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  Tepung Tanaman Tarbangun (Coleus amboinicus Lour) Dalam Ransum Dan Waktu Pemberiannya Yang Berbeda Terhadap  Produksi Air Susu Induk Babi
Abstrak: Tarbangun (Coleus amboinicus Lour) plant can be utilized to increase milk production of sow during lactation period. Sufficiency of milk production can reduce the death risk of newborn piglets. The research conducted from June to Agust 2010 in PT. Adi Farm Jl. Raya Solo, Seragen, Jawa Tengah. The design of this research was complete random design method with two factor: level of tarbangun meal (0, 2.5, 5 and 7.5%) and feeding time (after 107 days of pregnancy and postnatal). The result show that addition tarbangun meal in sow’s diet had very significant (P<0.01) effect on sow feed consumption and significant (P<0.05) effect on day milk production, lactation milk production and interaction of level and feeding time on litter size at weaning. The result show that addition tarbangun meal in sow’s diet hadn’t significant effect on milk production/suckling period, litter size at birth, pig weight at birth and mortality. Result of this research showed that at level 5% after 107 days of pregnancy, tarbangun meal in sow’s diet gave highest milk production.

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.
