It is produced in a large amount, counting up to 23% of the fresh fruit bunch (FFB). The ash content in OPEFB comprises a potassium compound. Potassium can be potentially recovered as potassium carbonate by extracting it with water. This study aims to investigate a method to recover potassium from OPEFB ash as potassium carbonate for further processing into potassium-based fertilizer. This research consists of pyrolysis process of OPEFB into char, then the char is analyzed by TGA in order to determine the ashing temperature. The temperature of 250°C, 400°C and 550°C are chosen for the ashing (combustion) process. The resulted ash is then extracted by water with the Feed to Solvent ratio of 1:4, 1:5, and 1:6, respectively. From the AAS analysis result, the highest potassium concentration is obtained at temperature of 400°C with F:S ratio = 1:6, with the potassium concentration of 49,94 %-w/w. This value is suitable for liquid fertilizer.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research is funded by the P3MI grant program 2017 for the Chemical Engineering Product Design and Development Expertise Group at the Faculty of Industrial Technology, Bandung Institute of Technology.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1757-899X/823/1/012035[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
