Abstract

Geometri jalan yang tidak baik menyebabkan keterlambatan suatu alat angkut tersebut yang berdampak terhambatnya laju produksi sehingga waktu edar alat angkut tersebut tidak efektif. Berdasarkan pengukuran geometri dari jalan angkut, lebar jalan aktual adalah 4,16-9,83 meter sedangkan lebar teoritis jalan lurus adalah 5 meter untuk satu jalur dan 8,75 meter untuk dua jalur. Lebar jalan tikungan aktual berkisar 4,58-9,83 meter sedangkan secara teoritis lebar jalan tikungan adalah 6,48 meter untuk satu jalur dan 11,34 meter untuk dua jalur. Grade jalan aktual adalah 0,74%-13,22% sedangkan grade jalan yang ideal adalah 10%. Cross Slope aktual berkisar 0,02%-2,95% sedangkan cross slope ideal adalah 2%. Superelevasi aktual 0,48%-2,96% sedangkan superelevasi rencana adalah 4%. Perhitungan produktivitas dump truck iveco 682 aktual sebesar 33,71 bcm/jam, produktivitas dump truck iveco 682 dengan waktu edar teoritis sebesar 46,62 bcm/jam, produktivitas teoritis dump truck iveco 682 setelah perbaikan geometri jalan adalah 48,78 ton/hari.

Abstract

PT. Lautan Hutan Lestari is a coal mining company operating in Lemo Village, Central Kalimantan. The company targets production in May 2024 of 98.852 tonnes with an hourly target of 130 tonnes/hour. The actual coal production data shows production of 62.206 tonnes, the achievement of production is only 62,92% of the planned target. This study aims to increase the productivity of the coal getting unit, analyse the factors that cause the non-achievement of Komatsu PC 300 excavator productivity and provide improvement efforts to meet the planned production targets. Equipment analysis was carried out on a combination of mechanical tools used during the study, namely Excavator Komatsu PC 300. The research method used in this research is quantitative method. There are 2 scenarios that can be used to increase tool productivity in coal getting activities. Scenario 1 is a reduction in avoidable obstacle time to increase work efficiency so that productivity becomes 169,55 Tonnes/hour, this scenario has reached the production target but can still be improved. Scenario 2 is an improvement in obstacle time to increase work efficiency and fleet matching with the addition of conveyance units so that the resulting productivity can increase significantly by 222,22 Tonnes Keywords : Coal Getting., Excavator, Match Factor, Productifity
