S Sebagai bahan bakar peleburan aluminium, kualitas batubara mempunyai peranan penting, khusus nya pada kadar abu dan kandungan air total. Namun, kondisi stockpile yang tidak ideal dapat menyebabkan perubahan terhadap kadar abu dan kandungan air total. Penelitian ini menggunakan metode komparatif untuk mengetahui hasil perbandingan uji analisis kualitas batubara yang tiba di stockpile hingga sebelum proses peleburan. Dari hasil penelitian ini didapat perubahan kadar abu pada sampel 5.1 sebesar 0,6%, sampel 5.2 sebesar 2,04%, dan 5.3 sebesar 3,28%, dan sampel 5.4 sebesar 2.01%. Sedangkan untuk kandungan air total sampel 5.1 sebesar 1,16 %, sampel 5.2 sebesar 2,01%, sampel 5.3 sebesar 2,41 %, dan sampel 5.4 sebesar 5,55%. Faktor yang mempengaruhi perubahan kadar abu dan kandungan air total pada stockpile disebabkan oleh batubara yang terkontaminasi dengan material non batubara, lamanya penyimpanan batubara di stockpile, kondisi lingkungan stockpile, adanya rembesan air, tidak adanya house keeping dan sistem First In First Out pada stockpile.

A Aluminum smelting as a fuel, coal quality has an important role, especially on the ash content and total moisture. However, the conditions were not ideal stockpile could cause changes to the ash content and a total moisture. This study uses a comparative method to determine the results of comparative testing of coal quality analysis which arrived in the stockpile until the earlier of the smelting process. From these results obtained changing levels of ash in the sample 5.1 by 0.6%, sample 5.2 by 2.04%, sample 5.3 by 3.28%, and sample 5.4 by 2.01%. As for the total moisture sample 5.1 by 1,16%, samples 5.2 by 2.01%, sample 5.3 by 2.41% and sample 5.4 by 5.55%. Factors affecting the change of ash content and total moisture caused by the stockpile of coal contaminated with material non-coal, coal stockpile storage duration, environmental conditions stockpile, the water seepage, no house keeping and system first in first out in the stockpile.
