Welcome to the forum klewang!
I looked in the book of van Zonneveld. There you can find a description of the "chunderik" or "chundrik":
Chunderik:
"The name given to weapons of widely differing forms. For instance: a long sabre, a klewang or a small dagger the blade and hilt of which are forged from one piece and thus related to the so-called keris majapahit. The "chunderik" may sometimes serve as the point of a spear."
I wouldn't call your sword a "golok" either. Although all my indonesian friends call everything a "golok", whenever you can say in dutch "kapmes".
I would just call it some kind of little Javanese sword.
But I think yours is no piece used as working tool for "een paar boompjes om te hakken"
, but used as some kind of status symbol.
vriendelijke groet,
