Indonesia's economy grew a slower-than-expected 5.01 percent in the second quarter as a dip in household consumption and a slowdown in key commodity prices hit the resource-rich country, data released Monday showed.

The year-on-year expansion was unchanged from the first quarter but below the government target of 5.2 percent growth for 2017.

"We have to admit that the 5.01 percent growth is below our expectation, but I'd say it's still quite good considering the global economic conditions and the decreasing commodity prices,” Suhariyanto, the head of Indonesia's Central Statistics Bureau, said.

President Joko Widodo came to power in 2014 on a pledge to boost economic expansion to seven percent but his government has struggled to lift growth rates in Southeast Asia's largest economy, which is rich in resources but has suffered from a slump in commodity prices.

Household consumption, which accounts for more than half of Indonesian GDP, was the main driver of growth, expanding 4.95 percent percent year-on-year but down from the 5.07 percent growth seen in the second quarter last year.

Growth in trade dipped, due to a slowdown in domestic goods production and the supply of imported goods, Suhariyanto said.

Capital Economics described the result as another disappointingquarterfor Indonesia.

"Looking ahead, we see little prospects of a sustained recovery," Gareth Leather, senior Asia economist at the consultancy, said.

Authorities have been scrambling to boost growth, with the central bank slashing interest rates six times last year and Widodo announcing a series of economic stimulus packages.

Although Widodo's pledge of raising growth rates to seven percent a year looks unlikely, Indonesia's economic fundamentals have improved in recent years.
