Judul: Pengaruh Pemberian Ekstrak Daun Bangun-Bangun (Coleus amboinicus Lour) dalam Ransum Induk terhadap Penampilan Reproduksi dan Produksi Air Susu Menit (Mus musculus)
Abstrak: Tanaman bangun-bangun (Coleus amboinicus Lour) termasuk kedalam tanaman herbal yang terdapat hampir diseluruh daerah di Indonesia. Daun bangun-bangun (Coleus amboinicus Lour) diyakini oleh masyarakat suku Batak dapat meningkatkan produksi air susu pada ibu yang sedang menyusui. Suatu penelitian menemukan bahwa dalam daun ini terkandung senyawa lactogogum yang dapat meningkatkan produksi air susu. Selain itu, dalam daun bangun-bangun terkandung senyawa-senyawa kimia yang berpotensi mempengaruhi berbagai macam aktivitas biologi, misalnya antioksidan, diuretik analgesik, mencegah kanker, anti tumor, dan anti hipotensi. Penelitian ini dilakukan untuk mengetahui pengaruh pemberian ekstrak daun bangun-bangun (EDB) terhadap penampilan reproduksi dan produksi air susu induk dengan taraf pemberian EDB yaitu R0 (0,00%), R1 (0,05%), R2 (0,10%), serta R3 (0,15%) dalam ransum dan waktu pemberiannya yaitu dimulai pada saat umur kebuntingan 14 hari (H1) dan saat setelah beranak (H2). Peubah yang diamati adalah konsumsi ransum induk, produksi air susu induk (PASI), litter size lahir, bobot lahir, litter size sapih, bobot sapih, pertambahan bobot badan (PBB) anak dan mortalitas. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) pola Faktorial 2x4 masing-masing dengan empat kali ulangan. Data yang diperoleh dianalisa dengan Analysis of Variance (ANOVA), menggunakan Microsoft Excel 2003 dan jika perlakuan berbeda nyata dilanjutkan dengan uji Tukey.

Judul: Pengaruh penambahan tepung tanaman bangun-bangun (Coleus amboinicus Lour) dalam ransum terhadap penampilan reproduksi induk dan anak babi menyusu
Abstrak: Coleus amboinicus Lour has been used as a breast milk stimulant (a lactogogue) by Bataknese people in North Sumatera for houndreds years. The main objective of this study was to investigate the effects of sow dietary addition with bangun-bangun plant meal (Coleus amboinicus Lour) on the reproduction performance of sows and its piglet development preweaning. The design of the research was completely random design factorial (4 x 2) with three replication. The first factor was percentage of addition of bangun-bangun plant meal in feed (0, 2.5, 5 and 7.5%) and the second factor was given time of feed (on day 107th pregnant and day of giving birth). Addition of bangun-bangun plant meal had significant effects (P<0.05) to decrease on birth mortality. The given time of bangun-bangun plant meal in sow feed had significant effects (P<0.05) on early time weaning to estrus interval. Interaction of two factor had significant effects (P<0.05) to increase sows and piglets feed intake, milk production, piglet weight gain per litter, weight at weaning per litter and litter size at weaning but treatment did not affects on gestation and birth time, weight of piglet at birth, litter size at birth, mortality before weaning, sow reproduction cycle and decrease of sow weight. Effects of sow feed addition with 5% bangun-bangun plant meal on day 107th pregnant improve the performance of sows and piglets.

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.
