I think this may be the reason for your error:

Declaration

protected function getAktiva()

essentially this condition means that this proteted class can only be accessed within the originating class (class indukPerusahaanABC) and within all of its eventual subclasses.

[broj1]

If you want to use this function outside the object make it public.

public function getAktiva(){
    return $this->aktivaLancar+$this->aktivaTetap;
}

This is usually the purpose of the get functions (getters): to get the data stored in protected or private variables.
