Produksi Gas Selama Proses Biodegradasi Heavy Oil Waste dengan Teknik Landfarming
MetadataShow full item record
Bioremediation is defined as biological degradation process of organic or inorganic wastes in a controlled condition to control and reduce their amount in the environment. In this study, the soil which had been poluted by heavy petroleum oil fractions, i.e. heavy oil waste (HOW), was used as sample. The bioremediation technique used in this study is an ex-situ technique. This study was conducted to determine the amount of produced gases during the HOW degaradation process. The highest CO2 production mean was obtained from the bioaugmentation treatment with compost adding, i.e. 244,5 mg/m3. This treatment also produced the highest NO2 production mean of 58,1 μg/m3. While the highest NH3 production was observed in pure HOW bioaugmentation treatment (155,6 μg/m3), and H2S was produced in the highest amount in pure HOW biostimulation treatment (3337,2 μg/m3). The SO2 gas production was not obvious in all treatments. Generally, all graphs of each gas production followed a similar sinusoidal pattern. From these results it can be infered that the degradation process of HOW happened during the treatments.
