Abstract

Galam wood (Malaleuca cajuputi) is one of the woody plants that can grow well in the peat swamp environment in South Kalimantan. Research on the production of hydrochar by hydrothermal carbonization process of galam bark for adsorption of sasirangan waste has been carried out. In this study, the influence of processing time of the hydrothermal carbonization on the yield and characteristics of hydrochar was investigated. It was found that the processing time of hydrothermal carbonization is the important factor influencing the hydrochar production. The results of FTIR analysis demonstrated that hydrochar from galam bark had different functional group, which indicated had different characters. The surface morphology of hydrochar and galam bark also showed significant different based on scanning electron microscope (SEM) analysis. The results also showed that hydrochar produced at the longer processing time had significantly higher sasirangan waste adsorption capacity.
