Luhut, one of key supporters of President Joko Widodo during the presidential election, said his main duties would be coordinating various parties in the government.

“Give me time to learn (about this job)…As assistant to the President, I will try to do my best to accelerate the President’s programs,” Luhut said after the ceremony in Jakarta today.
