Judul: Peran Ekstrak Tempe pada Masa Prapubertas terhadap Kinerja Reproduksi Tikus Betina Rattus norvegicus
Abstrak: Tempe extract is one of soybean processed that has phytoestrogens within it. Research was conducted to analyse the potency of tempe estrogenic at prepuberty periode to reproduction system in female rats (Rattus nonvergicus) at the age of 21 days. Rats were divided into control group (without given tempe extract) and treatment group (given 6.25 g/kgBW tempe extract). Tempe extract were given during 28 days. At the age of 28, 42, and 56 days, samples of ovarium, uterus, and blood were collected from the female rats. Parameters observed were body weight, ovarium weight, uterus weight, and reproduction hormone content which were estrogen and testosteron. Data were analysed using Independent Samples T-Test methode with 95% confidence interval. Results showed that increasing of ovarium weight of treatment group is higher than control group at the age of 42 days. Phytoestrogens given is assumed to increase estrogen and testosteron at female rats at the age of 42 days.

Judul: Peran Pemberian Ekstrak Tempe terhadap Organ Ovarium dan Uterus Tikus Betina Prapubertas
Abstrak: This research was conducted to study the potential of tempe phytoestrogen to the reproduction performance in female rats (Rattus norvergicus). There were 18 of 21-days old of female rats were divided into two groups, which were control group without given tempe extract and treatment group that has been given the tempe extract with a concentration of 0.25 gr everyday at the the age of 21-days old until 48 days-old. The female rats were sacrificed at the age of 28th, 42nd and 56th days-old to collect the samples of blood, ovarium and uterus. Parameter measured were the rate of estrogen hormone, wet and dry weight, water content, total of DNA and total of RNA. Data were analysed using Independent Samples T-Test method with 95% confidence interval. Result showed the increasing of wet and dry weight of ovarium and uterus in treatment group at the age of 42 days but there was no influence on the total of DNA and RNA of organs.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
