Prabowo took office on Sunday as the eighth Indonesian president, taking the mantle from Joko 'Jokowi' Widodo.
The cabinet with 109 officials is the largest since 1966 when Indonesia's first president Sukarno formed a lineup of 132 ministers.
Subianto, a former military general, officially took office on Sunday, leading a coalition of seven political parties that supported his victory in the February election.
One of his first moves was to officially inaugurate a total of 48 ministers, with 22 new ministries and agencies, to help rule the country over the next 5 years.
