International collaboration research for preservation of wooden structures in Indonesia -Application of Japanese restoration techniques and significance of preservation

本研究的重点是印尼传统木结构房屋的保护技术。在1994年举行的奈良会议上，日本传统的木制品修复技术，即固定木材以交换或切割劣化部分，已被批准。在借鉴日本木结构建筑修复方法的基础上，如何在热带气候条件下对作为文化遗产的印尼木结构建筑进行修复？ 该研究进行了两个历史街区，日惹的Kotagede和尼亚斯岛的Bawomataluo村。一些地区的修复案例将旧房屋的所有木材材料转换为新建筑。木匠们过去常常把所有的木头部件都换掉，尽管有一部分已经变质了。这可能是一个理论上的方法，以保持传统风格的房子，其木材材料将是易腐的热带气候。

This research focuses on the conservation techniques for the traditional wooden houses in Indonesia. Japanese traditional wooden restoration techniques which fix wood materials to exchange or cut a deterioration part has been authorized in the Nara convention held in 1994. Based on the restoration method of wooden buildings in Japan, how should be done to restoration the Indonesian wooden houses as a cultural property in the climate of tropical zone? The research conducted two historic districts, Kotagede in Yogyakarta and Bawomataluo village in Nias island. Some restoration cases in the districts have converted all the wood materials of the old houses for rebuilt as a new building. And the carpenters used to exchange the whole wood parts in spite of a part of that's deterioration. It might be a theoretical method to maintain the traditional style of the house in which its wood materials are going to be perishable in tropical climate.
