Forbes Magazine published on Thursday the 2009 list of Indonesia's 40 richest people. The owners of the Djarum group, Budi and Michael Hartono, still topped the list with estimated wealth of $7 billion.

The magazine wrote that investors were in love with Indonesia after the country's benchmark stock index rose 115 percent in local currency in the past 12 months – Asia's second best performer behind China's Shenzhen SE Composite.

It was no surprise that the wealth of Indonesia's richest people continued to increase. The collective worth of the nation's top 40 has doubled to $42 billion from $21 billion last year and is up $2 billion from its prior peak in 2007, the magazine said. Resources kings were prominent on the list. Low Tuck Kwong, owner of Bayan Resources, was a newcomer on the list after his stocks rose 474 percent in the last year.

Another coal billionaire, Aburizal Bakrie, chairman of the Golkar Party, improved his ranking after his holding in Bumi Resources increased in value.
