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: Analysis and Development of Tabulation System Two Based on Central Facilities Protocol.
Abstrak: An Elections is a form of democracy by which a society appreciate freedom to vote. In many countries such as Indonesia elections are still held conventionally. The Elections that Indonesia has just held to choose a leaders of state and nation are still requiring a very large cost and other strategic resources such as human resources, place, and time. One solution that can reduce this problem is by holding online voting. However, as the conventional election, this online voting system cannot be completely free from all forms of cheating threats that may occur. Therefore, the system which will be built should fulfill secure voting requirements in order to ensure every threats can be prevented. One protocol that can fulfill most secure voting requirements and have very good security level is the Two Central Facilities Protocol. This protocol has two facilities, one of it is the Central Tabulating Facilities (CTF). CTF is the central tabulation of electoral votes which play a very important role in elections. CTF is also responsible for publishing the election results to the audience. A Good and interesting publication by CTF may also attract attention and help the audiences to understand the published message easier.

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%).
