Activated charcoal is a carbon that has a good absorption ability (adsorbent) to molecules in the form of organic and inorganic compounds, both in the form of solutions and gases. Rice husks contain about 37.5% carbon which can be used as a purifier or adsorbent in the form of activated charcoal. With the abundance of rice husk resources and low economic value and utilization that is still less than rice husks, it is necessary to know by the public that this rice husk can be used as activated charcoal.
The activity in this training began with the presentation of material on the introduction of activated charcoal to understand and provide more knowledge to the people of Jabung village about activated charcoal from rice husks. After that, the activity continued with the presentation of material in the form of selling value and utilization of activated charcoal derived from rice husks. Armed with the previous submission, the public was given more insights related to the marketing of activated charcoal products from rice husks. With the implementation of this training, it is hoped that the desire for entrepreneurship will grow and utilize rice husks for the purification of used cooking oil so that later it can become the capital of the entrepreneurial community.
