Optimasi Alat Muat dan Alat Angkut Untuk Meningkatkan Produksi Limestone Setelah Indarung VI Berproduksi Di PT Semen Padang

Abstract

Abstract. Indarung VI factory began production in April 2017, causing an increase in the need for
limestone, which was sourced from the Existing Area, from 679,140 tons to 826,833 tons. This study aims
to find out whether production equipment in the existing area are able to meet these increased needs, and
determine the optimization that must be done so that the needs are met. The approach taken is to make a
simulation that describes the actual conditions (operating patterns, effective hours, productivity of tools) in
the field, to be compared with the production target. Optimization is done by analyzing the productivity of
production equipment and effective hours, compared with their theoretical productivity. After being
simulated, it is known that the production equipment has an actual production capability of 679,140 tons,
with a percentage of the production target of 82%. limestone. This means that production equipment has not
met the production target, so production equipment optimization must be done. Optimization carried out:
Improved work efficiency Improved work efficiency from 58.97% to 82.65%, and redesigning matching
fleet. After the optimization above, the existing area production equipment has a total limestone production
of 840,111 tons per month, with a production achievement of 102%.
