Optimalisasi Produksi Alat Gali Muat Cat 330 GCOGC-318 dengan Metode Overall Equipment Effectiveness serta Analisis Six Big Losses pada Pengupasan Overburden PT. Caritas Energi Indonesia Kabupaten Sarolangun Provinsi Jambi

Abstract

PT Caritas Energi Indonesia conducts mining using the open pit mining method. PT Caritas Energi Indonesia experienced problems with not achieving production targets. Based on the actual production of PT Caritas Energi Indonesia obtained on the CAT330 Excavator, the average productivity value in July 2021 is 64.745,73 BCM. As for the production of the calculation results of the overall equipment effectiveness value of the CAT330 Excavator in July 2021 with a cumulative percentage of 0.67%, this means that the effectiveness of the CAT330 Excavator in July 2021 is 67%. Then the production calculation based on the overall equipment effectiveness method is obtained with an average productivity in July 2021 for the CAT330 Excavator for 93,225.90 BCM. For the calculation of the analysis of the six big losses, the most dominant loss is reduced speed losses with a cumulative percentage of 98.5%. PT Caritas Energi Indonesia has a production plan target per month with a range of 100,000.00 BCM.So improvements or changes are needed with an increase in the cycletime plan but the use of tools based on the overall equipment effectiveness method is still with a cumulative percentage below the standard <85% with a cumulative percentage of results obtained after repairs of 70%. However, for the production achievement after repair of 104,195.52 BCM, it exceeds the production plan target of PT Caritas Energi Indonesia.
