The aim of this research is knowing the capability of <em>Bacillus mycoides</em> on degradation petroleum hydrocarbon. The measurement of first sludge TPH was 71.1567%. First TPH was become more liquid than before on 5; 7.5; 10; 12.5 and 15% with fresh soil, bulking agent and <em>Bacillus mycoides</em> was added 10% from medium total weight. Incubation for 14 days gives result decreasing TPH on each medium become 2.3679; 4.5123; 5.9070; 6.0223 and 8.0010% which is first order reaction. Medium 10% on incubation day 14<sup>th</sup>; 17<sup>th</sup>; 22<sup>nd</sup>; 26<sup>th</sup> and 31<sup>st</sup>. On continue, decreasing TPH is 5.9070; 4.5970; 4.0463; 3.7230 and 3.29% with constant rate reaction on 0.0361 /day. GC-MS result sample analysis shows that <em>Bacillus mycoides</em> have an ability to degradation C<sub>19</sub>H<sub>40</sub>; C<sub>21</sub>H<sub>44</sub>; C<sub>24</sub>H<sub>50</sub> and C<sub>28</sub>H<sub>58</sub> with percentage of concentrate decreasing from those compound is 99.32%.</p>}, number={1}, journal={Jurnal Lahan Suboptimal : Journal of Suboptimal Lands}, author={Fanani, Zainal and Yudhono, Bambang and Situmorang, Veriana Romarito}, year={2015}, month={Jul.} }
