Judul: Pengembangan Sistem Autentikasi Voter pada Central Legitimization Agency Menggunakan Media Mifare Smart Card®
Abstrak: Cryptography becomes one of the important things in the development of electronic voting system. The voting system using internet network technology aims to reduce considerable calculation time as well as necessary human resources. Securing lines of communication between voting machines and servers is needed to communicate securely. The identity of the voters, which is used for authentication voting process is stored in Mifare smart card called identity card. Every identity card which contains unique identification and nomor induk kependudukan will be authenticated in Central Legitimization Agency server. Card identity is hashed with SHA-2 and encrypted with session key to assure that the integrity of data is not changed by others. Session key is distributed from CLA to voting machines which are encrypted with asymmetric RSA algorithm. Only voting machines can decrypt the ciphertext to get the session key as plaintext. The list of the voters who are allowed to vote is stored in the CLA database. The decrypted plaintext must be identical to one of the voters in the voters list, for the voter to be able to vote. Only one vote for each of the voters can be casted. If the time limit is reached, CLA will distribute the vote count to the Central Tabulating Facilities. Considering the complexity in building a complete secure online election voting process, this research is only focused developing a system to authenticate the voter identity in CLA from identity card which is stored in Mifare smart card.

Judul: Fingerprint as Voter Authentication for Development of E-Voting System Using Two Central Facilities Protocol.
Abstrak: Electronic voting (e-voting) is carrying out of balloting in a eletronic manner and can to utilizing information technology web-based in order that be able implementation election system in accordance with online in order to substitute election that be done conventionally (paper based) with a purpose to help problems solve at hand, such as elector of double, vote puschasing, the number of vote is illegal, etc. The e-voting system which developed using two central facilities protocol consist of three component that is voting machine as client for interaction with voter, central legitimization agency (CLA) as server voter authentication, and central tabulating facility (CTF) as server for result recapitulation voter vote count. Research in this thesis just focused to voter authentication process on voting machine toward database of voter that stored in CLA with using fingerprint biometric technology. Fingerprint biometric technology used for voter registration process, voter verification process, and voter authentication process who will doing election. Registration process for acquire voter fingerprint image database, verification process to be sure voter database can be verificated or not, and authentication process for voter authorization who can be permitted or not by system give of vote in election. In the voter authentication from this system, who voter can be permitted by system give of her/his vote will be directed to ballot page only voter who her/his fingerprint image recognizable by system. Whereas voter which her/his fingerprint image cannot recognized by system, so system will not direction to ballot page with the result that voter cannot give of her/his vote in election.

Judul: Penggunaan Celah Pelolosan Pada Bubu Tambun Terhadap Hasil Tangkapan Kerapu Koko di Pulau Panggang Kepulauan Seribu.
Abstrak: Bubu tambun merupakan salah satu alat tangkap yang dominan digunakan oleh nelayan di Pulau Panggang Kepulauan Seribu. Bubu ini dioperasikan di perairan karang pada kedalaman 0,5 3 meter. Hasil tangkapan bubu tambun adalah berbagai macam ikan karang, salah satunya adalah kerapu koko (Epinephelus quoyanus). Kerapu koko yang tertangkap pada bubu tambun mulai dari ukuran kecil sampai ukuran besar. Tertangkapnya kerapu koko yang berukuran kecil ternyata merugikan secara ekonomis dan biologis. Secara ekonomis, kerapu koko yang tidak sesuai ukuran pasar diolah menjadi ikan asin dan dijual dengan harga relatif murah yaitu sekitar Rp 12.000,00 per kg. Secara biologis, tertangkapnya kerapu koko yang masih kecil akan mengurangi laju recruitment ikan tersebut. Maka diperlukan mekanisme untuk meloloskan kerapu koko yang berukuran kecil. Salah satunya adalah dengan menggunakan celah pelolosan (escape gap). Tujuan dari penelitian ini adalah menentukan jumlah, ukuran, dan komposisi kerapu koko (Epinephelus quoyanus) yang tertangkap pada bubu yang menggunakan celah pelolosan (escape gap) dan bubu tanpa celah pelolosan (nonescape gap). Escape gap yang digunakan berbentuk lingkaran dengan diameter 4 cm. Metode penelitian yang digunakan adalah experimental fishing dengan 10 kali setting. Bubu tambun dipasang dengan sistem tunggal. Ikan dari famili Serranidae yang tertangkap pada bubu yang tidak menggunakan celah pelolosan (nonescape gap) diantaranya adalah kerapu koko (Ephinephelus quoyanus) sebanyak 31 ekor atau 4,78 % dari total hasil tangkapan pada bubu nonescape gap serta setara dengan 4,53 kg, kerapu hitam (Epinephelus ongus) 21 ekor atau 3,24 % dari total hasil tangkapan pada bubu nonescape gap serta setara dengan 2,9 kg, dan lain sebagainya. Adapun ikan dari famili Serranidae yang tertangkap pada bubu berescape gap diantaranya adalah kerapu koko (Ephinephelus quoyanus) sebanyak 20 ekor atau 4,46 % dari total hasil tangkapan pada bubu berescape gap serta setara dengan 3,68 kg, kerapu hitam (Epinephelus ongus) 16 ekor atau 3,57 % dari total hasil tangkapan pada bubu berescape gap serta setara dengan 2,97 kg, dan lain sebagainya. Ratarata panjang total, body girth, dan berat kerapu koko yang tertangkap pada bubu nonescape gap masingmasing adalah 20,55 cm; 13,76 cm; dan 146,03 gram. Adapun ratarata panjang total, body girth, dan berat kerapu koko yang tertangkap pada bubu escape gap masingmasing adalah 22,03 cm; 15,20 cm; dan 183,75 gram.
