ABSTRACT
CV. Tirta Baru Laksana is a private company engaged in the mining of
rocks, namely andesite, with a location in Hargorojo Village, Bagelen District,
Purworejo Regency, Central Java Province. The mining system used is an open pit
mining system using themethod Quary.
The problems faced by CV. Tirta Baru Laksana is that the andesite
production target of 7,000 m3/month has not been achieved.
This study aims to analyze the factors that affect the production of
loading and conveyance equipment, to make efforts to increase andesite
production by optimizing the effective working time of loading and conveying
equipment after repair and to analyze the effect of effective time before and after
repairs on work efficiency.
The research method used in this study is the study of literature, direct
observation in the field to collect primary and secondary data. The data obtained
was processed and analyzed data. Factors that affect andesite production activities
are the loading method carried out by using top loading by loading a single
backup which is considered faster and besides that, the working time is less
effective so that it reduces work efficiency. a tool that produces a bucket fill factor
value of 85%. Andesite mining production at CV. Tirta Baru Laksana from a
production target of 7,000 m3/month for 1 unit of excavator Kobelco SK200
amounted to 6,280 m3
/ month for 2 units of conveyances dump truck Hino Dutro
130HD amounted to 6,501 m3
/ month
Efforts to increase production can be done by improving the efficiency
of work, by minimizing the barriers of time working can be suppressed. The
results of the calculation of work efficiency have increased, the loading equipment
increased from 54.1% to 63.3% and transportation equipment increased from
50.5% to 61.1% with increasing work efficiency, the production capacity of
loading equipment increased from 6,280 m3/month to 7,315 m3/month and
transportation equipment increased from 6,501 m3/month to 7,833 m3/month.
