For understanding activity and evolution of active galactic nuclei (AGN), it is
essential to investigate the fueling and feedback processes in AGN. Recent observations
have shown that jet/outflow activities from AGNs can heavily influence gas around the
center and the fueling process.  In this talk, I present the results from the first ALMA
observations of NGC613, a nearby galaxy with AGN. Multiple line observations at high
resolution (0.4กษ, 40pc) reveal abundant molecular gas in the star-forming ring
(r=250~350 pc) and circum-nuclear disk (CND, r<90 pc). We found that the temperature in
the CND is higher than that in the ring, and the jet activities heavily influence the
molecular gas around the center, indicating suppression of star formation in the center.
