Judul: The Analysis and Development of GUI and Voter-CLA Cryptography Protocol based on Two Central Facilities Protocol.
Abstrak: General election is a democratic party for each democracy country. Each country has rules in it. However, every country wants the general election surely implemented in a fair, equitable and confidential way. At the time of this community also wants the election results can be announced quickly. Along with technology development, some countries continue to try to create a system to conduct elections and made the system seeks to meet the rules. and can do calculations quickly and securely. Online voting is one of the solutions of the system. Online voting is trying to implement cryptography protocol. that made protocol seeks to make work flow of the election while the cryptography used to secure the data that is on a protocol. This research base on two central facilities protocol to implement online voting system. This research focuses on the protocol of voter-CLA, from the GUI for the voter, voter-CLA protocols and data storage access for the voter in the voting this online application.

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: 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...
