Abstract
Kegiatan pengupasan dan pengangkutan overburden di PT. Putra Muba Coal mengoperasikan alat gali muat berupa excavator dan alat angkut berupa dump truck. Pada kegiatan ini sering terdapatnya waktu tunggu terhadap alat gali muat sehingga mengakibatkan ketidakserasian kerja alat gali muat dan alat angkut. Untuk meningkatkan target produksi tersebut maka perlu dilakukannya peningkatan terkait efisiensi waktu kerja dengan cara mengoptimalkan waktu kerja seperti waktu istirahat, pergantian shift, waktu hujan, dan lainnya. Kemudian mengamati jumlah pengisian bucket excavator ke dump truck, dimana dari hasil pengamatan jumlah pengisian excavator Sany SY 365 H sebanyak 5 pengisian, untuk jumlah pengisian bucket excavator Hyundai HX340S sebanyak 5 pengisian, kemudian Hyundai R495LVS sebanyak 3 pengisian, dan jumlah pengisian bucket excavator XCMG XE370CA sebanyak 5 pengisian. Produktivitas pengupasan overburden aktual alat gali muat excavator Sany SY 365 sebesar 301,07 BCM/jam, excavator Hyundai HX340S sebesar 134,05 BCM/Jam, excavator R495LVS sebesar 148,38 BCM/Jam, dan excavator XCMG XE370CA sebesar 168,23 BCM/Jam. Kemudian produktivitas pengupasan overburden aktual alat angkut untuk dump truck FAW 340 di Fleet 1 sebesar 38,92 BCM/Jam, dump truck FAW 380 di Fleet 2 sebesar 17,42 BCM/Jam, dump truck HOWO 500 di Fleet 3 sebesar 79,37 BCM/Jam, dan dump truck FAW 340 di Fleet 4 sebesar 66,96 BCM/Jam. Faktor-faktor yang mempengaruhi produktivitas dan kesediaan alat gali muat dan alat angkut adalah efisiensi kerja, cycle time alat mekanis, kondisi jalan angkut, faktor pengisian bucket. Berdasarkan efisiensi kerja yang di dapat yaitu 70 %/bulan dan waktu hambatan sebesar 30 %.
