Actually the hilt looks like a Malayan version (regarding the style of ornamentation) of a Madurese type, discussed here:

Perhaps they copied also such hilts, besides Palembang ones:

There is of course the possibility, the hilt is a recent work, done somewhere in Indonesia. It simply don't look like an old Madura hilt to me. Actually most probably the combination hilt+pendokok isn't original, the visible half of bungkul looks strange.
