Indonesia's gross domestic product grew 5.01 percent in the third quarter from a year earlier, its slowest in five years, highlighting the challenge that the new President Joko Widodo faces trying to turn around Southeast Asia's largest economy.
Growth in the G20 economy has trended lower since a peak in 2010 as exports suffered from weak global demand, while a wide current-account deficit plus political uncertainty in an election year has unnerved investors.
"We doubt that growth will slow much further from here, but we don't expect it to rebound either," said Gareth Leather, an economist at Capital Economics, adding that exports are likely to remain weak.
Exports were 0.7 percent lower in the third quarter from a year ago, following on from a fall of 1.04 percent in the second quarter.
Imports were down 3.63 percent in the third quarter from a year ago, after 5.02 percent fall in the second quarter.
Elected in July and sworn in late last month, Widodo has pledged to boost economic growth to 7 percent on average during his five-year-term.
In the previous quarter, gross domestic product (GDP) grew slightly quicker at 5.12 percent, but was also the slowest rate since the third quarter of 2009.
During July to September, investment rose 4.02 percent in the third quarter from a year ago, and down from the second quarter rate of 4.53 percent. It had been growing twice as fast two years ago.
