The aims of this research is preparation activated carbon from a waste of seed of nyamplung and to know the surface structure of activated carbon of seed shell and also carbon composition contained in nyamplung seed shell activated carbon. The samples were then sieved with a size of 100 mesh and then carbonated using pyrolysis at 200400 ̊C for 7 hours, then activated 10 grams using a 30-minute steam pressure with a temperature range from 600 ̊C, 700 ̊C, 800 ̊C and 900 ̊C. The sample was characterized using SEM, proximate and ultimate analysis methods. The result of analysis is obtained that at temperature 700 ̊C has a very large pore diameter of 46 nm while the result of proximate and ultimate characterization shows the highest carbon content obtained an activation temperature of 800 ̊C: 97,32 %. These results indicate that the pore structure is in the mesopori category.
