The research results found that the value of workload efficiency is and the value of conveyance is ; while the productivity of loading equipment is 5,055 BCM/hour and conveyance is 5,189 BCM/hour; furthermore, the match factor level of the equipment is . However, the match factor level is still below the standard. Thus, further research is required to determine the appropriate strategy to make the equipment's match factor level equal to one. | Heavy equipment efficiency productivity and compatibility of coal mine overburden work in east Kalimantan
