Abstract
Coal usage as a source of energy in Indonesia is increasing nowdays. In 2003, the usage of coal in the electric power plant was about 14.1% of total energy and in 2025, it will be over 34.6% (Yanti, 2009). The increase in coal usage causes the increase of coal ash waste, which was up to 500-1000 ton per day (Said, 2010). The discharged coal waste may cause self burning or self exploding and have negative effect to human health. Therefore, under Indonesian regulation (PP85/1999), coal ash is clasified as hazardous and dangerous waste (Said, 2010).In order to reduce the piling up, coal ash must be utilised. One of potential utilization of coal ash is to convert the ash to become zeolite minerals.
