Abstract
Lamban Balakh, a traditional house in Indonesia shows how rich the cultural heritage and environmental adaptation. Traditional houses designed to adapt to the surrounding natural conditions, including earthquakes, use local materials and construction techniques that have proven effective over time. Despite its ability to withstand earthquake shocks, as demonstrated during the Liwa earthquakes of 1933 and 1994, there is still a limited in-depth understanding of the unique structural system of the Lamban Balakh building. This study aims to explain the unique structural system of Lamban Balakh and how it functions as an adaptive strategy to reduce earthquake risk in the Lampung community. The study utilized a mixed-method approach, combining a systematic review with analyses of literature (journals, books, and earlier research) and data collected through on-site surveys, including observations, interviews, and documentation of structural details to find the unique structural features and adaptable construction methods of Lamban Balakh. The results suggest that Lamban Balakh's unique system is made up of an elevated stage structure, a flexible thre-part structural separation, a wooden locking joint system, and a bamboo roll system that makes it more flexible during the earthquakes. The building's use of local natural materials, separation of structural elements, stone-pile foundations, and roof shape all make it strong and culturally important. This study finds that Lamban Balakh is a great example of local expertise and creative structural adaptation, making it a great example of earthquake-resistant vernacular architecture in Indonesia.
