The head of the local search and rescue agency, Al Amrad, said in a statement the boat carried five journalists, two crew members and a guide.
He was also quoted by broadcaster Kompas TV as saying that the search had been halted for the day, and would resume on Wednesday morning.
Antara news agency confirmed its photographer, Muhammad Bagus Khoirunas, was one of the passengers on the missing boat.
