Judul: Stock Status of Mackerel (Rastrelliger faughni Matsui, 1967) in the Sunda Strait
Abstrak: Ikan kembung (Rastrelliger faughni Matsui, 1967) merupakan salah satu jenis ikan pelagis yang memiliki nilai ekonomis penting, sehingga termasuk salah satu target penangkapan nelayan di Perairan Selat Sunda, Banten. Tujuan dari penelitian ini adalah menentukan status stok sumberdaya ikan kembung di Perairan Selat Sunda berdasarkan ikan yang didaratkan di Pelabuhan Perikanan Pantai (PPP) Labuan Banten. Penelitian ini dilakukan pada periode Juni hingga Oktober 2014. Analisis yang dilakukan meliputi analisis nisbah kelamin, hubungan panjang dan bobot, tingkat kematangan gonad, fekunditas, sebaran kelompok umur, mortalitas, laju eksploitasi, dan model produksi surplus. Hasil yang diperoleh menunjukkan bahwa pola pertumbuhan ikan kembung betina maupun jantan adalah allometrik positif. Laju eksploitasi ikan kembung betina dan jantan telah mengalami tangkap lebih. Hasil tangkapan maksimum lestari dan upaya optimum sebesar 422 ton per tahun dan 758 trip per tahun.

Judul: Status stok sumberdaya ikan kembung lelaki (Rastrelliger kanagurta, Cuvier 1817) di Perairan Selat Sunda
Abstrak: Indian Mackerel (Rastrelliger kanagurta) is one of small pelagic fish that has a economic value. The purpose of this research was to determine the status of stocks and suggest management of Indian Mackerel (Rastrelliger kanagurta) and sustainability in the Sunda Strait based on catch data by fisherman landed on PPP Labuan, Banten. The research was conducted from May 2014 till October 2014. Total fishes that were caught is 480 individuals. The growth pattern of female Indian Mackerel is isometric and negative allometric for male Indian Mackerel. The amount of Maximum Sustainable Yield (MSY) and optimum efforts, 571 tonnes per year and the 1 010 trip per year. Exploitation rate was exceeded the optimum level is 0.5, implied that the Indian Mackerel fishery of Sunda Strait has been overfished. Management process that can be conducted is to regulate the fishing effort, fishing season, and mesh size.

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.
