The 27-year-old lass said Indonesian fans are expected to fill up the competition arena as karate is a popular sport in the republic.
"This is not my first competition in Indonesia. Expect a big home crowd and their cheering will make the heartbeat faster," she told Bernama today.
However, the silver medalist at 2010 Guangzhou Asian Games is confident of coping with the pressure.
"What is important is confidence but I don't want to be over confident and emotional. Small things must not be exaggerated. I just want to give my best."
Jamalliah who will compete in the under 68kg Kumite is determined to win two gold medals via the individual and team events.
She is also lining up a hattrick after winning the gold at Vientiane SEA Games two years ago and Korat SEA Games in 2007.
