In this study, to determine the characteristics of charcoal from the manufacture using a modification tool, and to determine the effect of system density variation. Activated charcoal is made through several stages namely, dehydration, carbonization and activation. The use of the modifikation at the carbonization stage will result in different activated charcoal. The activation proses used in chemical activation by immersing the charcoal in a ZnCl2 activator solution. The charcoal massa period used is 1:1 with the charcoal massa : the activator period. Comparison of the massa used to produce increased system density of 2%, 4%. 6%, 8%, and 10%. The activation time used in accordance with the previous study was 8 hours. The active charcoal made using the modified means is obtained for the optimum 2% effect of system density at 8 hours of activation time. Characteristic values obtained at 2% system density were 3.67% moisture content, ash content 13.5%, iod absorption 277 mg / g, and density 0.31 g / mL.Keyword:activated charcoal, modifiers, chemical activation

Some research proved that activated carbon could be made from organic materials or anorganic material with very high carbon content. The exist research of activated carbon from coconut shell, bagasse, cassava peel. In fact, there are a lot of material can be used as raw material, like cassava rods wastebecause the amount is very abundant and has not been widely used. This research aims toreceive the right conditionsin the manufacture of activated charcoal from cassava stem wastewith variations in concentration and time of activationwith chemical activation methodsusing a hydrochloric acid activatorto obtain activated charcoal products that fulfill the standards. Making activated charcoal begins withdehydrate the stem in the sun for around 2 days. The second is make cassava charcoal by installing a series of clinker drum cassava stems. The third is charcoal stem activationwith the size 100 mesh, mix charcoal with Hydrochloric Acidinto erlenmeyerwith concentration 1,5N; 2N; 2,5N; 3N; and 3,5Nthen stir with Heating Magnetic Stirrer, 105 ºC, during 2,5 hours, 3 hours, 3,5 hours, 4 hours, 4,5 hours. The results obtained by the best active charcoalat concentration3 Nwith activation time 4,5 hours, ash content 0.8%, andabsorption of iodine 399,67 mg/g.

This study aims to determine the effect of variations of the sugar palm activation temperature on the functional groups of activated charcoal from palm bunch (Arengga Pinnata Merr) with potassium silicate (K2SiO3) activation agent. The process of making an chemically activated charcoal is divided into three stages, firstly the preparation stage of preparing the palm bunches into cutting, washing and drying, secondly carbonitation stage at a temperature of 300oC – 400oC about ± 8 hours and the chemical activation stage. Potassium silicate K2SiO3 is a new activation agent that is used to activate an activated charcoal by using 2 : 1 ratio (K2SiO3: activated palm bunches) for 12 hours and an activation temperature of 600oC, 650oC, 700oC, 750oC, and 800oC for 30 minutes. Characterization of activated charcoal from palm bunches was tested by using Fourier Transform Infrared (FTIR). The FTIR spectrum shows that the activated charcoal produced has an absorption pattern with the types of bonds are C≡C (Alkuna), C=C (Aromatic Rings), C-H (Alkanes), Si-O and C-H (Alkanes). The Information was obtained that a good activation temperature for activated charcoal of palm  bunches was seen at temperatures of 650oC, 700oC and 750oC with the largest IR absorption was seen at temperatures of 700 oC.

Characterization Of Activated Carbon

Carbonization of carbon obtained from plantain (Musa paradisiaca) stem was achieved at a temperature of 400°C for one hour. The carbonized carbon was divided into two parts to be activated separately. The activated carbon CPPAC (carbonized plantain phosphoric acid activated carbon) and CPZAC (carbonized plantain zinc chloride activated carbon) were produced via the chemical activation process using H3PO4 and ZnCl2. Characterization of pH, bulk density, moisture content, ash content, volatile matter, iodine number, and oxygen functional group was conducted. When comparing the surface properties of both CPPAC and CPZAC with the untreated plantain carbon (UPC), it was observed that there existed significant differences in all properties with the exemption of carboxylic group for CPPAC and phenolic group for both CPPAC and CPZAC, thus signifying that a chemical transformation did occur. When comparing the results obtained from CPPAC to that of CPZAC, CPPAC was more preferable for adsorption due to its low bulk density, low ash content, and high iodine value, signifying thus that the activating agents both reacted differently with the plantain stem.
