Update as of 24 July 2018: I gave my wife all of the copies of documents, bought a green folder for them at Gramedia, and asked her to deliver them with the 100k IDR to the KanIm... She was sent to several different floors of the building and finally got to the right place to pay. They then asked her why she had not just paid it through an ATM... After she drove for 90 minutes to get there... Suffice it to say that she is not pleased with me right now.4. After the application has been submitted online with all the documents, you should receive an email the same day (if you submitted your application in the middle of the night/early morning), or the next day (if you submitted afternoon), inviting you to come to South Jakarta immigration to pay the sum of 100,000 rupiah. This can NOT be done online. But you do not have to go in person, you can grant power of attorney to someone.

Either way, the email will tell you to bring a handful of documents to Jakarta. Ignore this and bring photocopies of ALL of the documents above (a to i), with the exception that you can just bring the passport data page, not the whole book. In addition, the documents which you signed and affixed with materai should all be the originals. The documents need to be in a GREEN folder, otherwise you will be told to go away. To send the documents to Jakarta you can use the Indonesian post office, or Tiki service tiki.id. Bear in mind that whatever service you use will arrive too late for same day trip to immigration, so you must go the next day. In addition, Indonesian civil servants don't do much work on Fridays, so if you submit on Friday then you probably can wait too. If you are in a hurry you can post the documents to your Jakarta contact immediately upon online submission.
