Hello Ridho,
Looks like a double Naga to me (gandhik naga penganten).
I don't think any dhapur can be assigned to this keris: IMHO it does seem to be a Karmadikan blade that doesn't follow any traditional pakem AFAIK.
I hope some of our forumites will contribute similar examples for comparison. I've seen a few (apparently of lesser quality than yours) - can't post any currently for sale though.
BTW, more light will allow you to take better pics! Here is a thread with lots of tips:
