ANALISIS HUBUNGAN TOTAL RESISTANCE DAN KECEPATAN TERHADAP KONSUMSI BAHAN BAKAR DUMPTRUCK KOMATSUHD785DAN CATERPILLAR HD777DI PT. SEMEN PADANG

Abstract

BUMN) one that moving at limestone mining area. Material purpose burn that
tall on tool transports dumptruck t h e r e f o r e shall evaluate to down cost of
mining. Trick to reduce using up fuel it by undertaking analisis factor that
regards it, one that covers grade resistance , rolling resistance , speed, condition
of place job, attitude operator, and quality machine, and method mining one that
are not optimal.
This research at focuses on prisoner influence full scale resistance
andand speed to burning fuel on unit dumtruck Catrepillar HD777 and Komatsu
HD785 . Of watch result at field is gotten that the greater prisoner full scale
resistannce therefore the greater too fast fueled one is burnt from vehicle and
getting vehicle runaway speed slowing therefore will the greater too fast fueled
one be burnt. It is caused because ability Rimpull circumscribed machine to settle
prisoner so slows vehicle runaway speed. To result Rimpull one that big, therefore
machine shall be conected with low tooth and with RPM high.
Relationship full scale resistance to fuel base analysis statistic with
method regression linear modestly are as big as 99,013% meanwhile subjective
speed 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 of
day, therefore prisoner total maximal one can settle its truck as big as 15 %.
