there are two key principles which are not part of immigration law:

1) foreign investment can only be done via a PT PMA

2) work by foreigners can only be done by someone with a work permit.

Therefore for example if you started a business selling noodle soup, then that would constitute 'foreign investment', and would be illegal.

If you got a job working in a noodle soup shop, then that would be 'foreign manpower' and require a work permit ($1200/year, possible for chefs e.g., those with niche skills like making foreign food).

So basically none of these residence permits give you the right to work, they are merely the permission to reside in Indonesia. The exception to this is the PT PMA residence permit where you have the right to be a director of the one specific PT PMA that you own shares in.

The different residence permits can be classified as:

1) cannot get a work permit (e.g., pensioner)

2) maybe get a work permit (e.g., spouse/ex-Indonesian)

3) must get a work permit (working ITAS)
