What are These Two Indonesian Knives, and Where From???

[CharlesS]

I picked up these two old Indonesian knives recently. They do not seem to perfectly fit any particular form, using primarily Zonneveld's Traditional Weapons of the Indonesian Archipelago as a reference.

Can anyone help with classifying exactly what these are and what area they are likely from?? Note that one has a hilt very similar to a Javanese keris.

The larger one is 17.5 inches overall, and the smaller one is 14in. inches overall.

Thanks in advance!
