Judul: Peningkatan Produktivitas melalui Modifikasi Peralatan dan Metode Produksi di PT. Buana Segar Lestari, Tangerang Selatan.
Abstrak: Manufacturing plant affects many aspects of food production. One of those important aspects it affects is productivity. Low productivity often results in low yield, huge loss, and undoubtedly reduced revenue. Due to the importance of those impacts, any problems affecting productivity should be addressed immediately with appropriate measures. In PT. Buana Segar Lestari, these productivity problems include inefficient processing technology, bottleneck processes, and non-value-adding production process. In order to handle those problems, modification of manufacturing equipments and methods are necessary. The modifications are focused on improving filling efficiency by modification of filling equipment and reducing process cycle time by eliminating bottleneck processes. This internship assess the productivity of PT. Buana Segar Lestari before and after modifications in four aspects: production efficiency, length of process steps, material flow analysis, and line capacity efficiency. After modification, production efficiency increase by 8.54 percent, while 2 bottleneck processes are successfully eliminated. Amount of products waiting in bottleneck process is also reduced from 3372 bottles to only 1508 bottles, while the maximum capacity for 8 hours production increase from 4032 bottles to 7694 bottles. Through those improvement, the line capacity efficiency also increase from 42,70% to 64,60%. Thus, the modifications to manufacturing equipment and methods are proven to be able to increase productivity in PT. Buana Segar Lestari, South Tangerang.

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.
