Integration of Prefabrication and Modular Construction Methods in Accelerating of Implementation of Post-Disaster Home in Lumajang, Indonesia

Post-disaster is a condition that requires immediate demand for housing to meet the housing needs of disaster victims. The demand for large numbers of post-disaster housing needs will require strategies for time efficiency and effectiveness in arranging building dimensions, building shapes, use of materials, and appropriate construction systems so that implementation mechanisms and use of materials do not produce a lot of waste. This is important because disaster conditions will require the provision of houses for disaster victims in a relatively short time. Meanwhile, conventional building procurement mechanisms often encounter problems regarding the length of the construction process and the large amount of production waste during work implementation in the field. So a more competitive productivity performance in housing procurement is needed to meet the need for large quantities of housing in a short time. The use of procurement methods using prefabrication methods and modular systems needs to be integrated comprehensively so that the speed of construction implementation and the occurrence of construction waste can be minimized. In this research the author will integrate two building techniques, namely fabrication techniques and modular building systems by making building panels that can be produced simultaneously, then assembled in the field using a pre-arranged fabrication system. In the process of assembling the modular building in the form of panels, several relatively light building materials are used, namely using a bar frame construction with classic C-75 Smartruss Canal Material and the covering is 9 mm thick Calciboard. Meanwhile, the roof uses frame construction with a roof covering in the form of x-trap lysaght material 5 mm thick.
