Hello! 
 
I believe the 'pedang' is Sumatran, traditionally washed and traditionally forged blade. I don't think there was a specific type of pamor constructed, but just made in the traditional way. Some symbols are forged into pedang blades such as 'Batu lapak', but it seems mostly a tradition of forging and strengthening the blade. Similar blades with a small fuller on the forte are often dated around the 18th century. This blade could be genuinely 18th century in my opinion. 
 
The hilt seems a stylistic version of a 'makara', also often seen on Sumatran swords. Mostly varying in different motifs.
