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: 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: Pembuatan Produk Stik Aroma Diffuser dan Minyak Gosok Aromaterapi dari Hasil Fraksinasi dan Permunian Minyak Sereh Wangi
Abstrak: Rhodinol merupakan senyawa monoterpenoid yang terbentuk dari campuran Sitronelol dan geraniol dari hasil fraksinasi minyak sereh wangi yang berpotensi untuk dikembangkan dalam bidang aromaterapi. Namun, potensi pengembangan tersebut dibatasi oleh sedikitnya pengetahuan tentang penggunaan bahan aromaterapi tersebut. Rhodinol dikenal memiliki wangi yang “lembut" sehingga bila dijadikan bahan pewangi menjadi bahan ‘top note’ pada pewangi yang memberikan kesan pertama. Salah satu upaya untuk memperluas aplikasi rhodinol adalah menformulasikan produk pewangi yang menggunakan bahan tersebut yaitu stik aroma diffuser dan minyak gosok aromaterapi. Stik aroma diffuser dibuat menggunakan bahan stik rotan dan stik bambu berdiameter 1 mm dan 2 mm, panjang stik 20 cm serta menggunakan base polypropylene glycol dengan formulasi minyak nilam 40%, melati 20%, rhodinol 40% atau rhodinol 20% dan mint 20%. Produk minyak gosok aromaterapi diformulasikan dengan base campuran minyak kelapa dan zaitun, dengan bahan aromaterapinya adalah kayu putih, cengkeh, rhodinol, mint, lemon, menthol dan champor. Uji untuk produk stik aroma diffuser ini adalah uji hedonik dengan 30 panelis terlatih serta uji ketahanan aroma selama sekitar 7 hari. Untuk uji yang dilakukan pada minyak gosok aromaterapi adalah uji hedonik dengan 30 panelis terlatih. Produk stik aroma diffuser yang menggunakan rhodinol 20% dan mint 20% yang memiliki respon kesukaan terbaik dan yang menggunakan bahan stik rotan dengan diameter 1 mm memiliki ketahanan lebih lama dibandingkan dengan bahan stik bambu berukuran diameter 1 mm dan 2 mm serta bahan stik rotan dengan diameter 2 mm. Produk minyak gosok aromaterapi memiliki respon terbaik pada formulasi minyak kelapa 31%, minyak zaitun 31%, kayu putih 5%, rhodinol 5%, mint 5%, lemon 5%, menthol 15% dan champor 3%. Aroma mint dan rhodinol pada stik aroma diffuser lebih disukai daripada yang berbahan rhodinol saja dan aroma diffuser yang menggunakan bahan rotan menghasilkan ketahanan 10% lebih lama dari bambu. Produk minyak gosok yang terpilih mendapat penilaian tertinggi karena penilaian panelis menjadi lebih subjektif pada tingkat kehangatan dan respon produk keseluruhan, tingkat kehangatan dilihat dari komposisi menthol yang pada nilai 15% memiliki nilai kesukaan tertinggi.
