Abstract

Bukit Asam Ltd. provides coal grades that range from 4001 to 7001 kcal/kg calories. This company's customer is PLTU Suralaya, which has a market demand for the BA brand 48 and parameters such as 30% total moisture, 8% ash, 0.8% total sulfur, and 4800 kcal/kg calories. To optimize the desired blending results, optimization will be carried out using simplex method calculations with the help of the Pom-Qm application for Windows V3. This study aimed to find the percentage of coal blended using the simplex method according to consumer demand contracts and to recommend optimal proportions for blending. The research methodology employed qualitative and quantitative data. The results indicated that the percentages needed to meet the demand for PLTU Suralaya were mine brands MT 47 and AL 53 at 49%, MT 47 at 51%, and AL 53 at 63%. The results of the coal quality test were: total moisture of 29.99%, ash of 3.09%, sulfur of 0.57%, and calories of 4817 kcal/kg. All of them met the demand for PLTU Suralaya.
