Effects of Bio-char Application on Mobilization of Organic Matter at Talang Gulo Landfill - Jambi

Abstract

Talang Gulo landfill in Jambi city will no longer be able to accommodate the solid waste because it has reached the maximum capacity. Mobilization of organic matter through the leaching process can cause pollution of water sources and the soil around the landfill. Knowing the potential of organic matter mobilization from the landfill is the first step to anticipating the possibility of pollution in surrounding area. The aim of this study are to identification the potential of organic matter mobilization from the landfill using three-step sequential extraction protocol and to determine the effect of bio-char position application to reduce organic matter mobilization. Batch experiment method used to identify the potential of organic matter mobilization, and the fixed bed column used to identify the effect of bio-char position in the soil. The extract from both experiments was analyzed by UV-VIS spectrophotometry. The results show that the mobilization of organic matter occurs more in acidic conditions. The mobilization of organic matter in acid condition and neutral condition is 45% and 6%, respectively and bio-char position with layer system was more effective to reduce the mobilization of organic matter in the landfill’s soil.
