I don't know how long the blade is. My first impression was a ceremonial knife from Bali as shown in the book by Van Zonneveld on the first color page and on page 112.
Looking at the blade it looks more like a pedang. I don't think it is a pedang lurus but an other pedang variety, probably from Java or Bali.
Nice blade by the way with that Singha on it.
