Utilization of FABA Waste from coal combustion at the PLTU Air Anyir as an alternative to local construction materials

FABA (fly ash and bottom ash) is a by-product of coal combustion at the Air Anyir steam power plant (PLTU), in the Province of the Bangka-Belitung Islands. The waste generated from this PLTU always increases every year, but its utilization is not getting the attention of the related parties. In connection with these reasons, the aim of this study was to analyse the advantages and disadvantages of FABA utilization and to identify barriers in applying the use of FABA as an alternative to local construction materials. The in-depth interview method was selected in this study to obtain detailed information regarding FABA issues. The interviewees were derived from the internal and external parties of the PLTU Air Anyir. The interview results were analysed using the narrative method. The results of this study are expected to encourage relevant parties to use FABA as an alternative substitute for construction materials.
