Abstrak: Satay milkfish is one of the processed milk fish which is a typical food of Banten. Average satay milkfish done in small and medium scale enterprises into the home industry. The purpose of this research is to analyze the profitability of the satay milkfish business and to analyze value -added business satay milkfish for every kind of business. This research used survey method. The location of the research is taken with purposive method with selecting Ratu Toety business and Hj. Mariyam business. The results showed that the two businesses are able to generate profits. The business Ratu Toety profitability ratios of 29.1 percent greater than the business Hj. Mariyam 27.8 percent. The analysis showed the added value of two businesses generate value added is not much different. Value-added businesses Ratu Toety of Rp 39 467.00 or by 41.8 percent, while business Mariyam Hj Rp 39 172.00 or 41.5 percent.

Judul: Profitability Analysis and Value Added of Catfish Processing at Mina Sejahtera Processing Group Fish.
Abstrak: Ikan lele adalah salah satu jenis ikan budidaya yang memiliki produksi tertinggi di Kabupaten Bogor. Produksi yang terus mengalami peningkatan merupakan salah satu bentuk pencapaian dari visi Kementerian Kelautan dan Perikanan dalam meningkatkan produksi perikanan Indonesia. Tingginya produksi ikan lele membuat banyak pengusaha yang mengolah ikan lele. Tujuan dari penelitian ini adalah menganalisis profitabilitas usaha dan nilai tambah pada produk olahan ikan lele menjadi abon dan dendeng yang dilakukan oleh Poklahkan Mina Sejahtera. Alat analisis yang digunakan adalah metode Hayami, MIR, MOS, dan BEP. Hasil analisis menunjukkan bahwa Poklahkan Mina Sejahtera mampu menghasilkan laba pada kedua produk. Produk olahan abon memiliki nilai profitabilitas sebesar 39.69 persen dan produk olahan dendeng sebesar 35.52 persen. Produk olahan abon memiliki nilai tambah sebesar Rp25 051.31 dan produk olahan dendeng sebesar Rp20 181.34 . Oleh karena itu, produk olahan abon memiliki nilai tambah dan profitabilitas yang lebih tinggi dibandingkan dengan produk olahan dendeng

Judul: The Exploration of Discrete Logarithm over Finite Field GF(3m)
Abstrak: The security of many public~key algorithms is based on the problem of finding discrete logarithms. The generalized discrete logarithm problem is the following: given a finite cyclic group G of order n, a generator a of G, and an element fl E G, find the integer x, 0 ~ x ~ n - 1, such that 0: = fl. Algorithm for discrete logarithm problem focused on Menezes et al. (1997) that consist of exhaustive search algorithm, the baby-step giant-step algorithm, Pollard's rho algorithm, Pohlig-Hellman algorithm, and index-calculus algorithm. These algorithms are explorated to be used in discrete logarithm problem over finite field GF(3m ). The exploration also produces some algorithms, i.e. naif negative algorithm, baby-step mother-step algorithm, baby-step mother free-step algorithm, and baby-step free-step algorithm. All algorithms implemented using Maple 11. The Pohlig-Hellman and baby-step giant-step algorithms are efficient enough to be used in discrete logarithm problem over finite field GF(3m ) for m < 20.
