On the long distance (night) ferries there is always the choice between VIP (AC, few people), business and ekonomi (fan, lots of people) - the price above is for ekonomi, VIP will be more expensive.

Payment is most likely still in cash.
In case it would have changed - the cashless payment is complicated: you need to pay online via transfer (indonesian bank only) or via (indonesian) flashcard (BNI, BRI, Mandiri, ...) The latter you can buy and top up in any Indomaret/Alfamart. An alternative option is to go buy the ticket in the nearest Indomaret/Alfamart and you can pay cash there (at a premium of course). With the payment slip you can enter the port where this paper will be changed to a ticket, with which you can board the ferry.
