The source of this information is from the Immigration website, here:
https://www.imigrasi.go.id/en/hubungi-kami-kantor-imigrasi/  
I downloaded the list of offices from the website as of March 2022.
I do not know how up to date the information is.

This version only attempted to locate the city where an office can be found, and in some cases that was very approximate.  These are NOT exact locations.  There is a corresponding PDF document that provides street addresses (in most cases), or you can go directly to the Immigration website (link above).

My document, and an updated version of the office locations, can be downloaded from here:
