<p align="justify">Industrial activities, especially oil and gas industry generates waste, whether in the form of solid, liquid and gas. Waste generated must be managed properly to avoid contamination to the environment. Waste that comes from the Waste Water Treatment Plant in the oil industry is sludge Produce water is categorized the <br /> <br /> hazardous waste (hazardous and toxic materials) according to the Government Regulation (PP). The PP 18/1999 revised by PP 85/1999 and categorized as hazardous waste with waste code D220 and D221. Produce water sludge contains <br /> <br /> organik matter, and one of the management of waste containing organik material is composting. This study aims to assess the potential of composting sludge with a view of the C-organic degradation. The results of the initial characterization of the sludge showed the C-organic content in the sludge reaches 51%, and any other organik matter content and heavy metals that must be managed because there are some parameters exceeds the quality standard. Method of composting was done by using stacks and a composter. Techniques performed on stacks of two variations of the addition of compost on the composition of bacterial called petrobacteria. Retrieval of data for the physical parameters of the compost is done by daily <br /> <br /> monitoring while for the retrieval of data on organik matter content, heavy metals TPH, toxicity and moisture content, ash and volatile performed by laboratory analysis. Data processing is done mathematically and to support the calculation and hypothesis test conducted by statistic analysis. Composting carried out for 40 days, <br /> <br /> and the results of laboratory analysis showed the presence of degradation of Corganic concentrations that exist in each of the compost reactor. Composter composting techniques to optimize the results were compared by using the stack. In this technique the addition petroba pile drive the rate of composting efficiency, so the results are more optimal than the stockpile without additional petrobacteria. With the degradation of C-organic in the composting process showed that the sludge can be managed with the Produce water composting<p align="justify">
