Judul: Hubungan faktor reproduksi, asupan zat gizi dan aktivitas fisik dengan komposisi tubuh wanita pekerja berdasarkan status menopause
Abstrak: The purpose of this study was to examine the association of reproductive factors, nutrient intakes and physical activities with body composition of women worker in Bogor. This study used a cross-sectional design with 69 women workers aged 45-55 years old at Bogor Agricultural University as study participants. Descriptive analysis showed that mean of age at menarche, average of menstrual cycle, and average length of period of study participants were categorized normal. Energy and protein adequacy level were categorized as deficit. Physical activities level were categorized light activity with nutritional status were categorized obese. Almost participants had a high percentage body fat, central obesity, and android body shape. Correlation test showed that age (p=0.065) and the use of hormonal contraception (p=0.054) were positively associated with percentage body fat, meanwhile energy adequacy level (p=0.000), and protein adequacy level (p=0.000) were inversely related to percentage body fat. It might be conclude that age had more influence in increasing body fat, particularly in abdominal area, than menopausal status, nutrition intakes and physical activities in middle-aged women.

Judul: Algoritme LLL dan Aplikasinya dalam Pembongkaran Sistemkripto Knapsack Merkle-Hellman
Abstrak: LLL algorithm is an algorithm that can be used to determine an approximation of the shortest vector in a lattice. Size reduction algorithm is an important step of LLL algorithm. The LLL algorithm can be applied in many elds. This paper shows how LLL algorithm can be used in breaking one of the famous cryptosystem, namely the Merkle-Hellman knapsack cryptosystem. Merkle-Hellman knapsack cryptosystem is an asymmetric cryptosystem using the subset sum problem as the support of security. Subset sum problem can be transformed into the problem of determining shortest vector in a lattice, so that LLL algorithm can also be used to solve the subset sum problem. Since the subset sum problem can be easily solved by applying LLL algorithm, then the Merkle-Hellman knapsack cryptosystem can also be easily be destructed.
