bakar batubara cair selain likuifaksi dan coal water fuel. Coal oil mixture (COM)&#13;
merupakan bahan bakar campuran dengan komposisi yang seimbang antara batubara,&#13;
minyak bumi, dan zat additif (Maeda, 1991 : 66).&#13;
Pada penelitian ini, batubara yang digunakan adalah batubara peringkat&#13;
rendah yang di campur dengan zat aditif dan solar. Adapun rasio batubara:solar:zat&#13;
aditif yang digunakan adalah 25%:75%:0% (COM A1), 25%:74%:1%, (COM A2)&#13;
dan 25%:73%:2% (COM A3).&#13;
Hasil penelitian menunjukkan karakteristik viskositas yang di ujikan pada&#13;
COM A1, A2, A3 lebih mendekati MDO dibandingkan HFO sebagaimana standar&#13;
ISO 8217 2010 viskositas MDO (Marine Diesel Oil) dengan batas maksimal 11 cSt&#13;
pada suhu 400c. Adapun nilai kalori COM A1, A2, A3 lebih rendah dibandingkan&#13;
MDO dikarenakan pemanfaatan batubara kalori rendah dalam campurannya.</mods:abstract><mods:classification authority="lcc">TN Mining engineering.
