Indonesia has posted its slowest pace of economic growth since 2009, which may put pressure on the government ahead of July's presidential elections.
Southeast Asia's biggest economy expanded by 5.2% in first three months of the year, which was below the median forecast for 5.6% growth.
The weaker-than-expected data follows a series of aggressive interest rate hikes by the country's central bank.
Indonesia's economy has also been impacted by slowing foreign investment.
"The general trend in Indonesia over the past couple of years has been one of slowing growth," Daniel Martin from Capital Economics said.
With tight monetary policy weighing on the economy, the weakness looks set to last."
