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 ekstrak tempe pada masa prapubertas terhadap kinerja reproduksi tikus betina Rattus norvegicus
Abstrak: Ekstrak tempe merupakan salah satu bentuk olahan kedelai yang mengandung fitoestrogen. Penelitian dilakukan untuk menganalisa potensi estrogenik tempe pada masa prapubertas terhadap kinerja reproduksi yang dilakukan menggunakan tikus (Rattus nonvergicus) betina berusia 21 hari. Tikus dibagi menjadi kelompok kontrol (tanpa diberi ekstrak tempe) dan kelompok perlakuan (diberi ekstrak tempe dengan dosis 6.25 g/kgBB). Pemberian ekstrak tempe dilakukan selama 28 hari. Pada umur 28, 42, dan 56 hari dilakukan pengambilan sampel ovarium, uterus dan darah. Parameter yang diamati adalah bobot badan, bobot ovarium, bobot uterus dan kadar hormon reproduksi berupa estrogen dan testosteron. Analisis data menggunakan metode Independent Samples T-Test dengan selang kepercayaan 95%. Hasil penelitian menunjukkan peningkatan bobot badan, bobot ovarium, dan bobot uterus kelompok perlakuan lebih tinggi dibandingkan dengan kelompok kontrol pada umur 42 hari. Pemberian fitoestrogen diduga dapat memberikan pengaruh berupa peningkatan estrogen dan testosteron yang terjadi pada umur 42 hari.

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.
