The oil company initially called the pitch in February this year, but it was shelved abruptly for undisclosed reasons.
According to reports, the oil giant has been facing resistance from consumers who are unwilling to switch to LPG due to the inconvenience of the conversion process.
The Indonesian government launched the kerosene-to-LPG conversion programme in December 2006, to be completed in 2010, with Pertamina as the main implementing organisation.
Pertamina was aiming to provide LPG cylinders and gas stoves to 20 million households by the end of this year, but may not be able to meet this year's target due to a lack of canisters and refill stations.
