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: Kajian Stok Ikan Kembung Lelaki Rastrelliger kanagurta (Cuvier, 1816) di Perairan Selat Sunda yang Didaratkan di PPP Labuan, Banten
Abstrak: Indian Mackerel (Rastrelliger kanagurta) is one of the small pelagic fish that has a significant economic value. It is abundant and caught dominantly in Sunda Strait. This study was aimed at examining the stasus of the Indian Mackerel (Rastrelliger kanagurta) stock, landed in PPP Labuan. The research was conducted in June 2013 to October 2013. Total fish caught were 1100 individuals. Length and weight relationships resulted in negatively allometric growth pattern. Analysis of resource potential of the Indian Mackerel was completed using Schaefer model, which was resulted in fMSY of 6078 trip per year and MSY of 1872 tonnes per year. Exploitation rate reached optimum level between 0.61-0.87. It is implied that the Indian Mackerel fishery of Sunda Strait landed in PPP Labuan has been overfished

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.
