Judul: Analisis Usahatani penangkaran benih padi dan padi konsumsi (Studi kasus di Desa Gunung Sari Kecamatan Pamijahan Kabupaten Bogor).
Abstrak: The Gunung Sari village is one of village located in the district Pamijahan is one of the centers of rice seed in Bogor regency each season seed paddy did not continue as the other districts are not doing the rice seed each season. Sari was a mountain village in terms of the topography of the land suitable for the cultivation of rice and rice seed. Sub Pamijahan experienced production is not conformity with the sales, unsold seed presence in the District Pamijahan will cause farmers' income breeders become smaller because the price at the farmers received seeds and rice farmers will be higher consumption of rice farmers seeds so farmers are so breeders will tend moved back into the consumption of rice farmers. The results obtained seed farming more profitable with the consumption of rice farming. Keywords: revenue, earnings and balance ratio receiving a cost

Judul: Analisis pendapatan petani Padi sawah di Desa Ciasihan Kecamatan Pamijahan Kabupaten Bogor
Abstrak: Rice production in Indonesia is getting decreased due to the presence of land conversion to non-agricultural sector. One area of West Java that having decline of crop land area is Bogor District. Production decrease of 7.54% from 2010 is caused by the reduced of crop land area that reaches 6 183 ha from 2010 to 2011. Increasing rice productivity isn’t always able to increase the amount of milled rice production if it is followed by a decrease in crop land area. The objectives of this research are to identify performance of rice farmers and analyze the income of rice farming in the Ciasihan Village. The research results indicate that rice farming is still viable seen from the amount of income, is Rp 5.545.169/season. The value of the ratio R / C of rice farming in the ciasihan village is 1.33. Therefore, to increase the income of farmers, the government can provide training and counseling, supporting equipment,and facilities for meetings.

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.
