Judul: Pengembangan Sistem Pengiriman Hasil Suara pada E-Voting Two Central Facilities yang Dimodifikasi
Abstrak: Election system in Indonesia still uses conventional method that has many disadvantages such as: slow voting result's calculation, slow voting result's transmission to the central committee, and large amount of human resources. E-voting is expected to solve the problems and the most secure election protocol that meets the standards of secure voting requirements according to Schneier (1996) is Two Central Facilities Protocol. The goal of this research is developing voting result transmission system based on modified Two Central Facilities Protocol designed by Kusumah (2012), analyzing the developed transmission system's running time, and determining the influence of cryptographic algorithm usage on developed transmission system's running time. Through this research, we developed a voting result transmission system and found that cryptographic algorithm usage on this system contributes 22.58% of the total system running time which is relatively low. We recommend further research regarding analyzing other factors beside cryptographic algorithm usage and database security implementation on voting result transmisson system.

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: Aspek kehidupan dan reproduksi pada lumba-lumba
Abstrak: Lumba-lumba merupakan mammalia yang hidup di laut dan sebagian hidup di beberapa perairan air tawar. Hewan ini mempunyai bentuk tubuh yang streamline, moncong seperti paruh serta mempunyai gigi kurang lebih 200 buah. Tubuh lumba-lumba dilapisi oleh spermaceti yang terdiri dari lapisan minyak. Hewan yang sering terlihat di gelanggang-gelanggang samudra ini mempunyai ekor horizontal dan panjang tubuhnya berkisar 1,1 meter sampai 9 meter (Yablokov, 1974). Bia- sanya jantan lebih besar daripada yang betina. Di dalam klasifikasinya lumba-lumba termasuk dalam kelas mammalia, ordo Cetacea dan subordo Odontoceti. Di seluruh perairan dunia, terdapat banyak sekali spesies lumba-lumba, yang keseluruhannya termasuk ke dalam kelompok famili Delphinidae yang terdiri atas 19 genus ya- itu : Steno, Sotalia, Stenella, Delphinus, Lissodelphis, Orchinus, Lagenodelphis, Tursiops, Grampus, Lagenorhynchus Orcaella, Cephalorhynchus, Peponocephala, Feresa, Pseu- dorca, Globicephala, Phocoena, Neophocoena, dan yang terakhir Phoconoides (Yablokov, 1974). Tiga genus yang terakhir tidak termasuk lumba-lumba. Selain famili tersebut di atas, terdapat pula lumba- lumba yang hidup di perairan air tawar, yaitu dari famili Platanistidae (Cousteau, J.Y. , 1975). Makanan utama lumba-lumba berupa ikan (tuna, cumi-cu- mi, dan lain-lain), mollusca, cephalopoda dan crustacea. Dalam mencari makanannya, lumba-lumba bermigrasi secara teratur. Mereka menghabiskan musim panas di daerah kutub, kemudian bermigrasi ke daerah selatan selama musim dingin. Habitat lumba-lumba yang mutlak adalah air, baik air asin maupun air tawar. Mereka tidak dapat meninggalkan air, meskipun menurut asal-usulnya lumba-lumba merupakan mammalia darat (Coffey, D.J. 1977). Menurut Yablokov (1974) lumba-lumba betina memiliki sepasang ovarium yang rata/licin yang terdapat dalam ova- rian sac. Pada vagina beberapa spesies lumba-lumba terda- pat sumbat vagina/plug..dst
