Judul: Pengaruh Aromaterapi Minyak Atsiri Jahe Terhadap Kadar Trigliserida dan Kolesterol Darah Tikus yang Diberi Pakan Tinggi Lemak
Abstrak: The study aims to determine the effect of ginger (Zingiber officinale) essential oil via inhalation on blood triglyceride, total cholesterol, High Density Lipoprotein (HDL) cholesterol, and Low Density Lipoprotein (LDL) cholesterol level of rats that fed high fat diet. Eighteen albino rats (Rattus norvegicus) were devided into three treatments groups. The treatments were K1 (standard diet) as negative control, K2 (high fat diet) as positive control, and K3 (high fat diet + ginger essential oil inhalation). Blood samples were collected after 5 weeks of treatment period. The result showed the level of triglyceride, cholesterol, and HDL cholesterol at treatment K3 tend to be lower than treatment K2. LDL cholesterol level at treatment K3 show higher result than treatment K2. From the result of this study cocluded that inhalation of ginger essential oil can lowering triglyceride, total cholesterol, and LDL cholesterol level and raise HDL cholesterol level.

Judul: Konsentrasi kolesterol dan trigliserida pada serum tikus hiperlipidemia dengan perlakuan inhalasi minyak atsiri bangle (Zingiber purpureum)
Abstrak: Bangle mengandung minyak atsiri berupa sineol dan terpinen. Minyak atsiri rimpang bangle diduga dapat menurunkan konsentrasi kolesterol dan trigliserida. Penelitian bertujuan mengukur konsentrasi kolesterol dan trigliserida pada serum tikus hiperlipidemia dengan inhalasi minyak atsiri bangle (Zingiber purpureum). Perlakuan dilakukan secara in vivo terdiri atas 5 kelompok, yaitu kelompok normal, kelompok hiperlipidemia (tanpa inhalasi), kelompok inhalasi minyak atsiri kasar, kelompok inhalasi minyak atsiri fraksi 1, dan kelompok inhalasi minyak atsiri fraksi 4. Penelitian dilakukan dengan metode enzimatik, yaitu CHODPAP (Cholesterol Oxidase Para Aminophenazone) dan GPOPAP (Gliserolphosphat Oxidase Para Aminophenazone) untuk mengukur konsentrasi kolesterol dan trigliserida dengan menggunakan spektrofotometer. Hasil yang didapatkan adalah kelompok inhalasi minyak atsiri fraksi 4 memiliki konsentrasi kolesterol 211,536 mg/dL dan konsentrasi trigliserida 191,821 mg/dL lebih tinggi jika dibandingkan kelompok lainnya. Pemberian minyak atsiri kasar dan minyak atsiri fraksi 1 mempunyai konsentrasi kolesterol yang lebih rendah daripada kelompok hiperlipidemia (tanpa inhalasi). Kelompok inhalasi minyak atsiri fraksi 1 dan minyak atsiri kasar berpengaruh menurunkan kadar kolesterol namun tidak berpengaruh menurunkan trigliserida. Konsentasi kolesterol dan trigliserida di dalam darah memberikan korelasi yang negatif terhadap bobot badan.

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.
