Track: Production Planning and Control

Abstract

Demand for coal in the world today continues to increase, one of which demands coal in Indonesia. The increase in demand for coal will certainly make some producers have to prepare their production capacity to meet the demand for coal, given that coal is currently also used as alternative fuel oil. One of the companies engaged in coal mining in Indonesia is PT. XYZ. The purpose of this study is for PT. XYZ can continue to meet the demand for coal, especially in the future. In this study, researchers used a capacity planning method that aims to meet the optimal production capacity and meet all the demand forecasts in the future. Before capacity planning, demand forecast forecasting is used as a basis for determining future production capacity requirements, forecasting using 5-year historical data starting from 2012 to 2016. Given the predicted demand that has been calculated, the company can find out the required capacity requirement In fulfilling all future requests. The addition of capacity has the cost of investment for the company, for that done the feasibility of investment analysis using a cost-benefit analysis approach. The results of this study indicate that the company needs to increase the production capacity from 13,497,624 tons/year to 18,338,040 tons/year to have optimal production capacity because the capacity can meet the demand of 18,204,390 tons/year in 2021. Investment cost The addition of capacity is feasible because the results of the cost-benefit analysis show the NPV and ROI positive, profitability index and benefit-cost ratio above 1, and payback period under five years
