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: 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: 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...
