The resource-rich country has been trying to lift GDP growth significantly, but despite heavy infrastructure investment by the government, the pace has remained about 5% for years.
The median forecast from 16 economists in a Reuters poll was for Southeast Asia's largest economy to have expanded 5.05% in April-June from a year earlier, compared with the 5.07% in the first quarter.
Household consumption, which accounts for more than half of GDP, likely remained stable, helping the headline growth rate stay above 5% while exports were weak, said Andry Asmoro, Bank Mandiri's chief economist.
"Export growth continued to face some hurdles in Q2, including weakening global demand and lower commodity prices," said Asmoro, who predicted 5.06% GDP growth.
Finance Minister Sri Mulyani Indrawati on July 16 predicted 5.1%, reflecting weaker government spending, but an expected pick-up in investment.
TAX CHANGES

"Our domestic factors are contributing something positive for the GDP growth momentum and the global condition can also contribute a positive nuance," Indrawati said on Thursday.
The central bank has also jacked up efforts to increase economic growth momentum by cutting the benchmark interest rate and bank reserve requirements last month, though Governor Perry Warjiyo has said the impact on growth will be felt more in 2020.
President Joko Widodo, who won re-election in April, has promised to be even more business-friendly in his second five-year term, pledging to cut corporate tax rates, revise rigid labour laws and increase investment in infrastructure and education.
Indonesia could lift its GDP growth to an annual average of 5.4%-6% during Widodo's 2019-2024 term, according to a proposal from the planning ministry.
The International Monetary Fund, which predicts a 5.2% rate for 2019, sees a 5.3% medium-term growth rate in Indonesia.
