Wood and steel as a material alternative of concrete replacement in house structures in merauke city

Abstract

Concrete is a building material that is generally widely used as a house structure material in Indonesia. This is very possible considering that the concrete forming material consisting of sand, cement, and gravel is a material that is available in nature and is relatively easy to find. But in certain areas such as in Merauke, there are no materials such as gravel and sand so wood and steel are alternative substitutes for concrete. This study aims to analyze and compare two types of semi-permanent houses that use different materials on the main structure, namely wood material, and steel material. This research is qualitative research with the following stages of research, namely determining the home mouse sample, interviewing people who are considered to have competence in the field of architecture and direct field observation. The results showed that in terms of costs, semi-permanent wood houses were relatively cheaper compared to semi-permanent steel houses. In terms of the appearance of the building, steel material has more advantages, namely not shrinking so that cracks that occur on the wall due to shrinkage of the material as happened in semi-permanent homes of wood can be minimized.
