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: 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.

Abstrak: The solution of Schrodinger equations with plasma Coulomb potential in spherical coordinat results solution wave function and energy plasma particle. Electron probability density at Debye length with thermal effect same as ion, which indicates plasma in neutral state. Electromagnetic waves perturbation of an electric field given to result wave function perturbation system. The probability density of plasma particle due to electromagnetic waves perturbation is the largest when an electromagnetic waves frequency 1.41 times the plasma frequency .
