Abstract

BUMN) one that moving at limestone mining area. Material purpose burn thattall on tool transports dumptruck t h e r e f o r e shall evaluate to down cost ofmining. Trick to reduce using up fuel it by undertaking analisis factor thatregards it, one that covers grade resistance , rolling resistance , speed, conditionof place job, attitude operator, and quality machine, and method mining one thatare not optimal.This research at focuses on prisoner influence full scale resistanceandand speed to burning fuel on unit dumtruck Catrepillar HD777 and KomatsuHD785 . Of watch result at field is gotten that the greater prisoner full scaleresistannce therefore the greater too fast fueled one is burnt from vehicle andgetting vehicle runaway speed slowing therefore will the greater too fast fueledone be burnt. It is caused because ability Rimpull circumscribed machine to settleprisoner so slows vehicle runaway speed. To result Rimpull one that big, thereforemachine shall be conected with low tooth and with RPM high.Relationship full scale resistance to fuel base analysis statistic withmethod regression linear modestly are as big as 99,013% meanwhile subjectivespeed is with fuel gotten by point determinant coefficient (R 2 ) as big as 0,997%.Base cost standard for fueled dumptruck 775F as big as 51,7 liters / the time ofday, therefore prisoner total maximal one can settle its truck as big as 15 %.
