This is a typical Javanese or Madurese tombak of ordinary quality. The type of thing that would be issued to guards, or in early times to levies.
The long tang is usual for tombak that were actually intended for use, later tombak, say form mid-19th century in Jawa, often had shorter tangs, and old tombak that were remounted as daggers or into display shafts frequently had the tang shortened. This tombak is a definite user, probably Mataram era, but unlikely to be from the Mataram heartland, more likely East Jawa or Madura.
It is a pretty fair example.
