Abstract

Bebak, the local building material of East Nusa Tenggara, has long been used as the primary building material, especially as wall material. However, bebak wall construction commonly used today is not yet ideal in terms of its material protection and function. Bebak is a relatively quick damage construction due to termites, which eventually causes the enclosed space's thermal conditions less comfortable. This research is part of the quality improvement program of healthy housing in that region, which focuses on bebak wall protection by plastering the wall with concrete plaster. Two scale models were examined; a wall plastered only on one side, and a wall plastered on both sides. By using a simple construction approach, the research aims to evaluate the bebak protection technique's effects on the construction stability and the bond strength between the bebak composite wall materials. The results of visual evaluations revealed that single-sided plaster on bebak walls could maintain the construction stability and the bond strength of the composite material better than the double-sided one. Furthermore, the evaluation also reveals additional benefits of the plastered walls for the users, such as adaptability and simplicity of modular wall replication to build affordable healthy housing.

Abstract

Bamboo has been used for a long time as a material for simple to complex structures. Many advantages of bamboo as a building material makes it suitable for buildings in disaster-prone areas. Bamboo is however prone to humidity, which could cause fungi and moss to emerge and endanger the building structure. Pedestal foundation made of concrete or stone is often used to reduce this risk as for its action as a barrier of direct contact between soil and bamboo. Nevertheless, water from damp soil or rainwater can still penetrate the foundation by capillary transmission through the foundation’s pores. This research proposed a hollow pedestal foundation model with larger pores and compared its ability to reduce moisture on bamboo columns to an ordinary pedestal foundation. The case study is a temporary post-disaster housing project of 13 houses in Muntilan, Central Java, Indonesia, which was built on an active rice field. Visual examination showed that after 5 years of occupancy, bamboo houses built on hollow pedestal foundations still firmly stood without apparent attacks of fungi or overgrowing mold, whereas the moisture measurement showed that the usage of hollow pedestal foundation could reduce the humidity level in the bamboo column almost twice as fast compared to solid pedestal foundation.
