Easier Filter System Setup

i am trying to configure/make  a filter system that let's me select a set of options based on another set of options, basically a filter system for lookups based on lookups, what i understand is using business rules like so...

if Provinsi = DKI Jakarta 

then Kota = (Dropdown => Jakarta pusat, Jakarta Barat, Jakarta Utara, etc)

if Provinsi = Aceh

then Kota = (Dropdown => Aceh Selatan, Aceh Utara etc)

now im trying to find a better way to filter the dropdown without going through them 1 by 1 i want to do it for 5 fields

Provinsi, Kota, Kecamatan, Kelurahan, Kode Pos

and each one needs to have the right option values

can anyone suggest a better way to handle this since i have no idea on how to do this
