Optimalisasi Produktivitas Alat-Alat Berat Pada Proyek Pembangunan Jalan Tol Medan – Kualanamu - Tebing Tinggi (Studi Kasus)

Abstract

The use of heavy equipment in an poyek requires good management to avoid blosses due to the use of heavy equipment are not coefficients. Selection and determination of the composition of any equipment depends on the characteristics of use, selection and determination of the amount of the right tools so that the equipment can operate effectively, the cost of heavy equipment may be on tap as minimal as possible so it does not result in an error and loss. Given the use of heavy equipment is very expensive on the job toll road project Medan – Kuala Namu - Tebing Tinggi section 3, it is necessary efficiency measures by way of utilizing resources such tools, so this study is intended to analyze the productivity of the machine by using the theory of productivity of the machine, counting theproduction capacity of each machine to be obtained values productivity andallocation needs of heavy equipment required on projects in the review. From the calculation, obtained the productivity of each machine Excavator = 430 m3 / hour, Dump truck = 21.02 m3 / hour, Bulldozer = 126.56 m3 / hour, Vibrator Roller = 137.39 m3 / hour then can each requirement, excavator 6 units, 25 units of dump trucks, bulldozers 4 units, vibrator roller 4 units while on the contractor excavator 8 units, as many as 33 units of dump trucks, bulldozers 4units, a vibrator roller 4 units. Trial calculation of the production machine to take two alternatives. The result of the acquisition of optimum costs required to complete the project work motorway Medan - Kuala Namu - Tebing Tinggi section 3 obtained in the second alternative is alternative 2 is more efficient, because it can save the cost of rental equipment
