ABSTRACT: PT Riung Mitra
Lestari trying to improve the main load tool off high way truck (OHT) from one
of their job site dari salah satu job site owned PT. RML, Job Site Krassi,
North Kalimantan where data showedgains in productivity tools primarily under

productivity improvement tool hauler Cat 777 is 78 bcm / hour of a target of
100 bcm / hour.In percentage only reaches 78% and the target after QCCapplication
is expected to reach 95%. Based on fishbone and pareto analysis major problem
and the dominant causes of the failure in the productivity tool loading and
unloading is less good technique, the second is the lack of a hard material
that serves as mixing and blending. By making improvement in loading technique
and road repair there is productivity improvement 57,3 % dari from previous
dataand 22,8 % improvement from target. The other factor that affected
incapability of production is loss time. After QCC improvement loss time
decreased into 90,14 minutes per days from previously 227,14 minutes / days.
