabulating Facility (CTF). This system is also equipped with a secure sites since the central information take place during the election and registration facilities that make the voters registration process easily. This site is run safely through the secure socket layer to encrypt each data sent so the process of transferring file avoid from falsification of data.

Judul: Natural Pearlescent Pigment Dari Kristal Guanin Sisik Ikan Bandeng (Chanos Chanos)
Abstrak: Pearlescent pigment yang dikenal dengan nama pearl essence atau fish silver merupakan pigmen berwarna keperakan yang memiliki kenampakan seperti mutiara. Natural pearlescent pigment diperoleh dari sisik ikan dengan kandungan guanin 75-97%, dan kini mulai banyak digunakan pada industri personal care dan produk kosmetika. Penelitian ini bertujuan untuk menentukan teknologi ekstraksi natural pearlescent pigment dan karakteristik kualitatif kristal guanin pada sisik ikan bandeng (Chanos chanos). Perlakuan dalam penelitian ini meliputi ekstraksi menggunakan air deionisasi dengan sisik yang dibekukan terlebih dahulu, air deionisasi 10 οC, dimetil sulfoksida 15%, dan 25% (v/v). Hasil spektrum absorbansi UV-Vis menunjukkan kristal guanin merupakan pigmen berwarna putih berdasarkan serapan pada panjang gelombang 200-800 nm. Hasil terbaik diperoleh pada ekstraksi menggunakan air deionisasi dengan sisik beku nilai kristalinitas 68,4%, serapan gugus amina pada 3410 cm-1 dan gugus amida pada1681 cm-1, puncak intensitas 2θ pada sudut 27,7° yang menunjukan identitas dari kristal guanin anhidrat. Tingkat kandungan guanin sebesar 0,0455 ± 0,0033 g (0,46%).
