Many survivors said they had yet to see government aid more than a week after the quake killed more than 6,200 people in Yogyakarta and Central Java provinces on Java island, and were relying on relatives and friends to ferry in emergency supplies.
Aid groups set up medical centres in devastated villages, to treat injuries and prevent infections, and distributed hundreds of tents to help the tens of thousands of homeless.
Indonesia's foreign minister said no more international medical aid was necessary and groups should focus on reconstruction.
Many survivors are already trying to rebuild their homes themselves with wood scraps and salvaged bricks but few have the money to buy building materials.
''Yes, I'm scared it will collapse again but I have no money to rebuild it any other way,'' said Tito Harjono, 66, adding that he had been buried under the timber roof after the quake.
The Indonesian government has pledged to give owners of completely flattened houses 30 million rupiah ($3,200) each for reconstruction.
Energy minister Purnomo Yusgiantoro told reporters power in the quake zone has been largely restored, and there would be no charge for reconnection.
''Electricity can flow now from east to west. There are no problems any more,'' he said, adding that it was up to the owners of ruined homes when they wanted to be reconnected.
