PERBANDINGAN PRODUKTIVITAS KERJA LAUNCHING METHOD SYSTEM DENGAN MANUAL METHOD PADA PEMASANGAN GELAGAR JEMBATAN

Abstract

Implementation planning is a formulation in the control of the overall construction project activities, so it will get a method or a good technical way so that with limited resources - obtained maximum results. Increase the productivity of work comprehensively to determine the value of the success of a construction project. Success in a project is also determined by equipment resources. The analysis carried out is the planning time and cost of the project, presenting the optimal time period when associated with project costs by way of shortening the completion period After obtaining the optimal time and cost the results are compared with the planning time and costs compiled by the prusahaan, the thing This is to know the time and cost efficient. Then to compile the scheduling needs of the project's daily workforce. From the analysis obtained the efficiency of time achieved by each method is, the time reached by the Manual method with the help of the pulley tool is 91 hours or rounded up to 12 days with the help of 7 workers and 1 foreman, while the time achieved by the use of tools 1 mobile crane that is 27.2 hours or rounded up to 4 days. based on the productivity of the time already achieved each method can be deduced use Launching method system more efficient 8 days in appeal using the Manual method with the help of the pulley tool. The efficiency of labor cost and tools achieved by each method ie, Costs achieved by using manual labor 26,590,200,00 using 7 workers and 1 foreman in 91 hours or rounded up to 12 working days, while the fee which is achieved by using 1 mobile crane device that is 14,071,922,28 in 27,2 hour or d to become 4 working days. The use of more efficient methods in time and the use of a labor force is the method of using a mobile crane/launching method system which can assist contractors to work within the specified time.
