ABSTRACT

Elephant grass (Pennisetum Purpureum) is one type of underutilized plant. Grass is only used as fodder and is often considered a disruptive plant whereas elephant grass contains a high level of cellulose at 40.58%. plants that have high cellulose levels can be used as raw materials for the manufacture of activated carbon. Carbon is one of the materials in the form of granules or powders and the use of activated carbon is quite extensive, both in large and small industries. In addition to plants, activated carbon can be made from raw materials derived from animals, waste or minerals containing carbon such as: bones, softwood, husks, corn cobs, coconut shells, coconut husks, cane milling pulp, paper making pulp, sawdust, hardwood and coal. This study aims to determine the influence of the type and concentration of activator substances on the process of making activated carbon with an active temperature of 600, 700, 800 and a concentration of 0.2M 0.3M 0.4M 0.5M and 0.6M, the process of making activated carbon is carried out with a 24-hour activation time, a carbonization temperature of 750oC, a carbonization time of 15 minutes, and an active carbon size of 200 meshes and types of activator substances (HCl, NaOH, and NaCl) with concentrations (0.2M 0.3M 0.4M 0.5M and 0.6M respectively). The results showed volatile matter levels of 2,834%, water content of 4.1%, ash content between 0.271%, and absorption of iodium 1,243.62 mg/g. The optimum condition of activated carbon from elephant grass is in the HCl activator type concentration of 0.6 M.
