Abstract

Fly ash is a solid waste resulting from the use of coal as an energy resource. The potential for fly ash presence in Indonesia is considerable with increased coal consumption where the potential availability of coal ash is 10% of total coal consumption, with 80% details being fly ash. The increase in energy needs in Indonesia will have an impact on the increasing need for coal. Coal production in Indonesia in 2015 amounted to 461 million tons, by 2020 targeted coal production of 550 million tons (ESDM 2020). The potential for coal as an energy resource provides opportunities for the potential presence of fly ash. The chemical composition of fly ash coal ash consists of compounds SiO2, CaO, MgO. From the chemical composition contained in this fly ash, researchers studied the manufacture of fly ash as the raw material of adsorbents with methods thermal activated. In this study the parameters analyzed are the effect of activation temperature and length of time. From the results of the study, the temperature and activation time affects the characteristics of adsorbent from coal ash it can be seen the number of iodine increases in line with the increase in temperature, namely at a temperature 250oC and 3500C iodine number are 635 mg/Kg and 930 mg/ Kg.
