Abstrak

The growing demand for fast and efficient construction of low-income housing has driven innovations in construction execution methods. One emerging approach is the use of on-site precast sloof systems, which are cast and installed directly at the project site. This study aims to compare the efficiency of time, labor, and cost between conventional sloof and on-site precast sloof methods in small-scale housing developments. An experimental method was employed, utilizing eight repetitions for each method, with measurements encompassing execution time, labor requirements (both skilled and unskilled), and total costs. The results indicate that the precast method is more time-efficient, with a 13.83% reduction, and requires 22.1% less skilled labor. However, it also leads to a 40.5% increase in demand for unskilled labor. In terms of cost, the precast sloof method was 23% more expensive, with a cost-efficiency ratio of 1.23 compared to the conventional method. Nevertheless, the advantages in execution speed and reduced reliance on skilled workers make on-site precast sloof a strategic alternative for low-cost housing projects, especially in areas with limited skilled labor availability.
