Impulse = change in linear momentum .

Initial momentum of ball= mu
=0.15 × 12 =1.8 kg.m/sec

Final momentum of ball = -mu
= - 0.15 × 12 = -1.8 kgm/sec
Change in momentum of ball =final -initial
= -1.8 -1.8 = -3.6 kgm/sec

So,
Change in momentum of bat = -change in momentum of ball

Change in momentum of bat =3.6 kgm/s

Impulse imparted to ball =change in momentum of bat = 3.6 kgm/s
