SUMMARY Rubber fruit shell (Hevea brasiliensis) is a part of rubber fruit that is not widely used, so it only becomes waste in rubber producing areas. Rubber fruit shell charcoal is used as an adsorbent but has a low surface area. This study aims to increase the surface area of activated carbon by of activation (chemical and physical).
