Abstract
The most popular fly ash application as coal combustion energy waste is as a mixing agent for cemented infrastructure and building construction. However, due to its appropriate various mineral content from vegetation fossil, the usage for fertilizer and soil amelioration agent was tested in small pots on the field. The purpose of the experiment was to confirm the effectivity of fly ash granule application using tapioca flour and sugar cane molasses as granule agents on the soil amelioration function and the sorghum growth, development, and its potential bioethanol yield harvested in the vegetative stage. The granule binding agents source is from agricultural product or byproduct or agricultural waste so that environmental management and the production system of the fly ash granules exhibit the advantage for a sustainable production system. The concentration of 10% of the granule binding agents concentration for the application at a rate of 8 tons ha-1 was effective enough to improve the soil properties, plant growth, and the doubling of bioethanol potential yield as well.
