Instant Construction Design Environmentally Friendly for Building a New Classroom School

The construction of classrooms which are the main means of education and learning activities is always carried out every year, to meet the needs of classrooms which in 2020 are now experiencing a shortage of 15,931 classrooms. The implementation of school construction so far in Indonesia has been carried out in a self-managed manner, and the construction system uses conventional methods, so it requires a lot of human resources, requires a very long time, and always leaves construction waste. The existing precast construction method is still limited to certain building components, so if the implementation of classroom construction uses the precast method, it is still combined with conventional methods and only speeds up the time a little, and still leaves construction waste, therefore there needs to be a solution so that the implementation of classroom construction does not require a lot of human resources, does not require a long time, and does not leave construction waste. To solve this problem, this research offers an instant school room construction design solution, as a method of implementing the construction of new classrooms. This study uses a pure experimental method and results in the construction design of all building components in classroom construction, including modules of sloop structure components, main columns, beams, walls, floors and roof truss. With this design building components can be produced precast, so that the implementation of the construction of new classrooms at school locations, only providing locations that are ready, then assembling all building components that are produced precast. Using this design can build new classrooms quickly, does not require a lot of human resources, and does not leave construction waste. The design of instant construction of new classrooms in schools, is the right solution as an environmentally friendly method of construction.
