Analysis of Productivity Synchronization of Barge Transportation Equipment and Crane Loading on Nickel Ore Delivery Activities in PT. Antam Nickel UBP North Maluku

Abstract

Nickel mining activities at PT. ANTAM North Maluku Nickel UBP is closely related to the production and distribution process. To achieve optimal production, nickel ore is loaded or shipped in accordance with the company's production targets. The study aims to determine the compatibility value of barges and crane loading equipment in the shipping process and to determine the factors that affect the productivity of nickel ore shipments. The research method used is descriptive quantitative method, where the analysis process is based on distribution table data, average values, ​​and percentages. This research was conducted at the Tanjung Buli Site in the MV. shipping process. Lumoso Karunia VIII. In this shipment, the stowage plan target is 55255 tons which must be completed within a maximum of 10 days. The results of the calculation of the compatibility of crane loading equipment in MV. Lumoso Karunia VIII and barge transportation have a match factor value of 0.72 or <1. Factors that affect the decline in the shipping process are work efficiency time, the value of the match factor and rainy time. From the calculation results, the work efficiency time obtained is 65.94% or less efficient. The value of the match factor <1 can conclude that the transportation equipment is busy while the loading equipment has a lot of idle time and rain constraints with an average amount of rain time of 206.6 minutes or 3.44 hours. However, the shipping process can reach the production target within 8 days with the capability of loading equipment productivity reaching 6997.95 tons/day.
