PRODUCTIVITY ANALYSIS OF HEAVY EQUIPMENT WORKING TIME ON THE ROAD PRESERVATION PROJECT OF RANTAU-KANDANGAN-DS. BAGAMBIR–HAMBAWANG BEACH–MANTIMIN–PARINGIN
Abstract
Use of heavy equipment influences the smooth implementation of a project. if not used efficiently it can result in results that are not in accordance with the plan. In order for its implementation to be in accordance with the planned time target, it is necessary to pay attention to the quality of the use of the heavy equipment.
In this study, observations and direct interviews were carried out in the field to
obtain data on equipment working hours and the type of heavy equipment used in the project under review. The method used for the calculation is data analysis which includes the type of work, calculation of heavy equipment productivity based on the 2022 AHSP, calculation of working hours of heavy equipment, and calculating the duration of the implementation of each job from the results of the working hours of the equipment obtained.
The results of the analysis of tool productivity calculations obtained productivity values for the sub-base layer work of class B: wheel loader that is 20.1 m/hour, dump truck is 20.0 m/hour, motor grader is m³/hour, vibrator roller is 56.25 m³/hour , tandem roller is 84.3 m/hour, water tank truck is 64.28 m/hour. In the work of the top layer of foundation class A: wheel loader is 20.1 m/hour, dump truck is 20.0 m/hour, motor grader is m³/hour, vibrator roller is 45.0 m/hour, tandem roller is 67.5 m³/ hours, the water tank truck is 64.28 m³/hour. For liquid asphalt-adhesive coating work: asphalt distributor is 4500 liters. In Lapis Aus (AC-WC) work: asphalt finisher is 63.2 , wheel loader is 30.1, asphalt mixing plant is 30 tons/hour, dump truck is 30.3, pneumatic tired roller is 48.0, tandem roller is 30.1 . With heavy equipment working hours for Layer Aggregate Foundation Class B work as a whole is 303 hours (44 days), for Layer Aggregate Foundation Class A work 388 hours (56 days), and for worn-out Liquid Asphalt Work (AC-WC) it is 441 hours (63 days).
