Abstract

This study aims to analyze changes in space in traditional Kerinci traditional houses. Research is research. In this case, the method used is a rationalistic method where this method seeks to explain the actual situation in the field and then tested with existing theories. The method chosen must be appropriate to achieve the research objectives, this chapter also examines in more detail about the research carried out such as research materials, research tools, the course of research, and difficulties encountered during research. The results of research findings that have been carried out on changes in the space in umah lahiek in Mukai Mukai Mudik Village, we can conclude that the changes that occur in the inner space are the addition of sleeping space both in the outer room (umah lua) and in the inner room (umah inside). The addition of this sleeping space has no effect on the shape of the outer floor plan of the umah lahiek unit, but only changes in the pattern of the inner room.

Abstract

Concrete is the main material in building construction. The use of Portland cement as a binder in concrete mixes causes high concrete production costs. Apart from that, cement production also produces high CO2 emissions. Therefore, this research aims to utilize brick waste discarded from the brick industry as a partial substitute for cement in the concrete mixture. The brick powder is sieved to 80 mesh size and then used to replace cement with variations of 0%, 5%, 10%, 15% and 20% based on the weight of the cement. The compressive strength of the concrete was tested at 7, 14 and 28 days. Test results show that the use of brick waste up to 10% can increase the compressive strength of concrete. At 15% and 20% substitution, there was a decrease in the compressive strength of the concrete due to incomplete pozzolanic reaction. So it is concluded that brick waste can be used as a substitute for cement up to 10% in the concrete mixture without reducing its compressive strength. This research can provide solutions for environmentally friendly waste utilization and reduce the use of cement in concrete mixtures.
