OPTIMASI JUMLAH TENAGA KERJA OLEH KONTRAKTOR DENGAN METODE SIMPLEKS PADA PROYEK KONSTRUKSI BANGUNAN GEDUNG SARANA PENUNJANG RSUD PRAMBANAN
Abstract
In construction projects, delays are often caused by labor issues, such as a shortage of workers and excessive overtime. Therefore, careful workforce planning is essential to control costs and effort. Optimization is a solution to improve the efficiency of resource use, including labor, time, and cost. The Simplex method, which is used in linear programming, can help in the allocation of resources to achieve optimal results. This study found the optimal labor allocation with 14 workers, 10 blacksmiths, 9 masons, 2 head blacksmiths, 1 head mason, and 6 foremen. The initial labor cost of Rp. 8,180,000,- per day was successfully optimized to Rp. 4,740,000,- per day, resulting in savings of 42.5%. These results show that the Simplex method can improve the efficiency of workforce management without reducing productivity and quality. Research recommends the application of the Simplex method to other jobs and limited resources such as materials, materials and construction equipment.
