ANALYSIS OF FLY ASH DISPOSAL PROBLEM IN COAL-FIRED STEAM POWER PLANT: STUDY AT PLTU XYZ, INDONESIA
Coal-fired Steam Power Plant (Indonesian: Pembangkit Listrik Tenaga Uap-PLTU) was built to achieve the national electricity demand which is growing now. Activity running on PLTU generates waste which is categorized into hazardous and toxic substances (B3 waste) in large quantities every day and become an unsolved problem until now. This study was aimed to analyze the main problems related to B3 waste management such as fly ash and bottom ash which generated by PLTU. This study uses primary data derived from interviews with expert stakeholders, which then analyzed by using interpretative structural modeling. The main problems in the fly ash and bottom ash management of PLTU-PT XYZ are open handling system of fly ash and bottom ash, weak regulation of TPS permits by local government, TPS designswhich should be silos that do not interact with water, fly ash and bottom handling which not well planned, fly ash and bottom ash disposal which conduct after piling up thus make an expensive cost, fly ash and bottom ash services which focused on Java and wet waste which cause complicated handling and expensive cost. The problem of linkage is the large quantities of fly ash and bottom ash, the expensive of transportation, the amount of landfill that must be non-permeable but it is so limited, and the expensive cost of picking up from the dump.
