Abstract

PT. Putra Elan Balindo is a company engaged in the mining sector specially the andesite minerals domiciled in Palu City. PT. Putra Elan Balindo located in Watusampu Village, Ulujadi District, Palu City, Central Sulawesi, which has an IUP (Mining Business Permit) with an area of 17.89 Ha. To achieve production targets set by the company using a combination of tools mechanics in the form of Excavator Komatsu PC 400 and Dump Truck Hino FM 260 JD, where there is currently only 1 Excavator while the Dump Truck is 2 are needed with a production target of 20,000 m3 per month and have 1 shift working hours. Based on the results of research carried out for one month, it shows that the productivity of the Komatsu PC 400 Excavator is 174.29 m3 / hour and the Hino FM 260 JD Dump Truck is 197.69 m3 / hour for 2 transport equipment. The cost of owning a Hino FM 260 JD Dump Truck is Rp. 476,190/hour and the cost of owning a Komatsu PC 400 Excavator is Rp. 267,857/hour while operational costs for the Hino FM 260 JD Dump Truck are Rp. 1,862,072/ hour and operational costs for a Komatsu PC 400 Excavator Rp. 2,135,421/hour.

Abstract

Consumer market demand for certain specifications of coal continues to increase every year. However, each coal company has a variety of coal qualities in terms of calorific value, water content, ash content, and total sulfur and so on. PT. Alamjaya Bara Pratama is a coal mining company that has several types of coal products that vary in quality. By coal blending, the aim is to obtain coal product that meet the target with a homogeneous composition and according to consumer coal quality specifications. With the linear programming method for coal blending calculations using the Production and Operation Management - Quantitave Methods software has an influence in maximizing the use of the composition quantity for each type of product (MD and HS) as well as optimizing the quality of the coal blending results. Through POM-QM, it has the advantage of being able to determine the benchmark target value for one of the desired coal quality parameters. With subbitumious coal quality as for the research results are calculations of the final quality for each Mother Vessel, one of which is MV Eastern Camelia with the planning results is (AC 5,0% adb, TS 0,90% adb, GAR 4590 kcal/kg arb) with tonnage requirements for coal products (MD = 29.727,84 MT and HS = 22.772,16 MT). Through the use of linear programming (POM-QM) in calculating coal blending planning, the results are obtained and meet each coal quality parameter limit criterion based on consumer demand.
