A tourist visa for US citizens can obtained upon arrival for 25 USD, preferably cash, exact change.
After you deplane you first stop will be immigration. Before immigration there will be some well signed, official, booths for obtaining visa on arrival (VOA). There will be a fee of 25USD (this it not a bribe or anything of that nature, but a legitimate fee). It's payable by cash or credit card. I would recommend having enough cash on hand in case the credit card system is not operational/available. There are also ATMs nearby and you may be able to pay in Indonesian Ruppiah, which is what the ATMs will probably dispense. 1 USD ~= 10,000 IDR.
Once you have paid the visa fee they will place your visa in your passport. From there it is a straight shot through immigration in a line marked for people who did VOA. No need to stand in the line for non-VOA visa people. Someone will check your passport to make sure there's a visa in there. Then on to baggage.
Some of these details may apply specifically to Soekarno-Hatta International Airport (CGK) but the principles should apply throughout Indonesia.
