Judul: Analisis Profitabilitas Usaha dan Nilai Tambah Produk Olahan Ikan Bandeng pada Usaha Aneka Olahan Ikan Bandeng Mama's
Abstrak: Dikarenakan sifatnya yang mudah rusak (perishable), maka diperlukan pengolahan pada ikan agar kualitasnya tetap terjaga. Usaha Aneka Olahan Ikan Bandeng Mama’s adalah satu-satunya unit pengolahan fillet ikan bandeng yang terdaftar di Dinas Perikanan dan Kelautan Kabupaten Karawang. Penelitian ini bertujuan untuk menganalisis profitabilitas usaha dan menganalisis nilai tambah yang diperoleh pada produk pengolahan fillet ikan bandeng (nugget, bakso, dan kaki naga). Alat analisis yang digunakan dalam penelitian ini adalah Metode Hayami, MIR, MOS, dan BEP. Hasil analisis menunjukkan bahwa usaha pengolahan ikan bandeng tersebut mampu menghasilkan laba. Nilai profitabilitas produk nugget adalah sebesar 35.55 persen, bakso sebesar 31.38 persen, dan kaki naga sebesar 39.68 persen. Berdasarkan hasil analisis, nilai tambah pada nugget adalah sebesar Rp88 999.76 atau 71.20 persen, bakso sebesar Rp55 433.71 atau 61.59 persen, dan kaki naga sebesar Rp105 208.88 atau 75.15 persen. Hasil analisis profitabilitas dan nilai tambah menunjukkan bahwa kaki naga memiliki nilai profitabilitas dan nilai tambah tertinggi dibandingkan kedua produk lainnya.

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.
