I think this may be the reason for your error:


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.

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.
