Abstract
Tea dreg is a waste that is often wasted, the utilization of tea waste is still very limited and in a small scope. The field of animal husbandry uses tea as an addition in making compost, besides being used as organic fertilizer, tea dregs can also be used as activated carbon as an adsorbent. In making activated carbon, the content of tea pulp that is taken into account is holocellulose, which is 60.81%. Tea pulp consists of cellulose of 29.42%, and lignin of 36.94%. In making activated carbon, the carbonization process needs to be done. The purpose of this study was to determine the effect of hydrochloric acid (HCl) concentration on the activation of activated carbon from tea dregs on the quality characteristics of activated carbon produced referring to SNI standard No. 06-3730-1995. Tea dregs were carbonized using a furnace at 400 ℃ for 20 minutes with varying concentrations of HCl 0.5 M; 1 M; 1.5 M; 2 M and 2.5 M for 48 hours. The best results were found at 1 M HCl concentration with an iodine absorption value of 896.287 mg/g, moisture content of 8.26%, ash content of 2.91%, volatile matter of 24.33% and fixed carbon of 64.5%.
