COMPARISON OF MATERIALS IN THE CONSTRUCTION OF BALE TANI HOUSES AND BALE LUMBUNG IN SADE VILLAGE, CENTRAL LOMBOK

Abstract

This study discusses the use of local materials in two traditional Sasak buildings in Sade Village—Bale Tani and Bale Lumbung—as representations of sustainable vernacular architecture. The purpose of this research is to identify the types of materials used, their functional roles within the buildings, and the ecological as well as cultural values embedded in their application. The research employs a qualitative descriptive method with a literature review and field observation approach. The results indicate that each material serves a specific function according to the building’s context. Bale Tani utilizes coconut wood, bamboo, clay, thatch, and natural fibers to maintain thermal comfort, enhance energy efficiency, and harmonize with the tropical environment. Meanwhile, Bale Lumbung employs hardwood, bamboo, natural stone, thatch, and natural fibers to ensure structural durability, air circulation, and protection of harvested crops from humidity and pests. The selection of materials for both buildings is based on local availability, ease of maintenance, and resistance to climatic conditions. Moreover, the application of passive design principles and traditional construction techniques reflects the Sasak people's local wisdom in creating environmentally adaptive architecture. In conclusion, Bale Tani and Bale Lumbung embody the concept of sustainable vernacular architecture, integrating functional, ecological, and cultural aspects while serving as inspiration for contemporary environmentally friendly architectural design.
