Judul: Efek Infusa Serai Dapur (Cymbopogon citratus) pada Kadar Glukosa dan Asam Urat Darah Tikus
Abstrak: Serai dapur (Cymbopogon citratus) merupakan salah satu tanaman rempah yang memiliki manfaat sebagai herbal. Serai dapur memiliki kandungan fitokimia berupa flavonoid, alkaloid, tanin, terpen, fenolik, antosianin, steroid, saponin, isoflavon, kumarin, lignin, katekin, isokatekin, dan asam askorbat. Penelitian ini bertujuan untuk melihat pengaruh pemberian infusa serai dapur (Cymbopogan citratus) 20% dan 80% terhadap kadar glukosa dan asam urat darah pada tikus. Sebanyak 30 ekor tikus jantan dibagi menjadi 3 kelompok yaitu kontrol, infusa serai 20%, dan infusa serai 80%. Sampel darah dikoleksi dari ekor kemudian dianalisa kadar glukosa dan asam urat menggunakan test meter (Easy Touch). Rataan kadar glukosa darah menunjukkan hasil yang bervariasi pada ketiga kelompok. Rataan kadar asam urat menunjukkan kecenderungan terjadinya penurunan pada ketiga kelompok. Penurunan kadar asam urat yang paling besar terlihat pada kelompok infusa serai 20%. Pemberian infusa serai dapur pada tikus menunjukkan kadar glukosa darah yang berfluktuasi dan berpotensi menurunkan kadar asam urat dalam darah., Kitchen lemongrass (Cymbopogon citratus) is one of the spice plants that has benefits as herbs. Lemongrass contains phytochemicals such as flavonoids, alkaloids, tannins, terpenes, phenolics, anthocyanins, steroids, saponins, isoflavones, coumarins, lignin, catechins, isocatechins, and ascorbic acid. This study aims to see the effect of giving 20% and 80% infusion of kitchen lemongrass (Cymbopogan citratus) on blood glucose and uric acid levels in rats. A total of 30 male rats were divided into 3 groups: control, 20% lemongrass infusa, and 80% lemongrass infusa. Blood samples were collected from the tail and then analyzed for glucose and uric acid levels using a test meter (Easy Touch). Mean blood glucose levels showed varying results in the three groups. Average uric acid levels showed a tendency to decrease in all three groups. The greatest decrease in uric acid levels was seen in the 20% lemongrass infusa group. Giving lemongrass infusion to rats shows fluctuating blood glucose levels and has the potential to reduce uric acid levels in the blood.

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.
