if you're a University student, u can join BUlan Sabit Merah Malaysia, BSMM (previously knows as PBSM)

I'm currently an AJK in my univ's BSMM committee, helped run blood drives (even organized one myself), go for stand-by duties at univ's various programs (even those national events like the paralympics) & joined numerous charity events under BSMM.

if ur not a student, u can still register under a nearest university as a member.

hope this helped.
