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: Pengaruh Taraf Pemberian Tepung Daun Bangunbangun (Coleus Amboinicus Lour) Dalam Ransum Induk Babi Menyusui Terhadap Nilai Ekonomi Penampilan Anak Babi Sapihan
Abstrak: In the tropic, there was a wild plant called bangun-bangun. This plant is belived could increase the milk production of mammal, especially milk production of woman whose feeding their baby. The aim of this research is to study the economy influance of bangun-bangun leaf meal which is added to the sow’s diet at different level (0; 1,25; 2,5; and 3,75%). The design of this research was completely random design with four replication. The observed parameter was litter size, sow feed intake, litter weight at birth, litter weight at weaning, litter weight gain, milk production, body weight gain, feed cost, total production cost and the weaned piglet economy effect. Result of this research showed that at level 1,25% bangun-bangun leaf meal in sow’s diet, gave biggest profit than another level in economy of weaned piglet. The profit of a weaned piglet can increase until 17,21% from the usual advantage (level 0%). Bangun-bangun leaf meal in sow’s diet didn’t have significant effect on litter size, sow feed intake, litter weight at birth, pig weight at weaning, litter weight gain, milk production and body weight gain.

Judul: Aplikasi Keamanan Data Shapefile Menggunakan Algoritme Kriptografi AES
Abstrak: Geographic Information System (GIS) is an important part of information systems because GIS contains classified spatial data and information in any fields. This research is focused on securing GIS vector data (shapefiles) and also reading the shapefiles. A shapefile combines maps and tables, both have a related information on each other. The usage of Rijndael (AES) cryptography algorithm and Key Derivation Function (KDF) would assist in improving the security of shapefiles. However, besides cryptography algorithm, authentication service is also implemented to improve the security mechanism in order to prevent unauthorized users gain full access to the application which provides the shapefile security. The application was executed using fifteen shapefiles and analyzed in terms of loading time, size, and iteration count between the encrypted and non-encrypted shapefiles. The biggest shapefile (33.79 MB) could be decrypted and displayed in two seconds with 10000 iterations (ten times in complexity from the standard iteration, which is 1000) and fifteen characters of salt. By using this application, authorized users could read their shapefiles with common functions (zoom, extent, pan, etc) and protect the classified one with no penalty in overall performance.
