Abstract

PT TIMAH (Persero) Tbk is one of the State Owned Enterprises (SOEs) in the field of tin mines located in the province of Bangka Belitung. Alluvial tin ore mining on the seabed is done using Dredger, cutter suction dredges, and Bucket Wheel Drage and Cutter Suction for stripping overburden. More emphasis tin ore mining production by using Cutter Suction Dredger. A layer of soil that is too thick and covering material resulting sludge, It causes the excavation become less efficient, and the operating costs of extracting and washing increase. The rate of transfer of land Cutter Suction Dredger of 200 m3 / h and the target hours of the road about 500 hours per month can not be achieved with good in these condition. Stripping Cutter Suction then need to be enabled to help excavate soil over a thick, so it can help the performance Cutter Suction Dredger in the process of excavation. Cutter Suction Stripping using a cutter to cut the layer of soil and then pump to suck soil and dispose of land that has been excavated. Stripping Cutter Suction Dredger combination has optimum soil excavation removal rate of 1050 m3 / h, so the Cutter Suction Dredger Stripping can help in increasing the productivity of the soil removal. Mining using a ship combination of better than mining ship without combinations. Combination vessel can also affect the cost of the mining operation. The total cost required for mining use a combination of the ship in a more efficient work plan of Rp. Rp 7.045.313.574,34. In other words, be saving about 37% of the cost of the mining operation without the combination.
