Abstract

Fulfilling the annual mining production target of PT Prima Timah Utama based on the 2019 Work Plan and Budget of 1,100,000 m3 requires the procurement of adequate mining equipment both in terms of quantity and production capacity, especially excavators. The equipment procurement plan is estimated by calculating the need for tools using a sample of 30 distribution time data, 9 time constraints data, and some supporting calculation data that results in tool requirements. The cost of ownership of the equipment to be compared with the rental cost is obtained from the purchase price, interest, residual value and economic life of the equipment. The cost comparison is then analyzed using the Net Present Value method using 6 data in the form of initial investment, residual value, income, operating costs, interest, and economic life. The calculation results show that PT Prima Timah Utama must add 1 unit of CAT 320D2 excavator for stripping overburden and 1 CAT 320D2 excavator unit for digging and washing with an estimated tool cost of Rp. 2.224.076.433,6,- for 2 units of new equipment and Rp. 2.541.131.520,- for 2 units of rental equipment where the difference between the rental and purchase equipment is Rp. 317.055.086,4,- for one year of work. The results of the analysis with the evaluation of NPV investment have a value of Rp." 32.313.773.567,7" or > 0 which states that the investment is declared feasible.
