Investigation of Termite Attack on Cultural Heritage Buildings: A Case Study in Aceh Province, Indonesia.

Surveys of the conditions of termite attack were conducted in two regencies, Pidie and Greater Aceh, Aceh Province, Indonesia (40 houses in each location). Interviews were also conducted with home owners to collect data on the building history; culture, such as daily life in the house; the frequency and intensity of termite attacks; and traditional knowledge for avoiding and/or suppressing termite attacks. We found that 51% of traditional houses were infested by two termite species: Coptotermes gestroi and Nasutitermes matangensis . The lower parts of traditional houses were frequently attacked and severely damaged by termites. Previous land use and the ages of the traditional houses affected the intensity of the termite attacks. Several measures for avoiding and/or suppressing termite attacks on cultural heritage buildings are also proposed.
