The construction of Mainroad Section X of Pandaan-Malang Toll Road requires of heavy equipment for excavation and embankment works. The type and number of the heavy equipment can be varied depending upon the construction volume, equipment capacity, and the budget. Therefore, the combination of heavy equipment must be chosen carefully to minimize the cost. This study aims to determine the optimum number of heavy equipment combinations with constraints of work volume, schedule, and resources availability to minimize the construction cost. The data needed is site lay-out plan, cross section of the road, project time schedule, specifications of the heavy equipment, and the resources unit price. The method for optimization is Linear Programming using Simplex Method. The results shows that the optimum combination of heavy equipment for excavation work are 14 units of bulldozer type Zoomlion ZD160-3, 5 unit excavator type Komatsu PC200-8MO, and 19 units dump trucks type Mitsubishi Fuso-FN627 at Rp 14.839.362.044,00. As for the embankment work, the optimum equipment are 5 units excavators type Komatsu PC200-8MO, 19 units of dump truck type Mitsubishi Fuso-FN627, 19 units of motor grader type Caterpillar 120K, 18 units of sheep foot roller type Ammann ASC-200, and 23 units of water tank truck type Mitsubishi-125HD at Rp 22.979.058.760,00.
