According, to the app... It seems that from Pengangkutan Penumpang to Stasiun Jakarta Kota you need to start with a long 19m walk, then at Klender take Bekasi until Jatinegara, change to Kota-Jatigenara until Stasiun Jakarta Kota.

PS: alright, as you see I like to know about public transport in cities Please continue with the testing and try to find out why so many users say they could find about their cities when it seems to be there (how complete and accurate I don't know).
