This study aimed to determine hydrocarbon removal in oil-contaminated soil using composting with an amendment of yard waste and rumen waste. Hydrocarbon-contaminated soil samples from a public oil-mining field in Wonocolo District, Bojonegoro, Indonesia, were composted with yard waste (Y), rumen waste (R), and mixed YR in varied compositions. Manual agitation was applied every 3Â days for air supply and homogenization. The experiment was conducted in two replicates in reactors of 3.5Â L capacity for 80Â days. Moisture was kept within the range of 50–60%. Measurements of temperature, pH, and moisture content were done every 3Â days, whereas total Kjeldahl nitrogen (TKN), nitrite, nitrate, total bacterial count, organic carbon, and hydrocarbon concentration were measured every 20Â days. The results showed that the highest hydrocarbon removal efficiency (45.26%) was observed in the reactor containingÂ …
