JAKARTA, July 24 (Reuters) - Indonesia, the world's biggest palm oil manufacturer, is checking fuel with a view to increasing to 40% from 35% the share of palm-oil mixed into biodiesel next year, the energy ministry said.

If implemented, the B40 mandate might increase biodiesel intake to up to 16 million kilolitres (KL) next year, the ministry said, from 13 million KL approximated to be consumed in 2024.

"We hope the trials might be completed in December, so that full application of B40 might be performed in 2025," energy ministry senior official Eniya Listiani Dewi said in a declaration on Tuesday.

The Indonesian Biofuel Producers Association (APROBI) stated the market had the capability to meet B40 demand, with set up capability anticipated to rise to 20 million KL every year next year from 18 million KL now.

"However we will need more raw materials to meet B40 demand," Ernest Gunawan, the secretary general of APROBI informed Reuters on Wednesday.

The biodiesel market would need 13.9 million metric heaps of crude palm oil to produce 16 million KL biodiesel next year, from the approximated 11 million lots required this year, he included.

Indonesia's greatest palm oil association GAPKI stated a decrease in exports implied there would be enough raw products to supply the B40 mandate for now.

But the market would need to examine "which one would be better", GAPKI chairman Eddy Martono stated, referring to the possibility a boost in exports would make providing the domestic market less feasible.

Indonesia's palm oil output is approximated to reach 54.4 million loads in 2024, a 2.26% boost from in 2015, while exports are to decline by 2.47% to 29.5 million lots as domestic usage increased, driven by biodiesel mandate.

The ministry had checked the biodiesel, blended with 40% of palm oil, on a train for the very first time earlier this week, while planning to evaluate the B40 mix on agriculture equipment, power plants and in the shipping industry, it stated. (Reporting by Bernadette Christina and Dewi Kurniawati
