Suppose that two chords, drawn from the point \( (1, 2) \) on the circle \( x^{2}+y^{2}+x-3y=0 \) are bisected by the \( y \)-axis. If the other ends of these chords are \( R \) and \( S \), and the midpoint of the line segment \( RS \) is \( (\alpha,\beta) \), then \( 6(\alpha+\beta) \) is equal to:
