Judul: Perkembangan Daya Dukung Sumberdaya Ikan di Indonesia Tahun 2005-2010
Abstrak: Indonesia mempunyai potensi sumber daya ikan untuk memenuhi pangan hewani. Penelitian ini untuk mempelajari tren sumber daya perikanan di Indonesia Tahun 2005-2010. Studi deskriptif. Jenis data yang dikumpulkan dan digunakan dalam penelitian ini adalah data sekunder data, terdiri dari data total produksi ikan, produksi ikan berdasarkan ekosistem dan cara produksi, produksi ikan yang didaratkan di pelabuhan, impor dan ekspor, jumlah dan laju pertumbuhan penduduk, penggunaan ikan, dan ketersediaan ikan pada tahun 2005-2010. Hasil ini menunjukkan bahwa laju pertumbuhan produksi ikan rata-rata sebesar 9%. Total produksi ikan dipengaruhi oleh produksi dan penangkapan ikan budidaya. Produksi perikanan budidaya rata-rata meningkat 19,19%, sedangkan produksi penangkapan rata-rata meningkat 2,63%. Tingkat produksi penangkapan di laut (2,62%) lebih baik dibandingkan lainnya (-2,31%). Produksi perikanan budidaya di laut lebih besar dibandingkan yang lain (2,01 juta ton) (tambak, kolam, keramba, jaring apung, sawah). Tingkat pertumbuhan ekspor dan impor rata-rata sebesar 4% dan 13%. Sumber daya ikan di Indonesia mempunyai potensi daya dukung kebutuhan protein. Tingkat rata-rata protein kontribusi sumber daya ikan yang tersedia > 100%.

Judul: Analisis keragaan konsumsi ikan di Indonesia tahun 2005 - 2011
Abstrak: The objective of this study was to analyze fish consumption in Indonesia 2005–2011. The design of this study was the descriptive study. Data used in this study was secondary data based on national social and economic survey (SUSENAS). The study showed average national actual fish consumption 26,04 kg/capita/year, average rural actual fish consumption 25,69 kg/capita/year and average urban actual fish consumption 26,51 kg/capita/year. Average growth rate of national fish consumption is 0,05% per year. Average growth rate of rural fish consumption is -0,05% per year. Average growth rate of urban fish consumption is 0,37% per year. The group of fish that consumed the most is fresh fish (62%) and the less is cooked food (10%). Average national fresh fish consumption is 16,16 kg/capita/year. Average rural fresh fish consumption is 15,74 kg/capita/year. Average urban fresh fish consumption is 16,71 kg/capita/year. Fish consumption from prepared fish is higher in rural (32%) tahunan urban area. Average national prepared fish consumption is 7,25 kg/capita/year. Average rural prepared fish consumption is 8,30 kg/capita/year. Average urban prepared fish consumption is 6,39 kg/capita/year. Fish consumption from cooked food is higher in urban (14%) than rural area. Average national fish consumption from cooked food is 2,63 kg/capita/year. Average rural fish consumption from cooked food is 1,65 kg/capita/year. Average urban fish consumption from cooked food is 3,71 kg/capita/year. Low expenditure group consumed fish lower than high expenditure group. Ideal fish consumption is 32,7 kg/capita/ year or 12,9 gram protein/capita/day.The sufficiency of fish is projected 8,10 million tons at 2015.

Judul: Konstruksi Hukum Grup Kurva Eliptik Atas F3m
Abstrak: Elliptic curves upon F3m can be divided in two cases, i.e. supersingular and nonsupersingular case. Based on group laws on elliptic curves, a new arithmetic upon F3m can be formulated as an addition process of two random points on the curve. This addition process can then be applied to the ElGamal algorithm.
