<![CDATA[The purpose of this experiment was to prepare and characterize activated carbon from Mangosteen peels (Garcinia mangostan L). Carbon from Mangosteen peels was prepared by pyrolysis method at 300°C for 1 hour. This carbon was activated by chemical activation process with various activating reagent and concentration. The activated carbon was characterized using Indonesian Industry Standard (SNI 06-3730-1995), that is maximum water content of 15%, maximum vapor content of 25%, maximum ash content of 10% and bounded carbon content at least 65%. The results showed that the highest bounded carbon content obtained from pyrolysis was 78,09%. The best activating reagent was HCl with concentration of 4N that improved the bounded carbon to 87,84%. The water content, ash content, and vapor content of activated carbon was obtained as follows, 6,11%, 1,97%,and 10,19%. Based on this results, activated carbon of mangosteen peels conformed the (SNI 06-3730-1995) values and will be applied as a thermoelectric material.]]>
