Judul: Hubungan kondisi terumbu karang dengan keberadaan ikan Chaetodontidae di perairan Pulau Abang, Batam:
Abstrak: Karang dimanfaatkan tidak saja sebagai makanan bagi ikan Chaetodontidae, tetapi juga sebagai tempat tinggal (Harmelin-Vivien & Bouchan-Navaro 1983). Bell & Galzin (1984), Sano et al. (1984), Adrim & Hutomo (1989), Bouchon- Navm dan Bouchon (1989), Edrus & Syam (1998), Zekeria & Videler (2000) menuniukkan bahwa keanekamzarnan dan kelimuahan ikan famili Chaetodontidae meninhat dengan meningkagya tutupan karkg hidup. Penelitian ini penting dilakukan untuk daoat mengetahui mruhan kondisi terumbu karang secara cepat, tepat dan mudah. ^ ~ d a ~t&u j k d ari penelitian ini adalah m~ndeskripsiican kondisi terumbu karang dan ikan Chaetodontidae, menganalisa hubungan antara kondisi terumbu karang dengan ikan Chaetodontidae sebagai dasar menentukan rekomendasi pengelolaan terumbu karang berbasis ekologi. Penelitian dilakukan di perairan Pulau Abang Kecil dan sekitamya pa& Kelurahan Pulau Abang, Kecamatan Galang, Kota Batam. Penelitian ini berlangsung selama 4 (empat) bulan yaitu sejak bulan Mei-Agustus 2009. Pengambilan data terumbu karang dilakukan dengan metode LIT. Pengambilan data ikan Chaetodontidae dilakukan dengan metode UVS. Pengambilan data parameter lingkungan dengan dilakukan &ara in-situ. Analisa isi &rut atau jenis makanan ikan Chaetodontidae dilakukan di Laboratorium EkoBiologi De.pa rtemen Manajemen Sumberdaya Perairan (MSP).

Judul: Keterkaitan antara terumbu karang dengan ikan chaetodontidae: implikasi untuk pengelolaan
Abstrak: This study was aimed to explore the relationship between fish Chaetodontidae with the percentage of live coral cover as pre reguisite for appropriate management. The research was conducted Sidodadi waters and Tegal island Province of Lampung in during April to Juni 2010 at 6 stations. Data for coral reef was collected using visual census fish and line intercept transect method which placed parallel to the coastline. The results recorded 115 species of fish Chaetodontidae, representing 2 Genera, namely Chaetdon (91 species), and Chelmon (24 species). The variety of the diversity index, could be an indicator of the quality of coral reefs which ranging from 0,28 to 1,38 and the coral cover between 47.94% to 67.14%. The correlation between the percentage of live coral and fish Chaetodontidae were positive, where the coefficient of determinant (r) of each species more than 80,20 %. Analysis of fish feeding habit Chaetodontidae favorite show that the coral life is very high, in additional all species analyzed zooxanthelae presence of very high compared with plankton, detritus, and algae plankton. Therefore the fish Chaetodontidae highly dependent on living coral as its main food.

Judul: Simulasi Protokol Autentikasi Pelanggan pada Voice Privacy
Abstrak: Existing design of the telephone public network is susceptible to eavesdropping on its voice stream. Consequently, any wire taper can listen to supposedly private conversation. In order to prevent such eavesdropping, we propose a protocols and its implementation for end-to-end voice privacy authenticate as a service available for interested subscribers. Our protocols consist of customer enrollment system, customer authentication system and simulation voice privacy. Protocols that we made are adaptation from Sharif and Wijekesera journal with the title Providing Voice Privacy as a Service over the Public Telephone Network. The result of the process shows how the customer enrolls and how the system process the password, how the system authenticate customer simulate voice privacy.
