For drawings and photos of traditional housebuilding in Indonesia--albeit on Sumbawa Island, nearer the eastern end of the island chain--see Timber Framers News 16, "House Building in Donggo."
Termites are certainly a traditional problem, countered by building well off the ground on footed posts, and keeping the ground clear and swept under the building.
A number of you in this thread write eloquently or cogently or both, and I urge you to send me (journal@tfguild.org) accounts of your timber framing discoveries and opinions.
Regards to all,
